Does Gilroy, CA need an earthquake retrofit?
USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Gilroy in Seismic Design Category D: High seismic hazard - this is the category most of coastal California, the Pacific Northwest, and other active fault regions fall into. Code mandates significant seismic detailing and restricts irregular structural configurations. This is the category the Brace + Bolt scope (cripple-wall bracing, foundation bolting) is built for. That puts Gilroy in the 93th percentile nationally for seismic hazard - higher than 93% of the 4,875 US cities USGS was checked against here.
Gilroy by the numbers
USGS's underlying values for Gilroy: 0.614g peak ground acceleration, 1.5g at short period, 0.6g at 1 second. Within California alone, Gilroy ranks 236 of 429 cities by seismic hazard - the 45th percentile in-state. Gilroy has a population of about 60,390.
What a retrofit costs in Gilroy
Cripple-wall bracing and foundation bolting - the scope California's Earthquake Brace + Bolt (EBB) grant funds - typically runs $3,000-$7,000 nationally. Every qualifying household gets a $3,000 base grant, which brings that down to $0-$4,000 out of pocket; income-eligible households ($89,040/year or under) can get up to $10,000 total, covering the retrofit outright in most cases.
Earthquake insurance for a Gilroy home
Gilroy sits in CEA territory, but CEA earthquake coverage is agent-sold only, never direct - so the real first step for a homeowner here is a standard home-insurance quote, then asking that agent about CEA specifically.
Where Gilroy's figures come from
Gilroy's Category D and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. Full Brace + Bolt eligibility rules - beyond what this page can check from a ZIP code alone - are in the retrofit cost and grant guide.
