Earthquake Retrofitting questions, answered by experts

Almost all new buildings in California need an earthquake shut-off valve. The requirements for an earthquake gas shut-off valve (and who can install it) depend on where you live. For example, according to the Los Angeles Municipal Code, you’re required to hire a licensed contractor to install one whenever you build, sell, or renovate a home. Check with your local building department for your city’s laws on installing, permitting, and inspecting earthquake shut-off valves.

Earthquake gas shut-off valves, or seismic gas shut-off valves, are safety devices that attach to your natural gas line. When an earthquake hits, the valve automatically turns off the flow of gas. Earthquake gas shut-off valves can prevent gas leaks, which are especially dangerous after a quake due to the risk of fire and explosion.

Even if you invested in the cost of a gas shut-off valve for your oven and other appliances, it’s a good idea to add a seismic shut-off valve as an extra safety measure. 

Gas shut-off valves for appliances are manual, meaning someone has to cut off the flow of gas. This leaves room for error, as you might not be home or might be too distracted to think about gas lines during an earthquake. An earthquake valve is automatic and will protect your home from gas-related disasters in the event of an earthquake.

Costs vary as much as timelines. The average earthquake retrofit costs between $3,500 and $8,700. However, homes on hillsides, large homes, and those with rooms over garages can cost up to $12,000 or more. Make sure to get a few estimates to compare the cost and services.

It is not advisable to try to retrofit your home without the expertise of a professional. These projects usually require a consultation with a structural engineer and a plumber for any gas-related adjustments. Working with a professional earthquake retrofitting contractor is the best way to ensure that any structural work done to your home will help protect you and your family.
