Height Limits

City of Mosinee Code Sec. 42-788 caps fences, walls, hedges, and shrubbery at 6 feet above ground level in residential areas. Corner side yards are limited to 3 feet, and an 8-foot maximum applies along lot lines adjacent to nonresidentially zoned property. Front yard fences must be decorative only, no more than 50% opaque, and capped at 4 feet (decorative post caps may add up to 12 inches). A 3-foot vision-clearance limit applies within 25 feet of any street intersection. Building permits are required for fences.

Building or maintaining a fence in excess of Sec. 42-788 height limits, without the required building permit, or in violation of setback, vision-triangle, or front-yard opacity rules can trigger municipal forfeitures and an order to remove or modify the fence. Enforcement is handled through the City Clerk and Building Inspection Services; unresolved violations are processed through Marathon County Circuit Court.
