Oregon Becomes First State to Ditch Single-Family Zoning

"On Sunday, the Oregon Senate passed HB 2001 by a 17-9 vote, with Republicans and Democrats lining up on both sides of the bill. The Oregon House approved its version of the bill two weeks ago in a similarly bipartisan 43-16 vote.

HB 2001 legalizes the development of duplexes on residential land currently zoned for single-family housing in all communities with a population of 10,000 or more. The bill also allows for the construction of "missing middle" housing—a term which refers to three- and four-unit homes—on single-family-zoned land in cities of 25,000 or more.

The bill is intended to arrest mounting rents and home prices by easing restrictions on the supply of new housing."
