ADU Rules in Minneapolis, Minnesota

Minneapolis is the Hennepin County seat and Minnesota's largest city, with a population of about 430,000. The larger of the Twin Cities (paired with Saint Paul, Minnesota's capital), Minneapolis is a national leader on housing policy. Minneapolis 2040 (adopted 2018, effective 2020) eliminated single-family-only zoning citywide — a landmark reform allowing duplexes, triplexes, and ADUs throughout residential neighborhoods. Minnesota also enacted statewide ADU legislation in 2024. Minneapolis and Saint Paul are entirely separate cities.

Minneapolis 2040 — Landmark Zoning Reform

Minneapolis 2040 was a landmark reform that:

• Eliminated single-family-only zoning throughout the city
• Allowed duplexes and triplexes throughout residential areas
• Broadly allowed ADUs on residential properties citywide
• Reduced parking minimums

This makes Minneapolis one of the most permissive cities in the US for ADUs. Verify current specific ADU standards with Minneapolis Development Services.

Minnesota Statewide ADU Law (2024)

Minnesota's 2024 Housing Solutions Act requires cities statewide to allow ADUs by right. Minneapolis's existing policies already exceed state minimums — verify current implementation.

Mississippi River Critical Area

Minneapolis sits on the Mississippi River. The Mississippi River Critical Area designation applies to properties near the river — additional review required for development near the riverbanks. The Minneapolis Park Board manages the River Road parkway.

Minnesota Shoreland Management Act

Properties near the Mississippi River or other public waters may be subject to Minnesota's Shoreland Management Act (development within 1,000 feet of classified water bodies). Verify shoreland status for waterfront properties.
