Michigan’s workers’-comp trigger is a double trip-wire. Coverage is required if you regularly employ three or more people at one time (part-timers count) — or if you employ even one person for 35 or more hours a week for 13 or more weeks in the preceding year (MCL 418.115). A cleaning company’s first full-time hire trips the second wire alone.

What Michigan Actually Requires
| Requirement | Michigan rule |
|---|---|
| Workers’ compensation | Required at 3+ employees at one time, OR 1 employee at 35+ hrs/week for 13+ weeks — MCL 418.115 |
| State cleaning licence | None — Michigan does not licence cleaning businesses; local registrations apply instead |
| Janitorial bond | Not state-mandated — commercial contracts in the Detroit and Grand Rapids markets routinely require one |
One Full-Timer Trips the Wire
Most owners memorize the three-employee half of the rule and miss the other half: a single cleaner working 35-hour weeks for a quarter of the year creates the coverage duty by herself. The two tests run in parallel, and satisfying neither is the only way to stay outside the Act. For a cleaning business, the practical reading is simple — the first steady full-time hire means a policy, and three part-timers on any one shift means a policy.
The hours test also makes seasonal math dangerous: 13 weeks is one busy season, and the look-back window is the preceding 52 weeks, not the calendar year.
What Skipping It Actually Costs in Michigan
Michigan’s statute is short and its arithmetic is not. Under MCL 418.641, operating without required coverage is a misdemeanor punishable by a fine of up to $1,000, imprisonment up to six months, or both — and the sentence that matters is the next one: “each day’s failure is a separate offense.” An uninsured season isn’t one misdemeanor; it’s ninety of them, each carrying its own fine and its own theoretical jail exposure.
The statute also leaves the uninsured employer exposed where insured competitors are shielded: an employee injured while the company is out of compliance can pursue civil damages the exclusive-remedy rule would otherwise bar. For a cleaning operation whose trigger is Michigan’s double trip-wire — three part-timers at once, or one 35-hour cleaner for thirteen weeks — the honest reading is that the policy costs less than a single week of “separate offenses.”
The Coverages Every Cleaning Business Carries Regardless
- General liability. The scratched hardwood, the bleach spot on a client’s carpet, the wet-floor slip. One cleaning-specific catch: many policies exclude damage to property in your care, custody or control — which can mean the very surface you were hired to clean. Ask the question before you buy, not at claim time.
- Janitorial (fidelity) bond. Covers employee theft from client premises — the coverage commercial clients ask for by name before handing over keys and alarm codes. No state requires it; nearly every office contract does.
- Commercial auto for the crew vehicle — a personal policy excludes business use.
- Workers’ compensation — required in Michigan at 3 employees at once, or 1 full-timer for 13 weeks.

Frequently Asked Questions
When does a Michigan cleaning business need workers’ comp?
Under MCL 418.115, when it regularly employs three or more people at one time (part-timers count), or when it employs even one person for 35 or more hours per week for 13 or more weeks during the preceding 52 weeks — whichever happens first.
Do part-time cleaners count toward Michigan’s workers’ comp threshold?
Yes — the three-at-one-time test includes part-time employees. And one employee alone triggers coverage if they work 35+ hours a week for 13+ weeks in the preceding year.
