Rosemount, MN: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Rosemount is Category A. Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. Nationally, Rosemount ranks above 6% of the 4,875 cities in this dataset for seismic hazard - the 6th percentile.

Where Rosemount sits in Minnesota

The raw figures: peak ground acceleration 0.023g, short-period spectral response 0.047g, 1-second spectral response 0.032g. Among 155 Minnesota cities in this dataset, Rosemount ranks 55 for seismic hazard, the 65th percentile within the state. About 30,581 people live in Rosemount, Minnesota.

Bracing and bolting: the actual cost

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

Insuring against this, not just retrofitting

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 Rosemount address.
