Claremont, CA
How exposed is Claremont to wildfire?
Out of every US place USFS scores, Claremont lands at the 100th percentile for wildfire risk to structures — in USFS's highest wildfire-risk band nationally — a figure built from its 12,543 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Claremont at the 100th percentile, close to its 100th-percentile risk score.
Claremont's building exposure, zone by zone
Most of Claremont's buildings (46.5%) 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 12,543 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
Where Claremont ranks
There's little gap between Claremont's 100th national percentile and its 99th percentile inside California, which means the state comparison mostly confirms what the national score already shows. Among the 31,521 US communities USFS scores, Claremont ranks 25 for wildfire risk (1 is highest) and 1,228 by building count (1 is largest). Within California alone, it ranks 14 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Claremont and the insurance market
Claremont sits in California, one of two states that legally require a wildfire-risk disclosure at sale. California's FAIR Plan, the state's insurer of last resort, ended 2025 with 668,609 residential policies after adding 21,859 in Q4 alone — the kind of market shift a 100th-percentile score like Claremont's can end up mattering for.

What would actually reduce this score
Because 46.5% of Claremont'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.
