How to Check a Contractor's License in Tennessee

Tennessee requires a state license for contractors working on projects valued at $25,000 or more. The Tennessee Board for Licensing Contractors manages the system, and the state offers an online verification tool that's relatively straightforward. But the licensing structure has some nuances worth understanding — different classifications based on project dollar amounts, separate boards for specialty trades like electrical and plumbing, and exemptions for smaller home improvement work that catch people off guard.

This guide walks through exactly how to look up a contractor's license in Tennessee, what the different license classifications mean, and what to do when someone doesn't show up in the system.

Does Tennessee require a contractor license?

Yes. Tennessee requires a state license for any contractor performing construction work valued at $25,000 or more (labor and materials combined). The Tennessee Board for Licensing Contractors administers this requirement. Specialty trades — electrical, plumbing, and HVAC — have their own separate licensing requirements regardless of project value. Contractors below the $25,000 threshold are exempt from the state license, though local rules may still apply.

The Tennessee Board for Licensing Contractors, which operates under the Department of Commerce and Insurance, oversees licensing for general contractors, mechanical contractors, and several other categories. The basic rule is simple: any contractor performing construction work (including labor and materials) on a project valued at $25,000 or more must hold a state license.

Tennessee uses a classification system that ties the license to a monetary limitation — meaning the license specifies the maximum dollar value of any single project the contractor can take on. The main contractor classifications include:

• BC (Building Contractor)— General building construction including residential and commercial projects.
• BC-A (Residential Contractor, Limited)— Residential construction with a monetary limitation, typically for contractors focused on smaller residential work.
• BC-B (Residential Contractor)— Residential construction without the same limitations as BC-A, covering larger residential projects.
• MC (Mechanical Contractor)— HVAC, refrigeration, and related mechanical systems.
• MC-A (Mechanical Contractor, Limited)— Mechanical work with a lower monetary limitation.
• EC (Electrical Contractor)— Licensed through a separate process (more on this below).

Each license also carries a specific monetary limitation. A contractor with a BC classification and a $500,000 limitation cannot legally take on a $750,000 project. This detail matters — a valid license doesn't automatically mean the contractor is authorized for the size of your job.

What do I need before searching a Tennessee contractor license?

To verify a Tennessee contractor, you need at least their license number, full legal name, business name, or the city where they operate. Licensed contractors are required by state law to include their license number on contracts and advertising — if a bid doesn't show one, ask for it directly. Reluctance to provide a license number is a red flag worth taking seriously.

To verify a Tennessee contractor's license, gather at least one of the following:

• The contractor's license number (the fastest path to an exact result)
• The contractor's full name or business name
• The city where the contractor is based

How do I check a contractor's license in Tennessee?

Go to verify.tn.gov, the state's official license verification portal. Search by license number, name, or business name, and select the appropriate license type (BC, MC, etc.) from the dropdown. If you're unsure which classification applies, searching by name returns all license types associated with that person or company. The lookup is free and publicly accessible.

The Tennessee Board for Licensing Contractors maintains an online lookup tool. Go to verify.tn.gov to access the state's license verification portal. This is the official source for verifying all professional licenses issued by the state, including contractor licenses.

On the search page, you can search by license number, name, or business name. Select the appropriate license type — look for "Contractor" or the specific classification (BC, MC, etc.) from the dropdown menu. If you're not sure which classification applies, searching by name alone will return all license types associated with that person or company.

What should I verify on a Tennessee contractor license?

Confirm the license status is "Active," the classification matches your project type (BC for general building, MC for mechanical), and the monetary limitation covers your project's total cost. Also check the expiration date — Tennessee licenses renew every two years — and look for any disciplinary actions. A valid license with the wrong classification or an insufficient monetary limit still means the contractor cannot legally take your job.

The verification results will display several important data points. Here's what to focus on:

• License status— The single most important field. You need to see "Active" or "Current." Anything else — expired, revoked, suspended, inactive — means the contractor is not authorized to perform work requiring a license.
• Classification— The license type (BC, BC-A, BC-B, MC, etc.). Confirm the classification matches the type of work you need done.
• Monetary limitation— The maximum dollar value for a single project. If your project estimate exceeds this number, the contractor is not authorized to take it on.
• Expiration date— Tennessee contractor licenses must be renewed biennially. Make sure the license hasn't lapsed.
• Disciplinary actions— Any complaints, fines, or formal actions taken by the board against the contractor will appear here.

What is Tennessee's contractor monetary limitation?

Tennessee's monetary limitation is a cap on the maximum dollar value of any single project a licensed contractor can legally accept. It is printed on the license and tied to the contractor's qualifications and financial standing. A contractor with a $100,000 limitation cannot take a $120,000 project even if their license is active and their classification is correct — this is the most commonly overlooked aspect of Tennessee's licensing system.

This is the part of Tennessee's system that most homeowners overlook. A contractor can have a perfectly valid, active license and still not be authorized to work on your project if the job exceeds their monetary limitation.

Monetary limitations are set based on the contractor's qualifications, experience, and financial standing. They range widely — some contractors have limitations as low as $25,000 (the minimum threshold requiring a license), while others are approved for projects in the millions or have unlimited monetary authority.

When evaluating a contractor, compare their monetary limitation to your project's total estimated cost (labor plus materials). If your renovation is estimated at $120,000 and the contractor's limitation is $100,000, they cannot legally take the job at that price — even though their license is active and their classification is correct.

Are there home improvement exemptions from Tennessee's license requirement?

Yes. Projects under $25,000 (labor and materials combined) are exempt from Tennessee's state contractor license requirement. However, the exemption does not apply to specialty trades like electrical, plumbing, or HVAC — those require their own licenses at any project value. Nashville, Memphis, and Knoxville also have local requirements that may apply even when no state license is needed.

Tennessee has a home improvement exemption that covers certain smaller residential projects. If a project falls below the $25,000 threshold, the contractor may not need a state license. However, there are important caveats:

• The $25,000 threshold includes both labor and materials— Not just the labor portion. A project with $10,000 in labor and $18,000 in materials exceeds the threshold.
• Some counties and cities have their own requirements— Nashville (Davidson County), Memphis (Shelby County), and Knoxville all have local registration or licensing requirements that may apply even when the state license isn't required.
• The exemption doesn't cover specialty trades— Electrical, plumbing, and HVAC work each have their own licensing requirements through separate boards, regardless of project value.

Just because a contractor is exempt from the state license doesn't mean they're exempt from competence. For any project — licensed or not — you should still verify insurance and check references.

How are specialty trades licensed in Tennessee?

Tennessee licenses electrical and plumbing contractors through boards separate from the Board for Licensing Contractors. Electricians are regulated by the Tennessee Board of Electrical Contractors, and plumbers by the Tennessee Board of Plumbing Examiners. Both can be verified at verify.tn.gov by selecting the appropriate license type. HVAC falls under the Board for Licensing Contractors with an MC or MC-A classification.

Tennessee handles several major specialty trades through boards other than the Board for Licensing Contractors. If you're hiring someone for one of these trades, you need to check the right place:

• Electrical— Licensed through the Tennessee Board of Electrical Contractors. Electrical contractors need their own state license regardless of project value. Verify at verify.tn.gov by selecting the electrical contractor license type.
• Plumbing— Licensed through the Tennessee Board of Plumbing Examiners. Plumbers must pass a state exam and hold a current license. Verify through the same state portal.
• HVAC— Mechanical contractors handling HVAC work are licensed under the Board for Licensing Contractors with an MC or MC-A classification. However, some HVAC work also requires EPA certification for refrigerant handling.
• Roofing— Falls under the general contractor license if the project exceeds $25,000. Below that threshold, no state license is required, though local requirements may still apply.

A general contractor with a BC license cannot legally perform electrical or plumbing work themselves unless they also hold the appropriate specialty license. They can subcontract to licensed specialists, and you have every right to verify those subcontractors' licenses independently.

What else should I check beyond a Tennessee contractor's license?

Verify general liability insurance (Tennessee does not require it for licensure, but you should demand it), confirm the surety bond is current (required for all licensed contractors and sized to the monetary limitation), and check workers' compensation coverage. In Tennessee's construction industry, workers' comp is required for employers with one or more employees. Also check whether the contractor holds any required local business licenses in your city or county.

Confirming the license is active is the baseline. These additional checks protect you further:

• Insurance— Tennessee does not require general liability insurance as a condition of contractor licensure, but you should require it. Ask for a certificate of insurance naming you as an additional insured, and call the insurer to confirm the policy is current.
• Surety bond— Licensed contractors in Tennessee must maintain a surety bond. The bond amount is tied to their monetary limitation. This bond provides a financial backstop if the contractor fails to complete the work or violates the terms of your contract.
• Workers' compensation— Tennessee requires workers' comp coverage for employers with five or more employees (or one or more in the construction industry, with some exceptions). If workers are injured on your property and the contractor lacks coverage, you could face liability.
• Complaint history— Beyond the board's records, check the Better Business Bureau and review platforms. But remember that online reviews supplement — they don't replace — a proper license check.
• Local business license— Many Tennessee cities and counties require a separate business license or registration. Nashville, Memphis, Chattanooga, and Knoxville all have their own requirements. A valid state license does not guarantee the contractor has met local obligations.

What if I can't find a contractor in Tennessee's license database?

Start by trying name variations or searching by license number instead. Electricians and plumbers are registered under separate boards and won't appear in a general contractor search. If the project is under $25,000, the contractor may not be required to hold a state license at all. If a license is required for your project size and the contractor still can't be found, call the Board directly at (615) 741-8307 to confirm before proceeding.

A search that returns no results doesn't always mean the contractor is fraudulent. Here are common reasons and what to do about each:

• Name mismatch— The license may be under the owner's legal name rather than the company's trade name, or vice versa. Try searching by license number if you have it, or try variations of the business name.
• Wrong board— If they're an electrician or plumber, they won't appear under the Board for Licensing Contractors. Search under the Board of Electrical Contractors or Board of Plumbing Examiners instead.
• Below the $25,000 threshold— If the contractor only takes on projects under $25,000, they're not required to hold a state license. They may be perfectly legitimate but simply not in the system.
• License recently expired— The contractor may have let their renewal lapse. This happens, and some contractors continue working during the gap. An expired license means they are not currently authorized, regardless of the reason.
• They're unlicensed— If your project requires a license and the contractor doesn't have one, do not hire them. You lose significant legal protections, any permits may be invalid, and you may have no recourse through the state board if something goes wrong.

If you're stuck, call the Tennessee Board for Licensing Contractors directly at (615) 741-8307. They can confirm whether someone is licensed and provide details on their classification and monetary limitation.

The bottom line

Tennessee's contractor licensing system is built around two key numbers: the $25,000 project threshold that triggers the license requirement, and the monetary limitation on each individual license that caps what that contractor can take on. Checking the license status alone is not enough — you need to confirm the classification matches your project type and the monetary limitation covers your project's value.

Use the state's license verification portal to confirm the license is active, check the classification and monetary limitation, and look for any disciplinary history. Then go further: verify insurance, confirm the surety bond, and check that the contractor has met any local licensing requirements in your city or county.

The whole process takes less than ten minutes. That small investment of time gives you a clear picture of whether the contractor has met Tennessee's standards — and whether they're authorized for the specific project you have in mind.
