Mission Viejo, CA
How exposed is Mission Viejo to wildfire?
USFS's Wildfire Risk to Communities model puts Mission Viejo at the 93rd national percentile for risk to structures, in USFS's highest wildfire-risk band nationally — a score built from 28,796 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Mission Viejo's burn probability — fire likelihood with no building count factored in — sits at the 93rd percentile nationally.
Mission Viejo's building exposure, zone by zone
Mission Viejo rates 50.6% Minimal exposure against just 3% Direct and 46.3% Indirect — of 28,796 buildings counted, few sit close enough to burnable vegetation for USFS to flag them individually. At 28,796 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
How Mission Viejo compares
Mission Viejo ranks lower within California (68th percentile statewide) than its 93rd national percentile suggests alone — a calmer spot in a state where wildfire risk generally runs high. Among the 31,521 US communities USFS scores, Mission Viejo ranks 2,257 for wildfire risk (1 is highest) and 410 by building count (1 is largest). Within California alone, it ranks 502 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 Mission Viejo 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 Mission Viejo
Mission Viejo's 50.6% 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.
Where Mission Viejo's figures come from
Mission Viejo's 93rd-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 Mission Viejo's dominant minimal exposure actually means, with real examples from across the dataset.
