Heidi Rose’s ADU: A Home for My Sister

Heidi Rose first learned about ADUs because she was determined to figure out how she could build a home for her sister. Her twin sister was living in Seattle with her two kids and going through a divorce, so Heidi went to the City of Portland’s permitting office to explore alternative housing options. Heidi discovered that in the city of Portland an accessory dwelling unit up to 800 square feet is allowed by right on a single-family lot in most neighborhoods.
