New Britain, CT: what USGS's seismic model says

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

New Britain by the numbers

The raw figures: peak ground acceleration 0.106g, short-period spectral response 0.194g, 1-second spectral response 0.055g. Among 21 Connecticut cities in this dataset, New Britain ranks 15 for seismic hazard, the 30th percentile within the state. About 75,871 people live in New Britain, Connecticut.

What a retrofit costs in New Britain

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