Construction hours in Bellevue, WA — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Bellevue permits construction 7 AM-8 PM weekdays and 8 AM-6 PM Saturdays under BCC 9.18.020. No construction on Sundays or legal holidays. After-hours noise is a disturbance.
Under BCC 9.18.020, construction site noise is exempt from the 55 dBA residential daytime limit only during permitted hours: 7 AM to 8 PM Monday through Friday, and 8 AM to 6 PM on Saturdays. No construction noise is permitted on Sundays or legal holidays. Outside these windows, any sound from a construction site that is clearly audible across a property boundary or at least 75 feet from the source is treated as a noise disturbance under BCC 9.18.040. Single-family home maintenance (mowing, pressure washing, light repair) is exempt between 7 AM and 8 PM weekdays and 9 AM and 8 PM weekends. Large projects with extended hours must obtain a construction noise authorization from the Development Services Department and follow public notice requirements. Ordinance 6786 expanded these authorizations for major downtown, light-rail, and transit projects.
After-hours construction: noise disturbance citation. Repeat violations can result in stop-work orders issued by Development Services.
