Penngrove, CA
Penngrove wildfire risk explained
Out of every US place USFS scores, Penngrove lands at the 89th percentile for wildfire risk to structures — in USFS's highest wildfire-risk band nationally — a figure built from its 2,463 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Penngrove at the 92nd national percentile — 3 points above its risk-to-structures score, a gap driven by how much is actually built there.
Where Penngrove's buildings actually sit
Of Penngrove's 2,463 counted buildings, 77.1% carry Direct exposure and only 2.1% carry Minimal — a lopsided split that puts defensible-space clearing ahead of vents or roofing as the intervention worth doing first.
Where Penngrove ranks
Penngrove ranks lower within California (59th percentile statewide) than its 89th national percentile suggests alone — a calmer spot in a state where wildfire risk generally runs high. Among the 31,521 US communities USFS scores, Penngrove ranks 3,460 for wildfire risk (1 is highest) and 6,368 by building count (1 is largest). Within California alone, it ranks 647 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Shopping for coverage in Penngrove
Penngrove 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 89th-percentile score like Penngrove's can end up mattering for.

Lowering exposure, not just insuring around it
With 77.1% of Penngrove 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.
