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 Iowa charges in sales tax, whether it licenses cleaning companies at all, and what its wage floor does to Plainfield 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.
Iowa taxes cleaning services only in part, and the split usually falls exactly where Plainfield business buyers sit - Janitorial and building maintenance/cleaning is an enumerated taxable service, NON-RESIDENTIAL only..
Most states do not license commercial cleaning companies, which surprises buyers who assume a board exists to check - in Plainfield that means insurance certificates, a written scope and real references do the verifying that a licence would elsewhere.
Iowa janitors and cleaners earn a median of $17.01 an hour per federal wage data, which is the labor floor under every Plainfield 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 Iowa 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 Plainfield quote. All three are below with official sources.

What Iowa adds to a cleaning contract
| Question | Iowa answer |
|---|---|
| Sales tax on commercial cleaning | Partly - depends on the work - Janitorial and building maintenance/cleaning is an enumerated taxable service, NON-RESIDENTIAL only. Exempt: janitorial work in a private residence paid by the occupant, and cleaning tied to new construction, reconstruction, alteration, expansion or remodeling. (Iowa Code 423.2(6)'z'; Iowa Admin. Code r. 701-211.23) |
| Median janitor wage (federal data) | $17.01 per hour |
| State minimum wage | $7.25 |
Iowa taxes commercial janitorial work as an enumerated service but exempts cleaning of a private residence paid by the occupant, and exempts cleaning performed in connection with new construction or remodeling.

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

Common questions
Is it cheaper to pay hourly or per square foot?
Neither is inherently cheaper; they suit different jobs. Hourly pricing runs $25-$75 per worker per hour and fits small or irregular scopes. Square-foot pricing fits predictable routine work and makes budgeting easier. The only fair comparison is to ask every bidder for the all-in monthly total on identical scope and frequency, then divide.
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.
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.
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.
