The 2012 Seattle Energy Code went into effect December 27, 2013. The date of your project’s associated building permit application will determine which version of the energy code applies to your project. If your building permit application is dated before December 27, 2013, we will review your electrical plans under the 2009 Seattle Energy Code. All other electrical plan review submissions must comply with the 2012 Energy Code.
Over-the-counter and online applications submitted on or after April 14 will be inspected for compliance with the 2012 Energy Code.
Incorporating the 2012 code changes into your designs will provide shorter turn-around and project completion time. Codes are available on DPD’s Codes We Enforce web page.
