Illinois had 2,520 janitorial services in 2023, ranking number 5 among the 50 states and the District of Columbia. Together they employed 50,936 people and paid $1.6 billion in annual payroll, an average of 20.2 employees per site.
These businesses make up 0.78% of every employer establishment in Illinois, close to the 0.81% national share. A site count is not the same as the number of companies: a chain with 40 locations counts 40 times.
64% of janitorial services in Illinois have fewer than 5 employees, against 61% across the U.S.

Questions
How many janitorial services are in Illinois?
The Census Bureau's County Business Patterns counted 2,520 janitorial services with paid employees in Illinois in 2023. That ranks Illinois number 5 among the 50 states and the District of Columbia.
Is the number of janitorial services in Illinois growing?
Between 2017 and 2023 the count shrank (1.4%), from 2,557 to 2,520. Across the United States the count changed by +12.5% over the same period. These years include the 2020 pandemic.
Does this count include self-employed owners with no staff?
No. County Business Patterns covers establishments with at least one paid employee. A sole proprietor with no employees is counted in a separate Census series called Nonemployer Statistics, which this site does not use yet, so the real number of people working in this trade is higher than the figure shown.
