What Is an ADU Home Addition?

An ADU home addition is a secondary living unit attached to your primary residence. Unlike detached ADUs, these additions:✔ Share a wall with your main home✔ Maximize yard space by building vertically or horizontally✔ Offer easier utility connections (shared plumbing/electrical)✔ Can be converted from existing space (garage, basement, or new construction)

For Riverside’s specific ADU regulations, visit the City of Riverside’s Planning Department.
