AB 1033

AB 1033 is a California law that lets cities opt in to allow ADUs to be sold separately from the main house as condominiums. Where a jurisdiction has adopted it, an ADU becomes a sellable asset rather than only a rental — but it only applies in cities that have passed the local ordinance.

Always confirm your specific jurisdiction has adopted an AB 1033 program before counting on a separate sale. Most Sacramento-region cities have not yet opted in as of 2026.
