LOCATION: City Wide STAFF: Minnie Dhaliwal, Deputy Director ATTACHMENTS: A. Map of ADU Registrations received during amnesty program B. Ordinance 2581 BACKGROUND Ordinance 2581 adopted by the City Council on July 2, 2018, updated Tukwila's Accessory Dwelling Unit (ADU) regulations. The updated regulations allow for detached ADUs and require new and existing ADUs to apply for registration. A one-year amnesty period adopted under Ordinance 2581 allowed for property owners with ADUs that were created illegally or which were in existence prior to an area's annexation to come forward to register their ADUs under more flexible zoning rules, provided the units met building code's life safety standards. Zoning flexibility given to existing ADUs applying for registration during the amnesty period included the following: • Exceeding the permitted height for a detached ADU • Exceeding the permitted area for an attached or detached ADU, up to 1,200 square feet • Not providing a second parking space for a two bedroom ADU • Roof pitch of less than 5:12 • Location of the ADU on the lot. Owner occupancy, providing at least one parking space per ADU, and meeting the minimum lot size for a detached ADU were conditions that could not be waived per Council direction. The one-year amnesty registration period ended on July 1, 2019. A total of 30 ADU Registration Applications have been received since the city adopted the new ADU regulations. A total 21 were received during the Amnesty program and only four asked for relief from zoning standards under the Program. See attached map for the location of these ADUs. Here is the current review status of these applications: Approved: 9 Denied: 1 Withdrawn:2 Under construction (not pre-existing but new): 8 Pending: 10 (waiting for the applicant to fix items identified during construction or record owner occupancy affidavit) Tukwila City Hall . 6200 Southcenter Boulevard .
