# Massachusetts

> Contractor licensing thresholds, regulator routing, requirements, reciprocity, and license types for Massachusetts's multi-board construction regulation model.

Massachusetts layers multiple credential types across 6 regulatory bodies. A Construction Supervisor License (CSL) is required for residential and small-building work. Separate state licenses cover electrical, plumbing, and gas fitting. Home improvement contractors must register with the state. Highway contractors face prequalification on contracts over \$50,000.

<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 Massachusetts is to understand the three main credential layers: the Construction Supervisor License for building work, trade licenses for electrical and plumbing, and highway prequalification for public works.

<Tabs>
  <Tab title="Contractors" icon="hard-hat">
    <AccordionGroup>
      <Accordion title="What is a Construction Supervisor License (CSL) and when do I need one?">
        A CSL is required for anyone supervising the construction of 1-2 family dwellings or any building up to 35,000 cubic feet. The supervisor on site must hold this license. It requires 3 years of documented experience and an open-book exam on the MA State Building Code with a 70% passing score. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="How do I register as a Home Improvement Contractor (HIC)?">
        Register with the Office of Consumer Affairs and Business Regulation. The registration fee is **\$100** (waived if you hold a valid CSL). You must also contribute to a Guaranty Fund (**\$100** to **\$500** based on employee count) and carry workers' compensation insurance. All contracts over **\$1,000** with homeowners must be in writing. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="Where do I go to get licensed in Massachusetts?">
        Massachusetts has 6 separate regulatory bodies. The CSL comes from the Board of Building Regulations & Standards (BBRS). HIC registration goes through the Office of Consumer Affairs. Electrical licensing is through the Board of State Examiners of Electricians. Plumbing and gas fitting are through the Board of State Examiners of Plumbers & Gas Fitters. See [Who regulates construction](#who-regulates-construction).
      </Accordion>

      <Accordion title="How much does it cost to get a CSL?">
        The exam fee is **\$100**, the initial license is **\$150** for a 3-year term, and biennial renewal is **\$100**. Processing takes approximately 30 days. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="What are the experience requirements for an electrical license?">
        Class A Master requires 1 year as a Massachusetts Journeyman plus 150 hours of classroom instruction. Class B Journeyman requires 8,000 hours over 4+ years under a Journeyman plus 600 hours of classroom instruction plus a high school diploma. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="Can I use my out-of-state license in Massachusetts?">
        Reciprocity is very limited. Only electrical licenses (Master and Journeyman) have reciprocity, and only with New Hampshire. Plumbing and gas fitting applicants from other states may petition the Board for equivalency but must still pass the exam. See [Reciprocal agreements](#reciprocal-agreements).
      </Accordion>

      <Accordion title="What if my project requires both a CSL and trade licenses?">
        A single residential renovation may require all three: the supervisor holds a CSL, the contractor has HIC registration, and the electrician and plumber hold separate trade licenses. These are issued by different agencies and must be obtained independently. See [Construction work regulated](#construction-work-regulated).
      </Accordion>

      <Accordion title="When is highway prequalification required?">
        Prequalification is required for non-building public works contracts over **\$50,000**. There is no application fee. Prequalification is valid for 1 or 3 years. A 5% bid bond is required on public works contracts over **\$5,000**, and a certificate of eligibility is required for contracts over **\$25,000**. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="Does Massachusetts require a license for roofing work?">
        Roofing falls under the CSL system. The CSL includes a Roof Covering classification. If you are supervising roof work on 1-2 family dwellings or buildings up to 35,000 cubic feet, a CSL with the appropriate classification is required. See [Types of licenses](#types-of-licenses).
      </Accordion>

      <Accordion title="Does Massachusetts require licensing for residential work?">
        Yes. Building 1-2 family dwellings requires a CSL. Home improvement on existing 1-4 unit owner-occupied dwellings requires HIC registration. Electrical, plumbing, and gas fitting require separate trade licenses regardless of project type. See [Construction work regulated](#construction-work-regulated).
      </Accordion>

      <Accordion title="What are the plumbing license requirements?">
        Journeyman Plumber requires 6,800 hours as a licensed apprentice under a Master Plumber plus 550 hours of plumbing theory. Journeyman Gas Fitter requires 5,100 hours plus 330 hours of gas fitting theory. Out-of-state licensees can petition the Board but must still pass the exam. See [Requirements](#requirements).
      </Accordion>
    </AccordionGroup>
  </Tab>

  <Tab title="Regulators" icon="shield-check">
    <AccordionGroup>
      <Accordion title="How does Massachusetts's licensing model compare to single-board states?">
        Massachusetts is a multi-board state with 6 separate regulatory bodies. The CSL and trade licenses serve different purposes and are issued by different agencies, even though they may apply to the same project. This contrasts with states like Connecticut that centralize all licensing under one department. See [Who regulates construction](#who-regulates-construction).
      </Accordion>

      <Accordion title="How do the CSL and HIC credentials differ?">
        The CSL is issued by the Board of Building Regulations & Standards for construction supervision of new residential and small buildings. HIC registration is through the Office of Consumer Affairs for home improvement on existing properties. A contractor may need both if they supervise construction and also do improvement work on existing homes. See [Construction work regulated](#construction-work-regulated).
      </Accordion>

      <Accordion title="What types of construction work are regulated at the state vs. local level?">
        Massachusetts regulates building supervision (CSL), home improvement (HIC), electrical, plumbing, gas fitting, asbestos, lead abatement, and highway work at the state level. General commercial construction without building supervision requirements may fall to local jurisdictions. See [Construction work regulated](#construction-work-regulated).
      </Accordion>

      <Accordion title="How does Massachusetts's $50,000 highway threshold compare to other states?">
        The **\$50,000** highway prequalification threshold is moderate. Maine triggers at **\$600,000**, Alabama requires prequalification for all state highway work, and many states have lower or higher thresholds. For cross-state comparison, see [Licensing thresholds](/docs/compare/licensing-thresholds).
      </Accordion>

      <Accordion title="What are the fees across credential types?">
        CSL: **\$100** exam, **\$150** initial 3-year license, **\$100** biennial renewal. HIC: **\$100** registration plus **\$100**-**\$500** guaranty fund. Highway prequalification has no application fee. Electrical and plumbing fees are set by their respective boards. See [Requirements](#requirements) for complete details.
      </Accordion>

      <Accordion title="What license classifications does Massachusetts use?">
        CSL offers 7 classifications (1 & 2 Family Dwellings, Masonry, Roof Covering, Windows/Door/Siding, Solid Fuel-Burning, Demolition, Insulation). Electrical has 4 classes (A through D). Plumbing has 12+ license types including plumber, gas fitter, and LP gas tiers. See [Types of licenses](#types-of-licenses).
      </Accordion>

      <Accordion title="How does reciprocity work in Massachusetts?">
        Reciprocity is narrow — electrical only, with New Hampshire only. Plumbing and gas fitting applicants from other states may petition for equivalency consideration but must still pass the relevant examination. See [Reciprocal agreements](#reciprocal-agreements).
      </Accordion>

      <Accordion title="What exam requirements exist across the different boards?">
        CSL requires an open-book exam on the state building code with 70% passing score. Electrical requires both work experience (up to 8,000 hours) and classroom instruction (up to 600 hours). Plumbing requires extensive apprentice hours (up to 6,800) plus theory instruction (up to 550 hours). See [Requirements](#requirements).
      </Accordion>

      <Accordion title="What are the renewal cycles across Massachusetts's boards?">
        CSL is a 3-year initial term with biennial renewal. HIC registration renews at **\$100**. Highway prequalification is 1 or 3 years. Electrical and plumbing renewal cycles are set by their respective boards. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="How does Massachusetts compare to other Northeast states in regulatory complexity?">
        Massachusetts is among the more complex, with 6 separate agencies and overlapping credential requirements on single projects. Maine has no general contractor license at all. Connecticut centralizes under one department. New York has minimal state regulation. See the [Northeast region guide](/docs/jurisdictions/regions/northeast).

## Special considerations

Different roles need different things from a Massachusetts page. Use the tab that matches your situation to see what matters most before you read the full detail below.

<Tabs>
  <Tab title="Contractors" icon="hard-hat">
    <Tip>
      Start by identifying whether your project triggers the CSL, HIC registration, or a trade license — these can overlap. A single residential renovation may require all three.
    </Tip>

    * A CSL is required for building 1-2 family dwellings and any building up to 35,000 cubic feet. The supervisor on site must hold this license.
    * Home improvement on existing 1-4 unit owner-occupied dwellings requires HIC registration. The registration fee is **\$100** (waived if you hold a valid CSL).
    * Electrical work requires a separate state license at the Master, Journeyman, Systems Contractor, or Systems Technician level.
    * Plumbing and gas fitting require separate state licenses with significant experience hour requirements.
    * Highway prequalification is needed for non-building public works contracts over **\$50,000**.
    * All homeowner agreements over **\$1,000** must be in writing.
  </Tab>

  <Tab title="Regulators" icon="shield-check">
    <Info>
      Massachusetts is a multi-board state with 6 regulatory bodies. The CSL and trade licenses serve different purposes and are issued by different agencies, even though they may apply to the same project.
    </Info>

    * The Board of Building Regulations & Standards issues the CSL for construction supervision.
    * The Office of Consumer Affairs handles HIC registration for home improvement contractors.
    * Electrical and plumbing/gas boards are separate examiners under state government.
    * The Department of Labor Standards handles all asbestos and lead abatement licensing.
    * Reciprocity exists only for electrical licenses and only with New Hampshire.

## Readiness checklist

Four things you need to confirm before you can treat Massachusetts as "ready" for a bid or an application. If any of these are unclear, you are not ready yet.

<Steps>
  <Step title="Classify the project type" icon="tag">
    Determine whether the work triggers a CSL (new residential or small building), HIC registration (existing home improvement), trade license (electrical, plumbing, gas), highway prequalification, or asbestos/lead certification. Multiple credentials may apply.
  </Step>

  <Step title="Apply the right threshold tests" icon="receipt">
    Highway prequalification on contracts over `$50,000`. Public works bid bond of 5% on contracts over `$5,000`. Certificate of eligibility for contracts over `$25,000`. Written contracts required on homeowner work over `$1,000`.
  </Step>

  <Step title="Route to the correct regulator" icon="building">
    Massachusetts has 6 regulatory bodies. The CSL comes from BBRS, HIC from Consumer Affairs, and each trade has its own examining board.
  </Step>

  <Step title="Confirm the requirement set" icon="clipboard-check">
    Confirm exams, experience hours, education hours, fees, and renewal cycles for each credential that applies. Massachusetts has detailed classroom instruction requirements for most licenses.
  </Step>
</Steps>

<Check>
  If you can identify all applicable credential tracks, confirm the threshold tests, route to the correct boards, and verify the requirement sets, you have the minimum package needed for a Massachusetts readiness check.

| Plumbing and gas fitting                      | State license required for all plumbing and gas fitting work                                                 |
| Highway / non-building public works           | Prequalification required on contracts over **\$50,000**                                                     |
| Public works (general)                        | Bid bond of 5% required on contracts over **\$5,000**; certificate of eligibility required over **\$25,000** |
| Asbestos and lead abatement                   | State license required through Department of Labor Standards                                                 |

<Note>
  A single residential renovation project may require the supervisor to hold a CSL, the contractor to have HIC registration, and the electrician and plumber to hold separate trade licenses. These credentials are issued by different agencies and must be obtained independently.
</Note>

## Reciprocal agreements

Massachusetts has limited reciprocity. Only electrical licenses carry a reciprocal agreement, and only with New Hampshire. All other trades require applicants to meet Massachusetts requirements independently.

<Info>
  Reciprocity in Massachusetts is narrow. Only electrical licenses (Master and Journeyman) are covered, and only with New Hampshire. Plumbing and gas fitting applicants from other states may petition for equivalency but must still pass the exam.
</Info>
