The service area of multiple listing services owned and operated by associations of REALTORS® Service Area of Association is not limited to the jurisdiction of the parent association(s) of REALTORS®. Rather, associations are encouraged to establish multiple listing services that encompass natural market areas and to periodically reexamine such boundaries to ensure that they encompass the relevant market area. While associations are encouraged to work cooperatively to establish market area multiple listing services, the absence of such an agreement shall not preclude any association from establishing and maintaining a multiple listing service whose service area exceeds that of the parent association(s) jurisdiction. MLSs may not require other offices of a firm to participate in the MLS if any office of that firm participates in that MLS. (Revised 11/17)
