Lansing, MI Building Setbacks & Zoning: Lot Coverage Limits (2026)

03, which governs the R-1 Residential District, the base single-family zone covering much of Lansing, Ingham County. Under the 'BUILDING MASSING' and 'BUILDING PLACEMENT' rows of that table, total impervious surfaces on an R-1 lot, meaning roofs, driveways, patios, walkways, and any other hard surface, cannot exceed 60 percent of the lot area, and the building footprint itself is separately capped at 45 percent. The same table sets the R-1 minimum lot size at 5,000 square feet, with a lot width between 50 and 200 feet and a minimum lot depth of 100 feet, so the coverage percentages apply against those lot dimensions.

03 also requires a 20-foot front setback (or the average setback on the block face), a 5-foot minimum side setback with 15 feet total for both sides, and a 30-foot rear setback, so impervious surface still has to fit inside that buildable area. 03 and cannot be enlarged in a way that increases the nonconformity. Property owners who need relief, for example to pave an oversized driveway or add a sunroom that would push coverage past the cap, must seek a dimensional variance from the Board of Zoning Appeals under Chapter 1274, which requires showing a practical difficulty or unnecessary hardship tied to the shape or physical condition of the specific lot.
