How do you get a Tennessee plumber license (TN Board for Licensing Contractors)?
The Limited Licensed Plumber is the Tennessee feature worth understanding: it authorises plumbing work below a statutory project value, giving a route into independent work short of the full contractor licence, while projects above the threshold require the contractor licence with its financial statement and monetary limit. Tennessee's larger cities apply their own permitting and, in some cases, local plumber registration on top. The route therefore runs through experience at trade level followed by the TN Board for Licensing Contractors examination and the business requirements — insurance, and in most cases a bond and a financial showing — rather than through a state journeyman card. Hours, fees, examination content and renewal requirements are set by the Tennessee Board for Licensing Contractors, Department of Commerce and Insurance and revised periodically, so verify the current requirements with the TN Board for Licensing Contractors before you apply.
- Build supervised experience at trade level under a licensed plumber or contractor.
- Check whether the county or city you work in issues a journeyman card, and obtain it if so.
- Apply to the TN Board for Licensing Contractors for the plumbing classification and meet its qualifying requirements.
- Pass the trade and business examinations the board requires.
- File insurance and any bond or financial statement, then renew on the board's cycle.
Governing law: Tennessee Contractors Licensing Act of 1994 (Tennessee Code Annotated, Title 62, Chapter 6)

Tennessee plumber license types: the full TN Board for Licensing Contractors ladder
Tennessee does not run the apprentice-journeyman-master ladder at state level, so the tiers below describe what actually exists here rather than the generic national picture. The Limited Licensed Plumber is the Tennessee feature worth understanding: it authorises plumbing work below a statutory project value, giving a route into independent work short of the full contractor licence, while projects above the threshold require the contractor licence with its financial statement and monetary limit. Tennessee's larger cities apply their own permitting and, in some cases, local plumber registration on top.
Apprentice / plumber's helper
Working under a licensed plumber or contractor while learning the trade. Tennessee does not gate this with a state licence, but registered apprenticeship through a union local or an approved programme is what makes your experience verifiable later.
Employed plumber (no state credential)
An employee of a licensed plumbing contractor performs plumbing work in Tennessee without a state licence of their own. The contractor's licence is what authorises the work, which is why so many Tennessee plumbers never hold a state credential.
Local journeyman card
Where a Tennessee county or city issues journeyman plumber cards, that card is the individual credential — and it is valid only inside the issuing jurisdiction. Check with the local building or licensing department, because coverage is uneven across the state.
Tennessee plumbing contractor licence
The state credential this page centres on, issued by the TN Board for Licensing Contractors. It authorises contracting plumbing work to the public and normally requires a qualifying individual, examinations, liability insurance and a bond or financial showing.
Qualifying individual
The person whose experience and examination results qualify the licence. Losing the qualifying individual puts the business licence at risk, which is why contractors treat that person's retention as a compliance matter rather than an HR one.
Backflow prevention assembly tester
A separate certification to test and certify backflow assemblies, with its own training, examination and recertification cycle, generally administered through water utilities or an approved certifying body.
Medical gas and specialty endorsements
Credentials for medical gas and vacuum piping in healthcare facilities under NFPA 99 and ASSE 6010, and other defined specialist work. They are additional to the plumbing credential, never a substitute for it.
Exact experience hours and fees vary by license type and can change, confirm current requirements on the TN Board for Licensing Contractors Plumber program page.

How do you get a Tennessee contractor-level Plumber license?
- 1
Establish who actually licenses the work you intend to do
Tennessee licenses plumbing contractors through the Board for Licensing Contractors at the Department of Commerce and Insurance, and it also operates a Limited Licensed Plumber credential for smaller-value work — but it does not run a conventional statewide journeyman ladder. Before you invest in an examination or a course, establish which body governs the work in front of you — the TN Board for Licensing Contractors for the state credential, and the local building or licensing department for anything issued at city or county level. The Limited Licensed Plumber is the Tennessee feature worth understanding: it authorises plumbing work below a statutory project value, giving a route into independent work short of the full contractor licence, while projects above the threshold require the contractor licence with its financial statement and monetary limit. Tennessee's larger cities apply their own permitting and, in some cases, local plumber registration on top.
- 2
Build verifiable supervised experience
Plumbing licensing everywhere rests on time under supervision, and Tennessee is no exception. Registered apprenticeship through a UA local or a state-approved programme is the cleanest route, because it produces classroom instruction and documented hours in a form the TN Board for Licensing Contractors recognises, and it is paid throughout. Whatever route you take, the test at the end is whether someone with direct knowledge of your work can verify it, so keep employer records, pay records and job descriptions.
- 3
Prepare for the code examination the TN Board for Licensing Contractors uses
The examination is built on the plumbing code Tennessee enforces, with state and sometimes local amendments layered on top, and it covers water supply and distribution, drain, waste and vent systems, sizing and venting, isometrics, gas piping where the credential includes it, backflow prevention and safety. It never covers the electrical code. The Limited Licensed Plumber is the Tennessee feature worth understanding: it authorises plumbing work below a statutory project value, giving a route into independent work short of the full contractor licence, while projects above the threshold require the contractor licence with its financial statement and monetary limit. Tennessee's larger cities apply their own permitting and, in some cases, local plumber registration on top. Confirm the current adopted code and edition with the TN Board for Licensing Contractors before buying a code book, because an out-of-date edition is a common and avoidable reason to fail.
- 4
Apply, sit the examination and receive the credential
File the application with the Tennessee Board for Licensing Contractors, Department of Commerce and Insurance, with your verified experience, identification and the current fee, and sit the examination once you are approved. Fees, application review times and examination scheduling are set by the TN Board for Licensing Contractors and by whichever testing vendor it contracts, and both change — take the current figures from the board rather than from a third-party summary. The Department of Commerce and Insurance licence search shows Tennessee contractor classifications and monetary limits as well as limited licensed plumbers.
- 5
Add the business requirements and keep everything current
Contracting plumbing work to the public in Tennessee requires the business side as well as the technical side: liability insurance, in most cases a bond, and where the TN Board for Licensing Contractors requires it a financial showing supporting your monetary limit. Renew on the board's cycle and complete any continuing education required. If your work crosses into other jurisdictions, check each one's permitting and registration rules before you start, because enforcement is local even where licensing is not.
Does a Tennessee plumber license transfer to other states?
Plumbing reciprocity is real but narrow. Where Tennessee has arrangements, they typically apply to a specific licence class held actively and in good standing for a defined period in a state whose requirements the Tennessee Board for Licensing Contractors, Department of Commerce and Insurance considers substantially equivalent, and they usually waive the trade examination rather than the whole application — expect the business or law portion, the fee, the experience verification and any state-specific requirements to remain. The states covered and the classes covered change, and an arrangement that existed when a colleague moved may not exist now. Confirm the current position with the TN Board for Licensing Contractors before relying on an out-of-state licence, and do not let the original licence lapse in the meantime, because it is usually the basis the application rests on.
Reciprocity agreements change, always confirm the current list and requirements on the TN Board for Licensing Contractors Plumber program page before applying.
How much does a Tennessee plumber license cost, and how long does it take?
The apprenticeship is the real investment and it is paid, so most Tennessee plumbers reach licensure without tuition debt. The fees to budget for are the application and examination fees charged by the Tennessee Board for Licensing Contractors, Department of Commerce and Insurance and whichever testing vendor it contracts, the code book for the current adopted edition, and renewal with any continuing education. A business contracting to the public adds liability insurance and a bond, priced as an annual premium rather than the face amount. Every one of these is set separately and revised periodically, so take current figures from the TN Board for Licensing Contractors's published fee schedule rather than from a third-party total.
Tennessee plumbing exam content and license verification
What does the Tennessee exam cover, and how do you check a licence?
There is no national plumbing examination. Tennessee tests you on the plumbing code it enforces, with state amendments, covering water supply and distribution, drain, waste and vent systems, fixture and pipe sizing, venting, drainage isometrics, gas piping where the credential covers it, backflow prevention and safety. The Limited Licensed Plumber is the Tennessee feature worth understanding: it authorises plumbing work below a statutory project value, giving a route into independent work short of the full contractor licence, while projects above the threshold require the contractor licence with its financial statement and monetary limit. Tennessee's larger cities apply their own permitting and, in some cases, local plumber registration on top. Boards contract testing to vendors such as PSI, Prometric or ICC or administer examinations themselves, and whether the examination is open book with an approved code book — as many plumbing examinations are — is set by the TN Board for Licensing Contractors rather than nationally. Confirm the current adopted code edition, the testing vendor and the passing standard with the Tennessee Board for Licensing Contractors, Department of Commerce and Insurance before scheduling, because all three are revised periodically and an out-of-date code book is a common cause of an avoidable failure.
How to verify a Tennessee plumber license
The Department of Commerce and Insurance licence search shows Tennessee contractor classifications and monetary limits as well as limited licensed plumbers. Check the credential type rather than merely that one exists: in plumbing the difference between an individual licence, a business credential and a specialty endorsement determines what the holder may lawfully do, and a customer or general contractor checking only that "he's licensed" learns very little. Confirm the status and expiry too, and where a business is contracting the work, confirm its liability insurance and bond as well as its licence.
