Building Codes in Maine

Building permit requirements in Maine are enforced at the local level, each city and county building department sets its own rules, fees, and timelines. Most cities in Maine follow the 2021 IRC.

We cover 12 cities in Maine with 1,263 specific permit rules. That's real, locally researched data, not generic advice. Each city page shows exactly what triggers a permit, what's exempt, estimated fees, and how to apply.

The bottom line: don't assume your city follows the same rules as the one next door. A fence that's exempt in one town might need a full permit two miles away. Always check your specific city.
