"By right" means your ADU is approved administratively — you submit plans, meet dimensional standards, and receive a building permit without a public hearing. "By special permit" requires a planning board hearing where neighbors can comment, and approval may include conditions. Maine’s LD 2003 (2022) established ADU by-right statewide in residential zones, simplifying the process for most homeowners.
