Do You Need a Contractor License in Maine?

Contractor License in Maine

Local / no state license

The short version

Maine has no single statewide general contractor license. Licensing and registration are handled at the county or city level, so what you need depends on where the job is. The Maine Office of Professional and Occupational Regulation is the state agency to start with, then check with the local building department.

Getting licensed in Maine: the usual steps

Confirm which classification you need (general, residential, or a specific trade).
Check experience and exam requirements with the Maine Office of Professional and Occupational Regulation.
Carry the required general liability and, where required, workers comp insurance.
Register your business entity and secure any bond the state asks for.
Apply, pass any required exam, and keep the license renewed on schedule.

Insurance and a certificate of insurance (COI) are almost always part of it. You can track your own and your subs' COI dates with the free Krewbase COI tracker.
