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 South Dakota charges in sales tax, whether it licenses cleaning companies at all, and what its wage floor does to Interior 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.
South Dakota charges sales tax on commercial cleaning services, so every Interior cleaning invoice carries tax on top of the contract price - South Dakota taxes 'the sale of all services' unless specifically exempted, so commercial cleaning is fully taxable. State rate 4.2%, plus municipal sales tax (commonly 1-2%). No residential vs commercial distinction was found..
South Dakota does not license commercial cleaning companies, so there is no state registry for Interior buyers to check - verification falls to insurance certificates, written scope and references, which is exactly why those three matter here.
South Dakota janitors and cleaners earn a median of $17.06 an hour per federal wage data, which is the labor floor under every Interior cleaning quote - labor is roughly the whole cost structure in this trade.
Cleaning is labor, and labor is priced locally. What South Dakota sets as its wage floor, and what janitors in the state actually earn at the median, explain more of the spread between Interior quotes than any vendor's sales pitch does.
The federal rules for cleaning contractors are thin; the expensive differences are state-level. Whether South Dakota 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 Interior quote. All three are below with official sources.

What South Dakota adds to a cleaning contract
| Question | South Dakota answer |
|---|---|
| Sales tax on commercial cleaning | Yes - taxable - South Dakota taxes 'the sale of all services' unless specifically exempted, so commercial cleaning is fully taxable. State rate 4.2%, plus municipal sales tax (commonly 1-2%). No residential vs commercial distinction was found. |
| Licence or registration required | No state licence for cleaning companies - No cleaning-specific occupational license; because South Dakota taxes services, a commercial cleaner must hold a state sales tax license from the Department of Revenue and register its entity with the Secretary of State. |
| Median janitor wage (federal data) | $17.06 per hour |
| State minimum wage | $11.85 |
South Dakota flips the usual rule - it taxes the sale of all services unless a statute exempts them - so commercial cleaning carries the 4.2% state tax plus municipal tax on top, raising the effective quote by roughly 6%.

Why South Dakota rules move Interior 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 Interior buyer can verify before signing.
What this means in Interior
'Bonded' sounds like protection and functions like credit: the bond pays only after an employee is criminally convicted, and the cleaning company repays the surety afterward. If theft protection is what a Interior buyer actually wants, the thing to verify is the contractor's own crime coverage and hiring screening, not the word 'bonded' on a flyer.

Common questions
Do I still need pandemic-level disinfection?
Federal guidance now tells buyers to determine whether disinfecting is necessary at all before purchasing disinfectants, and notes that disinfectants - which EPA regulates as pesticides - are more hazardous than plain cleaners. Routine whole-building fogging sold as standard is worth questioning; targeted disinfection of high-touch surfaces where circumstances warrant it is a different conversation.
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.
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.
How do I compare two very different cleaning bids?
Normalize three things before you look at price: total cleanable square footage, frequency per area, and exactly which specialty services are inside the monthly fee. Most large gaps between bids disappear once those are matched - and the ones that survive are usually explained by staffing model or supervision, which is worth paying for.
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.
