Rochester, NY: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Rochester in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Rochester in the 53th percentile nationally for seismic hazard - higher than 53% of the 4,875 US cities USGS was checked against here.

How Rochester compares

USGS's underlying values for Rochester: 0.087g peak ground acceleration, 0.161g at short period, 0.048g at 1 second. Within New York alone, Rochester ranks 132 of 170 cities by seismic hazard - the 22th percentile in-state. Rochester has a population of about 207,282.

Bracing and bolting: the actual cost

A full earthquake retrofit typically runs $5,000-$10,000 nationally (around $7,000 typical), driven mainly by house size and foundation type, not by New York specifically. California's Earthquake Brace + Bolt grant, which covers a large share of this cost, is a California-only program and does not apply in New York.

Earthquake insurance for a Rochester home

A Rochester homeowner cannot buy a standalone earthquake policy in most cases - it is added to an existing homeowners policy as an endorsement, so the place to start is a regular home-insurance quote.

Where Rochester's figures come from

Rochester's Category B and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category B does and doesn't tell you about Rochester.
