Mosinee, WI Public Conduct: Public Urination (2026)

Sec. 54-3 of the Mosinee Code of Ordinances, carried forward from the 1986 Code at § 9-2-9(c), makes it unlawful for any person to defecate or urinate, outside of designated sanitary facilities, on a broad list of locations: any sidewalk, street, alley, public parking lot, park, playground, cemetery or other public area within the city. The section extends beyond city-owned ground in two directions. First, it reaches private property when the act happens in open view of the public, so a fenced backyard is treated differently from a front lawn visible from the street.

Second, it covers the halls, stairways or elevators of public or commercial buildings, meaning apartment common areas, office buildings and retail stores fall inside the ban even though they are privately owned. The same sentence separately makes it unlawful to indecently expose one's person, a related but distinct offense that does not require public urination or defecation to have occurred. The section sits in article I of chapter 54, the general offenses article, alongside possession-of-controlled-substances and failure-to-obey-a-lawful-order provisions, and like those sections it is enforced by the police department through the municipal citation process rather than through the building inspector's maintenance-order track used elsewhere in the code.
