Seattle Mayor Jenny Durkan has issued an executive order directing city departments to help homeowner efforts to add Accessory Dwelling Units (ADUs) to their properties by lowering red tape and expenses. The order directs the following:

  • Seattle Department of Construction and Inspections (SDCI) will streamline the design and permitting process for detached accessory dwelling units (DADUs) by providing pre-approved designs which can be permitted in 30 days.
  • SDCI will hire an “ADU Navigator” on the permitting staff to help homeowners navigate the permitting process for ADUs.
  • SDCI will work with the Office of Planning and Community Development (OPCD) and Seattle Information Technology (Seattle IT) and other departments to develop a one-stop ADU website. They will also establish and convene an ADU working group, including experienced ADU designers, builders, owners, landscape architects or arborists, environmental advocates, and residents to provide educational opportunities, tours, and events.
  • Office of Housing (OH) will use the existing Home Repair Program to develop a pilot program for low-interest financing to help low-income homeowners create ADUs.
  • The city will work with state leaders to create tools and incentives to expand availability of affordable housing options come to market more quickly.
  • SDCI, along with other city departments, will partner with nonprofits, public agencies, and private organizations on models of affordable ADU construction, using best practices.
  • Monitor ADU development trends to measure the development benefits and impacts of ADU production.
