Quick answer: Maine has no statewide general contractor license. The state licenses only specific trades through boards within the Office of Professional & Occupational Regulation (OPOR), part of the Department of Professional & Financial Regulation. Electricians (Electricians' Examining Board) and plumbers (Plumbers' Examining Board) must be state-licensed. There is no general HVAC contractor license, but technicians who install or service propane, natural gas, oil or solid-fuel burning appliances must be licensed by the Maine Fuel Board. General contractors, roofers, painters, carpenters, landscapers, handymen and cleaners need no state license, though any home construction contract over $3,000 must be in writing under Maine law.
The table below shows which of the common trades need a Maine state license and which do not.
Which trades need a license in Maine?
| Trade | State license required? | Licensing body |
|---|---|---|
| Plumber | Yes | State license required - Plumbers' Examining Board within OPOR. Licenses include Master Plumber, Journeyman Plumber, Journeyman-in-Training and Trainee. |
| Electrician | Yes | State license required - Electricians' Examining Board within OPOR. Licenses include Master, Journeyman, Limited, Apprentice, Helper and Journeyman-in-Training. |
| HVAC | Sometimes | No general HVAC contractor license. But installing or servicing propane, natural gas, oil or solid-fuel burning equipment requires a Maine Fuel Board license (e.g., Propane & Natural Gas Technician, Oil/Solid Fuel Technician). |
| General Contractor | No | No state general contractor license in Maine. Home construction contracts over $3,000 must be in writing (10 M.R.S. 1487), but that is a contract rule, not a license. |
| Roofer | No | No state license for roofing. Roofers must still follow the written-contract rule for home jobs over $3,000 and cannot perform licensed trade work such as electrical or plumbing. |
| Painter | No | No state license for painting. Lead-based paint (RRP) rules apply to pre-1978 housing, but general painting needs no Maine occupational license. |
| Carpenter | No | No state license for general carpentry, framing, cabinetry or remodeling - unless the job includes a licensed trade such as electrical or plumbing. |
| Landscaper | No | No state contractor license for landscaping or lawn care. Separate rules apply to pesticide application, licensed through the Maine Board of Pesticides Control. |
| Handyman | No | No state license for handyman work. A handyman cannot perform work reserved for a licensed trade (electrical, plumbing, or fuel-burning HVAC) and must use a written contract for home jobs over $3,000. |
| Cleaner | No | No state occupational or contractor license required for residential or commercial cleaning. |
"Yes" means an OPOR-issued state license is required; "Sometimes" means a license is required only for a specific scope (fuel-burning HVAC). Unlicensed trades may still need local permits or a municipal registration and must not perform work reserved for a licensed trade.
How Maine licenses the trades
Unlike many states, Maine does not issue a statewide general contractor license. Instead, it licenses a small set of individual trades through examining boards housed in the Office of Professional & Occupational Regulation (OPOR), part of the Maine Department of Professional & Financial Regulation. The two core construction trades Maine licenses are electricians (through the Electricians' Examining Board) and plumbers (through the Plumbers' Examining Board). A third board, the Maine Fuel Board, licenses technicians who work on fuel-burning equipment.
These are individual, statewide licenses tied to competency exams and experience - not business or contractor registrations. If a trade is not on the OPOR list, Maine has no state licensing scheme for it, and regulation falls to municipal permit and code-enforcement rules instead.
Electricians and plumbers: the licensed trades
Electricians must be licensed by the Electricians' Examining Board. Maine issues several classes - Helper, Apprentice, Journeyman (and Journeyman-in-Training), Limited (narrow specialties such as low-energy, sign or house-wiring), and Master - each tied to experience and exams administered for the Board. Plumbers must be licensed by the Plumbers' Examining Board, which issues Trainee, Journeyman-in-Training, Journeyman and Master Plumber licenses.
For both trades, licensure protects public safety and is a genuine legal requirement: performing electrical or plumbing work without the proper license - or hiring someone unlicensed to do it - is prohibited. Both boards require applications, renewals and exams through OPOR's online licensing system.
HVAC and the Maine Fuel Board nuance
This is the trickiest area in Maine. There is no general HVAC or mechanical contractor license - installing air conditioning, ductwork or a heat pump does not, by itself, require a state occupational license. However, the moment the work involves a fuel-burning appliance, the Maine Fuel Board steps in. Technicians who install or service propane and natural gas equipment, or oil-burner and solid-fuel equipment (furnaces, boilers, gas ranges, water heaters, wood/pellet units), must hold a Maine Fuel Board license.
The Fuel Board issues categories such as Propane & Natural Gas Technician, Master/Journeyman/Apprentice Oil Burner and/or Solid Fuel Technician, Limited Tank Installer, Limited Wood Pellet Technician, and limited energy-auditor licenses. So a heat pump install may be unlicensed, but a gas or oil furnace hookup is not. Always confirm which board covers the specific appliance before starting work.
Trades with no Maine state license
Most home-service trades in Maine are not licensed by the state at all: general contracting, roofing, framing/carpentry, painting, landscaping, handyman work and cleaning. Maine has repeatedly considered a residential contractor licensing bill (most recently LD 1226 in 2025), but as of 2025 no such license is in effect - these trades remain unlicensed at the state level.
Unlicensed does not mean unregulated. These businesses still need building permits for many projects, must follow the written home-construction-contract law, may owe local business registration, and can never cross into a licensed scope. A carpenter, roofer or handyman cannot legally do electrical, plumbing or fuel-burning appliance work reserved for a licensed technician.
The written home construction contract law
Maine's key consumer-protection rule for contractors is the Home Construction Contracts Act (10 M.R.S. 1487 et seq.). Any home construction or repair contract for more than $3,000 in materials or labor must be in writing and signed by both the contractor and the homeowner, with each party receiving a copy before work begins. The contract must include required terms such as the parties, the work and materials, the total price, a down-payment cap of one-third, warranty language, change-order procedures and dispute-resolution options.
Importantly, this is a contract requirement, not a license. It applies to all home contractors regardless of trade, and violations are enforced by the Maine Attorney General's office - but it does not turn general contracting into a licensed profession.
How to get licensed in Maine
- Identify whether your trade is state-licensed in Maine: electricians (Electricians' Examining Board) and plumbers (Plumbers' Examining Board) are, and fuel-burning HVAC work is licensed by the Maine Fuel Board.
- If you are unlicensed at the state level (general contractor, roofer, painter, carpenter, landscaper, handyman, cleaner), confirm local permit and municipal registration rules with the city or town where you will work.
- For a licensed trade, meet the board's experience and education requirements (for example, documented apprentice/journeyman hours) and apply to sit for the required competency examination.
- Apply and renew through OPOR's online licensing system, submitting fees, proof of experience and any required certificates for your license class.
- For any home construction or repair job over $3,000, put the agreement in writing with all terms required by 10 M.R.S. 1487, and give the homeowner a signed copy before starting work.

Frequently asked questions
Does Maine have a general contractor license?
No. Maine does not issue a statewide general contractor license, and roofers, framers, carpenters and painters are not state-licensed. The main legal requirement is that any home construction contract over $3,000 must be in writing under 10 M.R.S. 1487. A residential contractor licensing bill (LD 1226) was considered in 2025 but is not in effect. Cities and towns may still require permits and local registration.
Does an HVAC technician need a license in Maine?
It depends on the work. Maine has no general HVAC contractor license, so installing air conditioning or a heat pump alone does not require a state license. But if the job involves a fuel-burning appliance - propane, natural gas, oil or solid fuel - the technician must be licensed by the Maine Fuel Board. Electrical connections may also require a licensed electrician.
Which board licenses electricians and plumbers in Maine?
Electricians are licensed by the Electricians' Examining Board and plumbers by the Plumbers' Examining Board. Both boards operate within the Office of Professional & Occupational Regulation (OPOR), part of Maine's Department of Professional & Financial Regulation. Applications, exams and renewals are handled through OPOR's online licensing system.
Does a handyman need a license in Maine?
No. Maine does not license handymen at the state level. However, a handyman cannot perform work reserved for a licensed trade - electrical, plumbing, or fuel-burning HVAC work - and must provide a written contract for any home job over $3,000. Local permits may still be required depending on the project and municipality.
