Byron, CA
How exposed is Byron to wildfire?
Byron's 919 buildings earn a 91st-percentile wildfire-risk score nationally under USFS's model — in USFS's highest wildfire-risk band nationally. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Byron at the 92nd national percentile — 1 points above its risk-to-structures score, a gap driven by how much is actually built there.
Byron's building exposure, zone by zone
51.4% of Byron's 919 buildings sit in USFS's Direct exposure zone, roughly 472 structures close enough to burnable vegetation for flame contact, not just embers — 39.1% fall in the Indirect, ember-only zone and 9.6% are Minimal.
Byron against the rest of the country
Byron's 91st national percentile looks worse in isolation than its 64th ranking inside California does — this place is on the milder end for its own state, by 27 points. Among the 31,521 US communities USFS scores, Byron ranks 2,761 for wildfire risk (1 is highest) and 12,557 by building count (1 is largest). Within California alone, it ranks 559 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 Byron 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
Byron's 51.4% Direct-exposure share means lot clearing around the structure typically outweighs any single material upgrade here. The home-hardening guide ranks the options for a place shaped like this.
