Frequently Asked Questions

What qualifies as an accessory dwelling unit?

An accessory dwelling unit, or ADU, is a secondary residential living space on the same property as a primary home. It may be detached, attached, converted from a garage, or created within an existing structure. A qualifying ADU typically includes independent living functions such as sleeping, cooking, and bathing areas and must meet applicable local zoning, building, and safety requirements.
