"On Sunday, Oregon lawmakers gave their final approval to House Bill 2001, which would eliminate single-family zoning around the state. In cities with more than 25,000 residents, duplexes, triplexes, fourplexes, and “cottage clusters” would be allowed on parcels that are currently reserved for single-family houses; in cities of least 10,000, duplexes would be allowed in single-family zones."
