The purpose of the Code Interpretation is to clarify methods to provide separation between townhouse units designed to the 2018 Seattle Residential Code. Typically, the code requires a fire-resistance-rated wall assembly to provide continuous separation between units from foundation to roof. There are several conditions where separation is required to extend beyond this enclosed floor area.

Applicants can submit complete permit applications using either the 2015 or the 2018 versions of the Seattle construction codes between the state’s implementation date of February 1, 2021 and Seattle’s implementation date of March 15, 2021.
