Does New Philadelphia, OH need an earthquake retrofit?

New Philadelphia 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, New Philadelphia ranks above 29% of the 4,875 cities in this dataset for seismic hazard - the 29th percentile.

Where New Philadelphia sits in Ohio

The raw figures: peak ground acceleration 0.048g, short-period spectral response 0.099g, 1-second spectral response 0.049g. Among 254 Ohio cities in this dataset, New Philadelphia ranks 248 for seismic hazard, the 2th percentile within the state. About 17,378 people live in New Philadelphia, 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.

What this means for insurance

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 New Philadelphia address.
