Summary
Mosinee caps most fences, walls, hedges and shrubbery at six feet, drops that to three feet in a corner side yard and within 25 feet of a street intersection, and allows up to eight feet where a residential lot line borders nonresidential property, all under § 42-788(c).
(1)Except as provided in section 42-710, a fence, wall, hedge or shrubbery may be erected, placed, maintained or grown on property in accordance with the location provisions of this section to a height not exceeding six feet above the ground level, except that no such fence, wall, hedge or shrubbery which is located in a corner side yard shall exceed a height of three feet. Where such lot line is adjacent to nonresidentially zoned property, there shall be an eight foot limit on the height of a fence, wall, hedge or shrubbery along such lot line.(2)No fence, wall, hedge or shrubbery shall be erected, placed, maintained or grown along a lot line on any nonresidentially zoned property, adjacent to residentially zoned property, to a height exceeding eight feet.(3)In any residence district no fence, wall, hedge or shrubbery shall be erected, constructed, maintained or grown to a height exceeding three feet above the street grade nearest thereto, within 25 feet of the intersection of any street lines or of street lines projected.
Full Breakdown
Section 42-788 defines "fence" broadly, in subsection (a), to include vegetation such as hedges and shrubbery alongside wood, stone or metal barriers, so every height rule below applies equally to a grown hedge line. Subsection (c)(1) sets the general rule: a fence, wall, hedge or shrubbery can rise to six feet above ground level, except that one located in a corner side yard is capped at three feet, and one running along a lot line adjacent to nonresidentially zoned property gets an eight-foot limit instead.
Subsection (c)(2) states the mirror rule from the other side of that same lot line: a fence on nonresidentially zoned property next to a residential district also tops out at eight feet. Subsection (c)(3) creates a corner-visibility standard that functions like a sight triangle: in any residence district, no fence, wall, hedge or shrubbery within 25 feet of the intersection of any street lines, or their projection, can exceed three feet above the nearest street grade, keeping intersections clear for drivers regardless of which yard the fence sits in.
These height limits are separate from the boundary-fence setback rules in subsection (b), which govern how far a fence sits from the property line rather than how tall it stands, and the whole section is subject to an exception carved out in § 42-710 for a use not covered here.
Violations & Fines
An oversized fence is a zoning violation under § 42-67. The common council, zoning administrator, plan commission, or a specifically damaged property owner may sue to enjoin the violation or have the fence removed; after 30 days of noncompliance with a written order, the city can pursue legal action, and a conviction carries a forfeiture with a $100 statutory minimum plus any additional penalty under § 1-13.
