Plumbing Permits: Richmond vs San Ramon

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.

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.
