Largest MLS

What Is the Largest MLS in the U.S.?

As of November 2018, the largest MLS in the U.S. is CRMLS, which covers large areas in southern California, the central coast, and the North Bay. CRMLS has 95,000+ members, 100,000+ active listings, and if you include its data share agreements, it has a presence in more than half of California’s counties.

CRMLS was formed in 2010 when the Multi-Regional Multiple Listing Service, a 12-association MLS based in Pomona, CA, merged with calREDD, an effort at a statewide MLS created by the California Association of Realtors. Since the merger, CRMLS has made no secret that a statewide MLS remains its vision.

The MLS formed data share agreements with CLAW, based in the Los Angeles area, and CRISNET, based in the San Fernando Valley. In 2015, it added agreements with San Diego-based Sandicor, and the Silicon Valley based MLSListings.

As recently as May 2018, the organization expanded to California’s Victor Valley, Lake Arrowhead, and Big Bear regions. Today, CRMLS is made up of 36 participating association/boards and has in place 13 data share agreements.
