route How to become a plumber in Tennessee
To become a licensed plumber in Tennessee, individuals can pursue either a Limited Licensed Plumber (LLP) license for projects under $25,000 or a CMC-A (Plumbing and Gas Piping Contractor) license for projects $25,000 or more, both issued by the Tennessee Board for Licensing Contractors. The LLP license requires at least one year of plumbing experience and passing the LLP exam, while the CMC-A requires three years of verifiable plumbing experience (or an engineering degree) and passing both the CMC-A trade exam and a Business and Law exam. While Tennessee offers trade exam waivers for the CMC-A license with several states, it's important to note that these are not full reciprocity agreements, and the Tennessee Business and Law exam is still required.

Financial statements and insurance are required for the CMC-A license. |
