Chino Hills, CA
How exposed is Chino Hills to wildfire?
USFS's Wildfire Risk to Communities model puts Chino Hills at the 95th national percentile for risk to structures, in USFS's highest wildfire-risk band nationally — a score built from 22,936 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Chino Hills at the 95th national percentile — 1 points above its risk-to-structures score, a gap driven by how much is actually built there.
Where Chino Hills's buildings actually sit
22,936 buildings are counted in Chino Hills, and 59.4% of them are Indirect exposure — ember-driven risk rather than the 11.4% in Direct exposure or the 29.2% rated Minimal. At 22,936 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
Chino Hills against the rest of the country
Inside California, Chino Hills sits at just the 73rd percentile even though it scores 95th 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, Chino Hills ranks 1,693 for wildfire risk (1 is highest) and 575 by building count (1 is largest). Within California alone, it ranks 427 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Chino Hills and the insurance market
Chino Hills's 95th-percentile score lands in California, the only two states requiring a wildfire disclosure at sale. California's surplus-lines homeowners market passed 300,000 policies for the first time in 2025, driven by carriers pulling back from wildfire-exposed areas statewide. The disclosure-law guide covers what it requires.
Hardening a home in Chino Hills
Chino Hills's 59.4% 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.
Where Chino Hills's figures come from
Chino Hills's 95th-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 Chino Hills's dominant indirect exposure actually means, with real examples from across the dataset.
