Plumbing Permits: Brentwood vs San Ramon

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.

Plumbing permits in San Ramon are issued through Contra Costa County Building Inspection Division and governed by the 2022 California Plumbing Code. Permits are required for water heater replacements, repiping, sewer lateral work, gas line modifications, backflow prevention devices, and fixture additions. Like-for-like fixture swaps (faucets, toilets in existing location) generally do not require permits, but water heater and gas work always do. EBMUD or DSRSD serves as the water provider depending on location, and Central Contra Costa Sanitary District (Central San) handles sewer permits.
