Dennis, MA
Dennis, MA's wildfire risk, in USFS's own numbers
USFS scores Dennis at the 26th national percentile for wildfire risk to structures (close to the middle of USFS's national wildfire-risk range), a figure built from 2,785 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Dennis at the 18th percentile, close to its 26th-percentile risk score.
What "at risk" means for the buildings here
2,785 buildings are counted in Dennis, and 58.7% of them are Indirect exposure — ember-driven risk rather than the 32.9% in Direct exposure or the 8.4% rated Minimal.
How Dennis compares
Within Massachusetts, Dennis ranks higher (53rd percentile) than it does nationally (26th) — one of the more fire-exposed places in a state that, overall, scores lower than that. Among the 31,521 US communities USFS scores, Dennis ranks 23,255 for wildfire risk (1 is highest) and 5,794 by building count (1 is largest). Within Massachusetts alone, it ranks 117 of 248 places by risk. See the full county-by-county picture for Massachusetts on its state page.
What this risk score means for insurance
At the 26th national percentile, Dennis rates moderate for wildfire risk — well short of the threshold where insurers have been withdrawing coverage, though comparing a quote costs nothing either way.
Hardening a home in Dennis
Because 58.7% of Dennis's buildings sit in the Indirect zone, sealing the ember pathway (vents, roofing, gutters) is the intervention this page's data actually supports — see the home-hardening guide.
Where Dennis's figures come from
Every one of the two percentiles behind Dennis's 23,255-place national rank traces to USFS's Wildfire Risk to Communities dataset — see the methodology guide. The exposure-zones guide covers what Dennis's dominant indirect exposure actually means, with real examples from across the dataset.
