When we look at the top operators of 2019, there are several items worth noting. For starters, the top-five list has reverted to the same self-storage real estate investment trusts (REITs) as the 2017 list: Public Storage remains No. 1, Extra Space Storage stays in second, CubeSmart is third, U-Haul ranks fourth, and Life Storage is back in fifth. In 2018, Life Storage ranked sixth when National Storage Affiliates (NSA) overtook its place as the fifth largest self-storage operator in the United States. However, over the past year, Life Storage added more than 8 million net rentable square feet of storage space to its portfolio to reclaim its position as No. 5.
