Jersey City, NJ: what USGS's seismic model says

Jersey City 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. Rank it against the rest of the country and Jersey City sits at the 64th percentile for seismic hazard among 4,875 US cities.

Jersey City by the numbers

USGS's underlying values for Jersey City: 0.178g peak ground acceleration, 0.288g at short period, 0.06g at 1 second. Within New Jersey alone, Jersey City ranks 63 of 194 cities by seismic hazard - the 68th percentile in-state. Jersey City has a population of about 302,824.

Retrofit economics for Jersey City

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.

What this means for insurance

A Jersey City 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.
