Minneapolis, MN Landscaping Rules: Weed Ordinances (2026)

Weed enforcement in Minneapolis is built on two layers. First, local Code Chapter 227 bans any turf or weed growth over 8 inches on private property. Second, Minnesota Statutes 18.76 through 18.91, the Noxious Weed Law, designates four categories of noxious weeds with mandatory control or eradication. Prohibited eradicate species (such as oriental bittersweet, Japanese knotweed in some counties, grecian foxglove) must be eliminated. Prohibited control species (Canada thistle, leafy spurge, wild parsnip, common tansy, plumeless thistle, bull thistle) must be managed to prevent spread and seed production. Restricted species (buckthorn, non-native honeysuckle) cannot be sold or planted but need not be removed from existing properties. County Agricultural Inspector and city Regulatory Services coordinate enforcement and can enter property and control weeds at the owner expense if notices are ignored. Minneapolis also operates a buckthorn removal and education program through MPRB. Chemical applicators must be licensed under Minnesota Statute 18B if used commercially.
