Maine Contractor License: Requirements, Cost and Exams

The qualifier rule

Qualifying individual model

The trade boards for electrical, plumbing, and fuel work license individuals directly rather than running a company license through a named qualifier, the way states like Florida or North Carolina do. A company's standing to perform licensed trade work rests on having a licensed individual of the right tier on staff, which is a staffing fact to confirm with each board rather than a qualifier filing process. Maine does not run a company qualifier model today. That could change if LD 1226 or a successor bill is enacted and funded.

What changed

Where a statewide general contractor license stands

Maine still has no statewide general contractor license. A bill that would create one, LD 1226, has not become law. News reporting shows LD 1226 cleared both legislative chambers in June 2025 but stalled on the Special Appropriations Table over a funding gap, and that as of mid 2026 it had not been enacted (wgme.com, fox23maine.com). Some vendor guides describe LD 1226 as already enacted with a January 1, 2027 effective date; that claim conflicts with the reporting above, so LD 1226 should be treated as pending, not law, until Maine Legislature shows it enacted. Confirm current bill status directly with Maine Legislature before relying on a specific effective date for a statewide license.

General building and remodeling, state level

There is no state exam for general contracting, so there is no NASCLA acceptance pathway and no statewide reciprocity question for general contracting specifically (constructionbids.ai).

The one statewide rule touching every residential job, regardless of trade, is the Home Construction Contracts Act. Once labor or materials on a home construction job pass $3,000, the contract must be in writing and signed by both the contractor and the homeowner before work starts. The written contract must include both parties' contact information, the job site address, estimated start and substantial completion dates, a statutory warranty statement, and a dispute resolution clause (Maine Legislature, Title 10 section 1487). A violation is a civil violation carrying a statutory forfeiture of $100 to $1,000 per violation, with a 2 year window to bring a claim, and a defense if the contractor shows the miss was an unintentional, bona fide error despite reasonable procedures (Maine Legislature, Title 10, Home Construction Contracts Act). This is a contract formality requirement, not a license, and it applies on top of whatever local business licensing a town requires.

Electricians, state level

Electricians are licensed statewide by the Electricians' Examining Board, inside the Office of Professional and Occupational Regulation within the Department of Professional and Financial Regulation (maine.gov/pfr/professionallicensing). The board issues tiers from Master down through Journeyman, Limited, and Helper, and its exams are administered by PROV, Inc. under a Candidate Information Bulletin published on the board's site (maine.gov/pfr/professionallicensing). Since January 1, 2024, all permit, license, exam, and renewal activity must go through the board's online portal; applications sent by fax, mail, or email are not processed and are not returned, with one narrow paper form exception for the Student Helper Electrician License as of August 2025 (maine.gov/pfr/professionallicensing).

Maine has both a statutory reciprocity path and a licensure by endorsement rule for electricians already licensed elsewhere. Under 32 M.R.S. section 1206, the board must license an applicant who holds an out of state license and has at least 8,000 hours of actively engaged electrical work, when the other state's licensing and experience standards are at least equivalent to Maine's and that state extends similar privileges back to Maine license holders; the board may also waive the standard 576 hours of study for journeyman or master applicants (Maine Legislature, Title 32 section 1206). Separately, a licensure by endorsement rule lets an applicant with an active out of state license from a jurisdiction with substantially equivalent requirements skip the exam. Board application materials list reciprocity partners by license level: journeyman level reciprocity with New Hampshire, Vermont, North Dakota, Idaho, Oregon, and Wyoming, and master level reciprocity with New Hampshire and Vermont. Those listing documents are dated 2019, and a related rule chapter was still in draft form in the materials reviewed, so confirm the current partner list and current hour requirement directly with the board. This is a trade specific reciprocity list, not a NASCLA pathway, and it has nothing to do with general contracting.

Plumbers, state level

Plumbers are licensed statewide by the Plumbers' Examining Board, also inside OPOR (maine.gov/pfr/professionallicensing/professions/plumbers-examining-board). Maine issues three individual license classes: Trainee, Journeyman, and Master. Trainee is the entry tier with no exam, while Journeyman and Master both require an exam. The official board page names PROV, Inc. as the exam administrator; at least one vendor guide names a different exam vendor, but PROV, Inc. is the vendor named on the official board page (maine.gov/pfr/professionallicensing/professions/plumbers-examining-board). The Master Plumber credential is the one that authorizes contracting for plumbing work. The board's governing statute, Title 32 chapter 49, caps trainee supervision at three trainee plumbers per master or journeyman plumber, and gives the board authority to set rules on licensing requirements, examinations, and reciprocity of licensing with similar boards in other states (Maine Legislature, Title 32 chapter 49); the specific reciprocity terms are set in board rules, so confirm current terms with the board. Vendor fee figures for plumbing licenses were inconsistent with each other and could not be verified against an official fee schedule, so confirm current fees directly with the board.

HVAC and fuel burning equipment, state level

Maine has no separate statewide HVAC contractor license. Heating and fuel burning equipment work is licensed by fuel type through the Maine Fuel Board, also inside OPOR, which licenses propane and natural gas technicians separately from oil and solid fuel burner technicians, each at Apprentice, Journeyman, and Master tiers (maine.gov/pfr/professionallicensing/professions/maine-fuel-board). The Master Oil Burner and Solid Fuel Technician license requires 4 years of licensed practical experience as an apprentice or journeyman, with at least 2 of those years at the journeyman level; courses already counted toward a journeyman license cannot be recounted toward the master requirement (Maine Legislature, Title 32 section 18132). A journeyman's permitted scope is tied to fuel oil grade and burn rate, and a journeyman must work under a master's indirect supervision with equal or higher authority (Maine Legislature, Title 32 section 18133). Out of state applicants must document hands on experience installing, cleaning, servicing, altering, and repairing the relevant equipment (Maine Legislature, Title 32 section 18132). A company that self performs this work needs at least one licensed Master Technician on staff for each fuel category it services. That staffing expectation is not stated as a flat statutory headcount rule in the materials reviewed for this page, so confirm it with the Fuel Board directly.
