Does Camden, NJ need an earthquake retrofit?

Under the seismic model IBC and ASCE 7 use for new construction, Camden is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Camden ranks above 56% of the 4,875 cities in this dataset for seismic hazard - the 56th percentile.

Where Camden sits in New Jersey

USGS's underlying values for Camden: 0.099g peak ground acceleration, 0.179g at short period, 0.047g at 1 second. Within New Jersey alone, Camden ranks 158 of 194 cities by seismic hazard - the 19th percentile in-state. Camden has a population of about 71,749.

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 Jersey 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 Jersey.

Earthquake insurance for a Camden home

A Camden 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.
