Ashwaubenon, WI Fence Regulations: Height Limits (2026)

Ashwaubenon Municipal Code Sec. 5-8-758, Maximum Height, in Article 8 of Chapter 5 sets three tiers of fence height. In residential areas, a fence may run six feet high along the rear lot line and along the side lot line from the rear of the lot up to the front setback line, but drops to three feet from the building setback line to the front property line, and corner lots are also capped at three feet within the setback. Commercial and industrial property may run fences up to ten feet on all sides, except within sight triangles, where the cap drops to three feet.

Where commercial or industrial property is adjacent to residential property, the fence is capped at eight feet. Sec. 5-8-761, Vision Triangle, layers a separate, stricter limit on top of the height chart wherever a fence sits near a street intersection: within the vision triangle, defined by lines running 35 feet back from the intersection along each street curbline, no bush, shrub, tree or opaque object over 30 inches above sidewalk or curb grade is allowed, and a fence in that triangle is limited to 30 inches unless it is of see-through design with at least 90 percent visibility, and even then it cannot interfere with drivers' sightlines.

Sec. 5-8-757 additionally bars sharp or pointed pickets dangerous to life or limb regardless of height, and Sec. 5-8-760 sets a minimum one-half-inch flat top on picket fences. Sec. 5-8-765 makes any fence that predates the ordinance and does not conform stay grandfathered unless it is altered, enlarged or replaced, at which point the entire fence must be brought into compliance.
