Built Green is an environmentally-friendly, non-profit, residential building program of the Master Builders Association of King and Snohomish Counties, developed in partnership with King County, Snohomish County, and other agencies in Washington State. This website provides consumers with easy-to-understand rating systems, which quantify environmentally friendly building practices for remodeling and new home construction, communities and multifamily development units. We hope you will consider buying or remodeling according to Built Green standards, becoming a member of Built Green, or sponsoring our program.

 

 

Our builders and other associates provide sustainable housing in an area of more than 4,000 square miles in the State of Washington, covering King and Snohomish Counties. Built Green homes are designed to provide homeowners with comfortable, durable, environmentally friendly homes that are cost-effective to own and operate. These resource-efficient homes are crafted to exceed building codes and provide homeowners with years of healthy, quality living, while protecting the precious Northwest environment.
