How to Become a New York City Licensed MASTER PLUMBER

Where the required level of experience requires supervision from a licensed Master Plumber, the application must include documentation that proves you have the required work/educational experience under the direct supervision of a licensed Master Plumber in the jurisdiction within which you obtained your experience. The Department of Buildings requires payroll records, notarized or sealed letters from employers that detail the type of work performed, and any other documents the Department requests.
