Does Indiana use the IPC or the UPC for plumbing?
Answered by AskBaily Editorial · Updated
Short answer
Indiana uniquely adopts the Uniform Plumbing Code (UPC) as its statewide plumbing standard under 675 IAC 16. Surrounding states (Ohio, Michigan, Illinois, Kentucky) adopt the International Plumbing Code (IPC). The UPC / IPC divide affects fixture-count calculations, venting geometry, and drain-waste-vent layout. Indianapolis residential plumbing permits require a licensed plumber of record holding an IN PLA credential.
