Commercial cleaning and janitorial insurance in Colorado

Colorado filings for a cleaning company, from the capitol to the city line

Colorado keeps the state-level list short. The work is local: home-rule cities set their own taxes, and a few metro cities tax the act of working inside their limits.

The entity and the state license question

Corporations and LLCs form through the Colorado Secretary of State. Colorado has no general statewide business license and no state occupational license for commercial cleaning. Confirm current filing steps with the Secretary of State.

Sales tax: services generally aren't taxed

The Department of Revenue's Sales Tax Guide says Colorado taxes retail sales of tangible personal property, and services generally aren't taxed unless a law specifically says so. Janitorial and building cleaning aren't on that list. So you don't need a state sales tax license for cleaning fees alone, only if you make taxable retail sales of goods.

Two cautions. A bundled sale of goods and service can be fully taxable unless certain conditions are met, so list any supplies you sell separately on the invoice. And home-rule cities run their own sales taxes, which the state doesn't administer for every city. We didn't check each city's rule, so confirm with the city before you bill. The Colorado Sales Tax Guide is the place to start.

Local head taxes and city licenses

No Colorado statute aimed at janitorial employers turned up in our research. What does reach cleaning companies is the occupational privilege tax (OPT), a monthly per-worker tax some cities charge.

• Greenwood Village requires a one-time $10 OPT license from any business with employees earning $250 or more in a month working in the city. It collects $2 a month from each such employee and $2 from the employer.
• Denver also charges an OPT on work performed in the city, wherever the business is based: $4.00 a month from the employer and $5.75 a month from the employee, with the employer withholding and paying both. Owners and partners owe the employer portion even if they earn under $500 in a month. Confirm current thresholds with Denver's Treasury Division.
• Aurora repealed its OPT effective January 1, 2025.

School buildings

Under C.R.S. 22-32-109.8, anyone a school district selects for a position that doesn't need an educator license, such as a district custodian, must submit fingerprints for a state and national background check. That section covers district hires. We found no statute applying it to a contractor's crew. If you clean a school under contract, read the contract's background-check clause before you schedule anyone.

Workers' comp rules Colorado cleaning owners trip over

In Colorado, hiring a single person puts you under the comp law (C.R.S. 8-40-203). Colorado is an NCCI state, so janitorial contractors are normally rated under class 9014.

Where cleaning companies get into trouble:

• Owners who reject coverage. Under C.R.S. 8-41-202, an owner with a 10% or larger stake who also runs the company, as an officer or an LLC member, can turn down coverage by giving written notice. That's a choice to make on paper, not by leaving yourself off the application.
• 1099 cleaners. C.R.S. 8-40-202(2) starts from employment. To overcome it, the cleaner has to work free of your direction and run a real business of their own. A signed independent-contractor document with the statute's disclosures creates only a rebuttable presumption. Ask your CPA or an attorney before you set up a 1099 crew.
• Subcontracted crews. We haven't confirmed how Colorado's statutory-employer rule applies to janitorial subs, so ask your agent how your policy treats an uninsured sub, and collect certificates either way.

The Colorado Division of Workers' Compensation runs the system. Our workers' comp page for cleaning companies explains estimates and audits.

What Colorado campuses and agencies require from cleaning vendors

State institutions in Colorado tend to follow the State of Colorado's standard contract terms. Colorado Mesa University in Grand Junction publishes its contractor requirements, and they read like a checklist:

• workers' comp as required by statute, plus employer's liability
• general liability on ISO occurrence form CG 00 01 or its equivalent: $1 million each occurrence, $1 million general aggregate, $1 million products-completed operations aggregate and $50,000 any one fire
• auto liability on any auto, owned, hired or non-owned, at $1 million each accident
• the State of Colorado as additional insured on general liability and auto, with your coverage primary
• 45 days' notice by certified mail before cancellation or non-renewal
• a waiver of subrogation in favor of the State and its agencies, officers, employees and volunteers

One line catches people: if claims pull your aggregate below $1 million, you have to restore it. Ask your agent how that would work on your policy before you sign.

Private property managers write their own versions. Our guide to what cleaning contracts require explains each endorsement, and the janitorial bonds page covers clients that also want theft protection.

Three Colorado risks behind most cleaning claims

The 1099 presumption

Colorado starts from the assumption that a paid worker is an employee. If an uninsured 1099 cleaner gets hurt, the claim can come to you, and the auditor can add that pay to your comp payroll.

A cease-and-desist order

The Division of Workers' Compensation can order an employer without required comp to stop doing business. C.R.S. 8-43-409 also allows daily fines: as much as $250 per day the first time, and between $250 and $500 per day for repeat violations. For a cleaning company, a stop order means missed shifts and lost accounts.

Winter lobbies

Colorado uses modified comparative negligence (C.R.S. 13-21-111). An injured visitor can recover if their own negligence wasn't as great as yours, with damages cut by their share. Snow and ice melt tracked across a lobby your day porter just mopped is a familiar slip claim, and it lands on your general liability policy.

Colorado cities and the local detail that matters

What sets the price of cleaning insurance in Colorado

No one can quote a Colorado premium without your payroll, and we won't publish a made-up average. The biggest lever is where your crews work: Denver hours are paid at a higher floor than the rest of the state, and comp premium follows payroll. Contract terms come next, especially additional insured, primary and waiver wording and any requirement to restore an eroded aggregate.

Your price depends on the payroll in each class code, your annual sales, the kinds of buildings you clean, how much specialty and chemical work you do, the vehicles your crews drive, your claims history and the limits your contracts require.
