Mission Canyon, CA
Mission Canyon, CA's wildfire risk, in USFS's own numbers
USFS scores Mission Canyon at the 98th national percentile for wildfire risk to structures (in USFS's highest wildfire-risk band nationally), a figure built from 1,325 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Mission Canyon at the 97th national percentile — 1 points below its risk-to-structures score, a gap driven by how much is actually built there.
Mission Canyon's building exposure, zone by zone
65.7% of Mission Canyon's 1,325 buildings sit in USFS's Direct exposure zone, roughly 871 structures close enough to burnable vegetation for flame contact, not just embers — 34.3% fall in the Indirect, ember-only zone and 0% are Minimal.
Where Mission Canyon ranks
Mission Canyon's risk sits at a similar level relative to California (84th percentile statewide) as it does nationally (98th) — this place isn't unusual for its own state either way. Among the 31,521 US communities USFS scores, Mission Canyon ranks 595 for wildfire risk (1 is highest) and 9,953 by building count (1 is largest). Within California alone, it ranks 252 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Shopping for coverage in Mission Canyon
Because Mission Canyon 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.
Lowering exposure, not just insuring around it
Because Direct exposure dominates in Mission Canyon (65.7%), the highest-leverage fix is defensible space, not roofing or vents alone — covered in the home-hardening guide.
