Green Building and Sustainable Development Ordinance

The King County Green Building and Sustainable Development Ordinance (PDF, 825 K) went into effect in July, 2008. The Green Building Initiative started in 2001 with an Executive Order which was replaced by an ordinance in 2005.

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 and Sustainable Development Ordinance Requirements

  • The ordinance covers all King County-owned and county-financed projects, including projects using alternative financing.
  • All eligible new construction and major remodel and renovation projects are required to achieve the LEED Gold certification.
  • All capital projects that are not eligible or are limited in their ability to achieve LEED certification (e.g., infrastructure projects) must incorporate cost-effective green building and sustainable development practices using a county-developed "scorecard" or checklist.
  • The County-wide Green Building Team is directed to develop guidelines (PDF, 1.7 MB) for using green practices in operating and remodeling existing buildings.
  • The ordinance also specifies reporting requirements to improve the information compiled on county divisions' green practices; continues the county-wide Green Building Team and clarifies its roles and responsibilities; and requires project managers to be trained in green building practices.
