If the living room in your apartment can’t fit a couch and a dining table, you’re not alone. Over the past decade, the average size of newly constructed rental apartments has shrunk by 22 square feet. The average size of a new rental unit is now a mere 908 square feet, according to a report from RentCafe.
Researchers analyzed data on the size of new apartments in the 100 U.S. cities with the largest stock of rental buildings with at least 50 units. Newly built apartments were defined as those completed from 2015 through February 2025. Data was harvested from RentCafe’s parent company, Yardi, which surveys rental properties.
A proliferation of studios and one-bedrooms is partly responsible for the downsizing. These units grew from 46 percent of what was built before 2015, to 53 percent in the years since.
Driving the need for smaller apartments are an increasing number of young, professional singles and a related drop in marriage rates. With interest rates remaining stubbornly high, more of these singles are opting to rent rather than buy. Developers also have an incentive to build smaller units, which can boosts profits by leaving space for additional ones.
Despite the decade-long downward trend in new apartment size, there’s been an uptick recently, with rentals gaining 17 square feet in the past two years. Even cities experiencing some of the worst housing shortages have seen notable gains.
