Maine permits
Do you need a permit in Maine?
Maine uses the Maine Uniform Building and Energy Code (MUBEC) in municipalities over 4,000 population; smaller towns may opt out, so rural permitting varies widely. Electrical and plumbing are state-licensed. Coastal shoreland zoning adds review near water.

Can a homeowner pull the permit?
Yes, in most cases. Owner-occupied primary residences. Licensed trades generally required for plumbing/electrical on covered work.
Where to file: Municipal code office where MUBEC applies; smaller towns may have minimal permitting. Portland has a portal. Plan review 1-3 weeks.
