New Hanover County Plumbing Permit Requirements
In New Hanover County, North Carolina, the Building Safety Department is responsible for enforcing the North Carolina State Building Code, which includes regulations for plumbing work. Permits are generally required for most construction, renovation, or system work that impacts a structure's safety or use. This includes new plumbing installations, extensions, replacements, or general repairs to any plumbing system. The county utilizes the Customer Online Access Services Tool (COAST) for permit applications, tracking, and online fee payments.
Jurisdiction and Unincorporated Areas
New Hanover County's Building Safety Department has jurisdiction over building and safety matters within the county. While the provided search results do not explicitly detail specific rules for unincorporated areas within New Hanover County, North Carolina state law generally requires permits for plumbing work in such areas, with the installer or responsible person being the one to secure the permit.
When a Permit May Not Be Required
Permits are typically not required for minor repairs or replacements of plumbing fixtures, provided these do not alter the original water supply, waste, or ventilation system. For one- or two-family dwellings, replacing a water heater may be exempt from permitting if the new unit's energy use rate or thermal input does not exceed the old one's, and there is no change in fuel, energy source, or location. However, even with exemptions, all work must comply with the North Carolina State Building Code.
Licensed Contractors and Homeowner Exemptions
North Carolina law generally requires plumbing work to be performed by a licensed contractor. However, there is a homeowner exemption that allows property owners to perform plumbing work on their primary, owner-occupied residence without a contractor's license. It is important to note that this exemption does not waive the requirement for obtaining a permit. Unpermitted work is a violation regardless of who performs it.
Key Requirements and Procedures
- Permits are required for new buildings, additions, and significant renovations, including interior structural or layout changes, full kitchen/bath remodels, and new or re-piped plumbing fixtures.
- Mechanical permits are required for any installation or change to heating and cooling systems.
- Rough-in plumbing inspections require all drainage, waste, and vent piping to be installed per code and tested.
- New Hanover County permits are generally valid for 6 months from the date of issuance and remain active with regular inspections. A lapse in work for over 12 months may require reapplication or extension.
- For inspections, requests are made through the New Hanover County COAST Development Portal.

North Carolina Plumbing Legislation, Codes, and Guidelines
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.
Primary Regulatory Agencies
- North Carolina Building Code Council (BCC): Operating under the North Carolina Department of Insurance, this body is responsible for the adoption, amendment, and maintenance of the North Carolina State Building Code, including the plumbing volume.
- North Carolina Office of State Fire Marshal (OSFM): The OSFM provides administrative support to the Building Code Council and oversees the engineering and codes staff responsible for interpreting and enforcing the state building codes.
- North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors (NCSBEPHFSC): While the BCC sets the technical code for construction, this board holds the primary authority for licensing plumbing contractors in the state under North Carolina General Statutes Chapter 87, Article 2.
