Cheviot's Seismic Design Category, explained

Cheviot 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 Cheviot in the 46th percentile nationally for seismic hazard - higher than 46% of the 4,875 US cities USGS was checked against here.

Cheviot by the numbers

The raw figures: peak ground acceleration 0.072g, short-period spectral response 0.146g, 1-second spectral response 0.078g. Among 254 Ohio cities in this dataset, Cheviot ranks 91 for seismic hazard, the 64th percentile within the state. About 8,640 people live in Cheviot, Ohio.

Bracing and bolting: the actual cost

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

Earthquake insurance for a Cheviot home

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 Cheviot address.

More on how this number was built

The methodology guide covers exactly how USGS's public design-maps API produced Cheviot's numbers. The guide to what a Seismic Design Category actually means covers why a category is never a substitute for an engineer's assessment of one specific house.
