Do you need a license to work as a plumber in Maine?
Yes. In Maine, any individual who does plumbing or makes plumbing installations needs a license from the Plumbers’ Examining Board, except for work that needs no plumbing permit. The license requirement does not apply to plumbing by a person in a single-family residence that the person occupies or will occupy as a bona fide personal home, as long as the work meets the board’s laws and rules. A municipality may not require plumbers to hold a municipal license. This is 32 M.R.S. §§ 3302, 3301.
