What to Know About Investing in Self Storage

Reading Time: 4 minutes

Although the percentage of self storage investments may be low compared to the entire commercial real estate sector, the self storage industry is rapidly maturing into a core asset class on par with office, retail, multifamily, and industrial.

There is currently more than 1.5 billion square feet of self storage space in the U.S., and 1 out of every 3 Americans use self storage space, according to the Self Storage Association’s most recent Self Storage Demand Study.

While self storage properties may fly under the radar screen of many, there are more self storage facilities in the U.S. than all of the Subway, KFC, Pizza Hut, and Taco Bell locations combined.

Characteristics of the self storage asset class

Self storage properties are often viewed as the ideal asset class for conservative investors seeking more predictable returns than value-add or opportunistic investments. 

Both general consumers and businesses rent self storage space

As with most commercial real estate projects, the new construction of self storage facilities slowed during the pandemic. However, the new supply of self storage space in the pipeline remains steady, driven by robust investor demand and economic recovery. 

Developers delivered 64 million square feet of self storage space last year, and another 49 million square feet will come onto the market in 2021. The national average monthly rent for self storage space is $1.37 per square foot, with the average self storage unit renting for $145 per month.

While self storage has long been used for consumer storage, businesses are also driving demand. 

According to a recent Reporterlinker study, clothing manufacturers producing seasonal items are opting for temporary self storage space as a more cost-effective alternative to traditional year-round warehouse space

E-commerce players are increasingly using self storage space to store products for last-mile delivery, helping to mitigate inventory management problems and strengthen supply chain operations.

Things to Know Before Investing in Self Storage

Millennials are by far the largest cohort of users of self storage space, with 36% keeping items in storage. More than two-thirds of millennials rent self storage units because of relocation, not having enough space at home, or a change in household size.

Overall, when looking at self storage rental patterns, 33% of users rent for between 2-6 months, while 39% rent for over one year. Over 50% of self storage users rent unit sizes of 10’ x 10’ or larger, while nearly twice as many women as men rent self storage space.

Here are some of the pros and cons to investing in the self storage asset class:


  • Minimal construction costs with self storage units easy to build and maintain.
  • Economically resilient with self storage seeing demand through all economic cycles.
  • A flexible business model with short-term leases allows owners to adjust rental rates to market demand.
  • Value-add revenue streams from products such as packing supplies, moving equipment, and tenant-insurance.


  • Self storage unit mix and amenities – such as interior vs. drive-up space, climate-controlled, and 24/7 access – must be carefully analyzed to meet the local market’s needs.
  • Hiring and retaining on-site management for larger self storage facilities can be challenging.
  • Changing tenant demographics may affect the future demand for self storage space.
  • Month-to-month leases can mean a larger percentage of tenant turnover.
