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.
