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 California charges in sales tax, whether it licenses cleaning companies at all, and what its wage floor does to San Francisco 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.
California does not charge sales tax on commercial cleaning services, so a San Francisco cleaning quote is the whole price - California sales tax applies to tangible personal property, not to service-only janitorial labor, because the true object of the contract is the service. Same for residential and commercial..
California requires cleaning contractors to hold a state licence or registration - Every janitorial employer with at least one covered janitorial worker must register with the Labor Commissioner and renew annually; must show valid workers' compensation coverage and provide biennial. - which gives San Francisco buyers something most states do not: a public record to check before signing.
California janitors and cleaners earn a median of $19.75 an hour per federal wage data, which is the labor floor under every San Francisco 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 California 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 San Francisco quote. All three are below with official sources.
Most states do not license commercial cleaning companies, which surprises buyers who assume there is a board to check. What California does or does not require - and what that means for verifying a San Francisco contractor - is set out below, with the state's own source next to it.

What California adds to a cleaning contract
| Question | California answer |
|---|---|
| Sales tax on commercial cleaning | No - not taxable - California sales tax applies to tangible personal property, not to service-only janitorial labor, because the true object of the contract is the service. Same for residential and commercial. Rug and carpet cleaning charges are also untaxed; the cleaner pays tax as consumer of its supplies. (Cal. Code Regs. tit. 18, sec. 1501 (Service Enterprises Generally); CDTFA Annotation 360.0180 (Rug and Carpet Cleaners)) |
| Licence or registration required | Yes - Every janitorial employer with at least one covered janitorial worker must register with the Labor Commissioner and renew annually; must show valid workers' compensation coverage and provide biennial sexual harassment prevention training. Contracting with an unregistered provider is itself penalized. (California Labor Commissioner's Office, Division of Labor Standards Enforcement (Department of Industrial Relations)) |
| Public licence lookup | https://cadir.my.salesforce-sites.com/RegistrationSearch |
| Median janitor wage (federal data) | $19.75 per hour |
| State minimum wage | $16.90 |
California is the only state that makes janitorial employers themselves register with the Labor Commissioner under the Property Service Workers Protection Act, and it fines the building owner who hires an unregistered cleaner.

Why California rules move San Francisco 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 San Francisco buyer can verify before signing.
What this means in San Francisco
'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 San Francisco 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 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.
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.
How long are commercial cleaning contracts?
Twelve months is the private-sector norm, and automatic renewal is close to universal. The common evergreen wording continues the agreement for successive twelve-month periods without an 'unless you give notice' qualifier, so the exit depends entirely on a separate notice clause - commonly 30 days before the term ends. Calendar that date the day you sign.
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.
