Ashwaubenon, WI Landscaping Rules: Weed Ordinances (2026)

Chapter 11's noxious weeds section, Section 11-1-21(F), was written, in the Village's own words, to prohibit the uncontrolled growth of vegetation and to control noxious weeds, while permitting the planting and maintenance of planned natural landscaping. The operative height standard for developed property sits at subsection (3)(b): any parcel with improvements upon it, or a parcel less than one acre in size, must destroy noxious weeds and cut and maintain long grass and vegetation to a height of six inches or less. That six-inch ceiling applies on top of the requirement to destroy listed noxious weeds, a defined term covering plants named in Wis.

Stat. 0407(1)(b) plus burdock, thistle, ragweed, garlic mustard, buckhorn and poison ivy by name. The rule exempts cultivated gardens, agricultural land, shoreland within 35 feet of the ordinary high-water mark, environmentally sensitive areas, and planned natural landscaping kept wholly inside the lot, so a homeowner cutting back a vegetable patch or a rain garden is not in violation just because it exceeds six inches. Enforcement starts with the director of public works or a designee issuing written notice, mailed or posted on the door, giving the owner 48 hours to cut the growth.

If the 48 hours pass without compliance, the Village authorizes the work itself and bills the owner under Wis. Stat. 0627. After three notices in a calendar year on the same property, the Village stops sending further notices and simply mows and bills for every violation after that.
