Does Mabank, TX need an earthquake retrofit?

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Mabank in Seismic Design 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 Mabank sits at the 22th percentile for seismic hazard among 4,875 US cities.

How Mabank compares

USGS's underlying values for Mabank: 0.042g peak ground acceleration, 0.089g at short period, 0.054g at 1 second. Within Texas alone, Mabank ranks 153 of 384 cities by seismic hazard - the 60th percentile in-state. Mabank has a population of about 7,021.

What a retrofit costs in Mabank

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.

Insuring against this, not just retrofitting

A Mabank 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.
