Yermo, CA
Yermo, CA's wildfire risk, in USFS's own numbers
Yermo sits at the 33rd percentile nationally for wildfire risk to structures — close to the middle of USFS's national wildfire-risk range — per USFS's Wildfire Risk to Communities model, built from its 391 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Yermo's burn probability — fire likelihood with no building count factored in — sits at the 37th percentile nationally.
Where Yermo's buildings actually sit
391 buildings are counted in Yermo, and 91.3% of them are Indirect exposure — ember-driven risk rather than the 8.7% in Direct exposure or the 0% rated Minimal.
Yermo against the rest of the country
Yermo ranks lower within California (4th percentile statewide) than its 33rd national percentile suggests alone — a calmer spot in a state where wildfire risk generally runs high. Among the 31,521 US communities USFS scores, Yermo ranks 21,073 for wildfire risk (1 is highest) and 19,388 by building count (1 is largest). Within California alone, it ranks 1,515 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
Yermo sits in California, one of two states that legally require a wildfire-risk disclosure at sale. California's FAIR Plan, the state's insurer of last resort, ended 2025 with 668,609 residential policies after adding 21,859 in Q4 alone — the kind of market shift a 33rd-percentile score like Yermo's can end up mattering for.

What would actually reduce this score
With ember exposure the dominant pattern in Yermo (91.3% Indirect), vent screens and roofing material tend to matter more than lot clearing alone. The home-hardening guide covers both.
Where Yermo's figures come from
Yermo's 33rd-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. The exposure-zones guide covers what Yermo's dominant indirect exposure actually means, with real examples from across the dataset.
