To get a plumbing license in North Carolina, you must meet specific experience requirements and pass state-approved exams, all managed by the NC State Board of Examiners of Plumbing, Heating, and Fire Sprinkler Contractors. The state offers several distinct license classes, each with a different scope of work, from single-family homes to large industrial projects. This guide will walk you through every official requirement, fee, and step to secure your North Carolina plumbing contractor license.

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.

Step 3: Schedule and Pass the Required Exams

Once the Board approves your application, you will receive instructions for scheduling your exams with PSI, the state's approved third-party testing service. All applicants must pass two separate exams:

  1. Technical Exam: This covers trade-specific knowledge, codes, and practices relevant to your license classification.
  2. Business and Law Exam: This covers North Carolina-specific laws, regulations, and business practices for contractors.

Exam details, including content outlines and scheduling procedures, are available in the candidate information bulletin provided by the testing service.

Step 4: Submit Your License Activation Form

After successfully passing both exams, you must submit a license activation form and the required license fee to the Board within the timeframe the Board sets after you pass; confirm the current deadline when you pass your exams. Once your activation is processed and any final requirements are met, your license will be issued.
