Project Goals And Site Review

Frequently Asked Questions

What is an accessory dwelling unit (ADU)?

An accessory dwelling unit, or ADU, is a secondary living space located on the same property as a primary home. It may be detached, attached, converted from a garage, or created within an existing structure. Homeowners often build ADUs for family housing, guest suites, rental flexibility, home offices, or added property value.
