Oconomowoc's Seismic Design Category, explained

Oconomowoc 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 Oconomowoc in the 19th percentile nationally for seismic hazard - higher than 19% of the 4,875 US cities USGS was checked against here.

How Oconomowoc compares

The raw figures: peak ground acceleration 0.036g, short-period spectral response 0.075g, 1-second spectral response 0.048g. Among 157 Wisconsin cities in this dataset, Oconomowoc ranks 54 for seismic hazard, the 66th percentile within the state. About 20,002 people live in Oconomowoc, Wisconsin.

Retrofit economics for Oconomowoc

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 Oconomowoc 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 Oconomowoc address.
