Oregon just staked its claim as the state that’s most aggressively trying to address affordable housing.
The Beaver State passed what’s effectively a state-wide ban on single-family zoning on Sunday, the last day of a dramatic legislative session that saw Oregon Senate Republicans flee the state to avoid a vote on a cap-and-trade climate bill.

The bill doesn’t directly ban single-family zoning, which limits a residential plot to only single-family detached houses. It legalizes duplexes in cities of more than 10,000, including the Portland metro area. In cities of more than 25,000 and within the Portland metro area, it would legalize triplexes, fourplexes, attached townhomes, and some “cottage clusters.” The bill leaves few towns in the state where single-family zoning is still operable.
