The Washington State Building Code Council (SBCC) previously voted to approve an extension of the 2018 International Building Code and other accessory code adoption from February 1, 2021 to July 1, 2021. However, on January 19, 2021, Governor Inslee repealed that extension. The effective date is once again February 1, 2021.
Until January 31, 2021, the city will continue to implement the 2015 International Codes as adopted in Mountlake Terrace Municipal Code (MTMC) Chapter 15.05. Beginning February 1, 2021 the city will implement the 2018 International Building Code(s).
