Rossford's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Rossford is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Rossford ranks above 44% of the 4,875 cities in this dataset for seismic hazard - the 44th percentile.

Where Rossford sits in Ohio

The raw figures: peak ground acceleration 0.069g, short-period spectral response 0.133g, 1-second spectral response 0.054g. Among 254 Ohio cities in this dataset, Rossford ranks 147 for seismic hazard, the 42th percentile within the state. About 6,353 people live in Rossford, 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.

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 Rossford address.
