Holland, MI: what USGS's seismic model says

Holland 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 Holland in the 24th percentile nationally for seismic hazard - higher than 24% of the 4,875 US cities USGS was checked against here.

Holland by the numbers

USGS's underlying values for Holland: 0.043g peak ground acceleration, 0.088g at short period, 0.049g at 1 second. Within Michigan alone, Holland ranks 97 of 153 cities by seismic hazard - the 37th percentile in-state. Holland has a population of about 35,023.

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 Michigan 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 Michigan.

What this means for insurance

A Holland 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 Holland's figures come from

Holland'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 Holland.
