MLSs are typically categorized as regional, meaning it’s controlled by more than one shareholder or spans multiple markets, or local, meaning one shareholder operating in a single market.

Each MLS is also segmented into a variety of ownership types. Association-owned MLSs are typically owned and governed by a member-owned nonprofit Realtor association. Governance, access and policies are set by association members in an effort to advance the interests of Realtor professionals and their brokerages.

Broker-owned MLSs are owned and operated by one or more brokerages or a broker-led company, where governance and commercial decisions reflect brokerage stakeholders. These MLSs commonly adopt broker-centric rules, fee structures and board representation.

Hybrid MLSs are owned or governed through a variety of models that balance the interests of a variety of stakeholders. Joint ventures between association and brokerages, regional consortiums, independent for-profit companies and tech-owned platforms are all examples of hybrid MLSs. Governance, membership eligibility and fees vary by model.
