In California, there's no explicit statewide limit on the number of bedrooms an ADU can have. However, the practical limit typically depends on local zoning rules, lot size, maximum allowed square footage (commonly capped at 1,200 sq ft for detached ADUs), and building code requirements. Most accessory dwelling units typically have between 1–3 bedrooms due to these size constraints, though in some areas or larger lots, a 4-bedroom ADU could be possible. It's always best to check with your city or county's local planning department to confirm what's allowed for your specific property.
California’s ADU regulations simplify construction: detached ADUs can be up to 1,200 sq ft, with an 800 sq ft minimum guaranteed regardless of bedroom count. Required setbacks are 4 feet for side/rear property lines, with typical height limits between 16-18 feet. Parking isn't required for ADUs near transit, historic districts, or converted structures. Single-family homes can add one ADU and one Junior ADU; multifamily properties can have multiple ADUs. ADUs must include full-sized kitchens and meet building codes, and local approvals must be completed within 60 days. Verify specific local guidelines, as they may vary.
In California, you generally cannot sell an ADU separately from the primary home. Accessory Dwelling Units (ADUs) are intended to remain part of the main property's parcel and typically can't be subdivided or sold independently. However, recent state legislation (such as Assembly Bill 587) has opened possibilities for selling ADUs separately under specific conditions, including certain nonprofit affordable housing developments or qualified tenancy-in-common (TIC) arrangements, but these scenarios are uncommon and subject to strict regulations. For most homeowners, an ADU remains legally tied to the primary property, contributing to overall property value but not eligible to be sold separately. Always check with your local jurisdiction for specific rules regarding subdivision or separate sale of ADUs.
