Mountain House, CA
Mountain House, CA's wildfire risk, in USFS's own numbers
USFS scores Mountain House at the 92nd national percentile for wildfire risk to structures (in USFS's highest wildfire-risk band nationally), a figure built from 6,528 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 Mountain House at the 93rd percentile, close to its 92nd-percentile risk score.
What "at risk" means for the buildings here
85.9% of Mountain House's 6,528 buildings fall in USFS's Indirect exposure zone — ember cast rather than direct flame — against 5.2% Direct and 9% Minimal. Vent screens and roofing material matter more here than lot clearing alone. At 6,528 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
Mountain House against the rest of the country
Inside California, Mountain House sits at just the 66th percentile even though it scores 92nd 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, Mountain House ranks 2,603 for wildfire risk (1 is highest) and 2,662 by building count (1 is largest). Within California alone, it ranks 540 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Mountain House and the insurance market
Because Mountain House 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 85.9% of Mountain House'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.
