ADUs and JADUs - Town of Fairfax

An Accessory Dwelling Unit (aka, “second unit,” “in-law unit,” or “granny unit”) is an additional dwelling located on the same lot as a single-family or multi-family development. An Accessory Dwelling Unit may be attached to the primary residence, detached from the primary residence, or contained within an existing residence or accessory structure. A Junior Accessory Dwelling Unit (JADU) is a unit in an owner-occupied residence that is no more than 500 square feet and contained entirely within the single-family structure. The Town code was recently amended to allow ADUs in commercial zoning districts.
