What Is a Tennessee Limited Licensed Plumber?

Tennessee defines the LLP as an individual who performs qualifying plumbing work with a total project cost of less than $25,000 and who is required to hold the state limited plumber credential.

Plumbing work within the LLP framework can include work inside residential or commercial buildings involving:

• Water supply piping.
• Water distribution systems.
• Drain, waste, and vent systems.
• Plumbing fixtures.
• Water heaters.
• Traps and cleanouts.
• Gas supply piping within the permitted scope.
• Wastewater and sewage piping.
• Plumbing repairs and alterations.
• Installation of qualifying plumbing materials and equipment.

Tennessee's current Prov exam description says the LLP law is focused on plumbing work inside residential or commercial buildings. Plumbing performed outside those buildings, such as certain utility connections or irrigation systems, is treated differently under the statute.

The LLP Is Not a Contractor License

This distinction is important enough to deserve its own section.

Tennessee specifically states that a Limited Licensed Plumber is not considered a contractor.

That means an LLP holder should not advertise using titles such as:

• Plumbing Contractor.
• Mechanical Contractor.
• Licensed Tennessee Contractor.

You may describe yourself accurately as a Tennessee Limited Licensed Plumber when the credential applies.

If you want to perform contractor-level plumbing work of $25,000 or more, the relevant Tennessee path is generally the CMC-A Plumbing and Gas Piping contractor classification or another appropriate mechanical contractor classification.

How Much Plumbing Work Can an LLP Perform?

The key monetary line is less than $25,000 per project.

Once the plumbing project reaches $25,000 or more, the LLP is no longer the contractor-level license you need for that project.

Tennessee's posted LLP application also warns that a project cannot be divided into smaller phases or separate contracts just to remain below the contractor-license threshold.

In other words, a $30,000 plumbing job does not become two innocent little $15,000 jobs simply because the invoice printer is feeling creative.

What About Plumbing Work Under $500?

Tennessee's current LLP information states that general maintenance work costing less than $500 is exempt from the LLP requirement.

That does not remove local permitting, inspection, business, or code requirements that may apply.

Always check with the local authority before beginning work.

Step 1: Check Whether Your Local Area Accepts the LLP

This should be your first step, not your last.

Tennessee currently says the LLP license is required for plumbers performing qualifying work in municipalities that use the state's Division of Fire Prevention for permits or inspections.

Other municipalities may have:

• Their own plumbing license.
• A journeyman plumber license.
• A master plumber license.
• Their own trade examination.
• Local registration.
• Separate permit requirements.

The state specifically tells LLP candidates to contact the local government before performing work.

You can review the official Tennessee Limited Licensed Plumber page before getting started.

Step 2: Meet the Age and Experience Requirements

Tennessee's currently posted LLP application states that an applicant must be at least 18 years old.

The application also requires proof of at least one year of plumbing experience.

That experience may be supported by:

• A qualifying local plumbing license.
• Employer verification.
• Past client verification.
• Verification by a contractor or licensing agency.
• A detailed plumbing work history.

Experience may involve residential or commercial plumbing work such as:

• Water distribution.
• Drainage systems.
• Vent systems.
• Fixtures.
• Gas piping.
• Sewage piping.
• Repairs and alterations.

Tennessee may verify experience information, so list real projects and real work.

Step 3: Register for the LLP Trade Exam Through Prov

Beginning July 1, 2026, newly scheduled Tennessee Board for Licensing Contractors exams moved to Prov.

The exam you want is:

Unlike CMC-A Plumbing and Full Mechanical CMC, the LLP examination does not currently require the special contractor Board preapproval process before scheduling.

Visit Prov's Tennessee testing information for registration and scheduling.

Step 4: Understand the Current Tennessee LLP Exam

The current Prov Candidate Information Bulletin lists:

• 40 questions.
• 2-hour time limit.
• 73% passing score.
• $53 exam fee per attempt.
• Open-book format.

With two hours for 40 questions, you have an average of about three minutes per question.

That gives you more lookup time than some of Tennessee's larger contractor exams, but it still pays to know where the important plumbing tables and code sections live.

Step 5: Know the LLP Exam Breakdown

Drain, Waste, and Vent Systems is the largest section with 10 questions.

Isometrics adds another seven questions.

Those two areas alone make up more than 40% of the exam, so spend plenty of study time tracing piping and understanding DWV rules.

Step 6: Get the Current Official LLP Exam References

The June 2026 Prov bulletin lists three primary references for the LLP examination:

• International Plumbing Code, 2021.
• Mathematics for Plumbers and Pipefitters, 8th Edition.
• Plumbing Basics for Contractors, 4th Edition, 2021.

Prov allows older or newer versions of the same approved reference, but the examination is scored using the version identified in the official bulletin.

Prov also maintains an Alternate Book List for certain previously approved PSI references during the testing-provider transition through January 1, 2027.

Before buying study materials, compare the newest official reference list with the Tennessee Limited Licensed Plumber Exam Book Package from 1 Exam Prep.

Step 7: Prepare Your Books Correctly

The LLP exam is open book, but Prov has strict reference rules.

Current rules allow:

• Highlighting.
• Underlining in pen before the exam.
• Permanent tabs.
• Authorized exam references.
• A simple four-function calculator.

Current rules prohibit:

• Handwritten notes inside the books.
• Moveable or repositionable tabs.
• Post-it notes.
• Loose photocopied pages added to references.
• Photocopied books unless specifically authorized.
• Unauthorized practice exams in the testing room.

If you want references prepared for faster study, review the Tennessee LLP Highlighted & Tabbed Book Package.

Step 8: Make Drain, Waste, and Vent Your Biggest Study Priority

DWV is the biggest single exam category.

Study:

• Drainage fixture units.
• Horizontal drainage sizing.
• Stacks.
• Building drains.
• Building sewers.
• Vent sizing.
• Vent connections.
• Traps.
• Cleanouts.
• Indirect waste.

Learn where the major IPC tables are located instead of trying to memorize every number.

Step 9: Practice Plumbing Isometrics

The current exam includes seven isometric questions.

Practice identifying:

• Horizontal branches.
• Vertical stacks.
• Vent connections.
• Fixture connections.
• Changes in direction.
• Drainage routes.
• Pipe sizes.

Isometric drawings can look like somebody dropped a box of pipe fittings onto graph paper, but they become much easier with repetition.

Step 10: Study Water Supply and Fuel Gas

Water Supply and Distribution and Fuel Gas Systems each contribute four questions.

For water systems, review:

• Fixture units.
• Water service sizing.
• Distribution piping.
• Pressure.
• Valves.
• Backflow protection.

For fuel gas, review the gas-related material authorized for your current examination, including piping, appliance connections, shutoffs, sizing concepts, and safety.

Step 11: Practice Plumbing Math

Plumbing Math accounts for only two dedicated questions, but calculations can appear inside other subjects.

Practice:

• Fractions.
• Decimals.
• Measurements.
• Slope.
• Offsets.
• Area and volume.
• Unit conversions.

A plumbing exam is much less exciting when a fraction you have known since eighth grade suddenly decides to become your greatest enemy.

Step 12: Use Timed Practice

A simple LLP study plan can look like this:

1. Study the International Plumbing Code layout.
2. Review one exam subject at a time.
3. Answer practice questions.
4. Look up every missed answer.
5. Practice reaching the correct table faster.
6. Work plumbing calculations.
7. Practice isometric drawings.
8. Mix several topics together.
9. Complete 40-question timed simulations.

Step 13: Pass the LLP Trade Exam

You need at least 73% to pass.

Current Prov policy allows unsuccessful candidates to retake Tennessee examinations as many times as necessary, with no mandatory waiting period.

Each new exam attempt currently costs another $53.

Use your score report to decide what needs work before paying for another attempt.

Do LLP Applicants Need Tennessee Business and Law?

No. The LLP licensing path is different from the Tennessee contractor licensing process.

Tennessee's current LLP requirements call for the LLP trade exam and individual licensing requirements. The separate Tennessee Contractor Business and Law examination applies to contractor applicants, not the ordinary LLP licensing process.

You also do not need a contractor Qualifying Agent just to obtain an LLP license.

The LLP license is issued directly to the qualifying individual.

Does an LLP Need a Contractor Financial Statement or Monetary Limit?

No. The LLP is not a Tennessee contractor license.

The contractor licensing system uses:

• CPA financial statements or qualifying surety bonds.
• Board-approved monetary limits.
• Qualifying Agents.
• Contractor Business and Law examinations.

Those are not part of the ordinary LLP application.

The LLP already has its statutory project restriction: qualifying plumbing work must remain below $25,000.

Step 14: Complete the Tennessee LLP Application

After satisfying the exam and experience requirements, complete the Initial Limited Licensed Plumber application.

Tennessee's current main LLP page directs applicants to apply through Tennessee CORE.

The current initial application fee is $75.

Be prepared to provide or document:

• Your legal name.
• Photo identification.
• Social Security number.
• Age eligibility.
• At least one year of plumbing experience under the currently posted application.
• Proof of plumbing experience.
• LLP exam score.
• Required eligibility verification information.
• Disclosures when applicable.

Step 15: Check Business, Insurance, Permit, and Inspection Rules

Tennessee's posted LLP application states that proof of workers' compensation insurance is not required to be submitted with the LLP application itself.

That does not mean insurance laws disappear.

Depending on your business and employees, you may still need to address:

• Workers' compensation requirements.
• Business licensing.
• Local tax registration.
• Plumbing permits.
• Inspections.
• Local plumber registration or licensing.

The safest habit is simple: check the local authority before taking the job.

When Should You Upgrade to CMC-A?

LLP is useful for smaller plumbing projects, but it has a clear ceiling.

If you want to:

• Contract plumbing projects of $25,000 or more.
• Operate as a Tennessee plumbing contractor.
• Advertise as a plumbing contractor.
• Build a plumbing business around larger commercial projects.
• Take on larger mechanical plumbing and gas piping contracts.

then the next license to examine is generally CMC-A Plumbing and Gas Piping.

CMC-A has a different licensing structure, including Board exam preapproval, Business and Law, financial qualification, insurance, and an approved monetary limit.

How Long Is the Tennessee LLP License Valid?

Tennessee's currently posted LLP application describes the $75 initial fee as a two-year license fee.

The current LLP renewal fee is $50.

Tennessee currently gives LLE and LLP licensees a three-month renewal grace period.

A late renewal during that period carries a current $10 per month late fee.

Once the license has been expired for three months or longer, Tennessee requires the individual to go through the applicable new or reinstatement licensing process.

Renewal is completed through CORE.

Frequently Asked Questions

Here are common questions about becoming a Tennessee Limited Licensed Plumber.

Key Takeaways

• The Tennessee LLP is an individual limited plumber license, not a contractor license. It covers qualifying plumbing projects costing less than $25,000 where the LLP is required and accepted.
• Local rules matter. Tennessee tells plumbers to verify whether the local municipality accepts the state LLP or requires its own plumbing credential, permits, or inspections.
• The currently posted application requires at least one year of plumbing experience. Applicants must also be at least 18 and pass the LLP trade examination.
• The current Prov exam has 40 questions, two hours, a 73% passing score, and a $53 fee. DWV systems and isometrics make up the largest portion of the test.
• The LLP path is much simpler than a contractor license. There is no normal contractor Business and Law exam, Qualifying Agent, CPA financial statement, or Board-issued monetary limit for the LLP itself.

Final Thoughts Before You Start

The Tennessee Limited Licensed Plumber credential can be a practical path for plumbers who want to perform smaller plumbing projects without moving immediately into the full mechanical contractor licensing system.

The most important thing is understanding what the LLP is and what it is not.

It is an individual plumbing license. It is not a contractor license. The work must remain below $25,000 per project, and Tennessee does not allow someone to split a larger project into smaller contracts simply to stay under that threshold.

Local rules are just as important. Before testing, verify whether the city or county where you plan to work actually uses or accepts the state LLP. Some jurisdictions operate their own plumber licensing systems.

If the LLP is the correct credential, document your plumbing experience carefully. Tennessee's currently posted application requires proof of at least one year of plumbing experience.

Then prepare for the Prov exam.

The current examination is manageable at 40 questions, but DWV systems and isometrics make up a large percentage of the test. Learn the International Plumbing Code layout, practice tracing drainage and vent systems, work plumbing calculations, and become comfortable using the approved references under a timer.

The open-book format is helpful only if you already know the books. Highlight important material, use permanent tabs where permitted, and practice locating answers before exam day.

Once you pass, complete the Tennessee application and pay the current $75 fee. Remember that passing the test does not mean you can ignore local permits, inspections, business licensing, or insurance laws.

As your business grows, pay attention to the $25,000 line. If larger plumbing contracts become part of your future, it may be time to move from the LLP path to the Tennessee CMC-A Plumbing and Gas Piping contractor classification.
