California ADU Law

Why California Is the Best State for ADUs

State Preemption
California preempts most local ADU restrictions. Every single-family and multi-family lot in the state can have at least one ADU under AB 2221 and SB 897.
Ministerial Approval
Permit approval must be ministerial — no discretionary review, no neighbor input, no design commissions. Cities have 60 days to approve or deny.
No Parking Requirements
ADUs within half a mile of transit or in converted garages require no additional parking spaces — statewide.
Owner Occupancy Eliminated
California eliminated owner-occupancy requirements statewide. You can rent both the main house and ADU, even as a non-resident investor.
Impact Fee Exemption
ADUs under 750 sq ft are fully exempt from impact fees and connection fees statewide. This can save $10,000–$50,000 per project.
SB 9 Two-Unit Split
SB 9 allows most single-family lots to add a second primary dwelling unit AND two ADUs — up to 4 total units on one parcel in most cities.
