Is your house earthquake ready?

If not, you may be eligible for up to $3,000 from a newly expanded state program toward a seismic retrofit, which will keep your home attached to its foundation during the next major earthquake.

The funding — available starting Wednesday, and only for 30 days — is offered for the first time to eligible homes in the Bay Area cities of Hayward, San Mateo, Redwood City, San Bruno, Daly City, Colma and El Cerrito. Funds are already available for homeowners in San Francisco, Oakland, Berkeley, Burlingame, Millbrae, Woodside and eight other Bay Area cities.

The Earthquake Brace + Bolt Program is designed to help homeowners in ZIP codes that face the highest risk of earthquake damage to homes, based on local geological hazards combined with the vulnerability due to home construction type.

Wednesday’s announcement at a southern California news conference represents a 31 percent increase in eligible ZIP codes over what was available in 2016. This year, the program expects to provide grants for 2,000 retrofits in the state, up from 1,600 last year.

In a strong earthquake, the crawl space under a home is vulnerable to collapse, causing it to fall off its foundation. A seismic retrofit bolts a house to its foundation and adds plywood to brace the walls in the crawl space.

A typical retrofit may cost between $3,000 and $7,000 depending on the location and size of the house, contractor fees, and the amount of materials and work involved. If you’re an experienced do-it-yourselfer, a retrofit can cost less than $3,000.

Houses that qualify for the program tend to be: wood-framed construction built before 1979; built on a level or low slope; constructed with a 4-foot (or less) “cripple wall” under the first floor and have a raised foundation.

Registration for this program, funded by the State of California and the California Earthquake Authority, is only open through Feb. 27.
