Jackson County, MS Accessory Structures: Shed Rules (2026)

Jackson County controls sheds and outbuildings through municipal building and zoning ordinances in Pascagoula, Ocean Springs, Moss Point, Gautier, and Vancleave, with unincorporated areas under county jurisdiction. Small sheds under 120 to 200 square feet and single-story construction typically do not require a building permit under adopted International Residential Code exemptions, though zoning setbacks still apply. Larger structures require building permits, engineered plans if over certain sizes, and must meet the Mississippi Gulf Coast Building Code wind load requirements (adopted post-Katrina to handle hurricane winds). Standard setbacks are 3 to 5 feet from side and rear property lines, with larger setbacks often required from street frontage. Maximum lot coverage limits (typically 30 to 40 percent including primary dwelling and accessory structures) may restrict total accessory structure area. Sheds cannot be used for habitation, commercial activity, or permanent storage of hazardous materials. Metal, wood, vinyl, and prefabricated structures are generally permitted. Mississippi's humid subtropical climate and pervasive termite activity (Formosan subterranean termites are present on the Gulf Coast) make proper concrete or treated wood foundations and ventilation important for longevity. Structures in flood zones (large portions of coastal Jackson County are in AE, VE, or X zones) must comply with local floodplain management regulations, often requiring elevation above base flood elevation or flood vents. Hurricane tie-downs or anchoring systems are recommended for sheds in high-wind exposure areas.
