North Tustin, CA
How exposed is North Tustin to wildfire?
North Tustin sits at the 84th percentile nationally for wildfire risk to structures — in USFS's highest wildfire-risk band nationally — per USFS's Wildfire Risk to Communities model, built from its 10,220 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, North Tustin's burn probability — fire likelihood with no building count factored in — sits at the 86th percentile nationally.
Where North Tustin's buildings actually sit
USFS classifies 90.8% of North Tustin's buildings as Minimal exposure, the largest of the three zones here by a wide margin over 4% Direct and 5.2% Indirect — a landscape-level risk rather than a building-by-building one. At 10,220 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
How North Tustin compares
North Tustin's 84th national percentile looks worse in isolation than its 48th ranking inside California does — this place is on the milder end for its own state, by 37 points. Among the 31,521 US communities USFS scores, North Tustin ranks 5,007 for wildfire risk (1 is highest) and 1,573 by building count (1 is largest). Within California alone, it ranks 823 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Shopping for coverage in North Tustin
North Tustin 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 84th-percentile score like North Tustin's can end up mattering for.

With 90.8% of buildings rated Minimal exposure, North Tustin gets less benefit from structure hardening than a Direct- or Indirect-dominant place would — the home-hardening guide explains why the zone matters.
More on how this number was built
North Tustin's 84th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what minimal exposure implies beyond North Tustin, see the exposure-zones guide.
