San Jose follows California Plumbing Code and local building code requirements for seismic gas shutoff valves (SGSOV). Installation is required for new construction, certain permitted renovations, and at point of sale. Valves must be installed downstream of the gas meter and carry manufacturer warranties. San Jose is served by PG&E, which provides gas shutoff guidance for seismic safety.
Seismic gas shutoff valve requirements in San Jose follow the California Plumbing Code (CPC) and San Jose Municipal Code building provisions. An approved seismic gas shutoff valve or excess flow shutoff valve must be installed on new construction with gas piping and when existing buildings undergo certain permitted renovations. Point-of-sale requirements follow California Civil Code provisions requiring disclosure and, in many jurisdictions, installation. San Jose is located in a high seismic risk area near the Hayward and Calaveras faults, making gas shutoff valves particularly important. The valve must be installed downstream of the gas utility meter, rigidly mounted to the building exterior or other approved location. Valves must meet state certification requirements and carry manufacturer warranties. PG&E, the gas utility serving San Jose, provides guidance on gas safety during earthquakes and coordinates with the city on gas shutoff valve compliance. Installation requires a plumbing permit from the San Jose Building Division. Only state-approved valve models may be used.
Building permit hold for non-compliance during new construction or renovation. Point-of-sale non-compliance: potential liability for gas-related damage in seismic event. Installation without permit: code violation citation.
