Grant County, WI Public Conduct: Loud Party Ordinance (2026)

Grant County does not have a stand-alone loud party ordinance. Two Chapter 206 provisions do the work, and § 206-16.2, "Nuisance properties," puts the burden on the person who controls the building. It applies to anyone who resides at, maintains, leases, owns, rents or otherwise occupies any residence, business, dwelling or other building where listed nuisances are allowed to occur. The first trigger is call volume: three or more calls for law enforcement service for nuisance activities on separate days in one month, or six or more calls in a twelve-month period.

The nuisance activities include an act of harassment under § 947.013, Wis. Stats.; disorderly conduct, as defined in § 947.01, Wis. Stats.; battery; indecent conduct; prostitution; controlled substance offenses under Ch. 961; gambling; illegal discharge of a firearm under § 941.20; and any other offense against public peace and order as defined in the Code. The count applies whether or not a citation or arrest was made for the violation, and it reaches property owners, operators, tenants, occupants or persons associated with a property.

The second trigger is host-style liability for underage drinking. Subsection B prohibits, notwithstanding Chapter 125 of the Wisconsin Statutes, allowing a property or place to be used for the purpose of facilitating the consumption of alcohol beverages by underage persons. Section 206-14A(3) separately says no adult may knowingly permit or fail to take action to prevent the illegal consumption of alcoholic beverages by an underage person on premises owned by the adult or under the adult's control.

The noise itself is handled by § 206-1, which prohibits "unreasonably loud" conduct in a public or private place when it tends to cause or provoke a disturbance. Section 206-16.3 protects the other side: a caller is not found in violation if the call reports a violation substantiated by responding law enforcement. These rules apply in unincorporated Grant County; cities and villages have their own codes.
