Michigan Contractor LLC: Licensing, Insurance, and Liability for Builders and Trades

If you build, remodel, wire, plumb, or install for a living in Michigan, forming an LLC is almost always the right move — but the entity by itself does very little for you. A Michigan contractor LLC gives you a liability shield under the Michigan Limited Liability Company Act (MCL 450.4101 et seq.), a clean name to put on contracts and trucks, and a structure that lets you bring on partners or employees. What it does not do is make you licensed, make you insured, or protect you from the two liabilities that actually sink Michigan contractors: unpaid subs and suppliers under the Builders Trust Fund Act, and your own hands-on negligence on a jobsite.

This guide walks through the sequence that works: the license question first, the filing second, then the insurance and liability structure that makes the LLC worth having.

Get the licensing question straight before you file

Michigan does not have one “contractor’s license.” It has several separate licensing regimes, mostly administered by LARA’s Bureau of Construction Codes, and which one applies depends on the work you actually perform.

Work you do	License you need	Governing law / board
Building or structurally remodeling homes (up to 3 units per structure)	Residential Builder	Occupational Code, Article 24 (MCL 339.2401 et seq.), Residential Builders & M&A Contractors Board
Siding, roofing, gutters, decks, painting, drywall, tile, basement waterproofing, insulation, excavation	Maintenance & Alteration Contractor (licensed by trade classification)	Same Article 24 board
Electrical work	Electrical Contractor license, held through a Master Electrician	Electrical Administrative Act
Plumbing work	Plumbing Contractor license, held through a Master Plumber	State Plumbing Act
HVAC, refrigeration, ductwork, hydronic heating	Mechanical Contractor license, by classification	Forbes Mechanical Contractors Act
Commercial-only construction (non-residential)	No state builder license required, but local permits and trade licenses still apply	Local building departments
Lawn care, cleaning, handyman odd jobs below the statutory threshold	Generally no state license	—

Two things trip people up here. First, “handyman” is not a license category — if the work falls into an M&A classification, you need that classification regardless of how small the job is, with only narrow statutory exemptions. Second, if you’re doing residential work at any real scale and you’re unlicensed, MCL 339.2412 bars you from bringing a lawsuit to collect what you’re owed. You can do the work, get stiffed, and have no court remedy. No entity structure fixes that.

If you’re still deciding whether to operate as a company at all, our comparison of an LLC versus a sole proprietorship in Michigan covers the tradeoffs for small trade operators, and our guide to LLCs for contractors goes deeper on day-to-day operations.

The qualifying officer rule most contractors learn the hard way

Here is the detail that causes the most rework: a Michigan residential builder or M&A license issued to an individual does not transfer to your LLC.

When a company holds the license, LARA issues it to the company and designates a qualifying officer — a person who has passed the exam and completed the prelicensure education (a 60-hour course for new applicants), and who is a member, officer, or employee with actual authority in the business. The qualifying officer’s name and the company license are linked in LARA’s records.

Practical consequences:

If you already hold an individual license and then form an LLC, you must apply to LARA for a company license with yourself as qualifying officer. Signing contracts in the LLC’s name while only you personally are licensed is a compliance problem.
If your qualifying officer leaves the company, the company license is compromised until you designate a replacement. If your qualifying officer is a partner who owns 50% and walks out mid-project, you have an operational crisis, not just a paperwork problem. Address this in your operating agreement.
The LLC name on your license, your Articles of Organization, your certificates of insurance, and your contracts should all match exactly. Mismatches cause permit delays at the local building department and denied insurance claims.

Because of how Michigan defines “professional service,” residential builders and the trades form standard LLCs — not PLLCs. Architects, engineers, and surveyors on the design side are the ones who need a professional entity.

Filing your Michigan contractor LLC

The filing itself is the easy part. Everything goes through LARA’s MiBusiness Registry Portal.

Pick and check a name. Under MCL 450.4204, the name must include “Limited Liability Company,” “L.L.C.,” or “LLC,” and must be distinguishable from existing Michigan entities. Search the business entity database before you print anything. If you brand as “Thumb Coast Roofing” but the entity is “TC Exteriors LLC,” file an assumed name (DBA) so the brand is legally tied to the entity.
Appoint a resident agent with a Michigan street address. MCL 450.4207 requires a resident agent and registered office in Michigan — no P.O. boxes. If you’re a contractor who is on jobsites all day, using your home address means service of process and LARA mail land wherever you aren’t. Our Michigan registered agent explainer covers the tradeoffs.
File Articles of Organization (Form CSCL/CD-700). The filing fee is $50 under MCL 450.4203. Optional 24-hour expedited processing is an additional $50, which is worth it when a general contractor wants your entity and COI before Monday.
Write an operating agreement. Michigan doesn’t require one, but for a contracting business it should address who the qualifying officer is, how draws work against progress payments, what happens on a callback or warranty claim, and buyout terms. Two-partner trade businesses without one end up in court over a truck and a customer list.
Get an EIN. You need it for payroll, for supply house accounts, and to open a business bank account. If you’d rather not deal with the IRS portal, we offer EIN filing as a service.
Open a dedicated business bank account immediately. This matters more for contractors than almost anyone else — see the trust fund discussion below.

What the LLC actually protects — and what it doesn’t

Under MCL 450.4501, members aren’t personally liable for the debts and obligations of the company solely by virtue of being members. That’s real protection, and it’s the reason to file. But contractors face several liabilities that reach through the entity, and knowing which is which tells you where to spend your risk-management dollars.

The LLC generally protects you from:

A breach-of-contract claim by an owner over the LLC’s work
A supplier’s or lender’s claim on a business debt you did not personally guarantee
Vicarious liability for an employee’s negligence on a job
A judgment exceeding your insurance limits, to the extent it’s a company obligation

The LLC does not protect you from:

Michigan Builders Trust Fund Act liability (MCL 570.151 et seq.). This is the big one. Money a contractor or subcontractor receives from an owner for a building project is held in trust for the laborers, subcontractors, and materialmen on that project. Using Job A’s deposit to cover Job B’s payroll, or to pay yourself, is a misappropriation — and it creates personal liability for the officers and members who directed it, plus potential criminal exposure. Every year Michigan contractors discover that “the LLC took the money” is not a defense. Separate accounts, job costing, and paying suppliers out of the job they belong to are not accounting niceties here; they’re the difference between a business debt and a personal one.
Your own negligence. If you personally miscut a roof truss or leave an unsecured trench and someone is hurt, you can be named individually. The LLC doesn’t erase personal tort liability — insurance does.
Personal guarantees. Lumber yards, equipment lessors, and bonding companies routinely require the owner’s personal guarantee on new accounts. Read what you sign; ask to have the guarantee removed after a payment history is established.
Unlicensed work. Operating outside your license classification exposes you personally to LARA discipline, and MCL 339.2412 still bars collection.
Unpaid payroll and sales/use taxes. Responsible-person liability follows the individual.

The insurance stack a Michigan trade business actually needs

The LLC and the insurance policy are complementary, not substitutes. General contractors and homeowners will ask for a certificate of insurance long before they ask for your Articles of Organization.

General liability. Required in practice by virtually every GC and most municipalities for permitting. A $1 million per-occurrence / $2 million aggregate limit is the common ask. Confirm your policy doesn’t carry a residential construction exclusion — some carriers write them for new home builders.
Additional insured endorsements. GCs will require you to add them as additional insured, often with primary and non-contributory wording. Understand what you’re agreeing to in the subcontract’s indemnity clause before your COI goes out.
Commercial auto. A personal auto policy will deny a claim on a work truck used in business. If you have a wrapped van hauling tools and materials, you need commercial auto.
Tools and equipment / inland marine. Covers tools stolen from the jobsite or the truck — a routine loss in this trade, and not covered by general liability.
Builder’s risk. Course-of-construction coverage on the structure itself, usually project-specific.
Workers’ compensation. Michigan requires coverage when you have one employee working 35 or more hours per week for 13 or more weeks in a year, or three or more employees at any one time (MCL 418.115). Critically, in construction, hiring an uninsured subcontractor can make you responsible for that sub’s employees. Collect a current certificate from every sub, every year, without exception.

Ongoing compliance: the February 15 deadline

Every Michigan LLC must file an annual statement with LARA by February 15, with a $25 fee. Miss it repeatedly and your LLC can fall out of good standing — which is exactly the moment a title company, a bonding agent, or a general contractor pulls your entity record and finds it. February is also when many contractors are least focused on paperwork. If you’d rather it simply happen, we handle annual statement filing on an ongoing basis.

Two other registrations belong on the list:

Sales and use tax. Michigan generally treats contractors as the consumers of materials they affix to real property, meaning you pay sales or use tax on your material purchases rather than charging it to the homeowner. If you also sell tangible goods that don’t become part of the realty — appliances, freestanding fixtures — you likely need a sales tax license from Treasury. Talk to a Michigan CPA about how your specific mix is treated.
Unemployment insurance. Register with the Unemployment Insurance Agency once you have employees.

Once the entity and licensing are in place, the next constraint on a contracting business is lead flow. A verified Google Business Profile with service-area settings and real project photos is the single highest-return marketing step for trades, and a simple contractor website with your license number and service area closes the loop for homeowners who check before they call.

Frequently Asked Questions

Do I need a residential builder license if I form an LLC? The LLC and the license are separate requirements — forming one does nothing for the other. If your work falls under Article 24 of the Occupational Code, the LLC itself must hold a company license with a designated qualifying officer, and you should apply to LARA for that company license rather than relying on an individual license.

Can I move my existing individual builder license to my new LLC? Not automatically. You apply to LARA for a license in the company’s name and list yourself as the qualifying officer; your individual qualifications carry over, but the company license is a distinct credential. Do this before you start signing contracts in the LLC’s name.

Will an LLC protect me if I don’t pay my subcontractors? No. Under the Michigan Builders Trust Fund Act (MCL 570.151 et seq.), project funds are held in trust for subs and suppliers, and misappropriating them creates personal — and potentially criminal — exposure for the individuals who directed the payments. Keep job funds segregated and pay each job’s suppliers from that job’s receipts.

How much does it cost to start a contracting LLC in Michigan? The state filing fee is $50, with optional 24-hour expedited processing for an additional $50, plus $25 every year by February 15 for the annual statement. Licensing fees, prelicensure education, insurance, and bonding are separate and typically dwarf the formation cost — our cost calculator breaks out the realistic first-year total.

Should a one-person trade business bother with an LLC? Usually yes. Construction work carries real bodily-injury and property-damage exposure, general contractors often won’t hire an unincorporated sub, and the separation between business and personal assets matters most in exactly the trade where things fall, leak, and burn.

If you’re ready to get the entity in place so you can move on to licensing and insurance, we file Michigan LLCs through the MiBusiness Registry Portal with the state fee included and expedited processing available.
