Does Tyrone, GA need an earthquake retrofit?

Tyrone carries Seismic Design Category B under USGS's ASCE 7-16 model. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Tyrone in the 50th percentile nationally for seismic hazard - higher than 50% of the 4,875 US cities USGS was checked against here.

How Tyrone compares

The raw figures: peak ground acceleration 0.08g, short-period spectral response 0.163g, 1-second spectral response 0.082g. Among 148 Georgia cities in this dataset, Tyrone ranks 113 for seismic hazard, the 24th percentile within the state. About 8,038 people live in Tyrone, Georgia.

What a retrofit costs in Tyrone

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Georgia. 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 Tyrone address.
