Summary
Fort Collins Municipal Code Section 17-129 bans making or knowingly permitting unreasonable noise, and directs Police Services to weigh whether amplification equipment was used when deciding if a sound crossed the line. It works alongside, not instead of, the numeric decibel limits in Chapter 20.
(a)No person shall make, continue or cause to be made or continued any unreasonable noise; and no person shall knowingly permit such noise upon any premises owned or possessed by such person or under such person's control.(b)For purposes of this Section, unreasonable noise shall mean any sound of such level and duration as to be or tend to be injurious to human health or welfare, or which would unreasonably interfere with the enjoyment of life or property, but excludes all aspects of the employer-employee relationship concerning health and safety hazards within the confines of a place of employment. Members of Police Services are empowered 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;(2)The size of any gathering of persons creating or contributing to the noise;(3)The presence or absence of noise amplification equipment; and(4)Any other factors tending to show the magnitude and/or disruptive effect of the noise.

Full Breakdown
Section 17-129(a) prohibits making, continuing or causing unreasonable noise, and separately bars a property owner or occupant from knowingly permitting such noise on premises under their control. Subsection (b) defines unreasonable noise as any sound of a level and duration injurious to health or welfare, or that unreasonably interferes with the enjoyment of life or property, excluding workplace employer-employee safety matters. Police Services officers make the prima facie call using four factors: the time of day, the size of the gathering creating the noise, the presence or absence of noise amplification equipment, and any other factor showing the noise's magnitude or disruptive effect, which means a party running speakers or a PA system is evaluated more strictly than one without.
Subsection (c) makes an owner or tenant's presence at the time of the violation prima facie evidence they controlled the premises and knowingly permitted it. This subjective standard is a separate enforcement track from the objective zone-based decibel limits in Section 20-23 of Chapter 20: an amplified party can be cited under Section 17-129 based on amplification and disruption alone, without a Code Compliance Inspector taking a sound-meter reading, and can also be independently cited for exceeding the zone's numeric dB(A) limit under Section 20-23.
Violations & Fines
A first violation of Section 17-129 is a petty offense under Section 1-15(h), while a second or subsequent violation within twelve months escalates to a misdemeanor with fine or jail exposure under Section 1-15(a). Fort Collins Police Services issue citations based on the four statutory factors, and repeat offenders at the same address face the higher misdemeanor penalty regardless of who is present at the second incident.
