Follow these steps to obtain your North Carolina plumbing contractor license.
Step 1: Meet Experience Criteria
First, ensure you have the required hours of documented hands-on experience for your desired license class. Gather proof of your work history, such as letters from employers, and any transcripts from relevant academic or technical training programs.

Once your activation is processed and any final requirements are met, your license will be issued.
North Carolina Plumbing License Renewal and Continuing Education
All North Carolina plumbing contractor licenses must be renewed annually to remain active.
Renewal Cycle and Deadlines
North Carolina plumbing contractor licenses expire on December 31 of each year. The Board sends out renewal notices, and licenses must be renewed by January 31 to avoid a late fee. The annual renewal fee is $150.
Continuing Education (CE) Requirements
Continuing education requirements are not stated in the Board's cited application or renewal forms. Confirm any current CE requirements directly with the Board before your renewal period.
North Carolina Plumbing License Reciprocity and Endorsement
North Carolina does not offer general reciprocity for plumbing licenses with any other state. However, the state does have a specific technical exam waiver agreement with South Carolina.

Even with a technical exam waiver, all applicants must still pass the North Carolina Business and Law exam to be eligible for licensure.
