Johnston County issues no building permits; the state’s building code commission lists the county as not issuing them. What the county does run is a floodplain program: the Board of County Commissioners adopted floodplain ordinances on July 25, 2011, and Johnston County Emergency Management in Tishomingo (580-371-0174) handles the floodplain permit application. Tishomingo and Ravia are the only towns not listed as non-issuing, and Ravia sells a $40 building permit at its Town Hall.
