Compass Inc., the top US broker for residential properties, sued California’s largest real estate listing service, CRMLS, in federal court in Los Angeles, alleging anticompetitive rules that require agents to list homes within one business day or face fines. Compass claims the rule violates US antitrust laws and unfairly limits competition by forcing public disclosure of listings before agents can market them privately. The suit escalates a broader legal fight over access to home sale information, with Compass arguing homeowners should be free to choose how to sell their homes without industry-imposed restrictions.
CRMLS, covering 22 counties including Los Angeles, the San Francisco Bay Area, and San Diego, said it would “vigorously defend” its rules, stating they support fair competition, preserve seller choice, and prevent brokerages from gaining unfair advantages by using the shared database without contributing. CRMLS had previously sued Compass in New York federal court, alleging the company wanted to advertise homes on its own platform while withholding them from the shared MLS database. Compass defends its three-phased marketing strategy—internal broker marketing, then “coming soon” on its website—claiming it leads to higher sales prices and more options for sellers.
The dispute reflects ongoing tensions between private listing networks and traditional MLS systems, with Zillow and other platforms relying on MLS data. Similar legal battles have occurred with Zillow and Midwest Real Estate Data in Chicago.
