Warwick's Seismic Design Category, explained

Warwick 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 Warwick in the 61th percentile nationally for seismic hazard - higher than 61% of the 4,875 US cities USGS was checked against here.

Warwick by the numbers

The raw figures: peak ground acceleration 0.146g, short-period spectral response 0.246g, 1-second spectral response 0.057g. Among 170 New York cities in this dataset, Warwick ranks 75 for seismic hazard, the 56th percentile within the state. About 6,546 people live in Warwick, New York.

Bracing and bolting: the actual cost

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