The city of Portland changed its zoning rules in 2020 with the goal of producing duplexes, cottage clusters and other multi-unit housing in areas traditionally zoned for single-family homes. The idea was to provide more options at more affordable price points for the city’s growing population. A new report shows the initiative is largely working. It says more middle housing units are now being built than single-family homes, and those units are selling for $250,000 to $300,000 less than a new, market-rate detached house.

Morgan Tracy is a senior planner in Portland’s Bureau of Planning and Sustainability. He joins us with more of the report’s key findings.
