An ADU Defined
An accessory dwelling unit, or ADU, is a second, smaller home on the same lot as a main house. It has its own space to live, sleep, cook, and bathe.
Homeowners build ADUs for aging parents, adult children, guests, a home office, or rental income.
Common Types of ADUs
A detached ADU stands on its own in the yard. An attached ADU shares a wall with the house. A garage ADU is built above or within an existing or new garage. Some homeowners convert a basement into a separate unit.
What to Check Before You Build
Size, height, setbacks, and parking rules depend on your zoning. Confirm the requirements for your address with the City of Boise or your local city early, before design is settled. Utility connections and access to the site matter too.
Making It Look Like It Belongs
An ADU should complement the main house. John matches roof pitch, siding exposure, window trim, and colors outside, and finishes the interior with the same care he gives any home.
Common Questions
What is an ADU?
An accessory dwelling unit is a second, smaller home on the same lot as a main house. It can be detached, attached, or built over a garage, and it has its own living, sleeping, kitchen, and bathroom space.
Can I build an ADU on my Boise property?
Many Boise lots allow one, but size, height, setbacks, and parking depend on your zoning. Confirm the rules for your address with the City of Boise or your local city early. John helps you plan the design and the building process around those rules.
