Maple Grove, MN Building Setbacks & Zoning: Lot Coverage Limits (2026)

Maple Grove controls lot coverage primarily through an impervious-surface limit. Sec. 36-787 of the Zoning Ordinance provides that "for each lot in the R-1, R-2, and R-3 zoning districts, the maximum area of impervious surface shall be 40 percent," with an exception allowing up to 75 percent for certain religious, school, and public recreational uses. Impervious surface includes the house, garage, driveway, patios, sheds, and other hard surfaces that prevent infiltration, so this 40 percent figure effectively caps how much of a typical residential lot can be built or paved over. A separate accessory-building coverage rule limits bulk: per the city's Sheds and Garages handouts, "the total area of the garage and all accessory buildings on a lot cannot exceed 1,254 square feet," no single garage or accessory building may exceed 1,000 square feet, and a maximum of two detached accessory buildings are allowed per lot (if two are built, one must be no larger than 200 square feet). Minimum lot sizes that frame coverage also vary by district; Sec. 36-783 lists standards for lots of record, such as 20,000 square feet and 100 feet wide in R-1, and larger minimums in R-A. Because compliance is verified by survey, building and deck permit applications must include a certificate of survey demonstrating lot coverage along with setbacks and easement clearances.
