Woodbury, MN Landscaping Rules: Weed Ordinances (2026)

Weeds in Woodbury are regulated two ways. First, weeds and grasses over eight inches are a property-maintenance nuisance, the same height standard applied to lawns. Second, the Common Code Violations page states that properties must control or eradicate noxious weeds 'as defined by state statute,' citing Canada thistle as a common example. Minnesota's Noxious Weed Law (Minn. Stat. 18.78) requires any owner or occupant of land to control all noxious weeds, in the categories listed under Minn. Stat. 18.771, in the manner and time ordered by an inspector; if an owner refuses, the city or county may do the work and charge the cost back to the property, or refer the owner to district court. Woodbury's eight-inch nuisance limit contains a managed-landscape exemption: native gardens and water-saving plantings may exceed eight inches if weeds are only a minor portion. Minnesota Statute 412.925 reinforces this, allowing managed natural landscapes that exceed eight inches and have gone to seed, but those plantings 'may not include any noxious weeds and must be maintained.' So even an exempt native planting must keep noxious weeds out.
