Self-storage occupancy rates are currently declining. While occupancy typically declines seasonally during the second half of the year, the amount of occupancy lost at the end of 2022 outpaced the trend set in 2021.  The decline in occupancy contributes to lower pricing as operators seek to fill vacant units.

The last quarter of 2022 saw more storage tenants move out of storage than move in. This normal seasonal pattern has not occurred since the start of the COVID-19 pandemic. The pandemic created a surge in demand. The following chart shows the industry move-in/move-out (MIMO) ratio for the last two years. In December 2022 the MIMO was 0.95, meaning for every 100 people that vacated a storage unit, only 95 new tenants moved in.

As the pandemic impacts have dissipated, so have many of the tenants that rented during that time. Meanwhile, the housing market remains stagnant with existing home sales declining for 11 straight months. In addition, rising rental rates are keeping many apartment dwellers in place. Together these two trends contribute to lower numbers of new storage renters than the industry has recently seen this time of year.

  1. When you mention the statistics of sizes that people rent ie. 10×10 16%, 10×15 15.3%, is that the total sizes in a facility or square footage in a facility?

    Thanks Dominic

  2. Great Info! I’d love to see more of the info in a graph spanning the past 15 years or so like the construction spending does. That is very powerful to look at as a trend! As always, valuable and interesting content Mr. Harris.

  3. Alexander – do you happen to have a link to demographics about who is actually investing/buying storage properties. I am doing research and haven’t been able to find any key indicators on buyers.

    1. I would assume you have contacted the major self storage brokers? They would be a good source for you. Feel free to contact Mark Floria, in our company, as he has brokered $100s millions of self storage and can give you a good feel as to who is investing in Michigan and the Midwest. 248-420-4612; [email protected]

  4. i would like to start a business helping people create functional, usable space in their units to empower them with efficiency by de-cluttering, organizing and cleaning.
    Any thoughts?

    1. Omg please call or text me Chris. I am a software developer. I am about to drop the H-Bomb on the self storage budiness. Come with me. 9713023737
      …i have access to the creator of Uber. Call or text me sir. I think i am EXACTLY what you are looking for.

  5. I’m looking for a contact list of self-storage facility owners/managers. Does anybody know where I can find one? We’re an LED lighting manufacturer targeting self-storage warehouses to convert their old fluorescent lighting to more energy efficient LED lighting.

  6. Some of the information seems overblown and without context. Whenever I see stats showing over 50,000 self storage facilities it makes me question what is the definition of self storage? The guy that has 30 units in a metal building in the middle of a corn field, does that equate to self storage?
    Also, the stat showing over 8 sq.ft./person seems suspect as well. The past few years the common wisdom has been that there is about 7 sq.ft./person and I wonder where that stat came from.

    1. Hello. Yes 50,000 is definitely on the higher end of estimates using the broadest definition of storage. We are continuing to update this page on an ongoing basis with new information. Thanks for your input!

  7. Looks like the construction trend is about to create an oversupply. Boom and bust and then someone always gets hurt in the bust.
