Troy, NY: what USGS's seismic model says

Troy 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 Troy sits at the 57th percentile for seismic hazard among 4,875 US cities.

How Troy compares

The raw figures: peak ground acceleration 0.104g, short-period spectral response 0.196g, 1-second spectral response 0.06g. Among 170 New York cities in this dataset, Troy ranks 106 for seismic hazard, the 38th percentile within the state. About 51,065 people live in Troy, New York.

What a retrofit costs in Troy

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.

Earthquake insurance for a Troy 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 Troy address.
