Structure Lock offers seismic benefits and can be paid for by possible grants offered in California.

Would you like to receive up to $3,000 toward an earthquake retrofit of your

house? The Earthquake Brace + Bolt (EBB) program provides homeowners up to

$3,000 to strengthen their home and lessen the potential for earthquake damage.

Many homeowners will decide to hire a contractor to do the retrofit work instead of

doing it themselves. 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 the homeowner is an experienced do-it-yourselfer, a retrofit can cost

less than $3,000.

The EBB program relies on adherence to the California Building Code, Chapter

A3. Chapter A3 is a statewide building code that sets prescriptive standards for

seismic retrofits of existing residential buildings.

Chapter A3 allows:

1. the building department to approve the retrofit for a house with a 4-foot or

shorter cripple wall, without requiring plans prepared by a registered design

professional (architect or engineer).

2. retrofits for houses with cripple walls higher than 4-feet with plans prepared by a

registered design professional.

Surrounding the crawl space under the first floor, many houses have a short wood

framed wall (“cripple wall”) that needs to be strengthened to help prevent the house

from sliding or toppling off of its foundation during an earthquake. Strengthening

involves adding anchor bolts and plywood bracing in the crawl space.
