Plumbing Permits: Pittsburg vs Walnut Creek

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.

Walnut Creek requires plumbing permits for most plumbing work including water heater replacement, repiping, sewer lateral repairs, and fixture additions. The California Plumbing Code (CPC) governs installations, and EBMUD sewer lateral compliance applies at property transfer.
