Does DeBary, FL need an earthquake retrofit?

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places DeBary in Seismic Design Category A: Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. That puts DeBary in the 11th percentile nationally for seismic hazard - higher than 11% of the 4,875 US cities USGS was checked against here.

DeBary by the numbers

The raw figures: peak ground acceleration 0.031g, short-period spectral response 0.066g, 1-second spectral response 0.036g. Among 228 Florida cities in this dataset, DeBary ranks 54 for seismic hazard, the 77th percentile within the state. About 23,468 people live in DeBary, Florida.

What a retrofit costs in DeBary

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.

What this means for insurance

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 DeBary address.
