Vallejo, CA
How exposed is Vallejo to wildfire?
Out of every US place USFS scores, Vallejo lands at the 89th percentile for wildfire risk to structures — in USFS's highest wildfire-risk band nationally — a figure built from its 40,917 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Vallejo's burn probability — fire likelihood with no building count factored in — sits at the 89th percentile nationally.
Where Vallejo's buildings actually sit
USFS classifies 71.4% of Vallejo's buildings as Minimal exposure, the largest of the three zones here by a wide margin over 1.9% Direct and 26.7% Indirect — a landscape-level risk rather than a building-by-building one. At 40,917 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
How Vallejo compares
Inside California, Vallejo sits at just the 59th percentile even though it scores 89th nationally — the state's overall wildfire exposure is high enough to make this a relatively quiet corner of it. Among the 31,521 US communities USFS scores, Vallejo ranks 3,492 for wildfire risk (1 is highest) and 234 by building count (1 is largest). Within California alone, it ranks 651 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Shopping for coverage in Vallejo
Because Vallejo 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 Vallejo
Vallejo's 71.4% 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.
