Janitorial and commercial cleaning leads in the United States

Commercial cleaning in the US is a crowded field of mostly small firms. County Business Patterns counted 67,799 janitorial services establishments in 2023, employing 1,088,193 people between them. The Bureau of Labor Statistics puts total employment of janitors and cleaners at 2,209,760 in May 2025, which includes in-house staff at schools, hospitals and government buildings as well as contractors. The gap between those two figures matters to you: a large share of cleaning is still done by employees on a building's own payroll, and every one of those buildings is a possible conversion to an outside contractor.

Where the work sits follows where people and offices sit. BLS data for May 2023 shows the heaviest concentrations of janitorial employment in the New York, Los Angeles, Chicago, Washington, Dallas-Fort Worth and Houston metros. Services to buildings and dwellings is the largest single employer of janitors, at about 35 percent, followed by education at 17 percent and healthcare and social assistance at 7 percent. Those three groups (contracted commercial space, schools and campuses, and medical buildings) are where most recurring contracts get signed.

For a cleaning company, the practical question is never how big the US market is. It is how many decision-makers inside your drive time want regular work this quarter. A dense metro can support a tight territory of a few ZIP codes. A rural state may need a whole region to produce steady volume. Both work. We look at your area with you on the call and say honestly what the building stock there supports.

What changes through the year

Demand moves with the weather and the calendar, and it moves differently by region. Northern states see heavy floor care in winter as salt and slush get tracked through lobbies. The Gulf and Atlantic coasts plan around hurricane season from June to November. Schools and campuses push deep cleans into summer break and the weeks before term. Across the country, many businesses set budgets in the fourth quarter and switch cleaning vendors in January, which makes late fall a useful time to be in front of them.
