Full Breakdown
235 adopts the latest printing of the 2025 California Plumbing Code (Part 5, Title 24 of the California Code of Regulations) as the county's plumbing code, with three local amendments. 315(B), which limits no-permit plumbing work to stopping small leaks and clearing stoppages, provided the repair does not require replacing or rearranging pipes, valves, or fixtures. 1 requires every new gas piping system, replacement gas piping system, and new or replacement gas meter installation to have a listed, approved earthquake-actuated gas shutoff valve, sized for the system's full BTU demand, installed immediately before the meter or propane tank connection and before utilities are released.
Third, Appendix M of the 2025 Plumbing Code, the water demand calculator, is formally adopted for sizing water supply piping. 315 exemption list. 1 flow standard even though the swap itself is permit-exempt.
Violations & Fines
Plumbing work performed without the required permit, or a gas line or meter installation completed without the mandated earthquake-actuated shutoff valve, is subject to enforcement by the Building Official under the general permit-compliance provisions of Chapter 12.10; unpermitted work can be red-tagged and requires retroactive permitting and inspection before use or occupancy is approved.
