Living habits lead to changes in apartment size

Changes in renters’ living habits are literally redrawing floor plans, according to the RentCafe study.

The largest share of apartment dwellers, millennials prefer living in locations close to restaurants and entertainment rather than having a large kitchen or living room to cook or entertain at home.

Studio apartments — the symbol of downtown living — have been cut down the most. The average studio apartment is 10% smaller than 10 years ago, reduced from 573 sqft in 2008 to 514 sqft this year.

Contrary to the growing interest in smaller units, studio apartments continue to represent a small piece of the rental market, only 5% nationally of all apartments. One-bedroom rental units make up the largest chunk of the national apartment stock (43%) and their floor plans have decreased by 4% over the last decade, while two-bedroom apartments have seen the least change in size, down by only 0.5% on average.

RentCafe ranked the top 100 cities with the largest rental stock in the country by the average size of their rental apartments.
