What is an ADU? Although many people have never heard the term, accessory dwelling units are timeless and may be associated with  different names: granny flat, granny pod, secondary dwelling, or in-law apartment To be clear: An accessory Dwelling Unit (ADU) is a small residence that shares a residential lot with a larger, primary dwelling. As an independent living space, an ADU is self-contained, with its own kitchen, bathroom and sleeping area. An ADU can be attached or separate from a primary residence, including basement apartments and garage conversions.  

Since ADUs make use of the existing infrastructure and housing stock, they are also environmentally friendly and respectful of a neighborhood’s pace and style.
