Recently, the state of Oregon has moved to use the power of policy to influence housing affordability, diversity and flexibility. In what some are calling an effective ban on single-family zoning, the state is requiring that multifamily units be allowed on land previously reserved just for single-family homes.
Oregon H.B. 2001, effective Aug. 8, 2019, mandates that each city with a population greater than or equal to 25,000 allow all middle housing types, and/or a duplex, on each lot or parcel that previously allowed for the development of detached single-family dwellings. This language has led to many sensationalized headlines labeling the move as a ban or elimination of single-family zoning.
