Contractor License in Maine

Local / no state license

Maine currently does not license general contractors at the state level, and most municipalities require little or no licensing. The state licenses specific trades (electricians, plumbers, oil/propane technicians) through OPOR. Note: a new Maine Home Contractor Licensing Act takes effect January 1, 2027, adding a state license for residential projects over $15,000.

How to get licensed in Maine

  1. Confirm whether the municipality where you will work has any local registration requirement (many do not).
  2. For any home construction contract over $3,000, use a written contract meeting Title 10 requirements (warranty, deposit cap of one-third, start/finish dates, written change orders).
  3. If performing a licensed trade (electrical, plumbing, fuel), apply for that license through OPOR and pass the required exam.
  4. Maintain appropriate general liability and workers' compensation insurance as a business best practice.
  5. Prepare for the Maine Home Contractor Licensing Act taking effect January 1, 2027, which will require a state license for residential projects over $15,000.
