This overview is for educational purposes only and is not legal, tax, or insurance advice. Coverage terms and availability vary by state, carrier, and risk.

Michigan licenses residential builders, tests them, and requires continuing education. What it does not do is make you carry liability insurance to hold that license.

Your contracts do, and so does the practical reality of the work. Michigan also has a rule that costs unlicensed builders more than any premium ever would: work without the license and you lose both your lien rights and your ability to sue for payment.

Does Michigan Require Contractors to Carry Insurance?

Workers' compensation, at certain thresholds. General liability, not as a licensing condition.

Requirement Who it applies to What it means
Residential Builder or Maintenance and Alteration license Anyone contracting residential construction or remodeling at $600 or more, including labor and materials Prelicensure coursework, exam, and continuing education through LARA. No general liability mandate and no state license bond
Workers' compensation Employers meeting the thresholds in MCL 418.115 Generally triggered at three or more employees at any one time, or one employee working 35 hours or more per week for 13 weeks or longer
Trade licenses Electrical, mechanical, and plumbing contractors Separate licensure through their own boards, with their own conditions
Local registration Contractors pulling permits in Detroit, Grand Rapids, Lansing, Ann Arbor, and elsewhere City requirements that often include their own insurance and bond conditions
Your contract Anyone bidding commercial or subcontract work Typically $1 million per occurrence and $2 million aggregate, plus endorsements

Michigan has no statewide license for commercial general contracting. A Residential Builder may do new homes and most repair work, while plumbing, electrical, and mechanical scopes require their own licenses regardless. Confirm current requirements with LARA before you renew.

Two Michigan Licensing Claims That Are No Longer True

The Homeowner Construction Lien Recovery Fund no longer exists. Michigan abolished it in 2010 after the fund ran out of money, yet some sites published this year still list a Recovery Fund assessment among Michigan licensing costs. There is no such contribution to budget for, and no fund standing behind a homeowner's claim against you.

There is no $100,000 general liability minimum under MCL 339.2412. That figure circulates with that citation attached, and the citation gives the game away. Section 339.2412 is the statute barring unlicensed builders from suing for compensation. It says nothing about insurance limits.

Both errors point the same direction, which is that Michigan asks less of you at the licensing counter than most states and more of you in the contract. Plan around the contract.

Working Unlicensed Costs You the Lien and the Lawsuit

Under MCL 339.2412(1), a residential builder or maintenance and alteration contractor cannot bring or maintain a court action to collect compensation without proving they were licensed while the work was being performed. An unlicensed builder also has no construction lien rights on the project.

The Michigan Supreme Court has clarified how far that reaches. Contracts with an unlicensed builder are voidable by the homeowner rather than void from the outset; the statute operates as a shield for the public rather than a sword; homeowners get no independent cause of action from it; and an unlicensed builder can still defend a claim brought against them. What they cannot do is go get paid.

Residential contracts carry their own formality too. Michigan's Construction Lien Act requires the written contract to state that the builder or trade contractor is licensed, and to include the license number, in type no smaller than the body of the contract.

None of this is insurable. It sits in the same category as a defective contract, outside anything a liability policy responds to.

What the Contract Requires

Four items decide whether your paperwork clears a general contractor's review.

  • A certificate of insurance (COI). A one page summary, usually an ACORD form, showing coverage was in force when issued. It is not the policy.
  • Additional insured status. An endorsement extending part of your liability coverage to the general contractor or owner for claims arising out of your work. Whether it survives closeout depends on the form, so completed operations wording deserves a close read.
  • Primary and noncontributory. Language saying your policy responds first without asking the other carrier to contribute.
  • Waiver of subrogation. Your insurer gives up its right to pursue the general contractor for what it paid.

Each is a separate endorsement that must be requested, issued, and priced. Some carriers include them at bind, others decline particular combinations on residential work.

Why Michigan Contractors Get a COI Rejected

  • The entity name on the certificate does not match the licensed entity, which matters here because a company needs its own license even when the owner holds one personally.
  • Additional insured is checked with no endorsement form number, so compliance staff cannot confirm what was granted.
  • Limits arrive at $1 million aggregate when the contract asked for $2 million, or asked for it per project.
  • The certificate holder is a city registration office when the general contractor expected their own name.
  • The description of operations is blank, or an exclusion conflicts with the scope of work.

What Michigan Contractor Insurance Costs

Contractor general liability is generally rated per $1,000 of gross receipts or payroll, with the class code setting the rate. That mechanism sits behind every quote you receive.

As an illustration, a painting contractor rated at $10 per $1,000 of receipts, running $400,000 in annual receipts, sees a base premium near $4,000 before credits, debits, minimum premiums, and endorsement charges. Change the class code and the rate can double or halve. This shows the arithmetic and is not a quote.

The ranges below reflect what we commonly place for Michigan contractors with modest receipts and clean loss history.

Trade Typical annual GL range What moves the number
Handyman $600 to $1,500 Scope breadth, whether roofing is touched
Painting $750 to $2,200 Interior versus exterior, lead-safe practices
Electrical $900 to $2,900 Service upgrades, older housing stock
Plumbing $1,200 to $3,000 Freeze losses, repipe and sewer work
HVAC $950 to $3,200 Rooftop access, hot work operations
Insulation $970 to $3,800 Spray foam operations, attic and crawlspace work
Framing $1,600 to $8,000 Multi-unit exposure, story count
Roofing and siding $2,500 to $13,000 and up Limited market, ice dam and storm losses, height

Two Michigan factors matter. Winter is one: ice damming, freeze losses, and a compressed building season concentrate both claims and receipts into fewer months, which affects how carriers view seasonal payroll swings. Commercial auto is the other. Michigan's no-fault system makes auto coverage work differently here than in neighboring states, and it is worth reviewing your vehicle schedule and limits rather than rolling last year's forward.

Then there is the audit. Most general liability policies are audited after the term, and receipts above projection generate a bill. Subcontracted cost is the trap: with no certificate for a sub you paid, auditors commonly rate that spend at your own class code. Collect certificates before the first payment, and see verifying subcontractor insurance and how a general liability audit works.

Coverages We Place for Michigan Contractors

Michigan Contractor Insurance by Trade

Class code drives eligibility as much as price, and exclusions differ more by trade than most owners expect.

Before assuming a scope is covered, check common GL exclusions by trade.

Where Michigan Contractors Should Start

Check whose name is on the license. If the company signs contracts but the license sits with an individual, that gap is worth closing before it costs you a collection action, and it is far more urgent than anything on your declarations page.

We are an independent brokerage placing coverage for Michigan trades, and a policy review costs nothing. Browse our commercial insurance products or the broader contractor insurance overview.
