Construction hours in Federal Way, WA — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Federal Way permits construction under WAC 173-60.050 exemptions between 7 AM and 10 PM. Sunday work near homes is typically restricted. Work outside the window must meet 55/45 dBA limits.
Federal Way adopts WAC 173-60.050 exemptions for temporary construction, maintenance, and repair. Under the state rule incorporated through FWRC Title 7, sounds created by temporary construction, maintenance, or repair projects are exempt from the decibel limits of WAC 173-60.040 between 7 AM and 10 PM. Federal Way code enforcement treats 7 AM to 8 PM on weekdays as the reasonable operational window for heavy construction adjacent to residential zones. Outside that window, construction site noise must meet the 55 dBA residential daytime or 45 dBA nighttime receiving limit, which is effectively impossible for most heavy equipment, trucks, and compressors. Homeowner projects such as lawn mowing, pressure washing, and small home improvements are similarly exempt between 7 AM and 10 PM. Emergency utility repairs and public works emergencies (storms, water main breaks) are exempt at all hours. Major projects along the I-5 corridor or near Pacific Highway South must also meet WSDOT noise mitigation standards during freeway-adjacent work.
After-hours construction noise that exceeds WAC 173-60 limits at a residential receiving property is a civil infraction. Repeat violations can trigger stop-work orders from Federal Way Community Development.
