Danville, CA
How exposed is Danville to wildfire?
USFS scores Danville at the 94th national percentile for wildfire risk to structures (in USFS's highest wildfire-risk band nationally), a figure built from 16,958 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Danville's burn probability — fire likelihood with no building count factored in — sits at the 95th percentile nationally.
Danville's building exposure, zone by zone
Indirect exposure is dominant in Danville (75.5% of 16,958 buildings): far enough from burnable vegetation to avoid flame contact, close enough for wind-blown embers. Only 24.6% sit in the Direct zone. At 16,958 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
How Danville compares
Inside California, Danville sits at just the 72nd percentile even though it scores 94th nationally — the state's overall wildfire exposure is high enough to make this a relatively quiet corner of it. Among the 31,521 US communities USFS scores, Danville ranks 1,785 for wildfire risk (1 is highest) and 853 by building count (1 is largest). Within California alone, it ranks 437 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Danville and the insurance market
Because Danville is in California, a wildfire-hazard disclosure is legally required before a sale closes here — unusual nationally, since only these two states mandate it. The state's FAIR Plan alone carried 668,609 policies by the end of 2025. Full detail in the disclosure-law guide.
Lowering exposure, not just insuring around it
Because 75.5% of Danville'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.
