Seven Hills, OH: what USGS's seismic model says

Seven Hills 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, Seven Hills ranks above 48% of the 4,875 cities in this dataset for seismic hazard - the 48th percentile.

Where Seven Hills sits in Ohio

The raw figures: peak ground acceleration 0.074g, short-period spectral response 0.139g, 1-second spectral response 0.05g. Among 254 Ohio cities in this dataset, Seven Hills ranks 70 for seismic hazard, the 73th percentile within the state. About 11,560 people live in Seven Hills, Ohio.

Retrofit economics for Seven Hills

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 Seven Hills address.
