Jerome, ID: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Jerome is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Jerome in the 49th percentile nationally for seismic hazard - higher than 49% of the 4,875 US cities USGS was checked against here.

Where Jerome sits in Idaho

The raw figures: peak ground acceleration 0.077g, short-period spectral response 0.175g, 1-second spectral response 0.08g. Among 36 Idaho cities in this dataset, Jerome ranks 36 for seismic hazard, the 0th percentile within the state. About 13,481 people live in Jerome, Idaho.

Bracing and bolting: the actual cost

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Idaho. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

Earthquake insurance for a Jerome home

Outside California, earthquake coverage is typically sold as an endorsement added to a standard homeowners policy, not a separate product - worth asking about directly when getting a home-insurance quote for a Jerome address.
