The missing middle construction sector includes development of medium-density housing, such as townhouses, duplexes and other small multifamily properties.
The multifamily segment of the missing middle (apartments in 2- to 4-unit properties) has generally disappointed since the Great Recession. However, there was a noticeable uptick for this type of housing construction in the most recent data, according to analysis from the National Association of Home Builders. For the third quarter of 2024, there were 6,000 2- to 4-unit housing unit construction starts. This is double the pace of construction from a year prior.
As a share of all multifamily production, 2- to 4-unit development was just above 6% of total multifamily development for the third quarter. However this is still lower than recent historic trends. From 2000 to 2010, such home construction made up a little less than 11% of total multifamily construction. Construction of the missing middle has clearly lagged during the post-Great Recession period and will continue to do so without zoning reform focused on light-touch density. But recent data offer hope for additional housing supply for these kind of structures.
