Jackson, MS Building Setbacks & Zoning: Lot Coverage Limits (2026)

03(7) of the Jackson Zoning Ordinance sets the R-1 Single-Family Residential District's maximum lot coverage at 'fifty percent (50%) including accessory structures,' meaning the house, garage, sheds, and any other roofed structure on an R-1 lot cannot together occupy more than half the parcel. 4(7) sets the identical 'fifteen (15) percent' cap for the SR Suburban Rural Residential District, which requires three-acre or 130,680-square-foot minimum lots. Each of these coverage figures sits inside the numbered 'Regulations' list for its own district in Article VI, alongside that district's minimum lot area, lot width, yard depths, and maximum building height, so a property owner has to read the specific district section, not a citywide table, to find the governing percentage.

Coverage is measured to include accessory structures such as detached garages and storage buildings, not just the primary dwelling; the R-1 section explicitly folds accessory structures into the 50 percent figure, and the R-1E and SR sections do the same for their 15 percent caps. Compliance is checked by the Zoning Administrator at the building permit stage before construction begins. A property owner who wants to exceed the district's coverage limit has no administrative override in these sections; relief would require pursuing a variance through the Board of Adjustment procedures described elsewhere in the Ordinance.
