81131

Analysis

NAICS 81131 is the 2022 NAICS industry for commercial and industrial machinery and equipment (except automotive and electronic) repair and maintenance, part of 8113 (Commercial and Industrial Machinery and Equipment (except Automotive and Electronic) Repair and Maintenance).

It has only one more detailed code, 811310, which covers exactly the same activities; the definition, index entries and statistics are on that page.

County Business Patterns counts 22,907 US establishments in this code in 2023, employing 219,835 people at an average annual payroll of $73,266 per employee (58th percentile of national industries). 60% 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 4% and employment rose 8%. 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.
