Grantsburg, WI
How exposed is Grantsburg to wildfire?
Out of every US place USFS scores, Grantsburg lands at the 82nd percentile for wildfire risk to structures — in USFS's highest wildfire-risk band nationally — a figure built from its 877 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Grantsburg at the 78th national percentile — 3 points below its risk-to-structures score, a gap driven by how much is actually built there.
Where Grantsburg's buildings actually sit
Most of Grantsburg's buildings (52.6%) sit in the Indirect zone, where wind-blown embers rather than flame front are the mechanism USFS is scoring — ember-resistant vents and non-combustible roofing are the interventions this pattern favors, more than defensible space alone.
How Grantsburg compares
Compare Grantsburg's two percentiles: 100th within Wisconsin, only 82nd nationally — a gap of 19 points that marks it as unusually exposed for its own state. Among the 31,521 US communities USFS scores, Grantsburg ranks 5,847 for wildfire risk (1 is highest) and 12,940 by building count (1 is largest). Within Wisconsin alone, it ranks 1 of 808 places by risk. See the full county-by-county picture for Wisconsin on its state page.
What this risk score means for insurance
Grantsburg's very high rating (82nd percentile) puts it among the places where the national carrier-pullback trend is most relevant — not a guarantee of a coverage problem, but a reason to shop rather than assume.
Hardening a home in Grantsburg
With ember exposure the dominant pattern in Grantsburg (52.6% Indirect), vent screens and roofing material tend to matter more than lot clearing alone. The home-hardening guide covers both.
