Contractor licensing

Maine contractor license requirements

Maine does not license general contractors or home contractors at the state level. It licenses specific trades, regulates home construction contracts over $3,000, and leaves building permits to towns.

There is no statewide general contractor license in Maine. The Maine Attorney General's office says it plainly: Maine does not license or regulate home contractors. You can start building decks, framing additions, or running a remodeling company without a state contractor license. What Maine does regulate is the paperwork and the trades. Any home construction contract over $3,000 must be in writing with specific terms set by statute, and electrical, plumbing, and oil, gas, and solid fuel work all require individual state licenses through the Office of Professional and Occupational Regulation (OPOR).

Why there is no Maine general contractor license

Maine has debated a home contractor license for years. The most recent attempt, LD 1226, would have required a license for anyone working on residential construction projects over $15,000 and set up a board to oversee the program. It passed both the House and the Senate along party lines, but local reporting on April 16, 2026 confirmed it was not taken up by the Appropriations and Financial Affairs Committee at the end of the session, which effectively killed it for lack of funding. Some contractor guides online still describe LD 1226 as enacted. It was not. Expect the idea to come back, and check the legislature before assuming the rules below still hold.

The Attorney General notes that its Consumer Mediation Program gets more complaints about contractors than any other category of business. That is the backdrop for the contract law below, and it is why many homeowners will ask for references and a written contract even on small jobs.

The $3,000 home construction contract rule

Title 10, section 1487 of the Maine Revised Statutes is the closest thing Maine has to a residential contractor law. Any home construction contract for more than $3,000 in materials or labor must be in writing, signed by both the contractor and the homeowner or lessee, and both must get a copy before work begins. The contract must contain the entire agreement and at least these parts:

  • Names, addresses, and phone numbers of both parties, and the location of the work.
  • Estimated start date and estimated substantial completion date.
  • Total contract price, or for cost-plus work, the agreed price and an estimate of labor and materials.
  • Method of payment, with the initial down payment limited to no more than one third of the total price.
  • A general description of the work and materials.
  • The statutory warranty statement, word for word, covering faulty materials, building code compliance, and skillful construction.
  • A dispute resolution clause offering binding arbitration, nonbinding arbitration, or mediation, in addition to small claims.
  • A change order statement: any change that revises the price is done only by written change order.
  • Insulation disclosures when insulating an existing home, and an energy standards statement for new homes and additions.
  • The Attorney General's consumer protection information as an addendum, plus a notice pointing homeowners to the AG website.

The Attorney General publishes a model home construction contract that meets these requirements. A homeowner can waive the statutory terms, but only after the contractor specifically explains those rights and the homeowner agrees in writing. Say a two-person crew signs a $24,000 roof replacement. The deposit can be no more than $8,000, the warranty language has to be in the contract, and any added sheathing replacement that changes the price needs a written, signed change order. The remodeling contract guide covers the rest of a solid residential contract.

Trades that do need a Maine license

If your company self-performs regulated trade work, someone on the crew needs the right individual license. A general contractor without its own licensed electrician or plumber subs that work out.

  • Electrical: the Electricians' Examining Board licenses master, limited, journeyman, apprentice, helper, and journeyman-in-training electricians, issues electrical permits, and handles a single-family dwelling certification. Licenses renew every two years based on the first licensure date.
  • Plumbing: the Plumbers' Examining Board examines and licenses plumbers. Since January 1, 2024, all applications, exams, and renewals go through its online system, and exams are given through PROV, Inc.
  • Fuel systems: the Maine Fuel Board licenses oil and solid fuel burner technicians (master, journeyman, apprentice), propane and natural gas technicians, limited tank installers, limited energy auditors, and limited wood pellet technicians.
  • Door-to-door home repair: a transient seller who solicits home repair door to door without a permanent place of business in that town must hold an OPOR license. The fee is $30 plus a $21 State Police background check, and the license renews annually on April 30.

How to check a Maine contractor

For electricians, plumbers, and fuel technicians, use OPOR's online license search; the Plumbers' Examining Board notes verifications are free through its online portal and OPOR does not issue paper verifications. For general and home contractors, there is no license to look up. The Attorney General's Consumer Protection Division will tell you whether a contractor has been the subject of consumer complaints (1-800-436-2131), and the AG lists contractors the state has sued. For subs on your own jobs, collect a certificate of insurance and the trade license numbers before they mobilize.

Without a state license system doing the screening, a GC's own prequalification matters more. Track each sub's trade license, insurance expiration, and Maine lien rules deadlines in one place. Smart Business Automator's subcontractor compliance automation keeps those records current per job. If you also work across the border, check the New Hampshire contractor license rules separately.

Frequently asked questions

Do you need a contractor license in Maine?

Not for general or home contracting. Maine does not license home contractors. You do need individual licenses for electrical, plumbing, and oil, solid fuel, propane, and natural gas work, and door-to-door home repair sellers need an OPOR license.

Did Maine pass a home contractor licensing law?

No. LD 1226 would have required a license for residential projects over $15,000. It passed both chambers but was not funded by the Appropriations Committee and died at the end of the session in April 2026.

What does a Maine home construction contract need?

Contracts over $3,000 must be written and signed, and must include work dates, price, payment terms with a deposit of no more than one third, a work description, the statutory warranty, a dispute resolution choice, a written change order clause, and the AG's consumer protection addendum.

How do I look up a Maine contractor license?

Trade licenses such as electrician, plumber, and fuel technician can be checked through OPOR's online license search. Home contractors are not licensed, so contact the Attorney General's Consumer Protection Division to ask about complaints.
