Irwindale, CA
Irwindale, CA's wildfire risk, in USFS's own numbers
Irwindale sits at the 75th percentile nationally for wildfire risk to structures — well above the national norm for wildfire risk — per USFS's Wildfire Risk to Communities model, built from its 1,693 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Irwindale at the 75th percentile, close to its 75th-percentile risk score.
Where Irwindale's buildings actually sit
Irwindale rates 83.1% Minimal exposure against just 5.9% Direct and 11.1% Indirect — of 1,693 buildings counted, few sit close enough to burnable vegetation for USFS to flag them individually.
Where Irwindale ranks
Irwindale ranks lower within California (34th percentile statewide) than its 75th national percentile suggests alone — a calmer spot in a state where wildfire risk generally runs high. Among the 31,521 US communities USFS scores, Irwindale ranks 7,753 for wildfire risk (1 is highest) and 8,440 by building count (1 is largest). Within California alone, it ranks 1,044 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Shopping for coverage in Irwindale
Irwindale's 75th-percentile score lands in California, the only two states requiring a wildfire disclosure at sale. California's surplus-lines homeowners market passed 300,000 policies for the first time in 2025, driven by carriers pulling back from wildfire-exposed areas statewide. The disclosure-law guide covers what it requires.
What would actually reduce this score
Irwindale's 83.1% Minimal-exposure share means structure-level hardening matters less here than it would elsewhere — still worth the low-cost basics, per the home-hardening guide.
