Summary
Commerce City has no fixed nighttime curfew hours for noise; instead Municipal Code Section 6-2011(b) bans unreasonable noise at any hour, on any premises or in any vehicle. Section 6-2011(a) lists the time of day as one factor city agents weigh when deciding whether a sound is unreasonable, so late-night noise is judged more strictly than the same sound at midday, without a set clock cutoff.
(a)Unreasonable noise defined. Any sound of such level and duration as to be or tend to be injurious to human health or welfare, or that would unreasonably interfere with the enjoyment of life or property, is deemed unreasonable. City agents are authorized to make a prima facie determination as to whether a noise is unreasonable, which determination may be based upon, but need not be limited to, a consideration of the following factors:(1)The time of day; ... (b)Unreasonable noise prohibited. It shall be unlawful to make, continue or cause to be made or continued any unreasonable noise and no person shall knowingly permit such noise upon any premises or in or upon any vehicle owned or possessed by such person or under such person's control or operation. For purposes of this section, proof that the owner or occupant of the premises upon which the unreasonable noise occurred was present at the time of the violation shall constitute prima facie evidence that such person was in control of the premises and knowingly permitted the violation to occur.
Full Breakdown
Commerce City does not set specific overnight quiet hours with fixed start and end times. Instead, Section 6-2011(a) of the Commerce City Revised Municipal Code defines unreasonable noise as any sound of a level and duration that is or tends to be injurious to human health or welfare, or that unreasonably interferes with the enjoyment of life or property, and directs city agents to weigh the time of day as one of several factors, alongside the size of any gathering, the neighborhood, and the presence of amplification equipment, in making a prima facie finding. Section 6-2011(b) then makes it unlawful to make, continue, or knowingly permit any unreasonable noise on a premises or in a vehicle a person owns, possesses or controls, at any hour of the day or night; an owner or occupant present when the noise occurred is presumed to have known about it and permitted it to continue.
Violations & Fines
Making or knowingly permitting unreasonable noise at any hour violates Section 6-2011(b) and is a civil infraction under Section 6-1003, proven by a preponderance of the evidence in Commerce City Municipal Court. Night hours weigh more heavily toward an unreasonableness finding under the time-of-day factor in Section 6-2011(a). Presence on the premises when the noise occurred is prima facie evidence of knowing permission. The Code's general fine under Section 1-5 otherwise applies.
