Does Orange, TX need an earthquake retrofit?

Orange 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 Orange sits at the 21th percentile for seismic hazard among 4,875 US cities.

How Orange compares

USGS's underlying values for Orange: 0.04g peak ground acceleration, 0.081g at short period, 0.047g at 1 second. Within Texas alone, Orange ranks 164 of 384 cities by seismic hazard - the 57th percentile in-state. Orange has a population of about 19,275.

What a retrofit costs in Orange

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 Texas 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 Texas.

What this means for insurance

A Orange 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 Orange's figures come from

Orange'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 Orange.
