Noise guidelines for unincorporated King County
On July 2, 2015, new, improved noise guidelines for residents living in the unincorporated communities of King County went into effect. Read the full language of the King County Ordinance, Title 12 Public Peace Safety and Morals. If you have a complaint about noise in unincorporated King County, or if you need a permit related to a noisy activity, please see the contact information below.
I. Complaints and violations: (Ordinance Sections 4, 72, 87, 95, 96, 98):
- King County Dept. of Permitting and Environmental Review (DPER) and the King County Sheriff are authorized to respond to and enforce against violations of the new noise ordinance. Violations can consist of disturbance noises, public nuisance noises, construction-related noise outside of permitted hours of work, and sounds exceeding maximum permissible sound levels (decibels) specified in the ordinance. The Sheriff’s role is typically focused on neighborhood noise disturbances (including noise from watercraft), while DPER’s role is focused on oversight of permitted activities that create noise, such as construction work.
- If you’re experiencing loud and raucous neighborhood noise, you should call the King County Sheriff’s non-emergency line at 206-296-3311.
- If it is a construction matter, you should call DPER at 206-296-6680.
