Residential Infill Project

  • Scale of Houses Should Portland reduce allowances for the size of houses in single-dwelling zones to address community concerns about houses being too large? If so, to what extent?

  • Housing Types What is the feasibility and appropriateness of more duplexes, triplexes and accessory dwelling units (ADUs) to provide more housing options in single-dwelling zones?

  • Historically Narrow Lots What are appropriate lot dimensions for new development on historically narrow lots? Where should these lots be allowed and how can they be better designed?

Portland is growing and our housing needs are changing. Nearly 123,000 new households are projected by 2035. About 20 percent of new housing units will be built in Portland’s single-dwelling residential zones. Increased cultural and racial diversity and an aging population will also affect housing needs. The average number of people per household is getting smaller and households with children are expected to decline to 25 percent over the next 20 years. Portlanders have expressed concerns about the size of new houses, demolitions and the rising cost and lack of housing choices throughout the city. In response, the Bureau of Planning and Sustainability is taking a fresh look at the allowances for development in single-dwelling neighborhoods. See the project summary and timeline for more information.
