Whitehouse's Seismic Design Category, explained

Whitehouse 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. That puts Whitehouse in the 45th percentile nationally for seismic hazard - higher than 45% of the 4,875 US cities USGS was checked against here.

How Whitehouse compares

USGS's underlying values for Whitehouse: 0.071g peak ground acceleration, 0.135g at short period, 0.055g at 1 second. Within Ohio alone, Whitehouse ranks 116 of 254 cities by seismic hazard - the 55th percentile in-state. Whitehouse has a population of about 5,083.

Bracing and bolting: the actual cost

A full earthquake retrofit typically runs $5,000-$10,000 nationally (around $7,000 typical), driven mainly by house size and foundation type, not by Ohio specifically. California's Earthquake Brace + Bolt grant, which covers a large share of this cost, is a California-only program and does not apply in Ohio.

What this means for insurance

A Whitehouse homeowner cannot buy a standalone earthquake policy in most cases - it is added to an existing homeowners policy as an endorsement, so the place to start is a regular home-insurance quote.

Where Whitehouse's figures come from

Whitehouse's Category B and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category B does and doesn't tell you about Whitehouse.
