From the massive commercial developments in downtown Atlanta to the expanding residential suburbs of Augusta, Georgia's infrastructure is growing rapidly. Clean water delivery and safe sanitation are vital to this growth. Because poor plumbing can lead to catastrophic property damage and health crises, the state strictly regulates who can alter or install water and gas piping.
Whether you are pulling a permit for a massive commercial boiler or roughing-in a new custom home, you must carry a valid credential. The state offers three distinct pathways for Plumbing professionals, each requiring verified hours and passing scores on difficult code exams.

- Journeyman Plumber: Allows you to install, maintain, and repair plumbing systems, but you must work under the direction of a licensed Master Plumber. You cannot pull permits or run your own contracting business.
- Master Plumber (Class I): Restricted. Allows you to run a business and pull permits, but you are limited to single-family homes or commercial buildings that do not exceed one story in height.
- Master Plumber (Class II): Unrestricted. The highest level. You can bid on and execute plumbing contracts for any building, including hospitals and skyscrapers.
2. Experience & Exam Requirements
To upgrade from an apprentice to a licensed professional, the Georgia Board demands strict documentation of your hours.
- For Journeyman: You must document at least 3 years of primary experience under a Master Plumber.
- For Master (Class I & II): You need 5 years of total experience. For Class II, part of that experience must specifically involve commercial or industrial plumbing systems.
- The Exam: All tiers must pass a state exam administered by PSI. Master Plumbers must also pass questions related to Georgia business and law regulations. The test focuses heavily on the International Plumbing Code (IPC).
