Construction Noise Guidelines
Under the Bellevue City Code, noise emanating from construction sites that exceeds allowed noise levels is prohibited outside of the hours of 7 a.m. to 6 p.m., Monday through Friday, and 9 a.m. to 6 p.m. on Saturdays. No construction site noise is permitted on Sundays and legal holidays.
If after-hours sounds from a construction site are clearly audible across a real property boundary or at least 75 feet from their source, it will be considered a noise disturbance (BCC 9.18.040.A.4).
The Construction Noise Guidelines handout offers more details.
