Brunswick County, NC Plumbing Permit Requirements

Brunswick County, North Carolina, through its Code Administration department, handles the issuance of building permits, including those for plumbing work. The county has jurisdiction over building and safety matters, including for properties in unincorporated areas.

A plumbing permit is required for the installation, extension, relocation, replacement, or general repair of any plumbing system. However, minor repairs or replacements of plumbing fixtures that do not disrupt the original water supply, waste, or ventilation system do not require a permit. Homeowners may perform their own plumbing work if they own the land and will personally occupy the structure.

For projects where the construction cost exceeds $40,000, a general contractor licensed in North Carolina is required. Homeowners can act as their own general contractor for the construction of a home, addition, or accessory structure if they own the land and will personally occupy the structure for 12 months after completion. Licensed contractors are responsible for knowing and following North Carolina building codes.

All building permits, including plumbing permits, are generally submitted online through the Brunswick County Permit Portal. For assistance with the application process, individuals can utilize lobby computers at the county offices, where a permitting technician can provide support.

Unincorporated Areas

The rules for properties in unincorporated areas of Brunswick County are the same as for other areas within the county's jurisdiction. The Code Administration department oversees building and safety for all areas within Brunswick County, including unincorporated regions.

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.
