Middle housing is not new. These housing types were common in neighborhoods built before World War II. We still see them in many thriving historic districts and older neighborhoods.
Expanding opportunities for middle housing in newer neighborhoods – where detached houses might currently be the only housing type available – is a recent concept. In 2019, Minneapolis was the first city to adopt a policy to boost middle housing potential in all residential zones city-wide. Several Oregon cities, including Bend and Portland, adopted similar policies.
In 2019, Oregon became the first state to require cities and counties to expand middle housing opportunities.
