Hudson's Seismic Design Category, explained
Hudson 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. Nationally, Hudson ranks above 46% of the 4,875 cities in this dataset for seismic hazard - the 46th percentile.
Hudson by the numbers
USGS's underlying values for Hudson: 0.071g peak ground acceleration, 0.134g at short period, 0.049g at 1 second. Within Ohio alone, Hudson ranks 98 of 254 cities by seismic hazard - the 62th percentile in-state. Hudson has a population of about 23,073.
What a retrofit costs in Hudson
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 Ohio 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 Ohio.
What this means for insurance
A Hudson 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 Hudson's figures come from
Hudson'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 Hudson.
