In 1995, Evelyn Brown purchased her property in Seattle, WA and immediately imagined building a second house on it. The property was a through-lot, meaning that it spanned the distance between two streets. Her house, at one end of the property, fronted on one street and her garage, on the other end of the property, fronted the other street. Twenty years later the city caught up with Evelyn’s vision and she now lives in an ADU she has plenty of time to dream about.
