San Anselmo, CA
San Anselmo, CA's wildfire risk, in USFS's own numbers
USFS's Wildfire Risk to Communities model puts San Anselmo at the 77th national percentile for risk to structures, well above the national norm for wildfire risk — a score built from 5,025 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts San Anselmo at the 78th percentile, close to its 77th-percentile risk score.
San Anselmo's building exposure, zone by zone
Most of San Anselmo's buildings (77.5%) 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. At 5,025 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
How San Anselmo compares
San Anselmo's 77th national percentile looks worse in isolation than its 37th ranking inside California does — this place is on the milder end for its own state, by 41 points. Among the 31,521 US communities USFS scores, San Anselmo ranks 7,144 for wildfire risk (1 is highest) and 3,414 by building count (1 is largest). Within California alone, it ranks 998 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
San Anselmo and the insurance market
San Anselmo's 77th-percentile score lands in California, the only two states requiring a wildfire disclosure at sale. California's surplus-lines homeowners market passed 300,000 policies for the first time in 2025, driven by carriers pulling back from wildfire-exposed areas statewide. The disclosure-law guide covers what it requires.
Lowering exposure, not just insuring around it
With ember exposure the dominant pattern in San Anselmo (77.5% Indirect), vent screens and roofing material tend to matter more than lot clearing alone. The home-hardening guide covers both.
Where San Anselmo's figures come from
San Anselmo's 77th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. The exposure-zones guide covers what San Anselmo's dominant indirect exposure actually means, with real examples from across the dataset.
