Full Breakdown
Centennial Municipal Code § 12-7-401 sets nighttime construction-noise hours: construction activity within 300 feet of residential uses cannot occur between 7:00 p.m. and 7:00 a.m. The rule sits in the Land Development Code's Environmental Quality division, alongside separate ground-vibration standards for adjoining zoning districts. The Director may authorize work during the restricted hours for good cause shown, including minimizing peak-hour traffic disruption or performing emergency repairs, so contractors working near homes need Director authorization to work evenings or before 7 a.m.
Violations & Fines
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.
