SDCI is in the process of updating Seattle’s construction codes to the 2018 versions of the building, residential, existing buildings, fire, electrical, mechanical, energy, fuel gas, elevator, boiler, and plumbing codes. Due to many factors, including the impacts of the COVID-19, the 2018 Washington State Construction Codes effective date has been delayed. SDCI will be aligning the effective date of our 2018 code versions with the State’s current effective date of February 1, 2021.
The City Council approved an amendment to the 2015 Seattle Building Code allowing Art Gallery spaces less than 3000 square feet in size to remain or be classified as an Mercantile occupancy from an Assembly-3 occupancy. They also approved legislation for Seattle’s Technical Codes and Electrical Code.
SDCI’s Technical Code Development team is excited to announce that the 2015 Seattle codes are now available. The 2015 codes include the Building Code, Existing Building Code, Residential Code, Energy Code, Plumbing Code, Mechanical Code, and Fuel Gas Code. These codes are available on our codes webpage. The codes are available to purchase from the Public Resource Center on the 20th floor of Seattle’s Municipal Tower.
