Pasadena, TX: what USGS's seismic model says

Pasadena 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. Rank it against the rest of the country and Pasadena sits at the 12th percentile for seismic hazard among 4,875 US cities.

Where Pasadena sits in Texas

The raw figures: peak ground acceleration 0.033g, short-period spectral response 0.068g, 1-second spectral response 0.039g. Among 384 Texas cities in this dataset, Pasadena ranks 221 for seismic hazard, the 43th percentile within the state. About 149,617 people live in Pasadena, Texas.

What a retrofit costs in Pasadena

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 Pasadena address.
