Does Metuchen, NJ need an earthquake retrofit?

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Metuchen in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Metuchen in the 63th percentile nationally for seismic hazard - higher than 63% of the 4,875 US cities USGS was checked against here.

How Metuchen compares

The raw figures: peak ground acceleration 0.162g, short-period spectral response 0.267g, 1-second spectral response 0.057g. Among 194 New Jersey cities in this dataset, Metuchen ranks 103 for seismic hazard, the 47th percentile within the state. About 15,470 people live in Metuchen, New Jersey.

Bracing and bolting: the actual cost

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for New Jersey. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

What this means for insurance

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 Metuchen address.
