What the number means
California had 6,956 janitorial services in 2023, ranking number 1 among the 50 states and the District of Columbia. Together they employed 116,330 people and paid $4.2 billion in annual payroll, an average of 16.7 employees per site.
These businesses make up 0.68% of every employer establishment in California, below 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.
61% of janitorial services in California have fewer than 5 employees, against 61% across the U.S.
California holds 10.3% of the nation's janitorial services and 12.3% of all U.S. employer establishments, so, measured against the state's overall size, the trade is under-represented. The most common size class is under 5 employees (4,227 sites). Average payroll per employee is $36,126, against $30,089 for the U.S. trade.

Questions
How many janitorial services are in California?
The Census Bureau's County Business Patterns counted 6,956 janitorial services with paid employees in California in 2023. That ranks California number 1 among the 50 states and the District of Columbia.
Is the number of janitorial services in California growing?
Between 2017 and 2023 the count grew (27.1%), from 5,474 to 6,956. 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.
