San Jacinto, CA
San Jacinto wildfire risk explained
San Jacinto sits at the 97th percentile nationally for wildfire risk to structures — in USFS's highest wildfire-risk band nationally — per USFS's Wildfire Risk to Communities model, built from its 16,065 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, San Jacinto's burn probability — fire likelihood with no building count factored in — sits at the 97th percentile nationally.
What "at risk" means for the buildings here
San Jacinto rates 45.1% Minimal exposure against just 15.8% Direct and 39.1% Indirect — of 16,065 buildings counted, few sit close enough to burnable vegetation for USFS to flag them individually. At 16,065 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
Where San Jacinto ranks
San Jacinto's 97th national percentile looks worse in isolation than its 80th ranking inside California does — this place is on the milder end for its own state, by 17 points. Among the 31,521 US communities USFS scores, San Jacinto ranks 842 for wildfire risk (1 is highest) and 910 by building count (1 is largest). Within California alone, it ranks 309 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
What this risk score means for insurance
Because San Jacinto 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.
What would actually reduce this score
With 45.1% of buildings rated Minimal exposure, San Jacinto gets less benefit from structure hardening than a Direct- or Indirect-dominant place would — the home-hardening guide explains why the zone matters.
