Eastpointe's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Eastpointe is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Eastpointe in the 29th percentile nationally for seismic hazard - higher than 29% of the 4,875 US cities USGS was checked against here.

Where Eastpointe sits in Michigan

USGS's underlying values for Eastpointe: 0.048g peak ground acceleration, 0.097g at short period, 0.045g at 1 second. Within Michigan alone, Eastpointe ranks 60 of 153 cities by seismic hazard - the 61th percentile in-state. Eastpointe has a population of about 33,943.

Retrofit economics for Eastpointe

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.

Insuring against this, not just retrofitting

A Eastpointe 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 Eastpointe's figures come from

Eastpointe'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 Eastpointe.
