North Olmsted's Seismic Design Category, explained

North Olmsted 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. Nationally, North Olmsted ranks above 45% of the 4,875 cities in this dataset for seismic hazard - the 45th percentile.

How North Olmsted compares

The raw figures: peak ground acceleration 0.07g, short-period spectral response 0.133g, 1-second spectral response 0.05g. Among 254 Ohio cities in this dataset, North Olmsted ranks 118 for seismic hazard, the 54th percentile within the state. About 31,690 people live in North Olmsted, Ohio.

Retrofit economics for North Olmsted

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 North Olmsted address.
