Oregon residential & ADU permit data
First state to end single-family-only zoning
Housing law
Oregon allows accessory dwelling units by-right in single-family zones within urban growth boundaries, with no owner-occupancy requirement and no extra off-street parking mandate.
HB 2001 (2019) legalized middle housing statewide — duplexes in mid-size cities and up to fourplexes, cottage clusters and townhouses in large cities and the Portland metro.
