Retaining Wall Permit Requirements in Temple City, CA
Temple City is an incorporated LA County contract city that issues building permits under its own name through the City Community Development Department's Building & Safety Division at City Hall. Day-to-day building official, plan check, inspection, and permit-counter services are contracted to a private firm, Transtech Engineers, Inc., which has provided these services since 2012, so inspections are contracted but the AHJ is the city. Plan check and permit fees (except encroachment) are set at 120 percent of the County of Los Angeles fee schedule and the city directs applicants to LA County Public Works for the base amounts. California enforces statewide Title 24, currently the 2025 California Residential Code (based on the 2024 IRC) effective January 1, 2026.
