This week, the King County Council Committee of the Whole held a public hearing on the 2020 midpoint update to the Comprehensive Plan. This update includes land use code amendments to encourage more ADU and cottage housing development. The Council has provided striking amendments to the initial plan to allow for flexible square footage in cottage housing developments—up to 1,500 square feet, with 250 square feet of unheated garage space. The striking amendments to the ADU proposal would:

  • Allow townhouses to have ADUs;
  • Reduce minimum lot size in urban or rural towns from 5,000 to 3,200 square feet;
  • Add modifications to the maximum square footage allowed, including the allowance for basements to be excluded from the maximum square footage and for 1,000 square feet of unheated area;
  • Removal of off-street parking requirements; and
  • Expand the owner occupancy requirement to include immediate family.

The Council has continued the public hearing to July 7, when they will deliberate and may take final action. For more information, see 2020 King County Comprehensive Plan Update.
