Caddo Mills, TX: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Caddo Mills is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Caddo Mills in the 33th percentile nationally for seismic hazard - higher than 33% of the 4,875 US cities USGS was checked against here.

How Caddo Mills compares

The raw figures: peak ground acceleration 0.055g, short-period spectral response 0.114g, 1-second spectral response 0.06g. Among 384 Texas cities in this dataset, Caddo Mills ranks 62 for seismic hazard, the 84th percentile within the state. About 5,257 people live in Caddo Mills, Texas.

Retrofit economics for Caddo Mills

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Texas. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

Outside California, earthquake coverage is typically sold as an endorsement added to a standard homeowners policy, not a separate product - worth asking about directly when getting a home-insurance quote for a Caddo Mills address.
