Green Building Ordinance

The King County Green Building Ordinance was adopted in February, 2005 by the King County Council. It replaced the previous 2001 Executive Order which originally implemented the Green Building Initiative.

Green Building Goals

  • Encourage green building practices in all King County building projects, including new construction, renovation and remodeling.
  • Direct county offices and departments to incorporate the use of the Leadership in Energy and Environmental Design (LEED™) green building rating system.
  • Establish a Green Building Team to provide education and guidance to county departments.

Green Building Ordinance Requirements

  • For all new construction, departments are required to apply LEED™ criteria in the pre-design and design project phases and are encouraged to seek the highest LEED™ certification possible (Certified, Silver, Gold, or Platinum).
  • Projects must report to the Green Building Team on a regular basis, and registered projects must provide an update on the status of the LEED™ checklist accomplishments.
  • Remodels and renovations should use the LEED™ reference manual as a guide to incorporate green building practices whenever possible.
