Does Celina, TX need an earthquake retrofit?

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Celina in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Celina ranks above 41% of the 4,875 cities in this dataset for seismic hazard - the 41th percentile.

Where Celina sits in Texas

USGS's underlying values for Celina: 0.065g peak ground acceleration, 0.13g at short period, 0.06g at 1 second. Within Texas alone, Celina ranks 30 of 384 cities by seismic hazard - the 92th percentile in-state. Celina has a population of about 51,661.

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 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.

Earthquake insurance for a Celina home

A Celina 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 Celina's figures come from

Celina'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 Celina.
