Maine Doesn't License General Contractors. Here's What to Check Instead

Maine issues no license for general contractors, builders, remodelers, roofers, siders, or deck builders. The trades the state does license are plumbers, electricians, land surveyors and site evaluators, and everybody else in residential construction operates without a state credential of any kind.

That is not a scandal and it is not a loophole. It is how this state works, and once you know it you stop looking for the wrong document and start checking the four things that are actually checkable.

I match homeowners with screened general contractors in Maine, including the builders working around Portland, and this is the first thing I explain to almost everyone who calls.

What does a Maine contractor license cover?

The state licenses trades where a mistake kills somebody or destroys a property, and it stops there.

Plumbers. Master, journeyman and trainee levels, with real examinations and real continuing education. A plumber working on your project holds a number you can verify with the state.

Electricians. Same structure, same seriousness. Master, journeyman, helper. This is the license people most often confirm and the one that matters most on a renovation of an older house.

Land surveyors. Licensed and required for a boundary survey. If your project touches a property line or a setback question, this is the person whose stamp the town will want.

Site evaluators. Licensed to design subsurface wastewater systems. On any Maine property outside a sewer district, this is who sizes and designs the septic system, and their design goes to the state.

That is the residential list. There is no general contractor tier above those, no builder registration, and no state board that hears complaints about a remodeler the way a plumbing board would hear one about a plumber.

Why do people think Maine licenses builders?

The confusion is reasonable, and it comes from five places.

Other states do license builders, some of them strictly. People who moved here, or who read national advice written for a national audience, arrive expecting a registry that does not exist.

Business registration looks like licensing. A contractor registered with the Secretary of State has filed paperwork to exist as a business. That is a formality every LLC completes and it says nothing about competence.

A town permit looks like an endorsement. It is not. A building permit says the described work is allowed at that address, not that the person doing it was vetted.

Insurance gets called a license. It is the single most useful thing to verify and it is not a license, which matters because insurance can lapse in a way a license would not.

Certifications get called licenses. Manufacturer installer programs and trade association memberships are real, sometimes meaningful, and issued by private organizations rather than by the state.

None of those five is a state license and none of them can be looked up in a state registry for builders, because there is no registry for builders.

What does "licensed and insured" really mean?

You will see the phrase on trucks, on yard signs and on websites all over this state.

Read it as two claims with very different weight. The insured half is checkable and important. The licensed half, on a general contracting business in Maine, usually refers to a plumbing or electrical license held by somebody inside the company, or to a municipal business license, or to nothing at all.

It is not necessarily dishonest. Plenty of people write it because every competitor does and because it sounds like the responsible thing to say. But it is not information, and you should not treat it as any.

Ask the direct version instead. "What licenses does your company actually hold, and who holds them?" An honest builder will tell you their electrician is licensed and they themselves are not, and that answer is the correct one.

Which bill almost changed this?

A bill to require residential contractors to register or license with the state moved through the Legislature and died when the session adjourned in the spring of 2026. Similar bills have been introduced before and have not passed.

Two things follow from that. The first is practical: nothing has changed, and any advice you read telling you to look up a Maine builder's license was wrong when it was written and is still wrong.

The second is worth watching. This comes back every few sessions, and if a version eventually passes, the useful thing about it will be a complaint record you can search rather than the license itself. Until then, the record you can search is the one you assemble yourself.

What should you check instead of a license?

Four things, in the order I would do them. All four are checkable and none of them requires a state board.

Insurance, references, financial stability, and finished work. That is the whole list. It is what my ten step screening covers before I put a name in front of anybody, and it is what you should cover if you are hiring on your own.

The rest of this page is how to check each one without it becoming a second job.

How do you verify insurance properly?

Ask for a certificate of insurance sent directly from the agent or broker, naming you and your project address. Not a photograph, not a PDF forwarded from the contractor's phone, not a policy number read out over the phone.

You want general liability, which covers damage to your property, and workers' compensation, which covers an injury to somebody working on your job. Read the effective and expiration dates. A certificate is a photograph of one day and policies lapse quietly.

Sole proprietors with no employees are often exempt from carrying workers' compensation in this state. That is legal and extremely common on small residential jobs. It also means an injury on your property has no policy standing behind it, and you want to know that before the ladder goes up rather than after. There is more on both policies on contractor insurance in Maine.

Who should you call for references?

Ask for three references from work finished in the last year, and be specific about the year. Any builder can produce a happy customer from 2019.

Then actually call them, and ask two questions that get past the pleasantries. What went wrong, and how did he handle it? Every project has something. A reference who cannot name a single problem either had a suspiciously charmed job or is not a real customer.

Did the final number match the contract number, and if not, why? This is the question that separates a builder who prices honestly from one who prices low and makes it up in change orders.

Ask for a reference on a job like yours, in a house like yours. A contractor's performance on a new build says less than you would think about their performance in a hundred year old house with plaster walls.

How can you tell if a contractor is solvent?

This is the one homeowners never think to check and it causes more abandoned jobs than incompetence does.

A contractor who is using your deposit to finish somebody else's project is running a business one bad month away from stopping work on your house. You cannot audit anybody's books, but the signals are visible.

Watch for a deposit request past the legal cap, pressure to pay ahead of the schedule, suppliers who will not extend them credit, and a lumber yard bill they want you to pay directly. Any of those is a business with a cash problem.

You can also check county court records where they work for collections actions and mechanics liens. It is a free search and it takes twenty minutes.

Where can you go and look at finished work?

Photographs are marketing. Go stand in front of something.

Ask to see a finished project like yours, ideally one that is a few years old, because a kitchen looks good on day one no matter who built it. What you are looking at is how the work has aged: caulk lines, trim joints, whether the deck boards have cupped, whether the siding still sits flat.

If they are working somewhere right now, drive by. A clean, organized site with material stored properly and the ground protected tells you how they will treat your property. A chaotic one tells you the same thing in the other direction.

Which certifications actually mean something?

Some private credentials are worth something, and it is worth knowing which.

Lead safe certification is a federal requirement, not a nicety. On a house built before 1978, anybody disturbing paint for pay has to be certified in lead safe work practices, and that certification is verifiable. On an older Maine home this is the one credential I would insist on.

Manufacturer installer programs are real and they matter for one specific reason: many product warranties only hold if the installer was trained by the manufacturer. If a warranty is part of why you chose a product, ask whether the crew is certified for it and get the answer in writing.

Trade association membership means somebody paid dues and agreed to a code of conduct. It is a mild positive signal and nothing more.

Treat all three as supporting evidence. None of them replaces the four checks above.

Which permits require a licensed trade?

Here is where the licensing question stops being abstract.

Plumbing and electrical permits in Maine are pulled by the licensed trades doing that work, not by you and not by your general contractor. That means on any project involving either trade, a genuinely licensed person is signing their name to part of your job and an inspector is checking it.

That is real protection and it is worth understanding, because it tells you which parts of your project have a state backed check on them and which parts do not. The framing, the siding, the tile and the finish carpentry have no such check. Your contract and your own diligence are the check.

What your specific project requires is a question for your town's code office. Every town in Maine sets its own thresholds and they are genuinely different from each other, so ask yours rather than trusting a number you read anywhere, including here.

Why is this not as bad as it sounds?

A license is a floor, not a ceiling. In states that issue them, plenty of licensed builders do poor work, because passing an exam once and running a good job for four months are unrelated skills.

The four things you can verify in Maine are, honestly, better predictors than a license would be. Current insurance, recent references who will talk candidly, a business paying its suppliers, and finished work you have stood in front of. That is a more useful picture than a number in a database.

It just takes work, and it takes doing it before you fall in love with somebody's personality. Which is the actual failure mode here. Almost nobody gets burned because they could not find a license. They get burned because they liked the guy and skipped the calls.

Frequently asked questions

Does Maine license general contractors at all? No. There is no state license, registration or exam for general contractors, builders or remodelers in Maine. Plumbers, electricians, land surveyors and site evaluators hold state licenses.

What about roofers, siding installers or deck builders? None of those trades is licensed by the state either. They are checked the same way a general contractor is: insurance, references, financial signals and finished work.

Is it legal for someone with no credentials to build my addition? Yes, provided the work meets code and passes the inspections your town requires, and provided any plumbing and electrical is done by licensed trades. The permit and inspection process is the state backed check, not a builder's license.

How do I report a bad contractor if there is no licensing board? The Maine Attorney General's consumer protection division takes complaints about home construction and runs a mediation process. There is no trade board for builders to complain to.

Does a business registration mean anything? It means the business exists on paper. It says nothing about skill, insurance or solvency, and every legitimate and illegitimate operator alike has one.

Should I hire someone who says they are licensed? Ask what license and who holds it. If the answer is a plumbing or electrical license inside the company, that is honest and useful. If the answer is vague, you have learned something.

How do I use these checks on my network?

I run the four checks before anybody joins my network and I re-check them after. That is a screening process rather than a guarantee, and I say so plainly: insurance lapses, businesses turn, and a crew that was excellent last year can be short handed this year.

What it does mean is that the three names I put in front of you have already been through it, which saves you the part of this page that takes the longest.

Tell me what you are building and what town you are in, and I will match you with three contractors who fit. Free, and no obligation to hire any of them.
