Mosinee, WI Building Setbacks & Zoning: Structure Height Limits (2026)

Section 42-220 of the City of Mosinee zoning code sets building bulk limitations for the R-3 single-family residence district. For the district's core permitted use, single-family detached dwellings along with rectories, parsonages and parish houses, the table caps maximum building height at two and a half stories and not to exceed 35 feet. 80. 00 for health and medical institutions. The city's general height-and-area exceptions in Section 42-707 modify this baseline in specific circumstances: churches, schools, hospitals and similar public or quasi-public buildings may rise to 60 feet or five stories if every yard on the lot is increased by at least one foot for each foot of extra height above the district limit, and an ordinary residence may add up to ten feet of height under the same yard-expansion trade-off.

Structures such as chimneys, church spires, water towers, flagpoles and utility poles are exempted from the height rules altogether. Comparable height caps recur elsewhere in Chapter 42: the VP district caps buildings at 2½ stories or 35 feet, and R-1 and R-2 single-family districts instead tie side-yard depth to height through a footnote requiring an extra foot of side yard for every two feet a building exceeds 15 feet, rather than a flat cap. A property owner planning a two-and-a-half-story or taller home in the R-3 district should confirm the district boundary and consult Section 42-707's exceptions before assuming the 35-foot ceiling is absolute.
