Piru, CA
Piru wildfire risk explained
Piru's 866 buildings earn a 95th-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 Piru at the 94th national percentile — 1 points below its risk-to-structures score, a gap driven by how much is actually built there.
What "at risk" means for the buildings here
Most of Piru's buildings (57.5%) sit in the Indirect zone, where wind-blown embers rather than flame front are the mechanism USFS is scoring — ember-resistant vents and non-combustible roofing are the interventions this pattern favors, more than defensible space alone.
Where Piru ranks
Piru's 95th national percentile looks worse in isolation than its 75th ranking inside California does — this place is on the milder end for its own state, by 20 points. Among the 31,521 US communities USFS scores, Piru ranks 1,437 for wildfire risk (1 is highest) and 13,019 by building count (1 is largest). Within California alone, it ranks 393 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Shopping for coverage in Piru
Piru 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 95th-percentile score like Piru's can end up mattering for.

What would actually reduce this score
Piru's 57.5% Indirect-exposure share points at embers, not flame contact, as the main pathway — ember-resistant vents and non-combustible roofing rank ahead of defensible space here. Detail in the home-hardening guide.
