Analysis
NAICS 53113 is the 2022 NAICS industry for lessors of miniwarehouses and self-storage units, part of 5311 (Lessors of Real Estate).
It has only one more detailed code, 531130, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 18,564 US establishments in this code in 2023, employing 48,382 people at an average annual payroll of $40,550 per employee (9th percentile of national industries). 91% of the establishments have fewer than five employees, which marks it as a small-business industry.
Between 2018 and 2023 the number of establishments grew 10% and employment rose 9%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
By establishments it ranks 3rd of the 4 codes at this level within Lessors of Real Estate, with 13.6% of them.
