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 Idaho charges in sales tax, whether it licenses cleaning companies at all, and what its wage floor does to Nampa 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.
Idaho does not charge sales tax on commercial cleaning services, so a Nampa cleaning quote is the whole price - Idaho state sales tax is 6%. Only enumerated services are taxable: meals and drinks, admissions, recreational use of property or facilities, and production/fabrication/printing labor. Cleaning and janitorial are not enumerated..
Most states do not license commercial cleaning companies, which surprises buyers who assume a board exists to check - in Nampa that means insurance certificates, a written scope and real references do the verifying that a licence would elsewhere.
Idaho janitors and cleaners earn a median of $17.36 an hour per federal wage data, which is the labor floor under every Nampa cleaning quote - labor is roughly the whole cost structure in this trade.
The federal rules for cleaning contractors are thin; the expensive differences are state-level. Whether Idaho charges sales tax on cleaning services, whether it licenses cleaning contractors at all, and what its wage floor does to labor cost are the three that show up in a Nampa quote. All three are below with official sources.

What Idaho adds to a cleaning contract
| Question | Idaho answer |
|---|---|
| Sales tax on commercial cleaning | No - not taxable - Idaho state sales tax is 6%. Only enumerated services are taxable: meals and drinks, admissions, recreational use of property or facilities, and production/fabrication/printing labor. Cleaning and janitorial are not enumerated. Some resort cities levy local option taxes. (Idaho Code 63-3612) |
| Median janitor wage (federal data) | $17.36 per hour |
| State minimum wage | $7.25 |
Idaho taxes only a short enumerated list of services - meals, admissions, recreation and fabrication labor - so commercial cleaning contracts carry no sales tax.

Why Idaho rules move Nampa 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 Nampa buyer can verify before signing.
What this means in Nampa
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 Nampa building that misses the 30-day window has bought another full year at whatever the new rate is.

Common questions
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.
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.
Is a certificate of insurance enough proof?
It is a starting point, not proof. The standard certificate states in its own header that it confers no rights upon the certificate holder - it is a snapshot of what was in force the day it was issued, with limits that may already be partly consumed by other claims. Ask the broker to send it directly, have your entity named as additional insured, and re-request it at renewal.
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.
