Does Mission Viejo, CA need an earthquake retrofit?

Under the seismic model IBC and ASCE 7 use for new construction, Mission Viejo is 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 Mission Viejo in the 90th percentile nationally for seismic hazard - higher than 90% of the 4,875 US cities USGS was checked against here.

What a retrofit costs in Mission Viejo

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.
