Analysis
NAICS 53139 is the 2022 NAICS industry for other activities related to real estate, part of 5313 (Activities Related to Real Estate).
It has only one more detailed code, 531390, which covers exactly the same activities; the definition, index entries and statistics are on that page.
Between 2018 and 2023 the number of establishments grew 33% and employment rose 27%. 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.
County Business Patterns counts 23,159 US establishments in this code in 2023, employing 78,923 people at an average annual payroll of $101,505 per employee (85th percentile of national industries). 87% of the establishments have fewer than five employees, which marks it as a small-business industry.
By establishments it ranks 2nd of the 3 codes at this level within Activities Related to Real Estate, with 20.2% of them.
