Clarendon Hills, IL
Clarendon Hills wildfire risk explained
Out of every US place USFS scores, Clarendon Hills lands at the 22nd percentile for wildfire risk to structures — close to the middle of USFS's national wildfire-risk range — a figure built from its 3,194 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Clarendon Hills at the 25th national percentile — 4 points above its risk-to-structures score, a gap driven by how much is actually built there.
Where Clarendon Hills's buildings actually sit
USFS classifies 97.1% of Clarendon Hills's buildings as Minimal exposure, the largest of the three zones here by a wide margin over 2.9% Direct and 0% Indirect — a landscape-level risk rather than a building-by-building one.
Clarendon Hills against the rest of the country
Compare Clarendon Hills's two percentiles: 65th within Illinois, only 22nd nationally — a gap of 43 points that marks it as unusually exposed for its own state. Among the 31,521 US communities USFS scores, Clarendon Hills ranks 24,698 for wildfire risk (1 is highest) and 5,172 by building count (1 is largest). Within Illinois alone, it ranks 507 of 1,445 places by risk. See the full county-by-county picture for Illinois on its state page.
Clarendon Hills and the insurance market
Clarendon Hills's moderate wildfire rating (22nd percentile) isn't the kind of score driving the carrier pullback making news in the highest-risk Western markets — but a standard homeowners quote is still worth comparing on its own terms.
Hardening a home in Clarendon Hills
Even with 97.1% of Clarendon Hills 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.
