Yucaipa, CA
Yucaipa, CA's wildfire risk, in USFS's own numbers
Yucaipa sits at the 99th 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 23,655 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Yucaipa's burn probability — fire likelihood with no building count factored in — sits at the 99th percentile nationally.
Yucaipa's building exposure, zone by zone
USFS puts 60.7% of Yucaipa's 23,655 buildings in the Indirect exposure zone, versus 27.3% Direct and 12.1% Minimal — a place where the fire doesn't need to reach the structure directly for embers to. At 23,655 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
Where Yucaipa ranks
There's little gap between Yucaipa's 99th national percentile and its 91st percentile inside California, which means the state comparison mostly confirms what the national score already shows. Among the 31,521 US communities USFS scores, Yucaipa ranks 254 for wildfire risk (1 is highest) and 545 by building count (1 is largest). Within California alone, it ranks 145 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Yucaipa and the insurance market
Because Yucaipa 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 ember exposure the dominant pattern in Yucaipa (60.7% Indirect), vent screens and roofing material tend to matter more than lot clearing alone. The home-hardening guide covers both.
