Foundation work in Los Angeles
The Los Angeles Department of Building and Safety (LADBS) issues permits for sill plate anchor bolts and plywood on cripple walls (the short framed walls between foundation and first floor) without plan check. Its express-permit bulletin IB P/GI 2020-003 (revised 5-28-2024) lists that work under City Standard Plan #1, with or without a foundation replacement. Jobs that need plan check go through ePlanLA. LADBS's Homeowner's Guide to Permits and Inspections lists a foundation plan with floor-framing details among the minimum plans, and an engineered design needs the engineer's or architect's stamped, signed calculations.
On lots inside a Hillside Construction Regulation district (first set up by Ordinance No. 184,827 on March 22, 2017), weekday work runs 8:00 AM to 6:00 PM and Saturdays allow interior work only. Apartment owners face a separate mandate. The Soft-Story Retrofit Program (Ordinances 183893 and 184081) covers wood-frame buildings of 2 or more stories, built under codes from before January 1, 1978, with parking or open space on the ground floor; it doesn't reach residential buildings of 3 or fewer units.
The California Earthquake Authority gives up to a 25% premium discount for a retrofitted pre-1980 wood-framed house on a raised foundation with the water heater secured, once an inspection professional signs the CEA's Dwelling Retrofit Verification form. Here, 71.0% of homes predate 1980 (ACS 2023). Call 311, or (866) 452-2489 inside the county; inspections need at least 24 hours' notice. LADBS doesn't post a printed fee table, so price the permit in its online Permit Fee Calculator, the department's own fee tool.

Permits for foundation repair work in Los Angeles
If Los Angeles has its own building department, start there and ask who issues permits for foundation, waterproofing and sump work.
The California Building Standards Code says no structure may be altered, repaired or improved without a permit from the building official, and CSLB adds that requirements vary by city and county. The building department for your address decides whether a given foundation, waterproofing or sump job counts.
