Construction hours in Auburn, WA — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Auburn allows construction 7 AM to 10 PM weekdays and Saturdays, and 9 AM to 10 PM Sundays, under ACC 8.28.010. Outside hours, equipment and hammering are a public disturbance.
Under ACC 8.28.010, sounds created by construction activity including equipment, power tools, and hammering are defined as public disturbance noise when they occur before 7 AM or after 10 PM on weekdays (Monday through Saturday), or before 9 AM or after 10 PM on Sundays. Inside that permitted window, construction noise is generally exempt from the WAC 173-60 decibel limits so long as the work is a legitimate temporary construction, maintenance, or repair project. Emergency utility repairs and public works emergencies are exempt from the time limits. Large projects in the Auburn Valley industrial corridor, the A Street SE corridor, and the Boeing Auburn plant area are subject to additional noise mitigation conditions attached to their building permits when adjacent to residential zones. Contractors doing federal contract work at Emerald Downs or the Muckleshoot Tribe casino must still comply with Auburn construction hours when the work site is inside city limits.
Work outside the allowed window is a public disturbance infraction under ACC 8.28.010. Repeated violations can draw stop-work orders from Auburn Development Services and civil penalties.
