Energy Code - Documents
The effective date for the 2021 Seattle codes is no sooner than September 30, 2024. Until then, applicants may use either the 2018 or draft 2021 Seattle codes. The Mayor’s office is evaluating further code amendments at this time. Once the Construction Codes Advisory Board approves the full suite of 2021 codes, the ordinance will still need to go through the standard ordinance review and approval process for adoption. We do not have a timeline yet for final CCAB approval. Please visit the 2021 Seattle Code Adoption webpage for updates.
