Iowa Association of REALTORS® REGIONAL MLS Rules Last
Updated 4.1.2022
Note: These rules are intended to include every mandatory MLS Rule of the National
Association of REALTORS. If, however, these rules leave out a mandatory rule of NAR, it
is an inadvertent error. All mandatory MLS Rule required by NAR shall be incorporated
into these rules immediately upon passage by the NAR Board of Directors.
Listing Procedures
Section 1: Listing Procedures
Listings of real or personal property of the following types, which are listed subject to a real
estate broker’s license, and are located within the service area of the multiple listing service, and
are taken by participants on an exclusive right to sell basis, or exclusive agency basis, shall be
delivered to the multiple listing service within 1 business day after all necessary signatures of
seller(s) have been obtained:
(Amended 11/17)
a. single family homes for sale or exchange
b. vacant lots and acreage for sale or exchange
c. two-family, three-family, and four-family residential buildings for sale or exchange
Note 1: The multiple listing service shall not require a participant to submit listings on a form
other than the form the participant individually chooses to utilize provided the listing is of a type
accepted by the service, although a property data form may be required as approved by the
multiple listing service. However, the multiple listing service, through its legal counsel:
may reserve the right to refuse to accept a listing form which fails to adequately protect the
interests of the public and the participants
assure that no listing form filed with the multiple listing service establishes, directly or
indirectly, any contractual relationship between the multiple listing service and the client
(buyer or seller)
The multiple listing service shall accept exclusive right-to-sell listing contracts and exclusive
agency listing contracts, and may accept other forms of agreement which make it possible for the
listing broker to offer compensation to the other participants of the multiple listing service acting
as subagents, buyer agents, or both. (Amended 11/96)
The listing agreement must include the seller’s written authorization to submit the agreement to
the multiple listing service. (Amended 11/96)
The different types of listing agreements include:
exclusive right-to-sell
open
exclusive agency
net
The service may not accept net listings because they are deemed unethical and, in most states,
illegal. Open listings are not accepted, except where required by law, because the inherent
nature of an open listing is such as to usually not include the authority to cooperate and
compensate other brokers and inherently provides a disincentive for cooperation. (Amended
4/92)
The exclusive right-to-sell listing is the conventional form of listing submitted to the multiple
listing service in that the seller authorizes the listing broker to cooperate with and to compensate
other brokers. (Amended 4/92)
The exclusive agency listing also authorizes the listing broker, as exclusive agent, to offer
cooperation and compensation on blanket unilateral bases, but also reserves to the seller the
general right to sell the property on an unlimited or restrictive basis. Exclusive agency listings
and exclusive right-to-sell listings with named prospects exempt should be clearly distinguished
by a simple designation such as a code or symbol from exclusive right-to-sell listings with no
named prospects exempt, since they can present special risks of procuring cause controversies
and administrative problems not posed by exclusive right-to- sell listings with no named
prospects exempt. Care should be exercised to ensure that different codes or symbols are used to
denote exclusive agency and exclusive right-to-sell listings with prospect reservations.
(Amended 4/92)
Note 2: A multiple listing service does not regulate the type of listings its members may take.
This does not mean that a multiple listing service must accept every type of listing. The multiple
listing service shall decline to accept open listings (except where acceptance is required by law)
and net listings, and it may limit its service to listings of certain kinds of property. But, if it
chooses to limit the kind of listings it will accept, it shall leave its members free to accept such
listings to be handled outside the multiple listing service.
Note 3: A multiple listing service may, as a matter of local option, accept exclusively listed
property that is subject to auction. If such listings do not show a listed price, they may be
included in a separate section of the MLS compilation of current listings. (Adopted 11/92)
Delayed Showings: A participant may enter a listing into the MLS as a “delayed showing” if
they desire. This will be entered as an active listing, and the agent must include the following
statement in the very beginning of the public remarks section of the listing:
This home is currently listed as a delayed showing. Under no circumstances will any
showings be allowed until _______ (Date) at ___________ (Time). The sellers will not accept
any proposed purchase agreements/offers earlier than 10 PM or ______ on the first showing
date. Any violations of this rule by the listing agent or seller will result in fines to the listing
agent as follows:
First Offense: $750.00
Second Offense: $1500.00
Third and Subsequent Offense: $5000.00
Prior to the listing being accepted by the service, the seller and listing agent will have to execute
a signed statement attesting they under stand this rule and the consequences for non-compliance.
Section 1.01 Clear Cooperation
Within one (1) business day of marketing a property to the public, the listing broker must submit
the listing to the MLS for cooperation with other MLS participants. Public marketing includes,
but is not limited to, flyers displayed in windows, yard signs, digital marketing on public facing
websites, brokerage website displays (including IDX and VOW), digital communications
marketing (email blasts), multi-brokerage listing sharing networks, and applications available to
the general public. (Adopted 11/19)
Note: Exclusive listing information for required property types must be filed and distributed to
other MLS Participants for cooperation under the Clear Cooperation Policy. This applies to
listings filed under Section 1 and listings exempt from distribution under Section 1.3 of the NAR
model MLS rules, and any other situation where the listing broker is publicly marketing an
exclusive listing that is required to be filed with the service and is not currently available to other
MLS Participants.
Section 1.1: Types of Properties
Following are some of the types of properties that may be published through the service,
including types described in the preceding paragraph that are required to be filed with the service
and other types that may be filed with the service at the participant’s option provided, however,
that any listing submitted is entered into within the scope of the participant’s licensure as a real
estate broker: (Amended 11/91)
residential
motel-hotel
residential income
mobile homes
subdivided vacant lot
mobile home parks
land and ranch
commercial income
business opportunity
industrial
Section 1.1.1: Listings Subject to Rules and Regulations of the Service
Any listing taken on a contract to be filed with the multiple listing service is subject to the rules
and regulations of the service upon signature of the seller(s).
Section 1.2: Detail on Listings Filed with the Service
A listing agreement or property data form, when filed with the multiple listing service by the
listing broker, shall be complete in every detail which is ascertainable as specified on the
property data form. Whether or not a property data form or listing agreement is required to be
furnished to the local board office can be determined at the local board level. Each listing broker
is wholly responsible for submitting all listing data and inputting it into the MLS System.
Section 1.2.0: Accuracy of Listing Data
Participants and subscribers are required to submit accurate listing data and required to correct
any known errors.
Section 1.2.1: Limited Service Listings
Listing agreements under which the listing broker will not provide one, or more, of the following
services:
a) arrange appointments for cooperating brokers to show listed property to potential
purchasers but instead gives cooperating brokers authority to make such appointments
directly with the seller(s)
b) accept and present to the seller(s) offers to purchase procured by cooperating brokers
but instead gives cooperating brokers authority to present offers to purchase directly to the
seller(s)
c) advise the seller(s) as to the merits of offers to purchase
d) assist the seller(s) in developing, communicating, or presenting counter-offers
e) participate on the seller’s(s’) behalf in negotiations leading to the sale of the listed
property.
Limited Service Listings will be identified with an appropriate code or symbol (e.g., LR or LS)
in MLS compilations so potential cooperating brokers will be aware of the extent of the services
the listing broker will provide to the seller(s), and any potential for cooperating brokers being
asked to provide some or all of these services to listing brokers’ clients, prior to initiating efforts
to show or sell the property.
Section 1.2.2: MLS Entry-Only Listings
Listing agreements under which the listing broker will not provide any of the following services:
a) arrange appointments for cooperating brokers to show listed property to potential
purchasers but instead gives cooperating brokers authority to make such appointments
directly with the seller(s)
b) accept and present to the seller(s) offers to purchase procured by cooperating brokers
but instead gives cooperating brokers authority to present offers to purchase directly to the
seller(s)
c) advise the seller(s) as to the merits of offers to purchase
d) assist the seller(s) in developing, communicating, or presenting counter-offers
e) participate on the seller’s(s’) behalf in negotiations leading to the sale of the listed
property
MLS entry only listings will be identified with an appropriate code or symbol (e.g., EO) in MLS
compilations so potential cooperating brokers will be aware of the extent of the services the
listing broker will provide to the seller(s), and any potential for cooperating brokers being asked
to provide some or all of these services to listing brokers’ clients, prior to initiating efforts to
show or sell the property.
Section 1.3: Exempt Listings
If the seller refuses to permit the listing to be disseminated by the service, the participant may
then take the listing (office exclusive) and such listing shall be filed with the service but not
disseminated to the participants. Filing of the listing should be accompanied by certification
signed by the seller that he does not desire the listing to be disseminated by the service.
Note 1: Section 1.3 is not required if the service does not require all (indicate type[s] of
listing[s]) accepted by the service) listings to be submitted by a participant to the service.
Note 2: MLS Participants must distribute exempt listings within (1) one business day once the
listing is publicly marketed. See Section 1.01, Clear Cooperation
Section 1.4: Change of Status of Listing
Any change in listed price or other change in the original listing agreement shall be made only
when authorized in writing by the seller and shall be filed with the service within one business
day after the authorized change is received by the listing broker.
A property is “Active” if it is listed in the MLS, ready to be shown, and there are no accepted
offers on the property.
A property is “Active-Contingent” if 1) there is an accepted offer on the property, 2) there are
unresolved contingencies associated with the accepted offer, 3) the property is still available to
be shown, and 4) backup offers are still being welcomed.
A property is “Pending” if 1) there is an accepted offer on the property, and 2) the seller does not
wish for further marketing of the property or showings. A property is “Sold” where the property
has closed successfully.
Section 1.5: Withdrawal of Listing Prior to Expiration
Listings of property may be withdrawn from the multiple listing service by the listing broker
before the expiration date of the listing agreement, provided notice is filed with the service,
including a copy of the agreement between the seller and the listing broker which authorizes the
withdrawal.
Sellers do not have the unilateral right to require an MLS to withdraw a listing without the listing
broker’s concurrence. However, when a seller(s) can document that his or her exclusive
relationship with the listing broker has been terminated, the multiple listing service may remove
the listing at the request of the seller. (Adopted 11/96)
Section 1.6: Contingencies Applicable to Listings
Any contingency or conditions of any term in a listing shall be specified and noticed to the
participants.
Section 1.7: Listing Price Specified
The full gross listing price stated in the listing contract will be included in the information
published in the MLS compilation of current listings, unless the property is subject to auction.
(Amended 11/92)
Section 1.8: Listing Multiple Unit Properties
All properties which are to be sold or which may be sold separately must be indicated
individually in the listing and on the property data form. When part of a listed property has been
sold, proper notification should be given to the multiple listing service.
Section 1.9: No Control of Commission Rates or Fees Charged by Participants
The multiple listing service shall not fix, control, recommend, suggest, or maintain commission
rates or fees for services to be rendered by participants. Further, the multiple listing service shall
not fix, control, recommend, suggest, or maintain the division of commissions or fees between
cooperating participants or between participants and nonparticipants.
Section 1.10: Expiration of Listings
Listings filed with the multiple listing service will automatically be removed from the
compilation of current listings on the expiration date specified in the agreement, unless prior to
that date the MLS receives notice that the listing has been extended or renewed. (Amended
11/01)
If notice of renewal or extension is received after the listing has been removed from the
compilation of current listings, the extension or renewal will be published in the same manner as
a new listing. Extensions and renewals of listings must be signed by the seller(s) and filed with
the service.
(Amended 11/01)
Section 1.11: Termination Date on Listings
Listings filed with the service shall bear a definite and final termination date, as negotiated
between the listing broker and the seller.
Section 1.12: Service Area
Only listings of the designated types of property located within the service area of the MLS are
required to be submitted to the service. Listings of property located outside the MLS’s service
area will be accepted if submitted voluntarily by a participant, but cannot be required by the
service. (Amended 11/17)
The service area of the IAR Regional MLS is the collective geographic area of the local boards
part of this MLS as recognized by the National Association of REALTORS.
Section 1.13: Listing of Suspended Participants
When a participant of the service is suspended from the MLS for failing to abide by a
membership duty (i.e., violation of the Code of Ethics, association bylaws, MLS bylaws, MLS
rules and regulations, or other membership obligations except failure to pay appropriate dues,
fees, or charges), all listings currently filed with the MLS by the suspended participant shall, at
the participant’s option, be retained in the service until sold, withdrawn or expired, and shall not
be renewed or extended by the MLS beyond the termination date of the listing agreement in
effect when the suspension became effective. If a participant has been suspended from the
association (except where MLS participation without association membership is permitted by
law) or MLS (or both) for failure to pay appropriate dues, fees, or charges, an association MLS is
not obligated to provide MLS services, including continued inclusion of the suspended
participant’s listings in the MLS compilation of current listing information. Prior to any removal
of a suspended participant’s listings from the MLS, the suspended participant should be advised,
in writing, of the intended removal so that the suspended participant may advise his clients.
Section 1.14: Listing of Expelled Participants
When a participant of the service is expelled from the MLS for failing to abide by a membership
duty (i.e., violation of the Code of Ethics, association bylaws, MLS bylaws, MLS rules and
regulations, or other membership obligations except failure to pay appropriate dues, fees, or
charges), all listings currently filed with the MLS by the expelled participant shall, at the
participant’s option, be retained in the service until sold, withdrawn, or expired, and shall not be
renewed or extended by the MLS beyond the termination date of the listing agreement in effect
when the expulsion became effective. If a participant has been expelled from the association
(except where MLS participation without association membership is permitted by law) or MLS
(or both) for failure to pay appropriate dues, fees, or charges, an association MLS is not
obligated to provide MLS services, including continued inclusion of the expelled participant’s
listings in the MLS compilation of current listing information. Prior to any removal of an
expelled participant’s listings from the MLS, the expelled participant should be advised, in
writing, of the intended removal so that the expelled participant may advise his clients.
Section 1.15: Listing of Resigned Participants
When a participant of the service resigns from the MLS, the MLS is not obligated to provide
services, including continued inclusion of the resigned participant’s listings in the MLS
compilation of current listing information. Prior to any removal of a resigned participant’s
listings from the MLS, the resigned participant should be advised, in writing, of the intended
removal so that the resigned participant may advise his clients.
Section 1.16: Property Addresses
At the time of filing a listing, participants and subscribers must include a property address
available to other participants and subscribers, and if an address doesn't exist, a parcel
identification number can be used. Where an address or parcel identification number are
unavailable, the information filed with the MLS must include a legal description of the property
sufficient to describe its location. (Amended 5/21)
Selling Procedures
Section 2: Showings and Negotiations
Appointments for showings and negotiations with the seller for the purchase of listed property
filed with the multiple listing service shall be conducted through the listing broker, except under
the following circumstances:
a) the listing broker gives the cooperating broker specific authority to show and/or
negotiate directly, or
b) after reasonable effort, the cooperating broker cannot contact the listing broker or his
representative; however, the listing broker, at his option, may preclude such direct
negotiations by cooperating brokers. (Amended 4/92)
Section 2.1: Presentation of Offers
The listing broker must make arrangements to present the offer as soon as possible, or give the
cooperating broker a satisfactory reason for not doing so. (Amended 4/92)
Section 2.2: Submission of Written Offers
The listing broker shall submit to the seller all written offers until closing unless precluded by
law, government rule, regulation, or agreed otherwise in writing between the seller and the
listing broker. Unless the subsequent offer is contingent upon the termination of an existing
contract, the listing broker shall recommend that the seller obtain the advice of legal counsel
prior to acceptance of the subsequent offer. (Adopted 11/87)
Participants representing buyers or tenants shall submit to the buyer or tenant all offers and
counter-offers until acceptance, and shall recommend that buyers and tenants obtain legal advice
where there is a question about whether a pre-existing contract has been terminated. (Amended
11/05)
Section 2.3: Right of Cooperating Broker in Presentation of Offer
The cooperating broker (subagent or buyer agent) or his representative has the right to participate
in the presentation to the seller or lessor of any offer he secures to purchase or lease. He does not
have the right to be present at any discussion or evaluation of that offer by the seller or lessor and
the listing broker. However, if the seller or lessor gives written instructions to the listing broker
that the cooperating broker not be present when an offer the cooperating broker secured is
presented, the cooperating broker has the right to a copy of the seller’s or lessor’s written
instructions. None of the foregoing diminishes the listing broker’s right to control the
establishment of appointments for such presentations. (Amended 4/92)
Where the cooperating broker is not present during the presentation of the offer, the cooperating
broker can request in writing, and the listing broker must provide, as soon as practical, written
affirmation stating that the offer has been submitted to the seller, or written notification that the
seller has waived the obligation to have the offer presented. (Amended 11/19)
Section 2.4: Right of Listing Broker in Presentation of Counter-offer
The listing broker or his representative has the right to participate in the presentation of any
counter-offer made by the seller or lessor. He does not have the right to be present at any
discussion or evaluation of a counter-offer by the purchaser or lessee (except when the
cooperating broker is a subagent). However, if the purchaser or lessee gives written instructions
to the cooperating broker that the listing broker not be present when a counter- offer is presented,
the listing broker has the right to a copy of the purchaser’s or lessee’s written instructions.
(Adopted 11/93)
Section 2.5: Reporting Sales to the Service
Status changes, including final closing of sales and sales prices, shall be reported to the multiple
listing service by the listing broker within 24 hours after they have occurred. If negotiations
were carried on under Section 2 a. or b. hereof, the cooperating broker shall report accepted
offers and prices to the listing broker within 24 hours after occurrence and the listing broker
shall report them to the MLS within 24 hours after receiving notice from the cooperating broker.
(Amended 11/11)
Note 1: The listing agreement of a property filed with the MLS by the listing broker should
include a provision expressly granting the listing broker authority to advertise; to file the listing
with the MLS; to provide timely notice of status changes of the listing to the MLS; and to
provide sales information including selling price to the MLS upon sale of the property. If deemed
desirable by the MLS to publish sales information prior to final closing (settlement) of a sales
transaction, the listing agreement should also include a provision expressly granting the listing
broker the right to authorize dissemination of this information by the MLS to its participants.
(Amended 11/01)
Note 2: In disclosure states, if the sale price of a listed property is recorded, the reporting of the
sale price may be required by the MLS.
In states where the actual sale prices of completed transactions are not publicly accessible,
failure to report sale prices can result in disciplinary action only if the MLS:
1. categorizes sale price information as confidential and
2. limits use of sale price information to participants and subscribers in providing real estate
services, including appraisals and other valuations, to customers and clients; and to
governmental bodies and third-party entities only as provided below.
The MLS may provide sale price information to governmental bodies only to be used for
statistical purposes (including use of aggregated data for purposes of valuing property) and
to confirm the accuracy of information submitted by property owners or their
representatives in connection with property valuation challenges; and to third-party entities
only to be used for academic research, statistical analysis, or for providing services to
participants and subscribers. In any instance where a governmental body or third-party
entity makes sale price information provided by the MLS available other than as provided
for in this provision, a listing participant may request the sale price information for a
specific property be withheld from dissemination for these purposes with written
authorization from the seller, and withholding of sale price information from those entities
shall not be construed as a violation of the requirement to report sale prices. (Adopted
11/11)
Note 3: As established in the Virtual Office Website (“VOW”) policy, sale prices can only be
categorized as confidential in states where the actual sale prices of completed transactions are not
accessible from public records. (Adopted 11/11)
Section 2.6: Reporting Resolutions of Contingencies
The listing broker shall report to the multiple listing service within twenty-four (24) hours that a
contingency on file with the multiple listing service has been fulfilled or renewed, or the
agreement cancelled.
Section 2.7: Advertising of Listings Filed With the Service
A listing shall not be advertised by any participant other than the listing broker without the prior
consent of the listing broker.
Section 2.8: Reporting Cancellation of Pending Sale
The listing broker shall report immediately to the multiple listing service the cancellation of any
pending sale, and the listing shall be reinstated immediately.
Section 2.9: Disclosing the Existence of Offers
Listing brokers, in response to inquiries from buyers or cooperating brokers shall, with the
seller’s approval, disclose the existence of offers on the property. Where disclosure is authorized,
the listing broker shall also disclose, if asked, whether offers were obtained by the listing
licensee, by another licensee in the listing firm, or by a cooperating broker. (Amended 11/08).
Section 2.10: Availability of Listed Property
Listing brokers shall not misrepresent the availability of access to show or inspect listed
property.
Section 3: Refusal to Sell
If the seller of any listed property filed with the multiple listing service refuses to accept a
written offer satisfying the terms and conditions stated in the listing, such fact shall be
transmitted immediately to the service and to all participants.
Prohibitions
Section 4: Information for Participants Only
Any listing filed with the service shall not be made available to any broker or firm not a member
of the MLS without the prior consent of the listing broker.
Section 4.1: For Sale Signs
Only the for sale sign of the listing broker may be placed on a property. (Amended 11/89)
Section 4.2: Sold Signs
Prior to closing, only the sold sign of the listing broker may be placed on a property, unless the
listing broker authorizes the cooperating (selling) broker to post such a sign. (Amended 4/96)
Section 4.3: Solicitation of Listing Filed With the Service
Participants shall not solicit a listing on property filed with the service unless such solicitation is
consistent with Article 16 of the REALTORS®’ Code of Ethics, its Standards of Practice, and its
Case Interpretations.
Note: This section is to be construed in a manner consistent with Article 16 of the Code of Ethics
and particularly Standard of Practice 16-4. This section is intended to encourage sellers to permit
their properties to be filed with the service by protecting them from being solicited, prior to
expiration of the listing, by brokers and salespersons seeking the listing upon its expiration.
Without such protection, a seller could receive hundreds of calls, communications, and visits
from brokers and salespersons who have been made aware through MLS filing of the date the
listing will expire and desire to substitute themselves for the present broker.
This section is also intended to encourage brokers to participate in the service by assuring them
that other participants will not attempt to persuade the seller to breach the listing agreement or to
interfere with their attempts to market the property. Absent the protection afforded by this
section, listing brokers would be most reluctant to generally disclose the identity of the seller or
the availability of the property to other brokers.
This section does not preclude solicitation of listings under the circumstances otherwise
recognized by the Standards of Practice related to Article 16 of the Code of Ethics.
Section 4.4: Use of the Terms MLS and Multiple Listing Service
No MLS participant, subscriber, or licensee affiliated with any participant shall, through the
name of their firm, their URLs, their e-mail addresses, their website addresses, or in any other
way represent, suggest, or imply that the individual or firm is an MLS, or that they operate an
MLS. Participants, subscribers and licensees affiliated with participants shall not represent,
suggest, or imply that consumers or others have direct access to MLS databases, or that
consumers or others are able to search MLS databases available only to participants and
subscribers. This does not prohibit participants and subscribers from representing that any
information they are authorized under MLS rules to provide to clients or customers is available
on their websites or otherwise. (Adopted 11/07)
Section 4.5: Services Advertised as "Free"
MLS participants and subscribers must not represent that their brokerage services to a client or
customer are free or available at no cost to their clients, unless the participant or subscriber will
receive no financial compensation from any source for those services. (Amended 11/21)
Division of Commissions
Section 5: Compensation Specified on Each Listing
The listing broker shall specify, on each listing filed with the multiple listing service, the
compensation offered to other multiple listing service participants for their services in the sale of
such listing. Such offers are unconditional except that entitlement to compensation is determined
by the cooperating broker’s performance as the procuring cause of the sale (or lease) or as
otherwise provided for in this rule. The listing broker’s obligation to compensate any cooperating
broker as the procuring cause of the sale (or lease) may be excused if it is determined through
arbitration that, through no fault of the listing broker and in the exercise of good faith and
reasonable care, it was impossible or financially unfeasible for the listing broker to collect a
commission pursuant to the listing agreement. In such instances, entitlement to cooperative
compensation offered through MLS would be a question to be determined by an arbitration
hearing panel based on all relevant facts and circumstances including, but not limited to, why it
was impossible or financially unfeasible for the listing broker to collect some or all of the
commission established in the listing agreement; at what point in the transaction did the listing
broker know (or should have known) that some or all of the commission established in the listing
agreement might not be paid; and how promptly had the listing broker communicated to
cooperating brokers that the commission established in the listing agreement might not be paid.
(Amended 11/98)
In filing a property with the multiple listing service of an association of REALTORS®, the
participant of the service is making blanket unilateral offers of compensation to the other MLS
participants, and shall therefore specify on each listing filed with the service, the compensation
being offered to the other MLS participants. Specifying the compensation on each listing is
necessary, because the cooperating broker has the right to know what his compensation shall be
prior to his endeavor to sell.* (Amended 11/96)
*The compensation specified on listings filed with the multiple listing service shall appear in one
of two forms. The essential and appropriate requirement by an association multiple listing
service is that the information to be published shall clearly inform the participants as to the
compensation they will receive in cooperative transactions, unless advised otherwise by the
listing broker, in writing, in advance of submitting an offer to purchase. The compensation
specified on listings published by the MLS shall be shown in one of the following forms:
1. by showing a percentage of the gross selling price
2. by showing a definite dollar amount (Amended 5/10)
Note: MLSs may also, as a matter of local discretion, allow participants to offer cooperative
compensation as a percentage of the net sales price, with the net sales price defined as the gross
sales price minus buyer upgrades (new construction) and seller concessions (as defined by the
MLS unless otherwise defined by state law or regulation). (Adopted 5/08)
While MLSs are not required to authorize participants to offer cooperative compensation based
on net sale prices, those that do permit such offers must define “seller concessions” for purposes
other than new construction, unless that term is defined by applicable state law or regulation.
The following definition of “seller concessions” is suggested but not required for adoption:
Points paid by seller on behalf of buyer, seller-paid buyer closing costs, cash or cash allowances
not escrowed, down payment assistance, additions or alterations not considered deferred
maintenance, and personal property not usual and customary to such transactions conveyed
from seller to buyer having an agreed upon monetary value. (Adopted 05/12)
The listing broker retains the right to determine the amount of compensation offered to other
participants (acting as subagents, buyer agents, or in other agency or nonagency capacities
defined by law) which may be the same or different. (Amended 11/96)
This shall not preclude the listing broker from offering any MLS participant compensation other
than the compensation indicated on any listing published by the MLS, provided the listing broker
informs the other broker, in writing, in advance of submitting an offer to purchase, and provided
that the modification in the specified compensation is not the result of any agreement among all
or any other participants in the service. Any superseding offer of compensation must be
expressed as either a percentage of the gross sales price or as a flat dollar amount. (Amended
5/10)
Note 1: The association multiple listing service shall not have a rule requiring the listing broker
to disclose the amount of total negotiated commission in his listing contract, and the association
multiple listing service shall not publish the total negotiated commission on a listing which has
been submitted to the MLS by a participant. The association multiple listing service shall not
disclose in any way the total commission negotiated between the seller and the listing broker.
Note 2: The listing broker may, from time to time, adjust the compensation offered to other
multiple listing service participants for their services with respect to any listing by advance
published notice to the service so that all participants will be advised. (Amended 4/92)
Note 3: The multiple listing service shall make no rule on the division of commissions between
participants and nonparticipants. This should remain solely the responsibility of the listing
broker.
Note 4: Multiple listing services, at their discretion, may adopt rules and procedures enabling
listing brokers to communicate to potential cooperating brokers that gross commissions
established in listing contracts are subject to court approval, and that compensation payable to
cooperating brokers may be reduced if the gross commission established in the listing contract is
reduced by a court. In such instances, the fact that the gross commission is subject to court
approval and either the potential reduction in compensation payable to cooperating brokers or the
method by which the potential reduction in compensation will be calculated must be clearly
communicated to potential cooperating brokers prior to the time they submit an offer that
ultimately results in a successful transaction. (Amended 5/10)
Note 5: Nothing in these MLS rules precludes a listing participant and a cooperating participant,
as a matter of mutual agreement, from modifying the cooperative compensation to be paid in the
event of a successful transaction. (Adopted 11/05)
Note 6: Multiple listing services must give participants the ability to disclose to other
participants any potential for a short sale. As used in these rules, short sales are defined as a
transaction where title transfers, where the sale price is insufficient to pay the total of all liens
and costs of sale, and where the seller does not bring sufficient liquid assets to the closing to cure
all deficiencies. Multiple listing services may, as a matter of local discretion, require participants
to disclose potential short sales when participants know a transaction is a potential short sale. In
any instance where a participant discloses a potential short sale, they may, as a matter of local
discretion, also be permitted to communicate to other participants how any reduction in the gross
commission established in the listing contract required by the lender as a condition of approving
the sale will be apportioned between listing and cooperating participants. All confidential
disclosures and confidential information related to short sales, if allowed by local rules, must be
communicated through dedicated fields or confidential “remarks” available only to participants
and subscribers. (Amended 5/09)
Section 5.0.1: Disclosing Potential Short Sales
Participants may, but are not required to, disclose potential short sales (defined as a transaction
where title transfers, where the sale price is insufficient to pay the total of all liens and costs of
sale and where the seller does not bring sufficient liquid assets to the closing to cure all
deficiencies) to other participants and subscribers. (Amended 5/09)
When disclosed, participants may, at their discretion, advise other participants whether and how
any reduction in the gross commission established in the listing contract, required by the lender
as a condition of approving the sale, will be apportioned between listing and cooperating
participants. (Adopted 5/09)
Where participants communicate to other participants how any reduction in the gross
commission established in the listing contract required by the lender as a condition of approving
the sale will be apportioned between the listing and cooperating participants, listing participants
shall disclose to cooperating participants in writing the total reduction in the gross commission
and the amount by which the compensation payable to the cooperating broker will be reduced
within 48 hours of receipt of notification from the lender. (Adopted 5/10)
Section 5.1: Participant as Principal
If a participant or any licensee (or licensed or certified appraiser) affiliated with a participant has
any ownership interest in a property, the listing of which is to be disseminated through the
multiple listing service, that person shall disclose that interest when the listing is filed with the
multiple listing service and such information shall be disseminated to all multiple listing service
participants.
Section 5.2: Participant as Purchaser
If a participant or any licensee (including licensed and certified appraisers) affiliated with a
participant wishes to acquire an interest in property listed with another participant, such
contemplated interest shall be disclosed, in writing, to the listing broker not later than the time an
offer to purchase is submitted to the listing broker. (Adopted 2/92)
Section 5.3: Dual or Variable Rate Commission Arrangements
The existence of a dual or variable rate commission arrangement (i.e., one in which the
seller/landlord agrees to pay a specified commission if the property is sold/leased by the listing
broker without assistance and a different commission if the sale/lease results through the efforts
of a cooperating broker; or one in which the seller/landlord agrees to pay a specified commission
if the property is sold/leased by the listing broker either with or without the assistance of a
cooperating broker and a different commission if the sale/lease results through the efforts of a
seller/landlord) shall be disclosed by the listing broker by a key, code, or symbol as required by
the MLS. The listing broker shall, in response to inquiries from potential cooperating brokers,
disclose the differential that would result in either a cooperative transaction or, alternatively, in a
sale/lease that results through the efforts of the seller/landlord. If the cooperating broker is a
buyer/tenant representative, the buyer/tenant representative must disclose such information to
their client before the client makes an offer to purchase or lease. (Amended 5/01)
Section 5.4: Display of Listing Broker's Offer of Compensation
Participants and subscribers who share the listing broker's offer of compensation for an active
listing must display the following disclaimer or something similar.
The listing broker's offer of compensation is made only to participants of the MLS where
the listing is filed. (Amended 11/21)
Section 6: Service Fees and Charges
The services charges and fees are explained below
The following service charges for operation of the multiple listing service are in effect to defray
the costs of the service and are subject to change from time to time in the manner prescribed:
Initial Participation Fee: An applicant for participation in the service may be required to pay an
application fee as determined by their local board.
Note: The initial participation fee shall approximate the cost of bringing the service to the
participant.
Recurring Participation Fee: The annual participation fee of each participant shall be an
amount equal to $24/month times each salesperson and licensed or certified appraiser who has
access to and use of the service, whether licensed as a broker, sales licensee, or licensed or
certified appraiser who is employed by or affiliated as an independent contractor with such
participant. Payment of such fees shall be made on or before the first day of the fiscal year of the
multiple listing service. Fees shall be prorated on a monthly basis.
In August 2018, the NAR Leadership Team made additional revisions to the Model MLS Rules
and Regulations. The language in the paragraph below will appear different from the printed
version of the Handbook on Multiple Listing Policy.
However, MLSs must provide participants the option of a no-cost waiver of MLS fees, dues, and
charges for any licensee or licensed or certified appraiser who can demonstrate subscription to a
different MLS or CIE where the principal broker participates. MLSs may, at their discretion,
require that broker participants sign a certification for nonuse of its MLS services by their
licensees, which can include penalties and termination of the waiver if violated.* (Amended 5/18
and 8/18 [Leadership Team])
Note 1: A multiple listing service may elect to have such fees payable on a quarterly or even on
a monthly basis. However, added administrative services are necessitated by increased frequency
of such payments.
Note 2: Multiple listing services that choose to include affiliated unlicensed administrative and
clerical staff, personal assistants, and/or individuals seeking licensure or certification as real
estate appraisers among those eligible for access to and use of MLS information as subscribers
may, at their discretion, charge recurring fees. (Amended 11/17)
*Note: Mandatory waiver provision is effective no later than July 1, 2018.
Compliance With Rules
Section 7: Compliance With Rules - Authority to Impose Discipline
By becoming and remaining a participant or subscriber in this MLS, each participant and
subscriber agrees to be subject to the rules and regulations and any other MLS governance
provision. The MLS may, through the administrative and hearing procedures established in these
rules, impose discipline for violations of the rules and other MLS governance provisions.
Discipline that may be imposed may only consist of one or more of the following:
a) letter of warning
b) letter of reprimand
c) attendance at MLS orientation or other appropriate courses or seminars which the
participant or subscriber can reasonably attend taking into consideration cost, location, and
duration
d) appropriate, reasonable fine not to exceed $15,000
e) suspension of MLS rights, privileges, and services for not less than thirty (30) days nor
more than one (1) year
f) termination of MLS rights, privileges, and services with no right to reapply for a
specified period not to exceed three (3) years. (Revised 11/14)
Note 1: A participant (or user/subscriber, where appropriate) can be placed on probation.
Probation is not a form of discipline. When a participant (or user/subscriber, where appropriate)
is placed on probation the discipline is held in abeyance for a stipulated period of time not longer
than one (1) year. Any subsequent finding of a violation of the MLS rules during the
probationary period may, at the discretion of the Board of Directors, result in the imposition of
the suspended discipline. Absent any subsequent findings of a violation during the probationary
period, both the probationary status and the suspended discipline are considered fulfilled, and the
individual’s record will reflect the fulfillment. The fact that one or more forms of discipline are
held in abeyance during the probationary period does not bar imposition of other forms of
discipline which will not be held in abeyance. (Revised 05/14)
Note 2: MLS participants and subscribers can receive no more than three (3) administrative
sanctions in a calendar year before they are required to attend a hearing for their actions and
potential violations of MLS rules, except that the MLS may allow more administrative sanctions
for violations of listing information provided by participants and subscribers before requiring a
hearing. The MLS must send a copy of all administrative sanctions against a subscriber to the
subscriber’s participant and the participant is required to attend the hearing of a subscriber who
has received more than three (3) administrative sanctions within a calendar year. (Adopted
11/20)
Section 7.1: Compliance With Rules
The following action may be taken for noncompliance with the rules:
a) for failure to pay any service charge or fee within one (1) month of the date due, and
provided that at least ten (10) days’ notice has been given, the service shall be suspended
until service charges or fees are paid in full
b) for failure to comply with any other rule, the provisions of Sections 9 and 9.1 shall
apply
Note: Generally, warning, censure, and the imposition of a moderate fine are sufficient to
constitute a deterrent to violation of the rules and regulations of the multiple listing service.
Suspension or termination is an extreme sanction to be used in cases of extreme or repeated
violation of the rules and regulations of the service. If the MLS desires to establish a series of
moderate fines, they should be clearly specified in the rules and regulations. (Amended 11/88)
Section 7.2: Applicability of Rules to Users and/or Subscribers
Non-principal brokers, sales licensees, appraisers, and others authorized to have access to
information published by the MLS are subject to these rules and regulations and may be
disciplined for violations thereof provided that the user or subscriber has signed an agreement
acknowledging that access to and use of MLS information is contingent on compliance with the
rules and regulations. Further, failure of any user or subscriber to abide by the rules and/or any
sanction imposed for violations thereof can subject the participant to the same or other discipline.
This provision does not eliminate the participant’s ultimate responsibility and accountability for
all users or subscribers affiliated with the participant. (Adopted 4/92)Section 8: Meetings of
MLS Committee
The multiple listing service committee shall meet for the transaction of its business at a time and
place to be determined by the committee or at the call of the chairperson. The committee will
consist of (2) members of each local board part of the IAR Regional MLS, who shall be voting
members. Each executive officer will be a non-voting member of the committee. These
members will serve two-year terms and shall annually select a chair and vice-chair. Committee
meetings may be held virtually by audio or video means, so long as each member of the
committee can simultaneously hear and talk to one another.
Section 8.1: Meetings of MLS Participants
The committee may call meetings of the participants in the service to be known as meetings of
the multiple listing service.
Section 8.2: Conduct of the Meetings
The chairperson or vice chairperson shall preside at all meetings or, in their absence, a temporary
chairperson from the membership of the committee shall be named by the chairperson or, upon
his failure to do so, by the committee.
Enforcement of Rules or Disputes
Section 9: Consideration of Alleged Violations
The committee shall give consideration to all written complaints having to do with violations of
the rules and regulations. By becoming and remaining a participant, each participant agrees to be
subject to these rules and regulations, the enforcement of which are at the sole discretion of the
Committee (Board of Directors). (Amended 5/18)
When requested by a complainant, the MLS will process a compliant without revealing the
complainant’s identity. If a complaint is subsequently forwarded to a hearing, and the original
complainant does not consent to participating in the process, the MLS will appoint a
representative to serve as the complainant. (Amended 11/20)
Section 9.1: Violations of Rules and Regulations
If the alleged offense is a violation of the rules and regulations of the service and does not
involve a charge of alleged unethical conduct or request for arbitration, it may be
administratively considered and determined by the multiple listing service committee, and if a
violation is determined, the committee may direct the imposition of sanction, provided the
recipient of such sanction may request a hearing before the professional standards committee of
the association in accordance with the bylaws and rules and regulations of the association of
REALTORS® within twenty (20) days following receipt of the committee’s decision. (Amended
11/96)
If, rather than conducting an administrative review, the multiple listing committee has a
procedure established to conduct hearings, the decision of the multiple listing committee may be
appealed to the board of directors of the association of REALTORS® within twenty (20) days of
the tribunal’s decision being rendered. Alleged violations involving unethical conduct shall be
referred to the association’s grievance committee for processing in accordance with the
professional standards procedures of the association. If the charge alleges a refusal to arbitrate,
such charge shall be referred directly to the board of directors of the association of
REALTORS®. (Amended 2/98)
Section 9.2: Complaints of Unethical Conduct
All other complaints of unethical conduct shall be referred by the committee to the secretary of
the association of REALTORS® for appropriate action in accordance with the professional
standards procedures established in the association’s bylaws. (Amended 11/88)
Section 9.3: Complaints of Unauthorized Use of Listing Content
Any participant who believes another participant has engaged in the unauthorized use or display
of listing content, including photographs, images, audio or video recordings, and virtual tours,
shall send notice of such alleged unauthorized use to the MLS. Such notice shall be in writing,
specifically identify the allegedly unauthorized content, and be delivered to the MLS not more
than sixty (60) days after the alleged misuse was first identified. No participant may pursue
action over the alleged unauthorized use and display of listing content in a court of law without
first completing the notice and response procedures outlined in this Section 9.3 of the MLS rules.
Upon receiving a notice, the committee (Board of Directors) will send the notice to the
participant who is accused of unauthorized use. Within ten (10) days from receipt, the participant
must either: 1) remove the allegedly unauthorized content, or 2) provide proof to the committee
(Board of Directors) that the use is authorized. Any proof submitted will be considered by the
Committee (Board of Directors), and a decision of whether it establishes authority to use the
listing content will be made within thirty (30) days.
If the Committee (Board of Directors) determines that the use of the content was unauthorized,
the Committee (Board of Directors) may issue a sanction pursuant to Section 7 of the MLS rules,
including a request to remove and/or stop the use of the unauthorized content within ten (10)
days after transmittal of the decision. If the unauthorized use stems from a violation of the MLS
rules, that too will be considered at the time of establishing an appropriate sanction.
If after ten (10) days following transmittal of the Committee’s (Board of Director’s)
determination the alleged violation remains uncured (i.e. the content is not removed or the rules
violation remains uncured), then the complaining party may seek action through a court of law.
(Adopted 5/18)
Section 9.4: MLS Rules Violation
MLS participants may not take legal action against another participant for alleged rules
violation(s) unless the complaining participant has first exhausted the remedies provided in these
rules. (Adopted 5/18)
Note: Adoption of Sections 9.3 and 9.4 are not required if the MLS has adopted alternative
procedures to address alleged misuse of listing content that includes notice to the alleged
infringer.
Confidentiality of MLS Information
Section 10: Confidentiality of MLS Information
Any information provided by the multiple listing service to the participants shall be considered
official information of the service. Such information shall be considered confidential and
exclusively for the use of participants and real estate licensees affiliated with such participants
and those participants who are licensed or certified by an appropriate state regulatory agency to
engage in the appraisal of real property and licensed or certified appraisers affiliated with such
participants. (Amended 4/92)
Section 10.1 MLS Not Responsible for Accuracy of Information
The information published and disseminated by the service is communicated verbatim, without
change by the service, as filed with the service by the participant. The service does not verify
such information provided and disclaims any responsibility for its accuracy. Each participant
agrees to hold the service harmless against any liability arising from any inaccuracy or
inadequacy of the information such participant provides.
Ownership of MLS Compilation* and Copyright
*The term MLS compilation, as used in Sections 11 and 12 herein, shall be construed to include
any format in which property listing data is collected and disseminated to the participants,
including but not limited to bound book, loose-leaf binder, computer database, card file, or any
other format whatsoever.
Section 11
By the act of submitting any property listing content to the MLS, the participant represents and
warrants that he or she is fully authorized to license the property listing content as contemplated
by and in compliance with this section and these rules and regulations, and also thereby does
grant to the MLS license to include the property listing content in its copyrighted MLS
compilation and also in any statistical report on comparables. Listing content includes, but is not
limited to, photographs, images, graphics, audio and video recordings, virtual tours, drawings,
descriptions, remarks, narratives, pricing information, and other details or information related to
the listed property. (Amended 5/18)
Each participant who submits listing content to the MLS agrees to defend and hold the MLS and
every other participant harmless from and against any liability or claim arising from any
inaccuracy of the submitted listing content or any inadequacy of ownership, license, or title to
the submitted listing content. (Adopted 5/18)
Note: The Digital Millennium Copyright Act (DMCA) is a federal copyright law that enhances
the penalties for copyright infringement occurring on the Internet. The law provides exemptions
or “safe harbors” from copyright infringement liability for online service providers (OSP) that
satisfy certain criteria. Courts construe the definition of “online service provider” broadly, which
would likely include MLSs as well as participants and subscribers hosting an IDX display.
One safe harbor limits the liability of an OSP that hosts a system, network or website on which
Internet users may post user-generated content. If an OSP complies with the provisions of this
DMCA safe harbor, it cannot be liable for copyright infringement if a user posts infringing
material on its website. This protects an OSP from incurring significant sums in copyright
infringement damages, as statutory damages are as high as $150,000 per work. For this reason, it
is highly recommended that MLSs, participants and subscribers comply with the DMCA safe
harbor provisions discussed herein.
To qualify for this safe harbor, the OSP must:
1. Designate on its website and register with the Copyright Office an agent to receive
takedown requests. The agent could be the MLS, participant, subscriber, or other individual
or entity.
2. Develop and post a DMCA-compliant website policy that addresses repeat offenders.
3. Comply with the DMCA takedown procedure. If a copyright owner submits a takedown
notice to the OSP, which alleges infringement of its copyright at a certain location, then the
OSP must promptly remove allegedly infringing material. The alleged infringer may submit
a counter-notice that the OSP must share with the copyright owner. If the copyright owner
fails to initiate a copyright lawsuit within ten (10) days, then the OSP may restore the
removed material.
4. Have no actual knowledge of any complained-of infringing activity.
5. Not be aware of facts or circumstances from which complained-of infringing activity is
apparent.
6. Not receive a financial benefit attributable to complained-of infringing activity when the
OSP is capable of controlling such activity.
Full compliance with these DMCA safe harbor criteria will mitigate an OSP’s copyright
infringement liability. For more information see 17 U.S.C. §512. (Adopted 11/15)
Section 11.1
All right, title, and interest in each copy of every multiple listing compilation created and
copyrighted by the Iowa Association of REALTORS® and in the copyrights therein, shall at all
times remain vested in the Iowa Association of REALTORS®.
Section 11.2: Display
Each participant shall be entitled to lease from the Iowa Association of REALTORS® a number
of copies of each MLS compilation sufficient to provide the participant and each person
affiliated as a licensee (including licensed or certified appraisers) with such participant with one
copy of such compilation. The participant shall pay for each such copy the rental fee set by the
association.*
Participants shall acquire by such lease only the right to use the MLS compilation in accordance
with these rules.
Use of Copyrighted MLS Compilation
Section 12: Distribution
Participants shall, at all times, maintain control over and responsibility for each copy of any
MLS compilation leased to them by the association of REALTORS®, and shall not distribute
any such copies to persons other than subscribers who are affiliated with such participant as
licensees, those individuals who are licensed or certified by an appropriate state regulatory
agency to engage in the appraisal of real property, and any other subscribers as authorized
pursuant to the governing documents of the MLS. Use of information developed by or published
by an association multiple listing service is strictly limited to the activities authorized under a
participant’s licensure(s) or certification, and unauthorized uses are prohibited. Further, none of
the foregoing is intended to convey participation or membership or any right of access to
information developed or published by an association multiple listing service where access to
such information is prohibited by law. (Amended 4/92)
Section 12.1: Display
Participants and those persons affiliated as licensees with such participants shall be permitted to
display the MLS compilation to prospective purchasers only in conjunction with their ordinary
business activities of attempting to locate ready, willing, and able buyers for the properties
described in said MLS compilation.
Section 12.2: Reproduction
Participants or their affiliated licensees shall not reproduce any MLS compilation or any portion
thereof, except in the following limited circumstances:
Participants or their affiliated licensees may reproduce from the MLS compilation and distribute
to prospective purchasers a reasonable* number of single copies of property listing data
contained in the MLS compilation which relate to any properties in which the prospective
purchasers are or may, in the judgment of the participants or their affiliated licensees, be
interested.
Nothing contained herein shall be construed to preclude any participant from utilizing,
displaying, distributing, or reproducing property listing sheets or other compilations of data
pertaining exclusively to properties currently listed for sale with the participant.
Any MLS information, whether provided in written or printed form, provided electronically, or
provided in any other form or format, is provided for the exclusive use of the participant and
those licensees affiliated with the participant who are authorized to have access to such
information. Such information may not be transmitted, retransmitted, or provided in any manner
to any unauthorized individual, office, or firm.
None of the foregoing shall be construed to prevent any individual legitimately in possession of
current listing information, sold information, comparables, or statistical information from
utilizing such information to support valuations on particular properties for clients and
customers. Any MLS content in data feeds available to participants for real estate brokerage
purposes must also be available to participants for valuation purposes, including automated
valuations. MLSs must either permit use of existing data feeds, or create a separate data feed, to
satisfy this requirement. MLSs may require execution of a third-party license agreement where
deemed appropriate by the MLS. MLSs may require participants who will use such data feeds to
pay the reasonably estimated costs incurred by the MLS in adding or enhancing its downloading
capacity for this purpose. Information deemed confidential may not be used as supporting
documentation. Any other use of such information is unauthorized and prohibited by these rules
and regulations. (Amended 05/14)
Use of MLS Information
Section 13: Limitations on Use of MLS Information
Information from MLS compilations of current listing information, from statistical reports, and
from any sold or comparable report of the association or MLS may be used by MLS participants
as the basis for aggregated demonstrations of market share or comparisons of firms in public
mass-media advertising or in other public representations. This authority does not convey the
right to include in any such advertising or representation information about specific properties
which are listed with other participants, or which were sold by other participants (as either listing
or cooperating broker).
However, any print or non-print forms of advertising or other forms of public representations
based in whole or in part on information supplied by the association or its MLS must clearly
demonstrate the period of time over which such claims are based and must include the following,
or substantially similar, notice:
Based on information from the Iowa Association of REALTORS® (alternatively, from the
_____ MLS) for the period (date) through (date). (Adopted 11/97)
Changes in Rules and Regulations
Section 14: Changes in Rules and Regulations
Amendments to the rules and regulations of the service shall be by a majority vote of the
members of the multiple listing service committee, subject to approval by the board of directors
of the association of REALTORS®.
Note: Some associations may prefer to change the rules and regulations by a vote of the
participants, subject to approval by the board of directors of the association of REALTORS®.
Orientation
Section 15: Orientation
Any applicant for MLS participation and any licensee (including licensed or certified appraisers)
affiliated with an MLS participant who has access to and use of MLS-generated information
shall complete an orientation program of no more than eight (8) classroom hours devoted to the
MLS rules and regulations and computer training related to MLS information entry and retrieval
and the operation of the MLS within thirty (30) days after access has been provided. (Amended
11/04)
Participants and subscribers may be required, at the discretion of the MLS, to complete
additional training of not more than four (4) classroom hours in any twelve (12) month period
when deemed necessary by the MLS to familiarize participants and subscribers with system
changes or enhancements and/or changes to MLS rules or policies. Participants and subscribers
must be given the opportunity to complete any mandated orientation and additional training
remotely. (Amended11/17)
Internet Data Exchange (IDX)
Section 16: IDX Defined
IDX affords MLS participants the ability to authorize limited electronic display and delivery of
their listings by other participants via the following authorized mediums under the participant’s
control: websites, mobile apps, and audio devices. As used throughout these rules, “display”
includes “delivery” of such listing. (Amended 5/17)
Section 16.1: Authorization
Participants’ consent for display of their listings by other participants pursuant to these rules and
regulations is presumed unless a participant affirmatively notifies the MLS that the participant
refuses to permit display (either on a blanket or on a listing-by-listing basis). If a participant
refuses on a blanket basis to permit the display of that participant’s listings, that participant may
not download, frame or display the aggregated MLS data of other participants.*
Section 16.2: Participation
Option #3: Participation in IDX is available to all MLS participants engaged in real estate
brokerage who consent to display of their listings by other participants. (Amended 11/09)
Section 16.2.1
Participants must notify the MLS of their intention to display IDX information and must give the
MLS direct access for purposes of monitoring/ensuring compliance with applicable rules and
policies. (Amended 05/12).
Section 16.2.2
MLS participants may not use IDX-provided listings for any purpose other than display as
provided for in these rules. This does not require participants to prevent indexing of IDX listings
by recognized search engines. (Amended 05/12)
Section 16.2.3
Listings, including property addresses, can be included in IDX displays except where a seller has
directed their listing broker to withhold their listing or the listing’s property address from all
display on the Internet (including, but not limited to, publicly-accessible websites or VOWs) or
other electronic forms of display or distribution. (Amended 05/17)
Section 16.2.4
Participants may select the listings they choose to display through IDX based only on objective
criteria including, but not limited to, factors such as geography or location (“uptown,”
“downtown,” etc.), list price, type of property (e.g., condominiums, cooperatives, single-family
detached, multi-family), or type of listing (e.g., exclusive right-to-sell or exclusive agency).
Selection of listings displayed through IDX must be independently made by each participant.
(Amended 11/21)
Section 16.2.5
Participants must refresh all MLS downloads and IDX displays automatically fed by
those downloads at least once every twelve (12) hours. (Amended 11/14)
Section 16.2.6
Except as provided in the IDX policy and these rules, an IDX site or a participant or user
operating an IDX site or displaying IDX information as otherwise permitted may not distribute,
provide, or make any portion of the MLS database available to any person or entity. (Amended
05/12)
Section 16.2.7
Any IDX display controlled by a participant must clearly identify the name of the brokerage firm
under which they operate in a readily visible color and typeface. For purposes of the IDX policy
and these rules, “control” means the ability to add, delete, modify and update information as
required by the IDX policy and MLS rules. (Amended 05/12).
Section 16.2.8
Any IDX display controlled by a participant or subscriber that
a) allows third-parties to write comments or reviews about particular listings or displays a
hyperlink to such comments or reviews in immediate conjunction with particular listings,
or
b) displays an automated estimate of the market value of the listing (or hyperlink to such
estimate) in immediate conjunction with the listing,
either or both of those features shall be disabled or discontinued for the seller’s listings at the
request of the seller. The listing broker or agent shall communicate to the MLS that the seller has
elected to have one or both of these features disabled or discontinued on all displays controlled
by participants. Except for the foregoing and subject to Section 18.2.9, a participant’s IDX
display may communicate the participant’s professional judgment concerning any listing.
Nothing shall prevent an IDX display from notifying its customers that a particular feature has
been disabled at the request of the seller. (Adopted 05/12)
Section 16.2.9
Participants shall maintain a means (e.g., e-mail address, telephone number) to receive comments
about the accuracy of any data or information that is added by or on behalf of the participant
beyond that supplied by the MLS and that relates to a specific property. Participants shall correct
or remove any false data or information relating to a specific property upon receipt of a
communication from the listing broker or listing agent for the property explaining why the data
or information is false. However, participants shall not be obligated to remove or correct any
data or information that simply reflects good faith opinion, advice, or professional judgment.
(Amended 05/12)
Section 16.2.10
An MLS participant (or where permitted locally, an MLS subscriber) may co-mingle the listings
of other brokers received in an IDX feed with listings available from other MLS IDX feeds,
provided all such displays are consistent with the IDX rules, and the MLS participant (or MLS
subscriber) holds participatory rights in those MLSs. As used in this policy, “co-mingling”
means that consumers are able to execute a single property search of multiple IDX data feeds
resulting in the display of IDX information from each of the MLSs on a single search results
page; and that participants may display listings from each IDX feed on a single webpage or
display. (Adopted 11/14)
Section 16.2.11
Participants shall not modify or manipulate information relating to other participants' listings.
MLS participants may augment their IDX display of MLS data with applicable property
information from other sources to appear on the same webpage or display, clearly separated by
the data supplied by the MLS. The source(s) of the information must be clearly identified in the
immediate proximity to such data. This requirement does not restrict the format of MLS data
display or display of fewer than all of the available listings or fewer authorized fields. (Adopted
05/15)
Section 16.2.12
All listings displayed pursuant to IDX shall identify the listing firm, and the email or phone
number provided by the listing participant in a reasonably prominent location and in a
readily visible color and typeface not smaller than the median used in the display of listing data.*
(Amended 11/21)
*Displays of minimal information (e.g., “thumbnails”, text messages, “tweets”, etc., of two
hundred [200] characters or less) are exempt from this requirement but only when linked
directly to a display that includes all required disclosures. For audio delivery of listing content,
all required disclosures must be subsequently delivered electronically to the registered consumer
performing the property search or linked to through the device’s application. (Amended 5/17)
Section 16.3: Display
Display of listing information pursuant to IDX is subject to the following rules:
Section 16.3.1
Listings displayed pursuant to IDX shall contain only those fields of data designated by the
MLS. Display of all other fields (as determined by the MLS) is prohibited. Confidential
fields intended only for other MLS participants and users (e.g., showing instructions, and
property security information) may not be displayed. (Amended 11/21)
Section 16.3.2
All listings displayed pursuant to IDX shall identify the listing agent.
Section 16.3.3
Non-principal brokers and sales licensees affiliated with IDX participants may display
information available through IDX on their own websites subject to their participant’s consent
and control and the requirements of state law and/or regulation.
Section 16.3.4
All listings displayed pursuant to IDX shall show the MLS as the source of the information.
(Amended 05/17)
Section 16.3.5
Participants (and their affiliated licensees, if applicable) shall indicate on their websites that IDX
information is provided exclusively for consumers’ personal, noncommercial use, that it may not
be used for any purpose other than to identify prospective properties consumers may be
interested in purchasing, and that the data is deemed reliable but is not guaranteed accurate by
the MLS. The MLS may, at its discretion, require use of other disclaimers as necessary to protect
participants and/or the MLS from liability.* (Amended 05/17)
*Displays of minimal information (e.g., “thumbnails”, text messages, “tweets”, etc., of two
hundred [200] characters or less) are exempt from this requirement but only when linked
directly to a display that includes all required disclosures. For audio delivery of listing content,
all required disclosures must be subsequently delivered electronically to the registered consumer
performing the property search or linked to through the device’s application. (Amended 05/17)
Section 16.3.6
The data consumers can retrieve or download in response to an inquiry shall be determined by
the MLS but in no instance shall be limited to fewer than five hundred (500) listings or fifty
percent (50%) of the listings available for IDX display, whichever is fewer. (Amended 11/17)
Section 16.3.7
The right to display other participants’ listings pursuant to IDX shall be limited to a participant’s
office(s) holding participatory rights in this MLS.
Section 16.3.8
Listings obtained through IDX feeds from Realtor® Association MLSs where the MLS
participant holds participatory rights must be displayed separately from listings obtained from
other sources. Listings obtained from other sources (e.g., from other MLSs, from non-
participating brokers, etc.) must display the source from which each such listing was obtained.*
(Amended 05/17)
Note: An MLS participant (or where permitted locally, an MLS subscriber) may co-mingle the
listings of other brokers received in an IDX feed with listings available from other MLS IDX
feeds, provided all such displays are consistent with the IDX rules, and the MLS participant (or
MLS subscriber) holds participatory rights in those MLSs. As used in this policy, “co-mingling”
means that consumers are able to execute a single property search of multiple IDX data feeds
resulting in the display of IDX information from each of the MLSs on a single search results
page; and that participants may display listings from each IDX feed on a single webpage or
display. (Adopted 11/14)
*Displays of minimal information (e.g., “thumbnails”, text messages, “tweets”, etc., of two
hundred [200] characters or less) are exempt from this requirement but only when linked
directly to a display that includes all required disclosures. For audio delivery of listing content,
all required disclosures must be subsequently delivered electronically to the registered consumer
performing the property search or linked to through the device’s application. (Amended 05/17)
Section 16.3.9Display of expired, withdrawn, and sold listings** is prohibited. (Amended
11/15)
**Note: If “sold” information is publicly accessible, display of “sold” listings may not be
prohibited. (Adopted 11/14)
Section 16.3.10
Display of seller’s(s’) and/or occupant’s(s’) name(s), phone number(s), and e-mail address(es) is
prohibited.
Note: The following Sections 18.3.14 and 18.3.15 may be adopted by MLSs that provide
participants with a “persistent” download (i.e., where the MLS database resides on participants’
servers) of the MLS database.
Section 16.3.11
Participants are required to employ appropriate security protection such as firewalls on their
websites and displays, provided that any security measures required may not be greater than
those employed by the MLS. (Amended 05/12)
Section 16.3.12
Deceptive or misleading advertising (including co-branding) on pages displaying IDX-provided
listings is prohibited. For purposes of these rules, co-branding will be presumed not to be
deceptive or misleading if the participant’s logo and contact information is larger than that of any
third party.
(Adopted 11/09)
Section 16.3.13 (only highlighted because new 2022 rule)
Display of expired, and withdrawn listings is prohibited. (Amended 05/21)
**Note: If “sold” information is publicly accessible, display of “sold” listings may not be
prohibited. (Adopted 11/14)
Section 17: Virtual Office Websites (VOWs)
Section 17.1 VOW Defined
a) A “Virtual Office Website” (VOW) is a participant’s Internet website, or a feature of a
participant’s website, through which the participant is capable of providing real estate
brokerage services to consumers with whom the participant has first established a broker-
consumer relationship (as defined by state law) where the consumer has the opportunity to
search MLS listing information, subject to the participant’s oversight, supervision, and
accountability. A non-principal broker or sales licensee affiliated with a participant may,
with his or her participant’s consent, operate a VOW. Any VOW of a non-principal broker
or sales licensee is subject to the participant’s oversight, supervision, and accountability.
b) As used in Section 19 of these rules, the term “participant” includes a participant’s
affiliated non-principal brokers and sales licenseesexcept when the term is used in the
phrases “participant’s consent” and “participant’s oversight, supervision, and
accountability”. References to “VOW” and “VOWs” include all Virtual Office Websites,
whether operated by a participant, by a non-principal broker or sales licensee, or by an
“Affiliated VOW Partner” (AVP) on behalf of a participant.
c) "Affiliated VOW Partner” (AVP) refers to an entity or person designated by a
participant to operate a VOW on behalf of the participant, subject to the participant’s
supervision, accountability, and compliance with the VOW policy. No AVP has
independent participation rights in the MLS by virtue of its right to receive information on
behalf of a participant. No AVP has the right to use MLS listing information, except in
connection with operation of a VOW on behalf of one or more participants. Access by an
AVP to MLS listing information is derivative of the rights of the participant on whose
behalf the AVP operates a VOW. As used in Section 19 of these rules, the term “MLS
listing information” refers to active listing information and sold data provided by
participants to the MLS and aggregated and distributed by the MLS to participants.
Section 17.2
a) The right of a participant’s VOW to display MLS listing information is limited to that
supplied by the MLS(s) in which the participant has participatory rights. However, a
participant with offices participating in different MLSs may operate a master website with
links to the VOWs of the other offices.
b) Subject to the provisions of the VOW policy and these rules, a participant’s VOW,
including any VOW operated on behalf of a participant by an AVP, may provide other
features, information, or functions, e.g., “Internet Data Exchange” (IDX).
c) Except as otherwise provided in the VOW policy or in these rules, a participant need not
obtain separate permission from other MLS participants whose listings will be displayed
on the participant’s VOW.
Section 17.3
a) Before permitting any consumer to search for or retrieve any MLS listing information
on his or her VOW, the participant must take each of the following steps.
i. The participant must first establish with that consumer a lawful broker-consumer
relationship (as defined by state law), including completion of all actions required
by state law in connection with providing real estate brokerage services to clients
and customers (hereinafter, “Registrants”). Such actions shall include, but are not
limited to, satisfying all applicable agency, non-agency, and other disclosure
obligations, and execution of any required agreements.
ii. The participant must obtain the name of and a valid e-mail address for each
Registrant. The participant must send an e-mail to the address provided by the
Registrant confirming that the Registrant has agreed to the terms of use (described in
Subsection d., below). The participant must verify that the e-mail address provided
by the Registrant is valid and that the Registrant has agreed to the terms of use.
iii. The participant must require each Registrant to have a user name and a password,
the combination of which is different from those of all other Registrants on the
VOW. The participant may, at his or her option, supply the user name and password
or may allow the Registrant to establish its user name and password. The participant
must also assure that any e-mail address is associated with only one user name and
password.
b) The participant must assure that each Registrant’s password expires on a date certain,
but may provide for renewal of the password. The participant must at all times maintain a
record of the name, e-mail address, user name, and current password of each Registrant.
The participant must keep such records for not less than one hundred eighty (180) days
after the expiration of the validity of the Registrant’s password.
c) If the MLS has reason to believe that a participant’s VOW has caused or permitted a
breach in the security of MLS listing information or a violation of MLS rules, the
participant shall, upon request of the MLS, provide the name, e-mail address, user name,
and current password, of any Registrant suspected of involvement in the breach or
violation. The participant shall also, if requested by the MLS, provide an audit trail of
activity by any such Registrant.
d) The participant shall require each Registrant to review and affirmatively to express
agreement (by mouse click or otherwise) to a terms of use provision that provides at least
the following:
i. that the Registrant acknowledges entering into a lawful consumer-broker
relationship with the participant
ii. that all information obtained by the Registrant from the VOW is intended only for
the Registrant’s personal, non-commercial use
iii. that the Registrant has a bona fide interest in the purchase, sale, or lease of real
estate of the type being offered through the VOW
iv. that the Registrant will not copy, redistribute, or retransmit any of the
information provided, except in connection with the Registrant’s consideration of
the purchase or sale of an individual property
v. that the Registrant acknowledges the MLS’ ownership of and the validity of the
MLS’ copyright in the MLS database
e) The terms of use agreement may not impose a financial obligation on the Registrant or
create any representation agreement between the Registrant and the participant. Any
agreement entered into at any time between the participant and Registrant imposing a
financial obligation on the Registrant or creating representation of the Registrant by the
participant must be established separately from the terms of use, must be prominently
labeled as such, and may not be accepted solely by mouse click.
f) The terms of use agreement shall also expressly authorize the MLS and other MLS
participants or their duly authorized representatives to access the VOW for the purposes of
verifying compliance with MLS rules and monitoring display of participants’ listings by
the VOW. The agreement may also include such other provisions as may be agreed to
between the participant and the Registrant.
Section 17.4
A participant’s VOW must prominently display an e-mail address, telephone number, or specific
identification of another mode of communication (e.g., live chat) by which a consumer can
contact the participant to ask questions or get more information about any property displayed on
the VOW. The participant or a non-principal broker or sales licensee licensed with the
participant must be willing and able to respond knowledgeably to inquiries from Registrants
about properties within the market area served by that participant and displayed on the VOW.
Section 17.5
A participant’s VOW must employ reasonable efforts to monitor for and prevent
misappropriation, scraping, and other unauthorized uses of MLS listing information. A
participant’s VOW shall utilize appropriate security protection such as firewalls as long as this
requirement does not impose security obligations greater than those employed concurrently by
the MLS.
Note: MLSs may adopt rules requiring Participants to employ specific security measures,
provided that any security measure required does not impose obligations greater than those
employed by the MLS.
Section 17.6
a) A participant’s VOW shall not display the listings or property addresses of any seller
who has affirmatively directed the listing broker to withhold the seller’s listing or property
address from display on the Internet. The listing broker shall communicate to the MLS that
the seller has elected not to permit display of the listing or property address on the Internet.
Notwithstanding the foregoing, a participant who operates a VOW may provide to
consumers via other delivery mechanisms, such as e-mail, fax, or otherwise, the listings of
sellers who have determined not to have the listing for their property displayed on the
Internet.
b) A participant who lists a property for a seller who has elected not to have the property
listing or the property address displayed on the Internet shall cause the seller to execute a
document that includes the following (or a substantially similar) provision.
c) The participant shall retain such forms for at least one (1) year from the date they are
signed or one (1) year from the date the listing goes off the market, whichever is greater.

i. to write comments or reviews about particular listings or display a hyperlink to
such comments or reviews in immediate conjunction with particular listings, or
ii. to display an automated estimate of the market value of the listing (or hyperlink to
such estimate) in immediate conjunction with the listing.
b) Notwithstanding the foregoing, at the request of a seller, the participant shall disable or
discontinue either or both of those features described in Subsection a. as to any listing of
the seller. The listing broker or agent shall communicate to the MLS that the seller has
elected to have one or both of these features disabled or discontinued on all participants’
websites. Subject to the foregoing and to Section 19.8, a participant’s VOW may
communicate the participant’s professional judgment concerning any listing. A
participant’s VOW may notify its customers that a particular feature has been disabled at
the request of the seller.
Section 17.8
A participant’s VOW shall maintain a means (e.g., e-mail address, telephone number) to receive
comments from the listing broker about the accuracy of any information that is added by or on
behalf of the participant beyond that supplied by the MLS and that relates to a specific property
displayed on the VOW. The participant shall correct or remove any false information relating to
a specific property within forty-eight (48) hours following receipt of a communication from the
listing broker explaining why the data or information is false. The participant shall not, however,
be obligated to correct or remove any data or information that simply reflects good faith opinion,
advice, or professional judgment.

A participant shall cause the MLS listing information available on its VOW to be refreshed at
least once every three (3) days.

of the ways in which information that they provide may be used.
Section 17.12
A participant’s VOW may exclude listings from display based only on objective criteria,
including, but not limited to, factors such as geography, list price, type of property, cooperative
compensation offered by listing broker, and whether the listing broker is a REALTOR®.
Section 17.13
A participant who intends to operate a VOW to display MLS listing information must notify the
MLS of its intention to establish a VOW and must make the VOW readily accessible to the MLS
and to all MLS participants for purposes of verifying compliance with these rules, the VOW
policy, and any other applicable MLS rules or policies.
Section 17.14
A participant may operate more than one VOW himself or herself or through an AVP. A
participant who operates his or her own VOW may contract with an AVP to have the AVP
operate other VOWs on his or her behalf. However, any VOW operated on behalf of a
participant by an AVP is subject to the supervision and accountability of the participant.
Note: Adoption of Sections 19.15 through 19.19 is at the discretion of the MLS. However, if any
of the following sections are adopted, an equivalent requirement must be imposed on
participants’ use of MLS listing information in providing brokerage service through all other
delivery mechanisms.
Section 17.15
A participant’s VOW may not make available for search by or display to Registrants any of the
following information:
a) expired and withdrawn listings
Note: Due to the 2015 changes in IDX policy and the requirement that participants
be permitted to make MLS listing information available to Registrants of VOW sites
where such information may be made available via other delivery mechanisms,
MLSs can no longer prohibit the display of pending (“under contract”) listings on
VOW sites.
b) the compensation offered to other MLS participants
c) the type of listing agreement, i.e., exclusive right-to-sell or exclusive agency
d) the seller’s and occupant’s name(s), phone number(s), or e-mail address(es)

showings or security of listed property
Section 17.16
A participant shall not change the content of any MLS listing information that is displayed on a
VOW from the content as it is provided in the MLS. The participant may, however, augment
MLS listing information with additional information not otherwise prohibited by these rules or
by other applicable MLS rules or policies, as long as the source of such other information is
clearly identified. This rule does not restrict the format of display of MLS listing information on
VOWs or the display on VOWs of fewer than all of the listings or fewer than all of the
authorized information fields.
Section 17.17
A participant shall cause to be placed on his or her VOW a notice indicating that the MLS listing
information displayed on the VOW is deemed reliable, but is not guaranteed accurate by the
MLS. A participant’s VOW may include other appropriate disclaimers necessary to protect the
participant and/or the MLS from liability.
Section 17.18 (only highlighted due to new 2022 rule)
A participant shall cause any listing that is displayed on his or her VOW to identify the name of
the listing firm, the listing broker or agent, and the email or phone number provided by the

participant’s logo and contact information (or that of at least one participant, in the case of a
VOW established and operated on behalf of more than one participant) is displayed in immediate
conjunction with that of every other party, and the logo and contact information of all
participants displayed on the VOW is as large as the logo of the AVP and larger than that of any
third party.
Section 17.22
A participant shall cause any listing displayed on his or her VOW obtained from other sources,
including from another MLS or from a broker not participating in the MLS, to identify the source
of the listing.
Section 17.23
