What the state adds to the price, and what it lets you verify
Federal rules for cleaning contractors are thin; the expensive differences are state-level. What Maryland charges in sales tax, whether it licenses cleaning companies at all, and what its wage floor does to New Carrollton labor cost are below with official sources.
Two free marketplace paths: one request brings back multiple vetted cleaning contractors who know they are competing for the account.
Maryland taxes cleaning services only in part, and the split usually falls exactly where New Carrollton business buyers sit. 6% state rate, no local add-on.
Most states do not license commercial cleaning companies, which surprises buyers who assume a board exists to check - in New Carrollton that means insurance certificates, a written scope and real references do the verifying that a licence would elsewhere.
Maryland janitors and cleaners earn a median of $17.61 an hour per federal wage data, which is the labor floor under every New Carrollton cleaning quote - labor is roughly the whole cost structure in this trade.
Cleaning is labor, and labor is priced locally. What Maryland sets as its wage floor, and what janitors in the state actually earn at the median, explain more of the spread between New Carrollton quotes than any vendor's sales pitch does.
The federal rules for cleaning contractors are thin; the expensive differences are state-level.

What Maryland adds to a cleaning contract
| Question | Maryland answer |
|---|---|
| Sales tax on commercial cleaning | Partly - depends on the work - 6% state rate, no local add-on. Applies to cleaning of a COMMERCIAL or INDUSTRIAL building, including floor, carpet, wall, window, ceiling and exterior cleaning and janitorial services. Residential cleaning is outside the definition and untaxed. (Md. Tax-General Sec. 11-101(m)(3)) |
| Median janitor wage (federal data) | $17.61 per hour |
| State minimum wage | $15.00 |
Maryland is one of the few states that taxes commercial janitorial work but not residential: cleaning a commercial or industrial building carries 6% sales tax, so a quote for an office is taxed while the identical house cleaning is not.

Why Maryland rules move New Carrollton quotes
Two of the three state variables land directly on your invoice. Sales tax, where a state charges it on cleaning services, is added to every monthly bill - on a mid-size contract that is real money over a year. The wage floor sets the labor cost every bid is built on, which is why identical buildings in different states get materially different quotes. Licensing is the third and it works differently: it does not change the price, it changes what a New Carrollton buyer can verify before signing.
What this means in New Carrollton
The most expensive cleaning contract is the one that renews itself. The common evergreen clause continues the agreement for successive twelve-month periods with no 'unless you give notice' language attached - so a New Carrollton building that misses the 30-day window has bought another full year at whatever the new rate is.

Common questions
Do I have to pay sales tax on cleaning services?
That depends entirely on your state - most states do not tax cleaning services, but a minority do, and in those states it is a real line on a real invoice: at typical rates it adds several percent to every monthly bill. This site publishes the treatment state by state with the revenue department's own source; check your state's page.
Are commercial cleaning companies licensed?
In most states there is no cleaning-specific license to check, which surprises buyers who expect a board to verify. A few states do license or register cleaning contractors, and many cities require a general business license. Where there is no license, verification falls to insurance certificates, references and written scope - not to a registry.
How much does office cleaning cost per month?
For a small office cleaned three times a week, published ranges start around $100-$250 a month at the smallest sizes and run to $250-$800 for a few thousand square feet, with larger spaces at $350-$1200 and up. Restroom count, floor type and whether consumables are included move these more than most buyers expect.
Am I liable for the cleaning company's employees?
Usually not, but the boundary matters. Joint-employer liability, where it exists, is joint and several - meaning each employer can be responsible for the full amount of wages owed. Federal labor regulators have proposed guidance indicating that giving routine instructions, monitoring quality, or even asking for a worker to be replaced does not by itself create that status; directly scheduling workers, keeping their time records and controlling hiring and firing points the other way. This is a fact-specific area - ask counsel about your own arrangement.
How much does commercial cleaning cost per square foot?
In 2026 industry ranges, general office space runs about $0.09-$0.17 per square foot per month, medical and healthcare $0.14-$0.29, industrial $0.08-$0.20, retail $0.07-$0.15 and schools $0.07-$0.14. Those figures assume a stated frequency - a per-square-foot price without a frequency attached tells you nothing.
