Does Absecon, NJ need an earthquake retrofit?

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Absecon in Seismic Design Category A: Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. Nationally, Absecon ranks above 16% of the 4,875 cities in this dataset for seismic hazard - the 16th percentile.

How Absecon compares

The raw figures: peak ground acceleration 0.064g, short-period spectral response 0.125g, 1-second spectral response 0.04g. Among 194 New Jersey cities in this dataset, Absecon ranks 184 for seismic hazard, the 5th percentile within the state. About 9,249 people live in Absecon, 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 Absecon address.
