Do I need a permit for retaining wall construction in Jackson?
It depends. Whether retaining wall construction needs a permit in Jackson comes down to the details of your project.
No statewide retaining wall height exemption was verified; the model code 4 foot figure applies only where the local jurisdiction adopted it (Miss. Code 17-2-4). Mississippi law requires every county, for its unincorporated areas, and every municipality to require permitting as a condition to construction whether or not it has adopted building codes (Miss. Code 19-5-9(11) and 21-19-25(6), added by HB 1163 in 2022). Residential building codes are local option in Mississippi: a county or city could opt out of the State Uniform Construction Code, so plan review and inspections depend on which office has the address (Miss. Code 17-2-4).
Local detail for Jackson: Jackson does not publish a direct phone number for its Building Permit Office. Apply through the city's online permit portal, or call the city's 311 line at 601-960-1111 to be routed.
