New York just made it legal to build a small home in your backyard. Hundreds of thousands of homeowners are now sitting on hidden housing. An ADU is an Ancillary Dwelling Unit, a small, independent home on the same lot as a house. A backyard cottage. A converted garage. Its own kitchen, bath, and door.
