Plumbing Permits: Pittsburg vs San Ramon

Pittsburg requires plumbing permits under the California Plumbing Code adopted through Municipal Code Title 15 for water heater replacement, repipes, sewer laterals, gas lines, and fixture additions. Like-for-like faucet and fixture swaps are generally exempt. Permits require licensed C-36 plumbing contractors or owner-builders, and inspections include rough-in pressure tests and finals.

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.
