Legalizing a non-conforming unit in Lawndale

The city wrote the statute into its own code

In 2025 Lawndale adopted Ordinance 1208-25, amending LMC § 17.48.056 specifically to implement AB 2533 and SB 1211. The ordinance states directly that the city will not deny an application to legalize an unpermitted unit predating January 1, 2020 unless correcting the violation is necessary to comply with Health & Safety Code § 17920.3. A city that has codified the protection is a city that will not argue about it.

Plan check runs through the County

Lawndale is a Los Angeles County contract city for building and safety, and its permit fees are set as a multiple of the County schedule.

Rent control

Lawndale has no local rent stabilization ordinance. Rent increases are governed by the statewide Tenant Protection Act: five percent plus regional CPI to a maximum of ten percent, with units exempt for fifteen years from the date their certificate of occupancy is issued.

What the city can and cannot do

Lawndale cannot deny a permit for a pre-2020 unit because it violates building standards or the local ADU ordinance. It can deny only if it finds that correcting the violation is necessary to meet the substandard-building threshold in Health & Safety Code § 17920.3.

That is a far narrower test than full compliance with current code. A unit can fall short of today's standards in a dozen ways and still be permitted, so long as none of them makes the building substandard.
