What Is It?

What It Isn’t

Our noise program does not cover:

Rules to Follow

Our ordinance requires that you:

  • Limit construction noise, in general, to the following times:
    • 7:00 a.m. - 10:00 p.m., weekdays
    • 9:00 a.m. - 10:00 p.m., weekends and holidays
  • Have commercial projects screened during plan or permit review for potential noise issues. Mitigation measures for major noise generators are required for such projects. 
  • Obtain a noise variance if needed for your project. A noise variance allows noise to occur during a construction project at a time or place where it normally would be prohibited.

If testing or maintenance at Boeing Field takes place outside the approved hours, you may file a complaint with us by emailing a noise abatement specialist.
