Shelby, OH: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Shelby is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Shelby in the 39th percentile nationally for seismic hazard - higher than 39% of the 4,875 US cities USGS was checked against here.

How Shelby compares

USGS's underlying values for Shelby: 0.063g peak ground acceleration, 0.123g at short period, 0.054g at 1 second. Within Ohio alone, Shelby ranks 186 of 254 cities by seismic hazard - the 27th percentile in-state. Shelby has a population of about 9,238.

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.

Earthquake insurance for a Shelby home

A Shelby 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 Shelby's figures come from

Shelby'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 Shelby.
