DMCA Information


Prohibition of Listing Modification

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.


Identifying the Listing Brokerage

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 devices application.
