A detached ADU is a small, separate home set a thoughtful distance from the main house. Siting usually comes down to driveway reach, septic location and tree cover.

A full kitchen, bedroom, bath and living area makes the unit feel like a home rather than a long-term guest room. Private entry away from the main driveway helps both households hold their own routines.
Heat for a detached unit is a real choice. A cold-climate heat pump often carries the load with electric backup.
The Efficiency Maine heat pump program is worth reviewing before mechanical scope is set.
