Minneapolis Ended Single-Family-Only Zoning — and the Courts Upheld It

First in the nation, upheld

Minneapolis made national news in December 2018 when it became the first major U.S. city to eliminate single-family-only zoning through its 2040 Comprehensive Plan. After a multi-year legal challenge, that landmark policy was ultimately allowed to stand — a resolution with real consequences for how the city's neighborhoods can grow.

The decision to end single-family-only zoning, and the courts' eventual clearing of the legal path for it, reshaped the rules that govern construction across Minneapolis, including the lakes-and-hill neighborhoods.

What 'ending single-family zoning' actually meant

Before 2040, large swaths of Minneapolis were zoned to allow only detached single-family homes — one house per lot, by law. The 2040 Plan changed that by allowing up to three units, meaning duplexes and triplexes, on residential lots citywide. It opened more of the city to modest 'missing middle' housing, the small multi-unit buildings that sit between single houses and large apartment blocks.

Crucially, it was a change to what is permitted, not a requirement to redevelop anything. A single-family home remains entirely legal and always will be; the difference is that a duplex or triplex is now an option in places it previously was forbidden. Nobody is forced to build, sell or change a thing.

It was a change to what's permitted, not a requirement to build. A single-family home is still legal — a duplex is simply now an option too.

How the courts cleared it

The path was not smooth. Opponents sued under the Minnesota Environmental Rights Act, and a Hennepin County district court halted the plan, finding the environmental challenge could proceed and ordering the city to stop implementing it. For a stretch, the landmark policy was suspended.

But the Minnesota Court of Appeals reversed that injunction on May 13, 2024, allowing enforcement to resume. The 2024 Legislature then codified a residential-density exemption from MERA, and the Minnesota Supreme Court declined to take the environmental challenge further — a sequence that, taken together, left the policy intact and largely shielded from the same kind of suit.

What it means for the neighborhoods

For the Wedge, Lowry Hill, East Isles and the lakes areas, the upheld policy means small-scale density — a duplex where a single house once stood, a triplex on a corner lot — is now a permanent part of the zoning landscape rather than a contested experiment.
