ADU rules in Maple Grove, MN — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Maple Grove's zoning code (Chapter 36) does not contain a dedicated accessory dwelling unit ordinance. Minnesota has no statewide ADU mandate, so a second independent living unit on a single-family lot is not a use the city's accessory-building rules authorize. Confirm options directly with Community & Economic Development.
Unlike St. Paul, Minneapolis, Edina and Golden Valley, the City of Maple Grove has not adopted a standalone accessory dwelling unit (ADU) ordinance in its zoning code, Chapter 36. The city's residential accessory-building regulations (covered in the Residential Garages/Sheds handout and Chapter 36, Article VIII) address detached garages and sheds by size, height and setback, but classify them as accessory buildings, not as separate dwelling units. Minnesota does not impose a statewide law requiring cities to permit ADUs; the Minnesota Legislature leaves the decision to each municipality, which is why ADU rules vary widely across the metro. Because Maple Grove's code does not list an accessory or second dwelling unit as a permitted accessory use in its single-family districts (R-1, R-2), a homeowner cannot assume a backyard cottage, basement apartment with a separate entrance, or garage apartment is allowed by right. Anyone considering an ADU should contact the Community & Economic Development Department at 763-494-6040 to ask about variances, conditional uses, or any recent zoning amendments before designing or building.
Building or renting a second independent living unit that is not a permitted use can trigger a zoning enforcement action, a stop-work order, and a requirement to remove the unauthorized unit or living facilities; building permits are also required for the underlying construction.
