Lehi, UT Fire Regulations: Wildfire Zones (2026)

Lehi City Code section 10-2-1(E) adopts the 2018 International Wildland-Urban Interface Code, published by the International Code Council with Appendices A through H, as the city's Wildland-Urban Interface Code, and it amends four sections of that model code. 1 inserts "Lehi City" as the jurisdiction name. 7 sets the criminal classification for a violation at class B misdemeanor. 00. 1 requires an approved automatic sprinkler system, installed to nationally recognized standards, in every new building that must meet Class 1 or Class 2 ignition-resistant construction under Chapter 5 of the code throughout the Dry Creek Corridor, Lehi's mapped wildland-urban interface area.

These amendments were adopted by Ordinance 11-2017 on March 24, 2017, layered onto the base construction-code adoption ordinance, Ordinance 42-2014 of December 8, 2014. Under section 10-2-3 the Fire Marshal is the authority having jurisdiction (AHJ) for the Wildland-Urban Interface Code specifically, distinct from the Assistant Building Official who administers the Building, Residential, Plumbing, Mechanical and Energy Conservation codes. A property owner who believes strict application of a WUI Code requirement is impractical must apply to the Fire Marshal in writing, stating the reason compliance is impractical, the requested modification, and why the modification still meets the intent of the code without lessening fire-safety protection; the Fire Marshal must issue a written decision within thirty days.
