About Maine ADU Guide

This site was created as a resource for homeowners across Maine. Whether you live in a small town, city, or unincorporated area, you’ll find tailored information to help you successfully plan, design, permit, and build an Accessory Dwelling Unit.

Throughout this website, when you see “your City” or “the City” this also refers to the local governments for towns and unincorporated parts of the county. If you live outside city lines, you will follow the County’s standards.
