Analysis
NAICS 23815 is the 2022 NAICS industry for glass and glazing contractors, part of 2381 (Foundation, Structure, and Building Exterior Contractors).
It has only one more detailed code, 238150, 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 15% and employment rose 7%. 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 6,945 US establishments in this code in 2023, employing 68,694 people at an average annual payroll of $69,666 per employee (52nd percentile of national industries). 52% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 6th of the 8 codes at this level within Foundation, Structure, and Building Exterior Contractors, with 6.5% of them.
