DSA Gas Shut-off Valves Certification Program

The Division of the State Architect (DSA) is certifying two different types of gas shut off valves for residential use: 1) earthquake sensitive gas shut off valves (ESV) and 2) excess flow automatic gas shut off valves (EFV). DSA derives its authority to certify these valves from the Health and Safety Code.

For questions regarding the state certification program for gas shutoff valves, contact Paul Vetter, (916)324-1280, paul.vetter@dgs.ca.gov.

For requirements regarding installation of gas shutoff valves, contact your local building department.
