Does Canandaigua, NY need an earthquake retrofit?

Canandaigua 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 Canandaigua sits at the 50th percentile for seismic hazard among 4,875 US cities.

Where Canandaigua sits in New York

The raw figures: peak ground acceleration 0.08g, short-period spectral response 0.151g, 1-second spectral response 0.048g. Among 170 New York cities in this dataset, Canandaigua ranks 140 for seismic hazard, the 18th percentile within the state. About 10,476 people live in Canandaigua, 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.

Earthquake insurance for a Canandaigua 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 Canandaigua address.
