How to Get a Contractor License or Registration in Maine

There is no Maine general contractor licence, and that is the official position

Maine's Office of the Attorney General publishes the answer in one sentence on its consumer help pages: "In Maine, general contractors - and trades such as roofing and framing - are not licensed or regulated." There is no application form, no board, no exam, no bond filing and no state registry number for general construction work. A homeowner cannot look you up in a state contractor database because no such database exists for your trade.

That has consequences in both directions. You can start faster and cheaper in Maine than in almost any neighbouring state, and you do not carry a renewal cycle or continuing education for the general work itself. But you also cannot use a licence number as a trust signal in your marketing, and you have no state body standing behind you when a customer disputes your work. In practice, the Maine contractors who win on trust do it with insurance certificates, references, a clean written contract and, where they hold one, a genuine trade licence they can point to.

Be careful with the word "registration" too. Maine does not register general contractors either. Registering a business entity with the Secretary of State is a completely separate thing from occupational licensure, and calling yourself "state registered" because you filed an LLC would be a misrepresentation to a customer. The Secretary of State registers corporations, nonprofit corporations, LLCs, limited partnerships and limited liability partnerships; sole proprietorships and general partnerships are not filed with that office at all.

What LD 1226 would have done, and exactly how it ended

Maine came close to changing this, and a lot of current advice online reports the near-miss as though it happened. The facts from the Legislature's own record: LD 1226, House Paper 801 of the 132nd Legislature, "An Act to Protect Consumers by Licensing Residential Building Contractors", was presented by Representative Roberts of South Berwick on March 25, 2025 and referred to the Committee on Housing and Economic Development.

The bill as introduced would have enacted a new Title 32, chapter 153, "Residential General Contractors". It would have established a Residential Construction Board inside the Department of Professional and Financial Regulation, made up of three residential general contractors, a municipal code enforcement officer, an attorney experienced in residential construction and contract law, a University of Maine System representative overseeing career and technical education, a residential architect and two members of the public, all appointed by the Governor to three-year terms. The Board would have set standards of practice consistent with the Maine Uniform Building and Energy Code, set qualification standards, examined and issued licences, and approved curricula for preparatory education.

The licensing trigger is the number people quote. Section 19803(1) would have required, "beginning January 1, 2027", that a residential general contractor be licensed to perform, offer to perform or agree to perform residential construction "With a contract price that exceeds $15,000" or "That involves 2 or more professionals licensed under this Title". Licensed electricians, plumbers, architects and professional engineers providing their own licensed services would have been exempt, as would a person providing only design services. The bill also defined a residential general contractor to exclude a subcontractor working under someone else's customer agreement.

Two enforcement provisions are worth knowing because they show what a future version would likely carry. Section 19804 would have made a violation an unfair trade practice under 5 M.R.S. section 207, imposed a civil fine of "not more than $10,000" for an intentional violation or for misrepresenting licence status, and provided that an unlicensed person who was required to be licensed "does not have a lien claim under Title 10, chapter 603 for any residential construction performed, or materials supplied to a residential construction project, during the period in which the person was not licensed". Separately, the bill would have amended 10 M.R.S. section 1487(5) to add that no more than 85 percent of the contract price could be required before substantial completion, and would have repealed the section 1489 opt-out.

It did not pass. The committee reported the bill out on May 29, 2025 on a divided Ought To Pass As Amended report, with two competing committee amendments: C-A (H-333), which added a General Fund transfer to pay for the new board, and C-B (H-334), which would have struck the title and replaced the entire licensing scheme with a resolve "Establishing a Working Group to Study the Regulation of Residential Construction Contractors for the Protection of Consumers". The Legislature's Text and Status page records the outcome as "Final Disposition: Died On Adjournment, Apr 29, 2026". None of it is law. None of it took effect. Anything you read describing a Maine contractor licence requirement as current, or as effective in 2026, is wrong.

The licences Maine does issue, and who needs them

Plumbing is licensed by the Plumbers' Examining Board. Maine issues Master Plumber, Journeyman Plumber, Trainee Plumber and Journeyman-in-Training licences. A Master Plumber is "any person licensed by the Board, to engage in, or about to engage in, the business of installing plumbing or plumbing systems"; a Journeyman "customarily performs the work of installing plumbing and drainage under the employment and direction of a master plumber"; a Trainee works under direct supervision. The experience ladder is a minimum of two years or 4,000 hours as a licensed trainee to sit for journeyman, or 2,000 hours as a journeyman-in-training within four years; and one year or 2,000 hours as a licensed journeyman, or four years and 8,000 hours as a licensed trainee, to sit for master. Master and journeyman licences are $200 plus a $21 background check, trainee $100 plus $21, and master, journeyman and trainee licences renew every two years. The journeyman-in-training licence requires plumbing coursework plus a passing exam score of 70 percent or higher and is a four-year non-renewable licence.

Electrical work is licensed by the Electricians' Examining Board, and the ladder is longer. Maine issues Master, Limited, Journeyman, Apprentice, Helper and Journeyman-in-Training electrician licences, plus senior versions of several for licensees over 70, along with electrical permits and a Single-Family Dwelling Certification. A Master Electrician may engage in "the business of installing electrical wires, conduits, apparatus, fixtures and other electrical equipment", and qualifies with "at least 4,000 hours of service as a journeyman electrician or at least 12,000 hours of experience in electrical installations" plus a 576-hour programme of study covering electricity, electronics, mathematics, controls, motors, blueprint reading and drafting, transformers and a current National Electrical Code course, with 126 hours of degree-related coursework. The master licence fee is $150.00, licences renew on a two-year cycle based on first licensure date, and renewal requires a "15 Hour current National Electrical Code course as adopted by the board".

The permit rule is the one non-electricians most often trip over. The Electricians' Examining Board states that "No electrical installation may be installed or altered unless the master or limited electrician making the installation first obtains a permit from the Board." A general contractor cannot pull that permit. There is a narrow homeowner path: a homeowner may do the wiring in a newly constructed single-family residence they occupy as their bona fide personal abode if the installation "conforms to standards of the National Electrical Code", but certification by a state or local inspector, a master electrician or a limited electrician specialising in house wiring is required before the utility energises the service.

Two more programmes complete the picture. The Maine Fuel Board licenses technicians for "propane and natural gas, oil and solid fuel burner technicians and related equipment in Maine", across master, journeyman and apprentice oil burner and solid fuel technician licences, propane and natural gas technicians, limited energy auditors, limited tank installers, limited wood pellet technicians and gas dispensing and storage permits. And the Maine CDC's Subsurface Wastewater Unit "licenses site evaluators for subsurface wastewater disposal systems pursuant to CMR 245", while running an installer certification programme it describes as voluntary rather than mandatory.

What replaces licensure: contract law, the code, and your own paperwork

Because Maine regulates the contract rather than the contractor, your compliance work moves from an application to a document you use on every job. Any home construction or repair job over $3,000 needs a written signed contract, and 10 M.R.S. section 1487 lists fourteen required elements including the parties, the location, estimated commencement and substantial completion dates, the total price or cost-plus formula, the payment method "with the initial down payment being limited to no more than 1/3 of the total contract price", a description of the work and materials, the statutory warranty, a dispute-resolution option, a change-order clause, applicable door-to-door and insulation disclosures, an energy standards statement, and the Attorney General's consumer information and contact details.

The enforcement mechanism is a consumer statute rather than a board. 10 M.R.S. section 1490 provides that "Any violation of this chapter shall constitute prima facie evidence of a violation of the Unfair Trade Practices Act, Title 5, chapter 10", and that "Each violation of this chapter constitutes a civil violation for which a forfeiture of not less than $100 nor more than $1,000 may be adjudged". A contractor who shows by a preponderance of the evidence that a violation was an unintentional error made despite reasonable compliance procedures has a defence. That last clause is a strong argument for building one contract template that covers all fourteen items and using it every time, rather than improvising.

The building code is the other half. Maine's Division of Building Codes and Standards states that municipalities with a population greater than 4,000 must enforce the Maine Uniform Building and Energy Code, that smaller municipalities may choose to, and that regardless of enforcement, "compliance with the MUBEC is mandatory and the responsibility of the owner". Since your section 1487 warranty already promises code compliance, an unenforced town is not a lower standard for you; it just moves the discovery of a defect from the inspection to the lawsuit.

Check the official page yourself before you file or sign

Maine spreads contractor rules across at least six places: the Attorney General for the home construction contract rules, the Secretary of State for the entity, Maine Revenue Services for sales and use tax, the Office of Professional and Occupational Regulation for the licensed trades, the Workers' Compensation Board for coverage, and your own town clerk and code office for assumed names and permits. No single page carries all of it.

The licensing landscape is also genuinely unsettled. LD 1226 got as far as a divided committee report before it died on adjournment on April 29, 2026, and a bill that nearly passed once tends to come back. Before you sign a contract or file anything, open the specific official page for your question, confirm the figure, and keep a dated copy of what you read. Maine.gov states that "Construction permits and inspections, including electrical and plumbing, are managed at the town level in Maine", so your town office is the last call, not the first thing to skip.
