No. Maine doesn't license carpenters as a trade. There is no state contractor license or registration, though cities may have their own rules.
No state requirement · By ChiselJobs Team · Updated
In short
Maine does not license carpenters or contractors at the state level, and there is no general, residential or home improvement contractor license. What the state does require is a written contract for home construction work over $3,000, under the Home Construction Contracts Act, which falls under the Maine Attorney General. There is no exam or experience requirement. Cities and towns may set their own rules, so check with the local code office before starting a job. Building work follows the 2021 IRC and IBC with state amendments. The Maine Department of Labor runs the state apprenticeship program for anyone entering the trade.
