Massachusetts Plumber License Requirements (2026)

Massachusetts licenses plumbing statewide through the Board of State Examiners of Plumbers and Gas Fitters. The usual path is licensed apprentice, then Journeyman Plumber, then Master Plumber. Current 248 CMR requirements tie the apprentice’s work experience and education together; the standard post-2008 journeyman path is 8,500 supervised apprentice hours and 550 hours of plumbing and gas-fitting theory. A master applicant needs at least one year and 1,700 hours as a Massachusetts Journeyman Plumber plus the applicable Tier Five education. Massachusetts uses its own State Plumbing and Fuel Gas Code in 248 CMR. State licensure does not issue a municipal permit: local plumbing inspectors control permit and inspection requirements.

Regulatory Body

Authority over this credential rests with Massachusetts Board of State Examiners of Plumbers and Gas Fitters (BSEPGF), which issues and polices it under M.G.L. c. 142; 248 CMR 3.00, 10.00, and 11.00. The Board regulates apprentices, journeymen, and master plumbers and gas fitters; administers examinations and licensure; and adopts the Massachusetts State Plumbing and Fuel Gas Code. Local plumbing inspectors issue and inspect local permits.

Eligibility Requirements

This guide does not establish a minimum applicant age; confirm any age requirement with the issuing authority. Check the current application for identification and tax-number requirements. Massachusetts licensure is statewide. Follow the Board’s current eLIPSE application process and the education/experience rules for the exact license level; local permits are separate.

Good moral character

Submit the current Board application and required CORI acknowledgement. This guide does not characterize a particular criminal record or prior issue as automatically disqualifying.

Background investigation

The Journeyman and Master application pages require a CORI acknowledgement form; the second page must be notarized.

Experience and Education

At least 5 years of Journeyman Plumber: the standard post-2008 path in 248 CMR 11.02 requires at least 8,500 clock hours as a licensed apprentice under the required supervision and 550 hours of theory over at least five years, completed contemporaneously as the regulation requires. Master Plumber: at least one year and 1,700 clock hours as a Massachusetts Journeyman Plumber plus the Board-approved 110-hour Tier Five program, unless that Tier Five education was completed as an apprentice. has to be evidenced and confirmed. Retain payroll, tax, project, or supervisor records, since the board may audit the experience claimed.

Accepted proof of experience or eligibility

Licensed apprentice records and current experience documentation required by 248 CMR 11.00
Journeyman application: Education Verification Form signed by a school official and Statement of Experience Form signed by the supervising master plumber
Master application: Statement of Experience and Education Verification Form with the Journeyman license number, school-official and instructor signatures
2x2 passport-style photo and notarized DOL CORI acknowledgement

Education substitution

248 CMR 11.00 contains specific credit and transition provisions, including public vocational-program credit. Use the current regulation and Board forms for any credit request; do not assume classroom education replaces supervised licensure hours.

Exam Requirements

Testing provider or authority: PSI schedules the current Massachusetts Journeyman and Master plumber examinations after Board application approval. The following examination requirements cover the pathways described in this guide; follow each part's classification, waiver, and local-scope conditions. Unpublished format details do not remove an examination requirement:

Journeyman Plumber examination — question count: confirm with the authority, timing: confirm with the authority, passing score: confirm in the current candidate bulletin
Master Plumber examination — question count: confirm with the authority, timing: confirm with the authority, passing score: confirm in the current candidate bulletin

Examination fee: The Board lists a $31 application fee, then a $52 Journeyman or $78 Master license fee payable at the test center after passing. The cited application pages do not publish a separate examination-administration fee; confirm PSI charges, if any, during scheduling.

Retake policy: The state Journeyman and Master application pages state that a failed examination may be retaken within 12 months. Follow PSI and Board instructions for the current retake process.

Insurance and Bonds

No license surety bond is mandated statewide here under the cited sources, though project-specific or public-works bonding obligations can still attach to a given job.

General liability

The cited individual-plumber application and renewal materials do not state a universal statewide general-liability minimum. A municipality, customer, insurer, contract, or business-entity filing may impose separate coverage requirements.

Workers' compensation

Assess workers’ compensation obligations separately for the business and workforce. It is not a replacement for plumbing licensure or a municipal plumbing permit.

Additional financial requirements

No financial-statement requirement is listed on the cited individual application pages. The state fee schedule lists separate $225 original and biennial renewal certificates for plumbing corporations and partnerships.

Fee Schedule

Fee	Amount
Application	$31
Initial license	$52
Renewal (every 2 years)	$52

Renewal and Continuing Education

The Massachusetts Apprentice, Journeyman, and Master Plumber Requirements must be renewed every 2 years. The fee to renew is presently $52. Renewal applications are online through eLIPSE. The Board lists a $57 late fee for renewals received after May 1; check the current renewal notice and status for the exact deadline.

Continuing education: Journeyman and Master plumbers each need 12 hours of Board-approved plumbing continuing education before renewal. The $52 displayed fee is the current Journeyman renewal; Master renewal is $78.

Reciprocity

Massachusetts grants no NASCLA reciprocity for this classification.

Reciprocal State	Accepted Exam	Conditions
No formal bilateral reciprocity agreements identified.

Do not assume reciprocity from an out-of-state plumbing credential. Use the Board’s current substantially-equivalent-license policy and application instructions for any out-of-state request.

Step-by-Step Application Roadmap

Obtain and maintain an apprentice plumber license. Work as a licensed apprentice under the supervision required by 248 CMR. Preserve the employer and education records the Board will require for the Journeyman application.
Complete the Journeyman education and experience path together. For the standard post-2008 path, complete 8,500 hours of qualifying supervised apprentice work and 550 hours of approved theory over at least five years, observing the regulation’s contemporaneous education/work rules.
Apply online for the Journeyman examination. Apply through eLIPSE with the signed Education Verification Form, supervising-master Statement of Experience Form, passport-style photo, notarized CORI acknowledgement, and $31 application fee.
Pass the Journeyman examination and pay the license fee. After Board approval, schedule through PSI. On passing, pay the $52 Journeyman license fee at the test center under the current state application page.
Gain the required Journeyman experience for Master. Document at least one year and 1,700 clock hours as a Massachusetts Journeyman Plumber and complete the 110-hour Tier Five education when it was not already completed as an apprentice.
Apply for and pass the Master examination. Submit the Master experience/education form, photo, notarized CORI acknowledgement, and $31 application fee; after passing, pay the $78 Master license fee at the test center.
Obtain the local plumbing permit before work. Massachusetts explains that only a licensed master or journeyman with proper permits issued by the local plumbing inspector may perform plumbing work at a home or business. Confirm the local permit holder, filing, and inspection sequence.
Renew and complete continuing education. Journeyman and Master plumbers renew online on the state cycle. Each must complete 12 hours of Board-approved plumbing continuing education before renewal.

Common Filing Mistakes

These are the recurring mistakes that most often delay or reject a Massachusetts Plumber application, based on the official instructions cited here.

Using outdated three-year/300-hour rules

Older consumer materials and transition rules can be misleading. The standard post-2008 Journeyman path is governed by current 248 CMR 11.00 requirements.

Treating education and work hours as independent

248 CMR ties the apprentice education and experience progression together. Preserve records and follow the contemporaneous-completion rule.

Assuming gas-fitter licensing is needed in addition to a plumber license

Massachusetts says licensed master and journeyman plumbers may perform gas-fitter work; the reverse is not true. Check the exact scope and permit before work begins.

Calling state license approval a plumbing permit

Municipal plumbing inspectors issue local permits and conduct inspections. State licensure does not authorize work without the local permit process.

Relying on a generic national plumbing code

Massachusetts publishes and enforces 248 CMR. Use the current Massachusetts materials for work, examination, and code interpretation.

Frequently Asked Questions

Does Massachusetts use the IPC or UPC?

Massachusetts uses its own State Plumbing and Fuel Gas Code in 248 CMR. Use the current Board-published code and regulations rather than assuming an IPC or UPC rule applies.

What does the standard Massachusetts Journeyman plumber path require?

For apprentices licensed on or after September 1, 2008, 248 CMR’s standard path requires 8,500 hours of qualifying supervised apprentice work and 550 hours of theory over at least five years, with education and work completed contemporaneously as the regulation requires.

What is required to become a Master Plumber?

A Massachusetts Journeyman Plumber must document at least one year and 1,700 hours of qualifying experience and complete the 110-hour Tier Five program if it was not already completed as an apprentice, then pass the Master examination.

Can a Massachusetts plumber perform gas-fitting work?

Yes. The Board’s consumer fact sheet says a licensed master or journeyman plumber may perform gas-fitter work; a master or journeyman gas fitter may not perform plumbing work.

Do state licenses replace local plumbing permits?

No. State licensure is separate from municipal permitting. Massachusetts states that licensed plumbers still need proper permits issued by the local plumbing inspector for work at a home or business.
