Analysis
NAICS 23829 is the 2022 NAICS industry for other building equipment contractors, part of 2382 (Building Equipment Contractors).
It has only one more detailed code, 238290, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 8,107 US establishments in this code in 2023, employing 150,522 people at an average annual payroll of $90,627 per employee (78th percentile of national industries). 46% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 3rd of the 3 codes at this level within Building Equipment Contractors, with 4% of them.
Between 2018 and 2023 the number of establishments grew 8% and employment rose 11%. 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.
