Properties in Boise's wildland-urban interface, including the Foothills and the Bench rim, must maintain defensible space by clearing combustible vegetation within 30 feet of structures under Boise Fire's WUI program.
Boise Fire Department administers a wildland-urban interface program that recommends two zones: an immediate five-foot non-combustible zone and an intermediate 5-to-30-foot lean-clean-and-green zone. The 2023 zoning rewrite added Foothills overlay standards requiring fire-resistant landscaping and access for new subdivisions above the 25-degree slope line. Annual inspections are advisory, not punitive, but insurance carriers increasingly condition coverage on compliance. Larger fuel-reduction projects in the Boise Foothills Conservation easement are coordinated with the Land Trust of the Treasure Valley.
Non-compliance is generally addressed through education and follow-up inspection. Repeated failure to maintain defensible space on developed lots can become a property-maintenance nuisance citation.
