About UnityMLS

A trade association for the profession, run by the profession.

UnityMLS is a 501(c)(6) nonprofit trade association operating a nationwide multiple listing service on open real estate data standards.

Our purpose

UnityMLS exists to give licensed real estate professionals a nationwide multiple listing service they own, govern, and can rely on. We operate as a member trade association, not a private vendor. Every operating decision — fees, features, data policy, syndication choices — is subject to member representation and public disclosure.

How we are structured

UnityMLS is organized under Section 501(c)(6) of the Internal Revenue Code as a business league. Our members are licensed real estate agents, brokers, and their affiliated firms and associations. We are governed by an elected Board of Directors, and our Bylaws, Code of Ethics, and MLS Rules and Regulations are publicly available.

See our Governance page for founding documents, board composition, and financial reporting.

What makes us different

  • No mandatory dual membership. An active real estate license is the only prerequisite.
  • No commission-structure enforcement. How you and your clients arrange compensation is your business.
  • RESO-compliant from day one. The Real Estate Standards Organization Data Dictionary and Web API are the foundation of our data model.
  • No syndication mandate. You decide which portals see your listings.
  • Transparent finances. Annual audited financials, published to members.

Sister brand

UnityMLS is affiliated with Casovio, a modern property marketing platform. The two organizations share a founder-set of design and engineering standards but operate independently.
