State rules
Plumbing in Massachusetts: licenses and permits
Licensed plumbers only. In Massachusetts, plumbing work in your home must be done by a master or journeyman plumber licensed by the Board of State Examiners of Plumbers and Gas Fitters. A licensed plumber may also do gas fitting; a licensed gas fitter may not do plumbing (state consumer fact sheet).
Local permits. Before plumbing or gas work is installed, altered, replaced or repaired, the local plumbing and gas inspector must issue a permit. Permits go only to licensed individuals, never apprentices, and the inspector inspects permitted work (248 CMR 3.05).
The code. The state plumbing code is 248 CMR 10.00, the Uniform State Plumbing Code; the current edition took effect December 8, 2023 (248 CMR 10.00).
Contractor registration. Licensed plumbers working only within their license are exempt from home improvement contractor registration (201 CMR 18.01).
Lead service lines. Community public water systems had to submit a service line inventory by October 16, 2024, and MassDEP is posting the submissions on an interactive map as it reviews them (MassDEP).
Gas safety. If you smell gas inside, leave right away and call 911 once you're outside (state guidance).

FAQ
Massachusetts plumbing questions
Can a homeowner do their own plumbing in Massachusetts?
State law says only licensed master or journeyman plumbers may do plumbing work, and plumbing permits are issued only to licensed plumbers. The state's consumer fact sheet lists no homeowner exception.
Which plumbing jobs don't need a permit?
Repairing a leak in a faucet, valve or other working part of a fixture, clearing a stoppage, and adjusting gas appliance controls. Replacing or moving fixtures and piping needs a permit.
Do Massachusetts plumbers need home improvement contractor registration?
Not for plumbing alone. The state's home improvement contractor rules exempt licensed plumbers working only within the scope of their license.
How do I check a plumber's license?
Use the state's license lookup on mass.gov, searching by license number or name. It lets you check the license's status.
Is there a charge to use New England Plumbers?
No. The call and the referral are free to homeowners. Any estimate and any work are agreed directly between you and the contractor.
