Rosemont, CA
How exposed is Rosemont to wildfire?
Rosemont's 7,500 buildings earn a 84th-percentile wildfire-risk score nationally under USFS's model — in USFS's highest wildfire-risk band nationally. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Rosemont at the 86th percentile, close to its 84th-percentile risk score.
Rosemont's building exposure, zone by zone
84.2% of Rosemont's 7,500 buildings sit in USFS's Minimal exposure zone, with only 1.4% rated Direct — risk here comes from regional burn probability more than proximity to burnable vegetation at the structure itself. At 7,500 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
Rosemont against the rest of the country
Rosemont's 84th national percentile looks worse in isolation than its 48th ranking inside California does — this place is on the milder end for its own state, by 36 points. Among the 31,521 US communities USFS scores, Rosemont ranks 4,940 for wildfire risk (1 is highest) and 2,281 by building count (1 is largest). Within California alone, it ranks 813 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Shopping for coverage in Rosemont
Because Rosemont 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.
Hardening a home in Rosemont
Even with 84.2% of Rosemont outside USFS's Direct and Indirect zones, basic hardening — gutter maintenance, ember-resistant vents — is inexpensive relative to the regional burn-probability risk noted above. Details in the home-hardening guide.
More on how this number was built
Rosemont's 84th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what minimal exposure implies beyond Rosemont, see the exposure-zones guide.
