Oregon close to becoming first U.S. state to ban single-family-only zoning

Earlier this month, Oregon’s legislature passed House Bill 2001, a measure that will require cities of more than 10,000 people to permit duplexes in areas currently zoned for single-family usage. The bill, which received bipartisan support, is set to go before Gov. Kate Brown, D-OR, who is expected to sign it, therefore positioning Oregon as the first state to ban single-family-only zoning. If passed, Redfin claims the measure could have a significant impact on Portland’s housing market.
