Minneapolis ends single-family zoning (2018)
Minneapolis became the first major U.S. city to eliminate single-family zoning, allowing up to three units on any residential lot. The change came through a 12-0 council vote as part of a plan to address a housing shortage and racial segregation.
The policy took effect in 2019, with duplexes and triplexes allowed citywide. Opposition and legal challenges followed, but the change stuck.
The reform became a national template for upzoning, and several states and cities later copied or adapted it.
Minneapolis removed the legal barrier Baltimore keeps: a case-by-case council vote for each conversion. By-right zoning avoids the cost and uncertainty of Baltimore's conditional-use path.
