Commerce City, CO Public Conduct: Loud Party Ordinance (2026)

Section 12-5010 of the Commerce City Revised Municipal Code, adopted by Ord. No. 1848 on January 10, 2011, holds the person with possessory control of a premises, whether owner, tenant, occupant, or someone jointly controlling the property, liable for hosting, sponsoring, conducting, or permitting a social gathering that becomes a public nuisance, so long as the nuisance was either intended or reasonably foreseeable to that host. The Code spells out a specific automatic trigger: a gathering is deemed a public nuisance if an open keg of beer sits in a yard adjacent to a street, on a front porch visible to the public, or in a side yard visible to neighbors or people on public streets and sidewalks.

Beyond the keg rule, section 12-5010(b) separately lists sixteen offenses, including disorderly conduct, open containers, unreasonable noise, trespass, littering, and disturbing the peace, that also convert a party into a nuisance if they occur at the gathering or spill onto neighboring property. Once a Commerce City peace officer declares the gathering a public nuisance, the officer may order everyone not domiciled at the address to disperse immediately, and failing to obey that dispersal order is its own separate violation of the section, independent of whatever underlying conduct triggered the nuisance finding in the first place.

That structure gives police two charging options at one loud party: the host for permitting the nuisance, and any guest who refuses to leave once ordered out. Commerce City Police typically respond to loud-party complaints from neighbors in residential subdivisions across the city, including Reunion and the Northern Range, and the host's liability attaches even without proof the host was the one making noise or drinking, since the standard is possessory control plus a reasonably anticipated result.
