All capitalized terms carry the same definitions given in the MLS GRID IDX Master Data License
IDX or Broker Reciprocity is defined as a cooperative program where the Member Participant grants permission to display their listings on the websites of other Member Participants, and receives the same permissions in return. The use of MLS GRID Data for IDX grants 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 listings. Electronic display subject to these IDX Rules means displays on public websites and displays using applications for mobile devices that the Member Participant controls. In order to use MLS GRID Data a Member Participant must be actively engaged in listing properties for sale and/or assisting and negotiating on behalf of buyers or sellers in real estate transactions.
The Member Participant’s consent for display of their listings by other Member Participants may be presumed unless a Member Participant affirmatively notifies MLS GRID or their MLS that they refuse to permit display on a listing-by-listing basis or a Member Participant affirmatively notifies MLS GRID or their MLS that they refuse to permit display on a blanket basis. An MLS may require a Member Participant to affirmatively Opt-In their listings on a listing-by-listing basis to consent for display of their listings by other Member Participants. Any Member Participant may at any time, by written notice to MLS GRID, request that no data from their listings be included in MLS GRID Data for IDX and an IDX Opt-Out Form may be required. Within ten (10) Business Days after receipt of such notice, MLS GRID shall discontinue including any data from the Member Participant’s listings in the MLS GRID Data for IDX.
Participation in IDX is available to all Member Participants who are authorized by their applicable MLS’s Governing Documents and who consent to the display of their listings by other Member Participants.
Each Member Participant must notify MLS GRID or their applicable MLS of their intention to establish a website, an application, or provide services involving the use and/or display of MLS GRID Data, and must give MLS GRID direct access for purposes of monitoring and ensuring compliance with applicable policies and license agreements, including these IDX Rules.
Member Participants may not use IDX provided listings for any purpose other than display as provided for in these IDX Rules. This does not require the Member Participant to prevent indexing of listings by recognized search engines.
Any IDX display must be under the actual and apparent control of a single Member Participant who has executed a MLS GRID IDX Master Data License Agreement. Actual control means that the Member Participant has either built the website for their own use with internal resources, or obtained technology for the website under an agreement with a Vendor that provides the Member Participant final control over the operations of the website. Additionally, “actual control” means the ability to add, delete, modify and update information as required by MLS GRID and their applicable MLS’s Governing Documents. Apparent control means that a reasonable consumer viewing the website would conclude that it is under the control of the Member Participant. The following are currently conclusively deemed to be evidence of apparent control: that the Member Participant’s branding is equal to or more prominent than that of any other entity, and that the domain name and branding on the website distinguish the Member Participant from non-participating firms, e.g., from other franchisees of the same franchise, if applicable.
Listings, including property addresses, can be included in displays of MLS GRID Data except where a seller has directed their Member Participant to withhold their listing or the listing’s property address from all public display on the Internet (including, but not limited to, display on publicly-accessible websites or VOWs or on maps) or other electronic forms of display or distribution.
A Member 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 or other electronic forms of display or distribution shall cause the seller to execute a document that includes such a provision, in accordance with their applicable MLS Governing Documents.
Member Participants may select the listings they choose to display through IDX based solely on objective criteria, including but not limited to factors such as geography or location, list price, type of property, , or type of listing. Selection of listings displayed through IDX must be independently made by each Member Participant. If the Member Participant chooses to limit the display of any listings based on objective criteria, the Member Participant’s IDX site must include a disclosure to consumers that clearly states “Some IDX listings have been excluded from this website.”
“Thumbnail” refers to a summary of listing information containing no more than eight selection criteria describing the property (e.g. List Price, MLS Number, Address, Beds, Baths, SqFt., Status, and Subdivision). Any search result identifying another Member Participant’s listing in a thumbnail format may not include contact information or branding of the Member Participant’s IDX site, or brokerage.
Each Member Participant must refresh all MLS GRID Data downloads and IDX displays automatically fed by those downloads at least once every twelve (12) hours to include new data and exclude data that has been removed from the MLS GRID Data.
Sharing of the MLS GRID Data compilation with any third party not authorized by MLS GRID is prohibited.
All IDX displays must be under the actual and apparent control of a Member Participant and must clearly identify the name of the brokerage firm under which the Member Participant operates in a readily visible color and typeface. Displays of minimum information (e.g. a one-line or ”thumbnail,” 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.
Any IDX display controlled by a Member Participant 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, shall disable or discontinue either or both of those features as to the seller’s listing 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 the Member Participant. Except for the foregoing and subject to the section below, a Member Participant’s IDX display may communicate the Member Participant’s professional judgment concerning any listing. Nothing shall prevent an IDX display from notifying its viewers that a particular feature has been disabled at the request of the seller.
Member Participant 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 Member Participant beyond that supplied by MLS GRID and that relates to a specific property. Member Participant shall correct or remove any false data or information relating to a specific property upon receipt of a communication from the listing Member Participant for the property explaining why the data or information is false. However, Member Participant shall not be obligated to remove or correct any data or information that simply reflects good faith opinion, advice, or professional judgment of the Member Participant controlling the IDX display.
Member Participant may co-mingle listings through IDX provided by MLS GRID with listings from other MLS sources on its IDX display, provided all such displays are consistent with these IDX Rules. Co-mingling is (a) the ability for a visitor to the website to execute a single search that searches any portion of MLS GRID Data for IDX display at the same time it searches listing data from any other source(s); or (b) the display on a single web page of any portion of MLS GRID Data for IDX display and listing data from any other source. Listings obtained from non-MLS GRID MLSs must display the source from which each such listing was obtained. Displays of minimum information (e.g. a one-line or “thumbnail,” 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.
In the event of any default by the Member Participant, or the occurrence of any event which MLS GRID believes may constitute an event of default by the Vendor under these IDX Rules, including any violation of or noncompliance with the MLS GRID IDX Master Data License Agreement, or failure by the Member Participant to pay any fees or fines owing to MLS GRID, MLS GRID may at its option and without prior notice to the Member Participant, and in its sole discretion temporarily suspend, or terminate, the license granted to Member Participant to access the MLS GRID Data until all outstanding fees have been paid in full or the default has been cured.
No display or use of the listings, or any portion of the listings, shall be used in connection with sending unsolicited or unauthorized advertising, spam, promotional materials, or any other form of unsolicited message, whether commercial or otherwise.
Listings displayed pursuant to IDX shall contain only those fields of data designated by MLS GRID. Display of confidential fields intended only for other Member Participants is prohibited. Confidential fields intended only for other Member Participants (e.g. showing instructions, and property security information) may not be displayed. Fields may be designated as confidential at the discretion of the applicable MLS. Vendors may request a comprehensive list of confidential fields from the MLS Grid for each MLS.
The type of listing agreement (e.g., exclusive right to sell, exclusive agency, etc.) may not be displayed.
No MLS GRID Data made available to a Member Participant for IDX display shall be modified by such Member Participant; except that the display of IDX listings or other data may be augmented with additional data not otherwise prohibited from display so long as the source of the other data is clearly identified. This requirement does not restrict the modification of the listing using RESO-approved synonyms for normalization purposes. This requirement does not restrict the format of the display of the IDX listings or display of fewer than all of the IDX listings or display of fewer than the authorized data fields.
With the display of any IDX listings, all listings displayed pursuant to IDX shall identify the listing brokerage name, the listing number, and the status of the listing immediately adjacent to the property information. When displaying a sold listing, the name of the cooperating brokerage OR the following disclaimer must also appear: “Properties displayed may be listed or sold by various participants in the MLS,” as established by the applicable MLS Governing Documents. With the display of IDX Listings from Northwest MLS, all listings displayed pursuant to IDX shall identify the listing brokerage name, the listing number, and the status of the listing immediately adjacent to the primary photo or group of prominent photos. Required items must be displayed in a readily visible color and typeface not smaller than the median used in the display of listing data. For example, no tiny text or gray text displayed on a gray background. 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.
The display of any IDX listings shall clearly and conspicuously identify the providing MLS as the source of the IDX listings as distributed by the MLS GRID (e.g., “Listings courtesy of APPLICABLE MLS as distributed by MLS GRID”) in accordance with these IDX Rules. MLS GRID approved icons or logos identifying MLS GRID as the source of IDX listings must appear on the first page where any listings are displayed. Displays of minimal information (e.g. “thumbnails”, text messages, “tweets”, etc., or 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.
Member Participants (and their affiliated licensees, if applicable) shall indicate on their websites that IDX information is provided exclusively for consumers’ personal non-commercial use, that it may not be used for any purpose other than to identify prospective properties consumers may be interested in purchasing, that the data is deemed reliable but is not guaranteed by MLS GRID, and that the use of the MLS GRID Data may be subject to an end user license agreement prescribed by the Member Participant’s applicable MLS if any and as amended from time to time. MLS GRID may, at its discretion, require use of other disclaimers as necessary to protect Member Participant, and/or their MLS from liability. Each display or use of the IDX Listings, or any portion of the IDX Listings shall include the conspicuous display of the following: “Based on information submitted to the MLS GRID as of _____ (date and time MLS GRID Data was obtained). All data is obtained from various sources and may not have been verified by broker or MLS GRID. Supplied Open House Information is subject to change without notice. All information should be independently reviewed and verified for accuracy. Properties may or may not be listed by the office/agent presenting the information.” 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.
With a map display on an IDX website showing the locations of the listings matching a consumer’s search with icons or pins, where a consumer may display a “pop-up” or “balloon” over the icon or pin by clicking or holding the mouse over it, required elements need not be displayed provided that (a) the consumer can click on the pop-up or balloon and view a page, including the listing information and the required elements; or (b) there is a display elsewhere on the page on which the map appears that includes the listing information and the required elements for all such listings on the map.
The display of any IDX listings in response to a query from a consumer shall not be limited to fewer than five hundred (500) listings or fifty percent (50%), whichever is fewer, and no more than two thousand-five hundred (2,500) listings per search. This does not apply to displays showing mapping pins and no other listing data.
Listings obtained from other sources (e.g., from non-MLS sources, from non-participating brokers, etc.) must display the source from which each such listing was obtained. Displays of minimal information (e.g., “thumbnails”, text messages, “tweets”, etc., of two hundred  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. NOTE: Member Participants may choose to co-mingle, display separately, or exclude listings obtained from other sources.
The display of expired and withdrawn listings may be prohibited by the Member Participant’s applicable Governing Documents, and may be excluded from MLS GRID Data. If expired and withdrawn listings are available in MLS GRID Data for IDX, the display of those listings is authorized, except to the extent these rules expressly state otherwise. For ACTRIS Participants only: On sold listings, Member Participants may not display the sale price or photographs other than the primary photograph as designated in the data feed.
The display of the seller’s and/or occupant’s name(s), phone number(s), and email address(es) is prohibited.
Each Member Participant is required to employ appropriate security protection such as firewalls on their websites and displays, provided that any security measures required by MLS GRID may not be greater than those employed by MLS GRID. Each Member Participant shall make reasonable efforts to avoid “scraping” of the MLS GRID Data by third parties or displaying of that data on any other website. Reasonable efforts shall include but not be limited to (a) Monitoring the website for signs that a third party is “scraping” data and (b) Prominently posting notice that any use search of data on the website, other than by a consumer looking to purchase real estate, is prohibited.
