Census does not publish a separate category for commercial cleaning and janitorial companies; figures use NAICS 561720, Janitorial Services, the closest official industry. 76.8% of establishments have fewer than 10 employees, so most firms in the industry run outbound with a founder or a very small sales team. The 15,110 firms with 10 to 249 employees are the ones most likely to be building a repeatable outbound process.

The five largest states hold 35.1% of all establishments. Among states with at least 100 establishments, the fastest growth between 2022 and 2023 was in Wyoming (+11.3%), Mississippi (+6.7%) and Maine (+6.5%). Growing markets bring new competitors and new buyers at the same time, which rewards outreach that is specific rather than volume-driven.

How many commercial cleaning companies are there in the US?

There were 67,799 establishments in NAICS 561720 (Janitorial Services) in 2023, employing 1,088,193 people. Source: U.S. Census Bureau, County Business Patterns 2023.

Who hires commercial cleaning services?

Office and facilities managers at tenants, property managers for multi-tenant buildings, and practice administrators or owners at smaller businesses.

What is a good time to contact businesses about cleaning?

When they move into new space, when occupancy increases after return-to-office changes, or when a building changes ownership. Those events reset vendor decisions.

Is cold email legal in the United States?

Yes. The federal CAN-SPAM Act permits commercial email to business contacts without prior consent, provided the message identifies the sender accurately, uses a truthful subject line, includes a valid physical postal address and a working opt-out, and honours opt-out requests promptly. CAN-SPAM applies in every state and preempts most state commercial email laws, except provisions aimed at falsity or deception. This is general information, not legal advice.
