West Hollywood (in Los Angeles County). In early November 2026, the West Hollywood City Council unanimously approved Ordinance No. 26-13. It creates a local municipal registry for “multi-partner domestic relationships” involving three or more consenting adults (including throuples and larger groups). Key points: • It is not legal marriage or a state-recognized domestic partnership under California or federal law. Marriage remains defined as a union of two people. • Registered partners get limited local benefits, mainly hospital/healthcare facility visitation rights, jail visitation rights (within the city’s jurisdiction), and certain tenant/housing protections (e.g., against eviction or non-renewal solely for adding a partner). • Participants must be at least 18, consent, share life’s necessities and responsibility for one another’s welfare, and not be closely related by blood (in a way that would bar marriage under California law). Non-residents can also register. • It takes effect December 2, 2026. The city previously added anti-discrimination protections based on family/relationship structure.
