Odessa's Seismic Design Category, explained

Odessa carries Seismic Design Category B under USGS's ASCE 7-16 model. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Odessa in the 30th percentile nationally for seismic hazard - higher than 30% of the 4,875 US cities USGS was checked against here.

How Odessa compares

The raw figures: peak ground acceleration 0.05g, short-period spectral response 0.106g, 1-second spectral response 0.07g. Among 135 Missouri cities in this dataset, Odessa ranks 106 for seismic hazard, the 22th percentile within the state. About 5,689 people live in Odessa, Missouri.

Bracing and bolting: the actual cost

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

What this means for insurance

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 Odessa address.
