Full Breakdown
The Town restricts construction, drilling and demolition noise under Castle Rock Municipal Code section 9.16.030(5). Operating tools or equipment for construction between the prohibited hours is a noise disturbance when the sound crosses a residential property boundary. Weekday quiet hours are 7 p.m. to 7 a.m.; on weekends and holidays the window widens to 6 p.m. to 8 a.m. Exceptions exist for equipment delivery or pickup, emergency work, and work exempted under section 9.16.050 or approved by variance. These are Castle Rock's own rules, not Douglas County's, because Castle Rock is a home-rule municipality that sets construction hours directly.
Violations & Fines
Violations are enforced by Code Compliance and Police; report through Report a Concern or non-emergency 303-663-6100. Municipal-code convictions carry fines under the Town's general penalty provisions.
