Brownwood, TX: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Brownwood is Category A. Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. Nationally, Brownwood ranks above 9% of the 4,875 cities in this dataset for seismic hazard - the 9th percentile.

Where Brownwood sits in Texas

The raw figures: peak ground acceleration 0.026g, short-period spectral response 0.057g, 1-second spectral response 0.034g. Among 384 Texas cities in this dataset, Brownwood ranks 310 for seismic hazard, the 19th percentile within the state. About 18,772 people live in Brownwood, Texas.

What a retrofit costs in Brownwood

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.

Insuring against this, not just retrofitting

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 Brownwood address.
