How Centennial Handles Noise Ordinances: A Practical Guide

Centennial maintains 86 local ordinances across all categories, and 5 of those deal specifically with noise ordinances. Here is a breakdown of what the city actually requires, what is prohibited, and where Centennial falls on the strict-to-permissive spectrum compared to other cities.

Amplified Music & Outdoor Sound

Centennial requires live music or amplified sound at a Permanent Commercial Outdoor Patio to stop by 10 p.m. whenever the patio sits within 300 unobstructed feet of a residential use, per the Land Development Code.

Key details: Curfew: 10:00 p.m. local time. Trigger distance: Within 300 unobstructed feet of homes. Screening required: 6-ft barrier within 150 ft of homes. Governing code: LDC § 12-3-812(B)(6).

Live music or amplified sound continuing past 10 p.m. on a patio within 300 unobstructed feet of a residential use violates Section 12-3-812(B)(6) and is enforceable as a Land Development Code violation against the business operator.

Barking Dogs

Centennial caps barking at ten minutes by day and five minutes at night before it becomes a code violation. Sec. 7-7-470 requires a written warning before any fine issues.

Key details: Daytime limit: 10 minutes continuous barking. Nighttime limit: 5 minutes continuous barking. Daily cap: 90 cumulative minutes/24 hours. Process: Written warning before citation. First fine: $50.

First offense $50, second within two years $75, minimum $100 after that, each with mandatory court appearance, under Sec. 7-7-170(g).

Decibel Limits

Centennial, Colorado sets no decibel meter reading for everyday noise. Section 10-12-20 bans any excessive or unusually loud noise that disturbs the peace or injures property, with fines of $100, $200 and $400 by offense. The only numeric decibel standards in the code cover new noise sensitive buildings near Centennial Airport, which must reach a 25 or 30 dB(A) reduction.

Key details: Numeric limit for general noise: None printed in Article 12 of Chapter 10. Governing standard: Excessive or unusually loud noise that disturbs or endangers others. First offense fine: Minimum $100. Second offense fine: Minimum $200. Third or later offense: Minimum $400 plus mandatory court appearance.

A violation of Article 12 is a minor offense. On conviction the fine is not more than the maximum authorized in Section 1-4-10, with a minimum of $100 for a first offense, $200 for a second offense and $400 for a third and any subsequent offense. A mandatory court appearance is required for a third or subsequent offense. Officers follow the penalty assessment procedure in Section 16-2-201, C.R.S. Under Section 10-12-50 a violation is also a public nuisance, so the City can seek summary abatement, a restraining order or an injunction.

Construction Hours

Centennial bars construction activities within 300 feet of residential uses between 7:00 p.m. and 7:00 a.m. under Municipal Code § 12-7-401. The Director may authorize work inside those hours for good cause shown, such as minimizing peak hour traffic disruptions or performing emergency repairs.

Key details: Restricted hours: 7:00 p.m. to 7:00 a.m.. Distance: within 300 feet of residential uses. Exception authority: The Director, for good cause shown. Named examples: minimizing peak hour traffic disruptions and performing emergency repairs. Stated purpose: In order to control noise levels.

Construction outside permitted hours near homes violates the LDC's noise standard; absent Director authorization for good cause, the City can require night work to stop.

Quiet Hours

Centennial bans excessive or unusually loud noise at any hour under Article 12 of Chapter 10: there's no fixed clock curfew, but noise that disturbs, annoys, or endangers others' peace or property is a punishable minor offense.

Key details: Standard: No fixed clock curfew. Prohibited: Excessive or unusually loud noise, any hour. 1st offense fine: $100 minimum. 3rd+ offense fine: $400, court required.

A first offense carries a minimum $100 fine, a second offense $200, and a third or later offense $400 with a mandatory court appearance; the City may also seek an injunction to abate a chronic noise nuisance.

The Bottom Line

Centennial's noise ordinances rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Centennial is broadly strict or permissive.
