Ontario, OH
Ontario, OH's wildfire risk, in USFS's own numbers
Out of every US place USFS scores, Ontario lands at the 32nd percentile for wildfire risk to structures — close to the middle of USFS's national wildfire-risk range — a figure built from its 3,169 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Ontario at the 31st percentile, close to its 32nd-percentile risk score.
Ontario's building exposure, zone by zone
Of Ontario's 3,169 counted buildings, 50.5% carry Direct exposure and only 46% carry Minimal — a lopsided split that puts defensible-space clearing ahead of vents or roofing as the intervention worth doing first.
Where Ontario ranks
Within Ohio, Ontario ranks higher (71st percentile) than it does nationally (32nd) — one of the more fire-exposed places in a state that, overall, scores lower than that. Among the 31,521 US communities USFS scores, Ontario ranks 21,404 for wildfire risk (1 is highest) and 5,204 by building count (1 is largest). Within Ohio alone, it ranks 377 of 1,264 places by risk. See the full county-by-county picture for Ohio on its state page.
Shopping for coverage in Ontario
Ontario's moderate wildfire rating (32nd 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.
What would actually reduce this score
With 50.5% of Ontario in Direct exposure, defensible-space clearing and ember-resistant construction (vents, Class-A roofing) address the exposure this page's own numbers describe, not a generic checklist. See the home-hardening guide.
