Waukesha, WI Noise from Specific Sources: Bar & Nightclub Noise (2026)

Municipal Code § 9.11, General Rules and Regulations for alcohol beverage licensees, lists UNREASONABLE NOISE among the standing conditions every Class A and Class B liquor license carries in the City of Waukesha. The section states plainly that unreasonably loud noise or other conduct which tends to cause a public disturbance or unreasonably interferes with the quiet enjoyment of the surrounding neighborhood is prohibited on or about a licensed premises. The same section requires orderly operation at all times and bars disorderly, riotous or indecent conduct on or about any licensed premises, so a bar or nightclub that lets amplified music, crowd noise, or fights spill onto the street is exposed on two fronts at once.

Enforcement runs through the Waukesha Police Department, which has standing authority under § 9.11's consent-to-inspection clause to enter licensed premises without a warrant during reasonable hours to investigate violations, and through the Ordinance and License Committee, which under § 9.14 can suspend, revoke, or refuse to renew a liquor license for chapter violations after a hearing under Wis. Stat. § 125.12(2) and (3). A revoked license cannot be reissued for the same premises for at least 60 days, and the same person cannot hold a new license for 12 months. Because noise-related disorder is a chapter violation rather than a standalone forfeiture offense, § 9.18 routes the monetary penalty to Municipal Code § 25.05: a first offense carries a forfeiture of not less than $10 nor more than $2,500, and any subsequent offense runs $100 to $5,000, plus court costs, with each day a violation continues counted as a separate offense.
