The City of Seattle Ordinance 127205 allows an additional 24-month extension for existing building permit applications and issued permits that are vested to the 2015 or 2018 Seattle Building Code requirements. This legislation aims to prevent significant redesign costs and project cancellations for developers, which would arise if projects were forced to comply with more recent 2021 building code provisions upon permit expiration. To be eligible, property owners must confirm that the project has been delayed due to financing issues and must have requested the extension prior to November 1, 2026. The ordinance applies to over 3,000 distinct project addresses, encompassing an estimated 34,000 housing units. It also details conditions for permit renewals, including applications within 30 days of expiration, valid land use approval, and compliance with current codes or evidence of substantial work progress.
