Utah: Wildfire Code, Grants & Insurance

Last verified 2026-06-11 · Methodology · Changelog

Statewide, phasing in

Utah's HB 48 (2025), effective January 1, 2026, requires cities and counties with mapped wildland-urban interface areas to adopt and enforce fire-safety building and landscaping standards. The International Wildland-Urban Interface Code is adopted within the State Construction Code, with WUI areas mapped by local fire marshals or the authority having jurisdiction. Implementation is phasing in: per-structure fee provisions run on a 2026 to 2028 schedule, and local adoption status varies by jurisdiction while the framework rolls out. This page tracks adoption as it happens.

Defensible space law

Utah has no standalone statewide defensible space statute applying directly to existing homes. Defensible space and landscaping standards arrive through HB 48's required local adoption of WUI fire-safety standards, applied in mapped WUI areas by local jurisdictions.
