What is an accessory dwelling unit?<\/h2>\n

An accessory dwelling unit<\/a> is a secondary residential unit located on the same lot as a primary home. It has its own living space and typically includes a kitchen, bathroom, and sleeping area. Many ADUs range in size from about 600 to 1,200 square feet<\/a>.<\/p>\n

Denise Madan<\/a>, a HomeLight Elite agent in Florida with 27 years of experience, explains that an ADU can be known by many names. \u201cWe call it an in-law quarter, next-generation quarter, or efficiency studio.\u201d<\/p>\n

Other names for ADUs include granny flats, backyard cottages, casitas, garage apartments, carriage houses, and ohana units<\/a>.<\/p>\n
