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 New Jersey charges in sales tax, whether it licenses cleaning companies at all, and what its wage floor does to Washington 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.
New Jersey charges sales tax on commercial cleaning services, so every Washington cleaning invoice carries tax on top of the contract price - 6.625% applies to general home AND office cleaning (janitorial), including window washing, whether or not performed on a regular contractual basis..
New Jersey does not license commercial cleaning companies, so there is no state registry for Washington buyers to check - verification falls to insurance certificates, written scope and references, which is exactly why those three matter here.
New Jersey janitors and cleaners earn a median of $18.09 an hour per federal wage data, which is the labor floor under every Washington cleaning quote - labor is roughly the whole cost structure in this trade.
Cleaning is labor, and labor is priced locally. What New Jersey sets as its wage floor, and what janitors in the state actually earn at the median, explain more of the spread between Washington quotes than any vendor's sales pitch does.
The federal rules for cleaning contractors are thin; the expensive differences are state-level. Whether New Jersey 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 Washington quote. All three are below with official sources.

What New Jersey adds to a cleaning contract
| Question | New Jersey answer |
|---|---|
| Sales tax on commercial cleaning | Yes - taxable - 6.625% applies to general home AND office cleaning (janitorial), including window washing, whether or not performed on a regular contractual basis. Rug/carpet cleaning and cleaning of upholstered fabrics and draperies are also taxable. No residential-vs-commercial split. (Tax Topic Bulletin S&U-9, Business Purchases) |
| Licence or registration required | No state licence for cleaning companies - No NJ state license for janitorial or commercial cleaning. Businesses file Form NJ-REG with the Division of Revenue and Enterprise Services for a Business Registration Certificate. Home Improvement Contractor registration covers construction-type work, not routine cleaning. |
| Median janitor wage (federal data) | $18.09 per hour |
| State minimum wage | $15.92 |
New Jersey charges 6.625% sales tax on commercial janitorial and window-washing contracts and - contrary to widespread belief - gives no residential exemption, so essentially every cleaning invoice in the state carries tax.

Why New Jersey rules move Washington 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 Washington buyer can verify before signing.
What this means in Washington
A certificate of insurance proves someone had coverage on the day it printed. It confers no rights on you, it does not obligate the insurer to notify you if the policy lapses, and the limits shown may already be partly consumed. Ask for the certificate from the broker, name your entity as additional insured, and re-request it at renewal.

Common questions
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.
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.
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.
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.
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.
