Batavia's Seismic Design Category, explained

Batavia 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 Batavia in the 57th percentile nationally for seismic hazard - higher than 57% of the 4,875 US cities USGS was checked against here.

Batavia by the numbers

The raw figures: peak ground acceleration 0.103g, short-period spectral response 0.182g, 1-second spectral response 0.048g. Among 170 New York cities in this dataset, Batavia ranks 108 for seismic hazard, the 37th percentile within the state. About 15,071 people live in Batavia, New York.

What a retrofit costs in Batavia

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.

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 Batavia address.
