Iron County, UT Landscaping Rules: Weed Ordinances (2026)

Section 8.20.050, titled Noxious Weeds, declares that any violation by a responsible person of the Utah Noxious Weed Act, U.C.A. Section 4-17-1 et seq., or any successive state regulation of noxious weeds, is unlawful and constitutes a county nuisance. The section designates the county weed control board, or its designee, as the enforcement officer for weed violations rather than the zoning officer or sheriff who handle other Chapter 8.20 nuisances. A parallel provision in the zoning title, Section 17.36.220, similarly requires all property owners to comply with the Utah Noxious Weeds Act and any successive state regulation.

Because Section 8.20.050 folds weed violations into the general nuisance chapter, the same procedural protections and penalties apply: a written notice to abate under Section 8.20.110 giving thirty days to correct the weed condition, an optional voluntary correction agreement under Section 8.20.120, and, if uncorrected, an administrative citation under Section 8.20.140 carrying a fine under Section 8.20.160 capped at $100 per week under a voluntary agreement or $200 per week under an administrative citation. The county may also abate the weeds itself under Section 8.20.150 and recover the cost as a lien against the property under Section 8.20.150(E).

A responsible person who continues to allow noxious weeds after notice also risks a Class B misdemeanor charge under Section 8.20.130, carrying a fine up to $1,000 and up to six months in jail, with each day a separate offense, and may appeal an administrative citation to the county hearing officer within thirty days under Section 8.20.200.
