Centennial, CO Noise Ordinances: Construction Hours (2026)

Centennial Municipal Code § 12-7-401 opens by stating its purpose: the restriction exists in order to control noise levels. The rule has a distance test and a time test, and both must be met before it applies.

The distance test is 300 feet. The section reaches construction activities within 300 feet of residential uses, so what matters is how close the work is to a place where people live. Work farther than 300 feet from residential uses is not restricted by this section. The text speaks of residential uses instead of naming particular zoning districts, so the question on any Centennial job site is whether a residential use sits inside that 300 foot distance.

The time test runs from 7:00 p.m. to 7:00 a.m. Inside that window, covered construction activities shall not take place. The wording is mandatory. The quoted text does not set a decibel reading or ask whether a neighbor was actually disturbed. The activity itself is what is barred during those hours. The quoted text also draws no distinction between weekdays and weekends, so the 7:00 p.m. stop and the 7:00 a.m. start are the only hours it states.

The section then gives the Director authority to make exceptions. The Director may authorize construction activities during the hours of 7:00 p.m. to 7:00 a.m. for good cause shown. The code writes examples into the text: minimizing peak hour traffic disruptions and performing emergency repairs. The phrase including, but not limited to, means those examples do not close the list, and other reasons can qualify if good cause is shown. Because the Director may authorize and is not required to, approval is discretionary, and the party that wants night work carries the job of showing the cause.

The provision sits in the Land Development Code's Environmental Quality division, alongside separate ground-vibration standards for adjoining zoning districts. A contractor working near Centennial homes who needs to work in the evening or before 7:00 a.m. should have the Director's authorization in hand first.
