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. Because AB 1033 is opt-in rather than statewide, a Sacramento homeowner cannot assume the condominium-sale option exists — unlike the 4-foot setback or the 750-square-foot fee exemption, which apply everywhere in California by right. For now, the realistic exit for a Sacramento-region ADU is rental income and added resale value of the whole property, and an owner should treat separate-sale potential as upside only if and when their specific city adopts a local AB 1033 ordinance.
