The third largest market we serve
16,374 apartment units, more than two thirds of them built before 1980, and none of it in the coastal zone.
The city has a name for this
Hawthorne's adopted fee schedule carries a line item titled Permit to Legalize Unpermitted ADU or JADU. A city with a named fee for legalization has a process for it, which usually means a shorter conversation at the counter.
Already in the code
HMC Chapter 17.21 permits conversion of non-habitable space in multifamily buildings up to twenty-five percent of the existing unit count, and bars the city from requiring correction of nonconforming zoning conditions as a condition of approval.
Rent control
Hawthorne 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
Hawthorne 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.
