Portland’s neighborhoods have always been places of change. By 2035, Portland will grow by more than 100,000 households. The city’s popularity, changes in housing demand and other factors have resulted in a housing shortage that has driven up housing costs. Also, housing market changes have made it more attractive to construct large, expensive new houses in older residential neighborhoods — even as the number of people per household is getting smaller. To address these issues around growth and change, the City of Portland made significant revisions to the rules that govern the types of housing permitted in our neighborhoods. The Residential Infill Project, passed in 2020, allow more housing options in Portland’s neighborhoods, including duplexes, triplexes and fourplexes. Explore these changes with Morgan Tracy with the Portland Bureau of Planning and Sustainability.
