Do you need a permit for Pool Construction in Knox County?

Any pool more than 24 inches deep requires a permit and a compliant safety barrier at least 48 inches high with self-closing, self-latching gates (IRC R326 / ISPSC). Prefabricated pools under 24 inches deep are exempt. Plans are reviewed under the Statewide code (IRC 2018); apply through Knox County Ohio Regional Planning before work begins.
