Construction hours in Aurora, CO — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Aurora restricts construction to 7 AM-6 PM on weekdays and 12 PM-6 PM on weekends. Special permits may be issued for after-hours work in cases of urgent necessity or when public health and safety would not be impaired.
Aurora's noise ordinance limits construction activities — including erection, excavation, demolition, alteration, or repair of buildings — to 7 AM to 6 PM on weekdays and 12 PM to 6 PM on Saturdays and Sundays. During permitted hours (7 AM-5 PM weekdays), construction crews may use machinery at industrial sound levels. The Code Enforcement Officer may grant permits for work between 6 PM and 7 AM in cases of urgent necessity in the interest of public health and safety, for a period not exceeding three days.
