Kenosha, WI: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Kenosha is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Kenosha in the 25th percentile nationally for seismic hazard - higher than 25% of the 4,875 US cities USGS was checked against here.

Where Kenosha sits in Wisconsin

The raw figures: peak ground acceleration 0.044g, short-period spectral response 0.089g, 1-second spectral response 0.053g. Among 157 Wisconsin cities in this dataset, Kenosha ranks 9 for seismic hazard, the 95th percentile within the state. About 99,578 people live in Kenosha, Wisconsin.

What a retrofit costs in Kenosha

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Wisconsin. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

Earthquake insurance for a Kenosha home

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 Kenosha address.
