California State ADU Standards
These are the guaranteed rights for homeowners in San Francisco under California State Law. Local agencies cannot enforce stricter standards than these baselines.
State law prohibits local agencies from setting limits below 850 sq. ft. (1 bd) or 1,000 sq. ft. (2 bd). Generally, up to 1,200 sq. ft. is allowed subject to setbacks.
Local agencies cannot require rear or side setbacks of more than 4 feet.
Minimum allowed height limit. Some areas allow up to 18-25ft depending on proximity to transit or main house.
No parking required if ADU is within 1/2 mile of public transit, historic district, or part of existing home footprint.
State law currently prohibits owner-occupancy requirements for ADUs permitted between 2020 and 2025.
Development impact fees are waived for ADUs smaller than 750 sq. ft. For larger units, fees must be proportional.
* While these state laws provide a baseline, always verify specific local overlay zones or fire safety regulations with the San Francisco planning department.
