This bill establishes a self-certification program for accessory dwelling unit (ADU) project permit applications in cities that plan under chapter 36.70A RCW. It allows registered architects to self-certify compliance with building code requirements for the construction of detached ADUs. The bill mandates that cities adopt rules for the self-certification program, including professional requirements for architects, random audits of self-certified applications, penalties for failed audits, and insurance coverage requirements. Additionally, cities must create a self-certification form that includes various attestations and agreements from the architect and property owner.
Furthermore, the bill requires cities to notify the department of any penalties imposed on architects due to failed audits and establishes a database to track architects subject to penalties. Cities operating the self-certification program must submit a report to the department by July 31, 2028, detailing the number of self-certified projects, permit issuance, and audit results. The department will then compile this information into a report for the legislature by December 31, 2028. The bill also clarifies that it does not affect the validity of any existing self-certification programs prior to its effective date.
