Plumbing Permits: Brentwood vs Richmond

Brentwood requires plumbing permits for water heater replacements, repipes, sewer lateral work, gas line modifications, and most fixture relocations under the 2022 California Plumbing Code as adopted by the city. Like-for-like fixture swaps (faucets, toilets at the same location) generally do not require a permit, but water heaters always do.

Richmond requires plumbing permits for water heater replacements, repipes, sewer lateral work, gas line modifications, and fixture additions under the 2022 California Plumbing Code, with mandatory sewer lateral compliance at point of sale.
