Whether an earthquake gas shut-off valve is required depends on your location and circumstances. Certain cities, states, and even insurance providers mandate them, especially in areas with high seismic activity. In California, for example, while laws vary by county, most jurisdictions require a valve to be installed in newly constructed homes or when a home is sold or renovated. The Los Angeles Municipal Code specifically requires a licensed contractor for installation. Even if not required by law, installing a seismic shut-off valve is a wise safety measure. These devices automatically cut off the flow of gas during an earthquake, which can prevent gas leaks, fires, and explosions. It is recommended to check with your local building department for specific laws regarding installation, permitting, and inspections, and to ensure the valve you install is on your city's list of approved models.

According to the Earthquake Country Alliance—a public and private alliance in California that works to improve earthquake and tsunami readiness—reports that unreinforced masonry, such as stone, bricks, and hollow clay tiles, is more susceptible to earthquake damage. The mortar between bricks isn’t as stable as other building materials and methods.

The total time for an earthquake retrofit project varies based on its size and scope. The entire process, from the initial evaluation and planning to the final inspection, typically takes between two weeks and two months. This comprehensive timeline includes bidding, contract paperwork, the permitting and approval process, the actual retrofitting work, and the final inspection.

The physical installation work itself is often quicker, with most jobs taking one week to 10 business days. However, the project may take longer if it requires more extensive work or if the home has structural damage from a previous earthquake. A professional retrofitting expert can provide a more accurate timeline for your specific project after an initial consultation and can also estimate how long the permitting process will take in your area.

Grounding is a great first step to prevent electrical shock, but you can take it further with GFCI outlets and AFCIs (arc fault circuit interrupters). In particular, AFCIs help protect against the type of electrical arcs that cause fires, like if a mouse chews on a wire or your laptop starts overheating at the wall. These are required in some areas of your home.
