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 Martinez 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 Martinez 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 Martinez 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 Martinez cleaning quote - labor is roughly the whole cost structure in this trade.
Cleaning is labor, and labor is priced locally. What California sets as its wage floor, and what janitors in the state actually earn at the median, explain more of the spread between Martinez quotes than any vendor's sales pitch does.
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 Martinez quote. All three are below with official sources.

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 Martinez 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 Martinez buyer can verify before signing.
What this means in Martinez
Cutting frequency looks like the obvious way to cut a Martinez cleaning bill, and it is the one that backfires: infrequent service raises the cleaning time a building needs by 60-70%, so the per-visit price climbs while the building gets dirtier between visits.

Common questions
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.
What does floor stripping and waxing cost?
Strip and refinish runs about $0.30-$0.80 per square foot in 2026 pricing, and scrub-and-recoat - the lighter maintenance version - about $0.20-$0.40. Most vendors apply a minimum service fee of roughly $250-$500, which makes small jobs disproportionately expensive per square foot.
What does 'bonded and insured' actually mean?
They are two different things and only one behaves like protection. Insurance - general liability, typically $1 million per occurrence, plus workers' compensation - responds to covered claims. A janitorial surety bond covers employee theft but pays only after the employee is criminally convicted, and the cleaning company must reimburse the surety afterward. It is closer to a credit guarantee than to insurance.
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.
Does cleaning less often save money?
Less than you would think, and sometimes not at all. Soil accumulates between visits, and industry measurement puts the additional cleaning time required by infrequent service at 60-70%. The per-visit price rises as frequency falls, so halving the schedule does not halve the bill - and the building looks worse in between.
