Warrenton, VA: what USGS's seismic model says

Warrenton 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. Rank it against the rest of the country and Warrenton sits at the 50th percentile for seismic hazard among 4,875 US cities.

Where Warrenton sits in Virginia

The raw figures: peak ground acceleration 0.08g, short-period spectral response 0.15g, 1-second spectral response 0.046g. Among 63 Virginia cities in this dataset, Warrenton ranks 30 for seismic hazard, the 53th percentile within the state. About 10,224 people live in Warrenton, Virginia.

What a retrofit costs in Warrenton

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

Earthquake insurance for a Warrenton 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 Warrenton address.
