Appleton, WI Fence Regulations: Height Limits (2026)

Sec. 23-44(a)(1)a sets Appleton's core fence-height rule: a boundary fence or wall "shall not be more than six (6) feet in height in residential districts and not more than twelve (12) feet in commercial and industrial districts," with hedges exempt from any height cap and allowed to grow to their natural height. Between the front yard setback line and the abutting lot lines, no boundary fence, wall, hedge or row planting can exceed 3 feet, regardless of the 6- or 12-foot district limit, unless another provision of the chapter states otherwise. Fence height is measured at grade, though the Inspections Supervisor may allow measuring from 2 inches above grade for drainage, and berms cannot be used to artificially raise the grade under a fence. Posts and post caps may project up to 4 inches above the otherwise-allowed height.

Two other height rules layer on top of the 6-foot residential cap. A sound-barrier fence or wall along an arterial or collector street can rise to 8 feet on a double-frontage lot or 6 feet on a corner lot, except within the vision corner. Along a freeway, a sound-barrier fence, wall or berm combination can reach 20 feet, measured from the freeway's own grade, and any such fence over 8 feet needs engineered plans from a state-certified engineer or architect. Corner lots carry an additional constraint under Sec. 23-50(g): where a district requires a 20-foot street setback, a vision corner triangle runs between points 25 feet from the intersecting right-of-way lines, and any fence, wall or sign inside that triangle is capped at 3 feet, with plantings kept clear of the 3-to-10-foot sightline band.
