Increased housing must go hand in hand with enhanced livability. The quality of housing options, as well as investment in community amenities, services and transit, are all critical if Seattle is to remain a great and welcoming place to live.

Our Priorities for Housing

  • Increase the supply of housing for all income levels
  • Increase flexibility to design a range of housing types and styles
