Greeley's Noise Ordinances: The Rules That Matter

Every city handles noise ordinances a little differently. In Greeley, Colorado, there are 6 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Amplified Music & Outdoor Sound

Greeley requires a police-chief permit to install or operate loudspeakers or sound-amplifying equipment, and limits operation to 7:00 a.m.-10:00 p.m., narrowing on Sundays and holidays for commercial use.

Key details: Operating hours: 7:00 a.m.–10:00 p.m. daily. Sun/holiday commercial: 10:00 a.m.–4:00 p.m. only. Residential districts: police permit required for any use. Minimum fine: $1,000 (partly suspendable).

A first §12-360 violation is a misdemeanor with a minimum $1,000 fine (up to $750 of which may be suspended for city training and 15 hours of community service); a repeat offense within 365 days reinstates the full fine under §12-362.

Compared to other cities, Greeley takes a harder line on amplified music & outdoor sound. The enforcement and penalty structure reflects that.

Decibel Limits

Businesses in Greeley's commercial or industrial zones must obtain a police-issued permit before using any loudspeaker or amplified sound equipment for announcements, advertising or music.

Key details: Permit required: Before any amplified sound in these zones. Issuing authority: Chief of police or designee. Standard hours: 7 a.m. to 10 p.m.. Sunday commercial use: 10 a.m. to 4 p.m. only.

Operating amplified sound equipment in a commercial or industrial district without the required permit is a Code violation punishable under Title 1's general penalty provisions, distinct from the harsher § 12-362 fines that apply specifically to § 12-360 hours/audibility violations.

Compared to other cities, Greeley takes a harder line on decibel limits. The enforcement and penalty structure reflects that.

Quiet Hours

Greeley bars operating radios, TVs, stereos or other sound-reproduction devices between 10:00 p.m. and 7:00 a.m. if the sound is plainly audible at the property line or through party walls.

Key details: Quiet hours: 10:00 p.m.–7:00 a.m. daily. Legal test: plainly audible at property line/party wall. Vehicle stereos: barred if audible 50 ft, any hour. Penalty class: misdemeanor infraction.

A violation of §12-329 is a misdemeanor infraction, punishable under Title 1, Chapter 9 of the Municipal Code; Greeley Police respond to complaints and can cite on the plainly-audible standard alone, without a decibel meter.

Vehicle Noise

Greeley requires every registered motor vehicle to run a maintained, unmodified muffler at all times, banning cut-off or bypass devices and any exhaust change that amplifies noise beyond what the original factory muffler produced.

Key details: Applies to: all registered motor vehicles. Prohibited: cut-off/bypass exhaust devices. Also prohibited: mods that amplify exhaust noise. Code section: Greeley Municipal Code § 16-58.

Driving with a cut-out, bypassed, straight-piped, or otherwise modified exhaust that's louder than the factory setup is a traffic offense Greeley police can cite under § 16-58, whether or not the loudness is measured in decibels.

Construction Hours

Greeley's noise code exempts only the city's own emergency construction and street repair from noise limits: private contractors' equipment stays subject to the general unlawful-noise standard at any hour.

Key details: Governing sections: Greeley Municipal Code §§ 12-325, 12-326. General standard: No fixed decibel limit, nuisance-based. Construction exemption scope: City's own emergency work only. Private contractors: No blanket hours exemption.

Noise from construction equipment that annoys or disturbs a reasonable person violates Sec. 12-325 and is punishable as a misdemeanor infraction under Title 1, Chapter 9.

Barking Dogs

Greeley limits how long a pet can bark, howl, or make loud noise audible off the property: no more than ten minutes by day, five minutes at night, or 90 minutes total in 24 hours.

Key details: Legal basis: Greeley Municipal Code § 10-57. Daytime limit: 10 consecutive minutes (7a–9p). Nighttime limit: 5 consecutive minutes (9:01p–6:59a). Daily cap: 90 cumulative minutes per 24 hrs. Penalty: Misdemeanor infraction.

Exceeding the daytime, nighttime, or cumulative noise thresholds in § 10-57(a) is a misdemeanor infraction; each finding can be separately cited.
