Jackson County, MS Solar Energy: Panel Permits (2026)

Jackson County requires a combined building and electrical permit for residential rooftop solar photovoltaic installations, reviewed by the Planning and Zoning Department. Plans must include panel layout, structural calculations demonstrating roof capacity, electrical interconnection diagrams, and attachment hardware specifications. Due to Jackson County's location in the ASCE 7-16 Ultimate Wind Speed Zone of 150 to 160 mph (Risk Category II), hurricane-rated racking and structural attachments are required, typically using through-bolting to rafters rather than lag screws alone. Fire setbacks for firefighter access follow the International Residential Code Section R324: 18-inch pathway from roof ridge on single-ridge roofs, and 3-foot setback from roof edges on hip roofs. Ground-mounted systems must meet zoning setbacks (typically 10 feet from side and rear property lines) and may not exceed 15 feet in height. The Mississippi Public Service Commission authorized net metering in 2015, and Mississippi Power Company offers net metering for systems up to 20 kW residential. Coastal corrosion-resistant hardware (stainless or galvanized) is recommended due to salt air exposure. Post-installation inspections required before utility interconnection.
