M.G.L. c. 142, § 3 prohibits engaging in business as a master plumber, or working as a journeyman or apprentice plumber, without a license — and also bars advertising regulated work without one. Licenses run two years and renew on or before May 1 (c. 142, § 6); the Board opens renewals February 1 of each even-numbered year. Journeyman and master plumbers complete 12 hours of approved continuing education per renewal; gas fitters complete 6.
Current Board fees: journeyman plumber $31 application + $52 license; master plumber $31 application + $78 license; renewals $52 (journeyman) and $78 (master); corporation or partnership renewal $225; late renewals add $57. Plumbing businesses organized as corporations or LLCs must name a licensed master plumber as an officer or manager. The Uniform State Plumbing Code, 248 CMR 10.00, was amended effective December 8, 2023.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Licensing is statewide and licenses are valid throughout the Commonwealth (c. 142, § 6); local plumbing and gas inspectors issue permits and inspect under 248 CMR.
The local offices section below names the exact permit desk for every Massachusetts county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
All plumber and gas fitter licenses renew on one statewide cycle: renewal opens February 1 of each even-numbered year and closes May 1.
Gas fitting has its own master/journeyman/apprentice licenses (master gas fitter renewal $97); a plumbing license alone does not cover gas piping.
248 CMR 10.00 amendments took effect December 8, 2023 and apply to jobs permitted on or after that date.
