Berkeley Plumbing Code Update:

Budget for Mandatory Earthquake Gas Shut-Off Valves

Property owners and contractors in Berkeley should be aware of an important update to the Berkeley Plumbing Code (BMC Chapter 19.34). The 2022 California Plumbing Code, as adopted locally, incorporates a key amendment—originally approved by the City Council on June 1, 2021 following a referral from the Disaster and Fire Safety Commission. This amendment is now proposed for readoption.

What You Need to Know

Berkeley now requires the installation of motion-activated (seismic) gas shut-off valves whenever a plumbing or mechanical permit is issued for buildings containing fuel gas piping. This rule applies regardless of the permit valuation.

The goal is to reduce or prevent gas-related fires or explosions during major seismic events, an important safety measure for homeowners in earthquake-prone areas.
