Does High Springs, FL need an earthquake retrofit?

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places High Springs in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, High Springs ranks above 19% of the 4,875 cities in this dataset for seismic hazard - the 19th percentile.

Where High Springs sits in Florida

The raw figures: peak ground acceleration 0.037g, short-period spectral response 0.077g, 1-second spectral response 0.047g. Among 228 Florida cities in this dataset, High Springs ranks 22 for seismic hazard, the 91th percentile within the state. About 6,806 people live in High Springs, Florida.

What a retrofit costs in High Springs

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

Insuring against this, not just retrofitting

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 High Springs address.
