Built Green is a voluntary program that requires third-party verification. The program requires builders or developers to follow a specific set of criteria to attain status as a "Built Green" home or community. Beyond these standards, builders will earn a rating based on a point system.
After reviewing the completed checklist provided by the builder, the Master Builders Association of King and Snohomish Counties will issue a 3-, 4-, 5- or Emerald Star rating for the project. All certifications require verification by a third party.
