Does Ingleside, TX need an earthquake retrofit?

Ingleside carries Seismic Design Category A under USGS's ASCE 7-16 model. Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. That puts Ingleside in the 10th percentile nationally for seismic hazard - higher than 10% of the 4,875 US cities USGS was checked against here.

How Ingleside compares

USGS's underlying values for Ingleside: 0.028g peak ground acceleration, 0.058g at short period, 0.018g at 1 second. Within Texas alone, Ingleside ranks 288 of 384 cities by seismic hazard - the 25th percentile in-state. Ingleside has a population of about 10,155.

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 Ingleside home

A Ingleside 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.
