North Carolina Plumbing Exam Information

North Carolina has adopted the International Plumbing Code (IPC), the International Fuel Gas Code (IFGC), the International Administrative Code (IAC) and the International Residential Code (IRC). When studying for your plumbing exam, you'll need to be sure to get the correct version of the International codes as NC has added its own amendments. Be sure you have the 2018 NC Plumbing Code, the 2018 NC Fuel Gas Code, the 2018 NC Administrative Code, and the 2018 NC Residential Code. These are based on the 2015 International Codes.


North Carolina offers plumbing licenses under three(3) classifications:

  • NC Plumbing Contractor - Class 1 (Residential and Commercial Plumbing)
  • NC Plumbing Contractor - Class 2 (Residential Plumbing Only)
  • NC Plumbing Technician (sub-licensee of a licensed plumbing contractor)

North Carolina does not have reciprocity for these licenses with any other state. Anyone seeking a NC plumbing license must pass a NC exam even if they are licensed by another state.
