Dover, OH: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Dover is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Dover ranks above 29% of the 4,875 cities in this dataset for seismic hazard - the 29th percentile.

Where Dover sits in Ohio

The raw figures: peak ground acceleration 0.049g, short-period spectral response 0.1g, 1-second spectral response 0.049g. Among 254 Ohio cities in this dataset, Dover ranks 246 for seismic hazard, the 3th percentile within the state. About 12,946 people live in Dover, Ohio.

Retrofit economics for Dover

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 Dover 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 Dover address.
