State law, local ordinance, HOAs, and tenancy

Legal in LA

The legal framework for an LA ADU — California's preemptive ADU statute, LAMC implementation, HOA limits, and the rent-control questions every owner should ask before tenanting.

State statute
Gov. Code §65852.2
LA local ordinance
LAMC §12.22 A.33
Owner-occupancy
Not required
for ADUs permitted Jan 2020+
Setbacks (state floor)
4 ft side/rear

California's ADU law is unusually preemptive: state statute (Government Code §65852.2) overrides most local restrictions. But the day-to-day experience is governed by local ordinance, HOA documents, and (once tenanted) the LA rent stabilization framework. Get this right at Stage 01, not at lease-up.

05.01What state law preempts

Local jurisdictions may not require owner-occupancy on ADUs permitted Jan 1, 2020 or later, may not require replacement parking in most transit-served areas, and may not impose minimum lot sizes that block ADU eligibility. Where local code conflicts with §65852.2, state law wins.

05.02HOAs and CC&Rs

Civil Code §4751 prohibits HOAs from unreasonably restricting or denying ADU construction on single-family lots. 'Reasonable' restrictions on size, exterior finish, and setbacks are still allowed — read your CC&Rs and the architectural review process before Stage 01.

05.03Rent stabilization once tenanted

ADUs in the City of LA built after 1978 are exempt from the city's Rent Stabilization Ordinance — but not from the just-cause eviction protections of state law (AB 1482, the Tenant Protection Act). Know which tenancy framework applies before signing a lease.

05.04Insurance and permitting evidence

After certificate of occupancy, notify your homeowner's insurer and add the ADU to the dwelling coverage. Keep stamped as-built plans and the CofO in the project binder — both are sale-disclosure documents in California.
