Does Saginaw, TX need an earthquake retrofit?

Under the seismic model IBC and ASCE 7 use for new construction, Saginaw is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Saginaw in the 28th percentile nationally for seismic hazard - higher than 28% of the 4,875 US cities USGS was checked against here.

Where Saginaw sits in Texas

USGS's underlying values for Saginaw: 0.047g peak ground acceleration, 0.097g at short period, 0.052g at 1 second. Within Texas alone, Saginaw ranks 110 of 384 cities by seismic hazard - the 72th percentile in-state. Saginaw has a population of about 26,116.

What a retrofit costs in Saginaw

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 Saginaw 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.
