Seattle’s Noise Ordinance contains rules to minimize Seattle resident's exposure to excessive noise. Under the ordinance, we screen commercial projects during plan or permit review for potential permanent mechanical and recurrent noise issues associated with using and maintaining your facility. We require mitigation measures for major noise generators for such projects.
Some construction projects may also have land use permit or State Environmental Protection Act (SEPA) noise restrictions. If you have a concern about construction noise, noise from mechanical equipment, or a commercial facility in the Seattle city limits, you may file a complaint with us or discuss it with one of our noise control specialists.
