Summary

St. Louis makes it a misdemeanor to disturb the peace with noisy, riotous, or disorderly conduct, and separately holds an owner or occupant liable for permitting such disturbances on premises they control.

Any person who shall disturb the peace of others by noisy, riotous or disorderly conduct, or by violent, tumultuous, offensive or obstreperous conduct or carriage, or by loud and unusual noises... or any person who, in the City, shall permit any such conduct in or upon any house or premises owned or possessed by him or under his management or control, so that others in the vicinity are disturbed thereby, shall be guilty of a misdemeanor.

Full Breakdown

City Code Section 15.46.030 bans disturbing the peace of others through noisy, riotous, disorderly, tumultuous, or offensive conduct, loud and unusual noises, or offensive language calculated to provoke a breach of the peace, in any public place. It also separately criminalizes permitting such conduct: any person who allows noisy or disorderly conduct on a house or premises they own, possess, manage, or control, so that neighbors nearby are disturbed, is guilty of a misdemeanor -- the code's host-liability clause for loud parties. No fine is set in this section, so the citywide general penalty at Section 1.12.010 controls.

Violations & Fines

Guilty of a misdemeanor under the citywide general penalty, Section 1.12.010: a fine of $1 to $500, up to 90 days in jail, or both -- each day of ongoing disturbance is a separate offense.

Frequently Asked Questions

What's the penalty for disturbing the peace in St. Louis?
No fine is set in Section 15.46.030 itself, so the citywide general penalty applies: $1 to $500, up to 90 days in jail, or both.
