Jackson County, MS Building Setbacks & Zoning: Setback Rules (2026)

Jackson County's dimensional standards for the R-1 Single-Family Residential District, published as Table 5-3.4 in the Zoning Ordinance, set a 35-foot front yard setback (also 35 feet for an accessory building in that front yard), a 10-foot interior side setback on each side, a 15-foot side setback where a corner lot abuts a second street right-of-way, and a 25-foot rear setback measured from the rear main building line. Accessory structures get a shorter minimum: not less than 5 feet from a rear lot line or 10 feet from a side lot line.

Section 4.02.03 fixes how that front setback is measured: the minimum horizontal distance is taken between the property line and the main structure. Section 4.02.02 covers corner and double-frontage ("through") lots: the front yard is the one facing the building's main entrance, the yard on the other street frontage counts as a side yard set at two-thirds of the required front setback under the general rule, and the yard opposite the main entrance is treated as the rear yard.

These are minimums, not targets: § 4.02.01 bars reducing any existing lot's yards below what the ordinance requires, and new lots must meet the minimums from the start. Every other residential and commercial district, R-1A through I-3, carries its own dimensional table with different setback figures, so a lot's zoning classification has to be confirmed with the Planning Department before design work begins.
