ADU Rules
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.

Detached sheds are accessory buildings. They cannot exceed 15 feet in height, must sit at least 5 feet from all lot lines, and cannot be in a front or side yard. In R-1, R-2 and R-3 districts the total per-lot accessory area is 1,254 sq ft, with no single detached structure over 1,000 sq ft. Most sheds need a permit.

Some RestrictionsGarage Conversions
New single-family homes must include a garage with capacity for at least two cars, no smaller than 20 feet wide by 24 feet deep. Attached garages count against the lot's accessory-building total (1,254 sq ft in R-1/R-2/R-3, with a 1,000 sq ft per-structure cap), which constrains converting required garage space to living area.

Some RestrictionsCarport Rules
Maple Grove's code does not single out carports with a separate standard; a roofed carport is treated as an accessory structure subject to the general accessory-building rules: 15-foot height limit, 5-foot setback from lot lines, no placement in a front or side yard, and the district accessory-area caps. New homes must still have an enclosed two-car garage.

Some RestrictionsTiny Homes
Maple Grove's zoning code has no tiny-home or ADU category, so a tiny house used as a separate dwelling is not an authorized accessory use on a single-family lot. A site-built tiny home must meet the Minnesota State Building Code and minimum-dwelling standards; movable tiny houses on trailers are not permitted as permanent residences.
