# Maine

> Contractor licensing thresholds, regulator routing, requirements, reciprocity, and license types for Maine's trade-specific construction regulation model.

Maine does not require a general contractor license. Instead, it regulates individual trades — plumbing, electrical, asbestos, lead abatement, and underground oil tank work — at the state level through separate agencies. Highway contractors face a DOT prequalification gate on contracts over \$600,000.

<Warning>
  Always verify statutes, fees, and application details with the live regulator before making bidding, licensing, or legal decisions.
</Warning>

## At a glance

The fastest way to orient yourself in Maine is to understand that there is no general contractor gate — regulation is trade-specific.

  <Tab title="Contractors" icon="hard-hat">
    <AccordionGroup>
      <Accordion title="Does Maine require a state license for general contractors?">
        No. Maine does not require a general contractor license at the state level. If your project involves only general construction with no regulated trade component, no state credential is needed. Check local jurisdiction requirements separately. See [Construction work regulated](#construction-work-regulated).
      </Accordion>

      <Accordion title="What trades require a state license in Maine?">
        Plumbing and electrical work always require state licenses regardless of contract value. Asbestos abatement, lead abatement, and underground oil storage tank installation and removal each have separate certification paths through the Department of Environmental Protection. See [Construction work regulated](#construction-work-regulated).
      </Accordion>

      <Accordion title="Where do I go to get a plumbing or electrical license?">
        Both plumbing and electrical licensing are handled by the Office of Professional and Occupational Regulation (OPOR) under the Department of Professional and Financial Regulation. Contact them at (207) 624-8603. See [Who regulates construction](#who-regulates-construction).
      </Accordion>

      <Accordion title="How much does it cost to get licensed as a plumber or electrician?">
        For plumbers: exam application fee is **\$25**, Master or Journeyman license fee is **\$200**, and background check is **\$21**. Biennial renewal is **\$200**. For electricians: application fee is **\$25**, Master license is **\$150**, Journeyman is **\$80**, and background check is **\$21**. Biennial renewal matches the license fee. See [Requirements](#requirements) for complete fee tables.
      </Accordion>

      <Accordion title="What are the experience requirements for a Master Plumber license?">
        You need at least 1 year or 2,000 hours as a licensed Journeyman, or at least 4 years or 8,000 hours as a licensed Trainee under a Master Plumber. See [Requirements](#requirements) for all plumbing license tiers.
      </Accordion>

      <Accordion title="Can I use my out-of-state license in Maine?">
        Reciprocity is limited to electrical licenses only. Master Electricians have reciprocity with New Hampshire and Vermont. Journeyman Electricians have reciprocity with Idaho, New Hampshire, North Dakota, Oregon, and Vermont. No reciprocity exists for plumbing, asbestos, lead, or underground tanks. See [Reciprocal agreements](#reciprocal-agreements).
      </Accordion>

      <Accordion title="When is DOT prequalification required for public works contracts?">
        DOT prequalification is required on contracts over **\$600,000**. It covers six project categories: Bridge Construction, Highway Construction, Paving, Marine Construction, Buildings, and Traffic Signals and/or Lighting. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="What are the requirements for asbestos or lead abatement work?">
        Asbestos contractors must be licensed and show evidence of employing certified abatement employees. A trade exam with a 70% passing score is required. Lead abatement contractors must employ a Maine-certified project supervisor and maintain an OSHA-compliant worker protection program. See [Requirements](#requirements) for fees and training details.
      </Accordion>

      <Accordion title="Does Maine require a license for roofing work?">
        No. Roofing falls under general construction, which Maine does not regulate at the state level. However, if the roofing project involves electrical or plumbing components, those trade-specific licenses are still required. Check local jurisdiction requirements for any additional permits.
      </Accordion>

      <Accordion title="Does Maine require a license for residential work?">
        Not for general residential construction. Maine does not license general contractors. However, any plumbing, electrical, asbestos, lead, or underground tank work within a residential project still requires the appropriate state trade license. See [Construction work regulated](#construction-work-regulated).
      </Accordion>

      <Accordion title="What underground oil tank certifications does Maine require?">
        Installers must pass an initial exam (80% passing score), complete an apprenticeship accumulating 1,000 experience points on supervised projects, and pass a final exam. Inspectors follow a separate single-exam track. Certificates are valid for two years with 8 hours of CE per cycle. See [Requirements](#requirements) for fee tables.

  <Tab title="Regulators" icon="shield-check">
    <AccordionGroup>
      <Accordion title="How does Maine's licensing model compare to states with general contractor boards?">
        Maine is a trade-licensing-only state with no central contractor board. Regulation is split across 3 agencies covering 4 distinct areas (plumbing, electrical, environmental, and highway). This contrasts sharply with states like Connecticut (single department with 10 boards) or Alabama (8 separate agencies). See [Who regulates construction](#who-regulates-construction).
      </Accordion>

      <Accordion title="How does Maine's $600,000 DOT prequalification threshold compare to other states?">
        The **\$600,000** threshold is relatively high compared to many states. Massachusetts triggers highway prequalification at **\$50,000**, while some states require prequalification for all public works contracts. For cross-state comparison, see [Licensing thresholds](/docs/compare/licensing-thresholds).
      </Accordion>

      <Accordion title="What types of construction work are regulated at the state vs. local level?">
        Maine regulates plumbing, electrical, asbestos, lead abatement, and underground oil tank work at the state level. General construction — including residential, commercial, and most specialty work — is not regulated at the state level and falls to local jurisdictions. See [Construction work regulated](#construction-work-regulated).
      </Accordion>

      <Accordion title="Which agencies handle specialty trade licensing vs. general construction?">
        OPOR under the Department of Professional and Financial Regulation handles plumbing and electrical. The Department of Environmental Protection handles asbestos, lead, and underground tank certifications. The Department of Transportation manages highway prequalification. There is no general construction oversight agency. See [Who regulates construction](#who-regulates-construction).
      </Accordion>

      <Accordion title="What are the fees across trades in Maine?">
        Fees vary significantly. Plumber and electrician licenses range from **\$80** to **\$200** with **\$25** application fees. Lead abatement ranges from **\$75** (worker) to **\$275** (contractor). Asbestos ranges from **\$50** (worker) to **\$650** (contractor). Underground tank installer initial exam is **\$200** with **\$150** certification. See [Requirements](#requirements) for complete fee tables.
      </Accordion>

      <Accordion title="What license classifications does Maine use?">
        Plumbing offers Master, Journeyman, Journeyman-in-Training, and Trainee tiers. Electrical offers Master, Journeyman, Limited (8 specialty categories), Helper, and Apprentice tiers, plus Senior designations for those over 70. Lead and asbestos each have multiple certification tiers for workers, supervisors, contractors, and inspectors. See [Types of licenses](#types-of-licenses).
      </Accordion>

      <Accordion title="How does reciprocity work in Maine?">
        Reciprocity is narrow — electrical only. Master Electricians have reciprocity with 2 states (New Hampshire, Vermont). Journeyman Electricians have reciprocity with 5 states (Idaho, New Hampshire, North Dakota, Oregon, Vermont). No reciprocity exists for plumbing, environmental trades, or underground tanks. See [Reciprocal agreements](#reciprocal-agreements).
      </Accordion>

      <Accordion title="What exam requirements exist across the different trades?">
        Electricians must meet extensive hour and education requirements (up to 12,000 hours plus 576 hours of study for Master). Plumber exams follow similar tiered experience requirements. Asbestos requires a 70% trade exam score. Underground tank installers need 80% on both initial and final exams. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="What are the renewal cycles across Maine's trades?">
        All plumbing and electrical licenses are biennial from the first licensure date. Lead and asbestos certifications require annual renewal with refresher courses. Underground tank certifications are biennial with 8 hours of CE per cycle. Highway prequalification is granted for 1 or 3 years. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="How does Maine compare to other New England states in regulatory complexity?">
        Maine is among the least complex — it has no general contractor license at all. Compare this to Massachusetts (CSL plus HIC plus trade licenses across 6 agencies) or Connecticut (10 boards under DCP). Maine's simplicity comes from delegating general construction to local jurisdictions. See the [Northeast region guide](/docs/jurisdictions/regions/northeast).

  <Tab title="Contractors" icon="hard-hat">
    <Tip>
      If your project involves only general construction with no regulated trades, Maine does not require a state credential. Start by identifying whether your work includes a regulated trade.
    </Tip>

    * Maine has no general contractor state license. General construction work is unregulated at the state level.
    * Plumbing and electrical work always require state licenses regardless of contract value.
    * Asbestos, lead abatement, and underground oil tank work each have separate certification paths through the Department of Environmental Protection.
    * Highway work requires DOT prequalification on contracts over **\$600,000**.
    * All plumbing and electrical licenses renew biennially.
  </Tab>

  <Tab title="Regulators" icon="shield-check">
    <Info>
      Maine is best understood as a trade-licensing state with no central contractor board. Regulation is split across 3 agencies covering 4 distinct areas.
    </Info>

    * The Department of Professional and Financial Regulation covers both plumbing and electrical licensing through its Office of Professional and Occupational Regulation.
    * The Department of Environmental Protection handles asbestos, lead, and underground tank certifications.
    * DOT manages highway prequalification separately from all trade boards.
    * Reciprocity exists only for electrical licenses and only with a handful of states.

## Construction work regulated

Maine does not regulate general contracting at the state level. Licensure is triggered by the type of trade work involved, not by contract value — except for highway prequalification.

## Reciprocal agreements

Maine's reciprocity is limited to electrical licenses. No statewide reciprocity arrangement exists for plumbing, asbestos, lead abatement, or underground tank work.

<Info>
  Reciprocity in Maine applies only to electrical licenses and varies by license level. Master and Journeyman licenses have different reciprocal state lists.
