How to get licensed
- 1
Meet the prerequisites
Be at least 18 years old, pass a criminal background check. The LLP application requires the applicant to certify they are at least 18 years of age. Applicants must disclose any felony conviction; a felony disclosure triggers a requirement to submit a background investigation report from the Tennessee Bureau of Investigation (TBI) and a parole-officer reference, with the Board judging cases on their merits (may include a Board-meeting interview).

Complete approved training
Complete the required training. Tennessee has no statewide journeyman plumber license and no fixed classroom training-hour requirement for the Limited Licensed Plumber (LLP), the state's individual, exam-based plumbing credential (for projects under $25,000). State law (T.C.A. § 62-6-406) requires documented proof of at least 1 year of plumbing experience — verified via a completed experience/verification form, notarized employer/client letters, or an existing local-government plumbing license — rather than a classroom-hour count, so hours is left null. Plumbers working on projects of $25,000+ instead need a Contractor's License with a Mechanical Plumbing classification (CMC-A or CMC), which requires 3 years of documented plumbing experience and Board pre-approval before sitting the trade exam. Many Tennessee cities/counties also run their own separate local journeyman/master plumber licensing programs with their own training requirements. [1]

Limited Licensed Plumber (LLP) Trade Examination
Pass the Limited Licensed Plumber (LLP) Trade Examination (fee: $53). 40 scored multiple-choice questions, 135 minutes, open-book (approved code/reference books allowed); 73% (29 of 40) required to pass. Content covers General Knowledge/Math, General Requirements (administrative, structural, backflow, materials/supports, joints/connections, storm drains, testing), Water Supply and Distribution, Fixtures (incl. water heaters), Drain/Waste/Vent Systems, Traps/Cleanouts/Interceptors, Isometric Analysis, Gas Appliances and Piping, and OSHA Safety. Retake fee is also $53; a review-only session is $40. Fee sourced from PSI's Tennessee LLP Candidate Information Bulletin (revised 2/5/2026) — the most recent published fee figure at the time of this record; confirm current pricing directly with Prov given the mid-2026 administrator transition noted above.

Fees
| Fee | Amount |
|---|---|
| Application fee [3] | $75 |
| License fee [3] | None specified |
| Renewal fee [3] | $50 |
| Limited Licensed Plumber (LLP) Trade Examination [2] | $53 |
| Reinstatement (LLP expired more than 3 months) [3] | $80 |
| Late renewal penalty, per month (up to 3 months) [3] | $10 |
| Duplicate license [3] | $5 |
Per the Board's official fee schedule, the $75 fee covers Initial/Reinstatement issuance of the LLP license — the Board does not itemize a separate post-exam 'license' fee beyond this, so license is left null. The $53 PSI exam fee is paid directly to the exam vendor, not the Board, and is recorded separately under exams.
Renewal & continuing education
Renew every 2 years.
The LLP license is valid for 2 years (renewal fee $75 per third-party sources describing the license term, though the Board's official fee table lists the standalone 'Renewal' transaction fee as $50 — both figures are from Board-linked material; the $50 figure is taken directly from the Board's live fee-schedule page and is used here). Renewal opens once within 90 days of expiration and should be submitted at least 30 days before expiration; the grace period is 3 months, with a $10/month late fee, after which the license must be reinstated ($80: a $50 new-application fee plus a $30 late penalty). No continuing-education hour requirement is listed for LLP or LLE licensees on the Board's renewal page (unlike BC-A contractors, who need 8 CE hours per renewal), so ceHours is left null.
Reciprocity
No reciprocity or endorsement route was found.
Tennessee's own regulatory-board page for Limited Licensed Plumbers states plainly that 'the LLP exam is not reciprocal with other states license exams' — an out-of-state plumbing license cannot be used to waive the Tennessee LLP trade exam. (Within Tennessee, a local government plumbing license/registration can be submitted in place of a fresh LLP exam score on the application.) No interstate plumbing licensure compact exists, and Tennessee is not a member of one for this occupation. Retrieved via archive snapshot 2026-02-11 of the Board's llp.html page, which has since been reorganized into the current 'How to Get a License' page structure cited elsewhere in this record.

Frequently asked questions
Does Tennessee require a state plumbing license?
Only in municipalities that use the Division of Fire Prevention for plumbing permits/inspections, and only for work under $25,000 (that credential is the Limited Licensed Plumber, or LLP). Plumbing projects of $25,000 or more require a Contractor's License with a Mechanical Plumbing classification instead. Always check with local code enforcement, since many cities and counties run their own separate journeyman/master plumber licensing programs.
What do I need to get a Tennessee LLP license?
A photo ID and Social Security number, proof of at least 1 year of plumbing experience, and a passing score on the LLP trade exam. The initial application fee is $75.
Who administers the Tennessee LLP exam and what does it cost?
PSI Services LLC has administered it (40 questions, 135 minutes, 73%/29 of 40 to pass, open-book, $53 fee), but the Board is transitioning exam administration to a new vendor, Prov, for new scheduling beginning July 1, 2026.
How much does an LLP license cost to renew?
The Board's fee schedule lists a $50 renewal fee, with a 3-month grace period and a $10/month late fee after expiration; reinstatement after the grace period costs $80.
Can I transfer an out-of-state plumbing license to Tennessee?
No — the Board states the LLP exam is not reciprocal with other states' license exams, so an out-of-state license does not exempt you from Tennessee's LLP trade exam.
