Plymouth, MN Public Conduct: Loud Party Ordinance (2026)

03, Subd. 7, part of the Noise chapter (Section 2025) enacted by Ordinance 2012-13, treats a loud party as a shared offense rather than only the host's problem. Anyone who participates in a gathering that gives rise to noise unreasonably disturbing another person's peace, quiet or repose is in violation, not just whoever is playing music or hosting. Once a Plymouth Police Department officer on scene determines the gathering is creating a noise disturbance, the officer has authority to order everyone present, except the property's owner or tenant, to disperse immediately, and anyone who refuses to leave after that order commits a separate violation.

The owner or tenant does not escape responsibility by staying: the ordinance requires them, once they know of the disturbance, to make every reasonable effort to stop it, which can support a citation against the host even if they are not ordered to disperse themselves. The provision sits next to the Section's related nighttime rule in Subd. as prima facie evidence of a violation, giving officers two overlapping tools for the same late-night gathering. 17: officers can pursue a citation for the misdemeanor of violating the noise ordinance, punishable by the maximum fine Minnesota law allows for misdemeanor offenses, with each day of a continuing disturbance a separate violation, and the City can additionally seek an injunction or abatement order under Subd. 2 of that same section.
