Quartz Hill, CA
How exposed is Quartz Hill to wildfire?
Quartz Hill's 5,307 buildings earn a 85th-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 Quartz Hill at the 83rd national percentile — 2 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
USFS classifies 72.2% of Quartz Hill's buildings as Minimal exposure, the largest of the three zones here by a wide margin over 21.6% Direct and 6.2% Indirect — a landscape-level risk rather than a building-by-building one. At 5,307 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
Where Quartz Hill ranks
Quartz Hill's 85th national percentile looks worse in isolation than its 50th ranking inside California does — this place is on the milder end for its own state, by 35 points. Among the 31,521 US communities USFS scores, Quartz Hill ranks 4,782 for wildfire risk (1 is highest) and 3,253 by building count (1 is largest). Within California alone, it ranks 794 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Quartz Hill and the insurance market
Quartz Hill's 85th-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.
What would actually reduce this score
Even with 72.2% of Quartz Hill outside USFS's Direct and Indirect zones, basic hardening — gutter maintenance, ember-resistant vents — is inexpensive relative to the regional burn-probability risk noted above. Details in the home-hardening guide.
Where Quartz Hill's figures come from
Every one of the two percentiles behind Quartz Hill's 4,782-place national rank traces to USFS's Wildfire Risk to Communities dataset — see the methodology guide. The exposure-zones guide covers what Quartz Hill's dominant minimal exposure actually means, with real examples from across the dataset.
