SDCI and Washington state update their adopted construction codes every three years. The current updates creating the 2021 series of codes for SDCI and Washington state where slated to be adopted and implemented by July 1, 2023. However, SDCI’s proposed updates will be delayed.
The 2021 Seattle Construction Codes effective date of July 1, 2023 is delayed to no sooner than Monday, October 2, 2023 to accommodate a City of Seattle legislative review process which is longer than anticipated this code cycle.
