Oakland, NJ: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Oakland is Category B. 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 Oakland sits at the 64th percentile for seismic hazard among 4,875 US cities.

How Oakland compares

USGS's underlying values for Oakland: 0.173g peak ground acceleration, 0.282g at short period, 0.06g at 1 second. Within New Jersey alone, Oakland ranks 76 of 194 cities by seismic hazard - the 61th percentile in-state. Oakland has a population of about 12,926.

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.

Insuring against this, not just retrofitting

A Oakland 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.

Where Oakland's figures come from

Oakland's Category B and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category B does and doesn't tell you about Oakland.
