Are accessory dwelling units legal statewide in Minnesota?

No — Minnesota has no statewide ADU mandate as of 2026. ADUs are allowed at the discretion of each city; Minneapolis and Saint Paul are among the most permissive, with Saint Paul's 2023 ordinance allowing up to two ADUs per single-family lot.

How do I find zoning and parcel data for a Minnesota property outside the Twin Cities?

The Minnesota Geospatial Commons hosts a statewide compiled parcel dataset, but it depends on individual counties opting in, so coverage is not complete for every county. For a definitive zoning determination, confirm directly with the city or county planning department.

Minnesota zoning: how it works and what you can build

Minnesota pairs a standard municipal zoning enabling act with a unique layer of regional coordination in the seven-county Twin Cities metro, and Minneapolis's 2018 elimination of single-family-only zoning — after years of litigation — has made it one of the most closely watched zoning reforms in the country.

How zoning works in Minnesota

Minnesota municipalities zone under the Municipal Planning Act, codified at Minnesota Statutes Chapter 462, the general enabling statute for comprehensive plans, zoning ordinances, and subdivision regulation. Minnesota is not a strong home-rule state in the constitutional sense — cities exercise zoning power as delegated by Chapter 462 — but in practice local governing bodies have wide discretion within that statutory framework. The seven-county Twin Cities metropolitan area carries an additional layer unusual among Midwestern states: the Metropolitan Land Planning Act (Minnesota Statutes Chapter 473, dating to 1976) requires every local comprehensive plan in the metro to be reviewed by the Metropolitan Council for conformity with regional system plans for transportation, wastewater, and parks, meaning a Twin Cities zoning change can trigger regional as well as local review.

Minneapolis drew national attention as one of the first major U.S. cities to eliminate single-family-only zoning citywide, through its 2040 Comprehensive Plan adopted in 2018–2019, which allowed duplexes and triplexes on any residential lot. That reform was tied up for years by litigation: a 2022 injunction issued by a Hennepin County District Court under the Minnesota Environmental Rights Act halted implementation of the plan's residential provisions, but the Minnesota Court of Appeals ruled in May 2024 that the 2040 Plan is a policy document not subject to MERA legal challenges, reversing the injunction and allowing multifamily permitting to resume; the Minnesota Supreme Court denied a further petition for review that August. The 2024 Legislature separately passed a bill exempting already-adopted local comprehensive plans in the seven-county metro from that environmental-review requirement retroactively, reinforcing the 2040 Plan's legal footing. Saint Paul liberalized its own accessory dwelling unit rules in 2023 (Ordinance 23-43), allowing up to two ADUs per single-family lot.

Outside the Twin Cities, there is no statewide ADU or missing-middle mandate as of 2026 — proposals to take Minneapolis-style reforms statewide (eliminating parking minimums, allowing duplexes and fourplexes broadly) have circulated in the Legislature but had not been enacted as of this writing. For developers, that means zoning outcomes in Greater Minnesota remain governed purely by each city's own Chapter 462 ordinance, with no regional or state overlay to check beyond the metro area.

Who holds the zoning power

Land-use authority in Minnesota is delegated by statute, not assumed — these are the acts a zoning ordinance in Minnesota has to trace back to.

Minnesota Municipal Planning Act Minnesota Statutes Chapter 462: General enabling statute for municipal comprehensive plans, zoning ordinances, and subdivision regulation
Metropolitan Land Planning Act Minnesota Statutes Chapter 473, Sections 473.851–473.871: Requires Twin Cities metro local comprehensive plans to conform with Metropolitan Council regional system plans

Major cities and their codes

The enabling act sets the ceiling; the municipal code is what a project is actually reviewed against. The 7 largest Minnesota jurisdictions and the codes they administer:

Minnesota — municipal zoning codes
City	Zoning code
Minneapolis	Minneapolis Zoning Code, Title 20 of the Minneapolis Code of Ordinances Eliminated single-family-only zoning citywide under the 2040 Plan, after a multi-year injunction was lifted in 2024
Saint Paul	Saint Paul Zoning Code, Chapters 60–69 of the Saint Paul Legislative Code Expanded ADU allowances in 2023 (Ordinance 23-43) to up to two units per single-family lot
Rochester	City of Rochester Unified Development Code Mayo Clinic-driven Destination Medical Center district carries its own development standards
Duluth	City of Duluth Unified Development Chapter Steep topography and Lake Superior shoreland rules add overlay complexity to base zoning
Bloomington	City of Bloomington Zoning Ordinance Mall of America area zoning drives significant mixed-use and hospitality development
Brooklyn Park	City of Brooklyn Park Zoning Ordinance One of the metro's larger suburbs with substantial remaining greenfield and infill capacity
Plymouth	City of Plymouth Zoning Ordinance Western-suburb zoning oriented around planned-unit-development standards

Recent reforms

State-level changes override or preempt what a local ordinance says — these are the Minnesota reforms that move the numbers on a real site.

2024 Legislature exempts metro comp plans from MERA review Retroactively exempted Twin Cities comprehensive plans from the environmental review that had stalled the 2040 Plan
2024 Court of Appeals reverses 2040 Plan injunction Minnesota Court of Appeals ruled the 2040 Plan is a policy document not subject to MERA challenges, reversing the district court injunction; the Minnesota Supreme Court denied further review that August
2023 Saint Paul Ordinance 23-43 Allowed up to two accessory dwelling units per single-family lot and eased ADU size limits
2018 Minneapolis 2040 Plan Eliminated single-family-only zoning citywide, allowing duplexes and triplexes on any residential lot

Parcel & GIS data

The Minnesota Geospatial Commons (gisdata.mn.gov), maintained by the Minnesota Geospatial Information Office (MnGeo), hosts a compiled statewide parcel layer sourced from opt-in county data — currently covering a majority but not all of Minnesota's 87 counties.

Real parcel geometry is already loaded for Bloomington — see the zoning-by-city section above for a live district-and-parcel lookup there. That is not the same as a cited feasibility report: Chicago is still the only jurisdiction with bulk standards, § citations and a generated massing scheme.

Zoning by city

The statute sets who may zone; the city's own code sets what you can build. One guide per Minnesota city below, explaining the district codes that appear on its zoning map — 109 district codes across Minnesota so far.

Minnesota zoning — common questions

Did Minneapolis really ban single-family-only zoning?: Yes. Minneapolis's 2018–2019 2040 Plan allowed duplexes and triplexes on any residential lot citywide. A 2022 lawsuit under the Minnesota Environmental Rights Act won an injunction blocking the residential provisions, but the Minnesota Court of Appeals ruled in May 2024 that the 2040 Plan is a policy document not subject to MERA challenges, reversing the injunction, and the Minnesota Supreme Court denied further review that August. The Legislature separately exempted metro comprehensive plans from that review requirement in 2024, so the reform now stands.
Are accessory dwelling units legal statewide in Minnesota?: No — Minnesota has no statewide ADU mandate as of 2026. ADUs are allowed at the discretion of each city; Minneapolis and Saint Paul are among the most permissive, with Saint Paul's 2023 ordinance allowing up to two ADUs per single-family lot.
Does the Twin Cities metro area have regional zoning coordination?: Yes. Under the Metropolitan Land Planning Act (Chapter 473), the seven-county metro's local comprehensive plans must be reviewed by the Metropolitan Council for conformity with regional system plans for transportation and infrastructure, a layer that sits on top of each city's own zoning ordinance under Chapter 462.
How do I find zoning and parcel data for a Minnesota property outside the Twin Cities?: The Minnesota Geospatial Commons hosts a statewide compiled parcel dataset, but it depends on individual counties opting in, so coverage is not complete for every county. For a definitive zoning determination, confirm directly with the city or county planning department.
