Blue Springs, MO Public Conduct: Loud Party Ordinance (2026)

Section 220.567 targets the host, owner, renter or organizer of a residential gathering in the City of Blue Springs, Missouri, rather than the minors who attend. Liability attaches whether or not the responsible person is present at the premises, so long as that person knew or reasonably should have known that a minor possessed or consumed alcohol or a controlled substance there and failed to take reasonable steps to stop it. 'Open house party' covers any social gathering at a residence, motel or hotel room, apartment, condominium or hall, including its curtilage.

Three exceptions apply: a minor's lawful prescription drug use, religious observances or prescribed medical treatment, and a minor's possession of alcohol or a prescribed drug incidental to lawful employment. If a minor organizes the gathering, that minor's parents or guardians are jointly and severally liable for enforcement costs. When a Police Officer determines the gathering threatens public peace, health, safety or welfare, the Municipal Court judge may assess the City's enforcement services, meaning officer time, administrative costs and equipment repair, against the responsible person as court costs, capped at $1,000 per event and added on top of any fine. The City reserves the right to pursue any enforcement costs above that cap through separate legal action, including attorney fees.
