North Carolina Plumbing Code and Legislation

Plumbing standards in North Carolina are governed by the North Carolina State Building Code, which is adopted and amended by the North Carolina Building Code Council (BCC). The state's plumbing requirements are derived from the International Plumbing Code (IPC), published by the International Code Council (ICC), but are not applied verbatim. Instead, the BCC incorporates state-specific amendments to create the North Carolina Plumbing Code.

As of early 2026, the state has been in the process of transitioning to the 2024 North Carolina Plumbing Code, which is based on the 2021 edition of the International Plumbing Code. Implementation of these updated codes has been subject to legislative delays, and users should verify the currently enforced edition with their local building inspections department.
