Warren, MI Public Conduct: Loud Party Ordinance (2026)

Sec. 22-113 covers two related problems at residences and other premises Warren residents control. First, subsection (2) makes it unlawful for an owner or the person responsible for organizing a social or cultural event to permit noisy or riotous persons to assemble at a residence or premises, including its parking lots and surrounding open areas, to the annoyance or disturbance of the neighborhood and the public peace. Second, subsection (3) targets open house parties specifically: a social gathering with people present besides the owner, those with rights of possession, or their immediate family.

No adult with control of a residence or premises may allow such a gathering if a minor possesses or consumes alcohol or a controlled drug there, where the adult knew or reasonably should have known about it and failed to take reasonable steps to prevent it. Subsection (4) exempts legally protected religious observances and educational activities from the open-house-party rule. Subsection (5) sets a two-tier penalty: a first violation carries a fine of up to $500 and/or up to thirty days in the county jail, and any subsequent violation raises the possible jail term to up to ninety days, keeping the $500 fine cap.

The section defines residence or premises broadly, covering a motel or hotel room, house, apartment, condominium, or other dwelling unit and its curtilage, or a hall, meeting room, or other assembly space, whether occupied temporarily or permanently and regardless of whether it is rented, owned, or used for free.
