FAQ
Seismic Safety Questions
Essential information about earthquake retrofitting for California homeowners.
If your home was built before 1980, it likely needs a retrofit. Many older homes lack proper foundation bolting and cripple wall bracing—making them at higher risk of sliding or collapse during an earthquake.
The Earthquake Brace + Bolt (EBB) program provides state-funded grants of up to $3,000 to help homeowners pay for seismic retrofit work. We assist with the engineering documentation required for program eligibility.
Yes. The California Earthquake Authority (CEA) and many insurance providers offer premium discounts for homes that receive a certified seismic retrofit.
Most single-family retrofits take 1–3 days of construction. Work is typically done in the crawl space with minimal disruption to daily life.
Yes. Seismic retrofitting is a structural upgrade and requires a building permit. We prepare the engineering plans and handle city submission for you.
A cripple wall is the short wood wall sitting between the foundation and the first floor. If unbraced, it is one of the weakest parts of older homes and can collapse during lateral earthquake forces.
