Loveland, CO Landscaping Rules: Weed Ordinances (2026)

020(A) makes it unlawful for the owner of any property, lot, block or parcel of land in the city to allow noxious weeds required to be eradicated under the state Weed Act to grow at any height, or to let weeds other than noxious weeds, or grasses, exceed eight inches. Subsection B exempts ornamental or native grasses from the eight-inch cap if they're shown on an approved landscape plan and maintained accordingly, used as a supplement within a broader landscaped area, or growing in a private or public natural area in a manner consistent with the grasses' health, including reseeding.

Subsection C gives the weed district's published management recommendations for non-eradication-required noxious weeds priority over the eight-inch rule where the two conflict. Subsection D requires that waste from cut or destroyed weeds, grasses, or marijuana plants be disposed of so the property stays clean and doesn't spread the weeds further. Subsection E creates an affirmative defense for City-owned land the Parks and Recreation Director has designated as a natural area, open lands, wildlife corridor, or wetlands, or for public or private natural areas so determined by the Development Services Director. Subsection F declares any violation a public nuisance outright, which routes enforcement through the Title 16 nuisance machinery rather than requiring a separate finding.
