Tennessee

Tennessee runs a tiered licensing system through a single primary board — the Board for Licensing Contractors — with four license types keyed to project value and trade. Separate agencies handle alarm systems, highway prequalification, and environmental abatement.

Always verify statutes, fees, and application details with the live regulator before making bidding, licensing, or legal decisions.

Frequently asked questions

Pick the tab that matches your situation. Each FAQ gives a direct answer and points you to the full detail below.

Contractors
Regulators

What is the minimum contract value that requires a contractor license in Tennessee?

The primary threshold is $25,000 or more, applying to prime contractors, construction managers, and covered subcontractors (mechanical, plumbing, HVAC, electrical, roofing). Masonry subcontractors trigger at $100,000. See Construction work regulated.

What is a Home Improvement license, and when is it required?

The Home Improvement license covers remodeling work from $3,000 to $24,999 but only in 9 specified counties: Bradley, Davidson, Hamilton, Haywood, Knox, Marion, Robertson, Rutherford, and Shelby. No exam or Board review is required, but you need insurance and a $10,000 surety bond. See Requirements.

Which subcontractor trades must be licensed?

Mechanical, plumbing, HVAC, electrical, and roofing subcontractors must be licensed at the $25,000 threshold. Masonry subcontractors trigger at $100,000. The subcontractor’s license information must appear on the bid envelope. See Construction work regulated.

Where do I go to get licensed in Tennessee?

Most work goes through the Board for Licensing Contractors. Alarm and fire sprinkler systems route to the Alarm Systems Contractors Board. Highway/bridge work routes to TDOT. Environmental abatement routes to the Department of Environment and Conservation. See Who regulates construction.

How much does it cost to get licensed?

The Contractor License application is $250 (biennial) with a $200 biennial renewal. The PSI exam fee is $55. Home Improvement licenses cost the same: $250 application, $200 renewal. LLE and LLP licenses are $50—$75 with $50 renewals. See Requirements.

What is the monetary limit on a contractor license?

The Board assigns a monetary limit on each contractor license based on the CPA-prepared financial statement. A review is required for limits at $3,000,000 or below; an audit is required above $3,000,000. The license is issued to the business entity, not the qualifying individual. See Requirements.

Can I use my out-of-state license in Tennessee?

Tennessee offers trade exam waivers with 9 states plus NASCLA accredited exams. The trade exam may be waived, but the Business and Law exam is always required, and all other application requirements still apply. See Reciprocal agreements.

What about electrical or plumbing work under $25,000?

Outside municipal code offices, electrical work under $25,000 requires a Limited Licensed Electrician (LLE) license. Plumbing under $25,000 outside municipal code offices requires a Limited Licensed Plumber (LLP) license. Both require a trade exam but no Business and Law exam. See Requirements.

Does Tennessee require a license for roofing work?

Yes. Roofing subcontractors are one of the trades that must be licensed at the $25,000 threshold. Roofing falls under the Contractor License from the Board for Licensing Contractors. See Construction work regulated.

Does Tennessee require a license for residential work?

Yes. Residential construction at $25,000 or more requires a Contractor License with the residential classification (BC-A or BC-A/r). Home improvement work from $3,000 to $24,999 in the 9 designated counties requires a Home Improvement license. See Types of licenses.

Is continuing education required?

Only for residential classification holders (BC-A or BC-A/r) whose initial license was issued after January 1, 2009. They must complete 8 hours of CE per renewal period. Other classifications have no CE requirement. See Requirements.

How does Tennessee's licensing model compare to multi-board states?

Tennessee is primarily a single-board state — the Board for Licensing Contractors handles all four license tiers. Alarm systems, highway work, and environmental abatement route to separate agencies, but the core licensing structure is centralized. This contrasts with states like Alabama (8 boards) or North Carolina (7 boards). See Who regulates construction.

How does Tennessee's $25,000 threshold compare to other states?

The $25,000 threshold is moderate. Some states trigger as low as $500 or $1,000 (Virginia at $1,000), while others like Alabama trigger at $100,000. Tennessee’s Home Improvement license creates a lower entry point at $3,000 in 9 counties. For cross-state comparison, see Licensing thresholds.

What types of construction work are regulated at the state vs. local level?

Tennessee regulates at the state level through the Board for Licensing Contractors for most construction. The Home Improvement license applies only in 9 specified counties. LLE and LLP licenses apply outside municipal code offices. Highway work routes to TDOT. Local jurisdictions may impose additional requirements beyond state licensing.

How does the monetary limit system work?

The Board assigns a monetary limit to each contractor license based on the CPA-prepared financial statement. Reviews are accepted for limits at $3,000,000 or below; audits are required above that. This creates a financial-capacity layer on top of classification, similar to North Carolina’s tier system but more granular. See Requirements.

What license classifications does Tennessee use?

Tennessee has five major classification families: Building Construction (BC) with residential, commercial, small commercial, and industrial; Heavy Construction (HC); Highway, Railroad, and Airport (HRA); Municipal and Utility (MU); and Licensed Masonry Contractor (LMC). Mechanical (MC) and Electrical (CE) are separate classification families. Environmental and specialty categories also exist. See Types of licenses.

How does reciprocity work in Tennessee?

Tennessee offers trade exam waivers with 9 states covering building, electrical, and mechanical classifications. NASCLA accredited exams are accepted for commercial general building, electrical, and journeyman electricians. The Business and Law exam is always required. See Reciprocal agreements.

What exam requirements exist across the license tiers?

The Contractor License requires a Business and Law exam (passing score 73, PSI-administered) plus trade exams for certain classifications. Home Improvement licenses require no exam. LLE and LLP require trade exams only (passing score 72). Plumbing contractors need 3 years of experience. See Requirements.

What are the renewal cycles?

Contractor and Home Improvement licenses are biennial. LLE and LLP licenses are biennial. The Board meets 6 times per year to approve Contractor License applications. TDOT prequalification has its own renewal cycle. See Requirements.

How does the 9-county Home Improvement rule affect regulatory analysis?

The Home Improvement license (covering $3,000 to $24,999 in Bradley, Davidson, Hamilton, Haywood, Knox, Marion, Robertson, Rutherford, and Shelby counties) creates a geographic exception to the normal $25,000 threshold. Outside these counties, work under $25,000 is regulated locally, not at the state level. This geographic variation is unusual among Southern states.

How does Tennessee compare to other Southern states?

Tennessee’s single-board model with tiered licenses is moderately complex. The monetary limit system based on financial statements is structurally similar to North Carolina’s tiers but more flexible. The 9-county Home Improvement rule is a geographic variation not common in other states. See the South region guide.

Contractors
Regulators

Start with contract value. Tennessee tiers everything from that number.

The primary contractor license threshold is $25,000.
Mechanical, plumbing, HVAC, electrical, and roofing subcontractors must also be licensed at $25,000; masonry subcontractors at $100,000.
Home Improvement licenses cover $3,000—$24,999 but only in 9 counties.
Outside municipal code offices, electrical work under $25,000 requires a separate LLE license and plumbing requires an LLP.
The Board assigns a monetary limit on each contractor license based on the CPA-prepared financial statement.
Highway and bridge work routes to TDOT, not the Board for Licensing Contractors.

Readiness checklist

Four things you need to confirm before you can treat Tennessee as “ready” for a bid or an application. If any of these are unclear, you are not ready yet.

Classify the project lane

Identify whether the work is general construction, a home improvement project, a limited electrical or plumbing job, highway/bridge, alarm system, or environmental abatement.

Apply the right threshold test

Check $25,000 for contractor, $3,000 for home improvement (9 counties), $100,000 for masonry sub, or confirm whether LLE/LLP applies under $25,000.

Route to the correct regulator

Most work goes through the Board for Licensing Contractors. Highway, alarm, and environmental work route to separate agencies.

Confirm the requirement set

Confirm exams, experience, fees, insurance, bond, renewal cycle, and reciprocity rules for the exact license type before filing.

If you can identify lane, threshold, regulator, and requirement set, you have the minimum package needed for a Tennessee readiness check.

Construction work regulated

Tennessee’s licensing triggers depend on contract value, trade, and — for home improvement — which county the project is in.

Work lane	What triggers regulation
Prime contractor (general)	$25,000 or more
Subcontractor — mechanical, plumbing, HVAC, electrical, roofing	$25,000 or more
Subcontractor — masonry	$100,000 or more
Home improvement (remodeling)	$3,000 to $24,999 in 9 specified counties
Limited Licensed Electrician (LLE)	Electrical work under $25,000 outside municipal code offices
Limited Licensed Plumber (LLP)	Plumbing work under $25,000 outside municipal code offices
Highway and bridge construction	TDOT prequalification required

The nine Home Improvement counties are Bradley, Davidson, Hamilton, Haywood, Knox, Marion, Robertson, Rutherford, and Shelby. Outside these counties, work under $25,000 is regulated locally.

Common determination scenarios

If you are trying to figure out where to start, expand the scenario that is closest to your situation.

General contractor bidding a $25,000+ project

You need a Contractor License from the Board for Licensing Contractors. The Board will assign a monetary limit based on your CPA-prepared financial statement. Business and Law exam is required; trade exams apply to certain classifications.

Home remodeler in a covered county

If you are remodeling in Bradley, Davidson, Hamilton, Haywood, Knox, Marion, Robertson, Rutherford, or Shelby County and the contract is between $3,000 and $24,999, you need a Home Improvement License. No exam or Board review is required, but you need insurance and a $10,000 surety bond.

Electrician working outside city limits

If the project is under $25,000 and the area does not have a municipal code inspection office, you need a Limited Licensed Electrician (LLE) license. A trade exam is required but no Business and Law exam.

HVAC or plumbing subcontractor on a large project

Mechanical, plumbing, HVAC, electrical, and roofing subcontractors must be licensed as a contractor at the $25,000 threshold. Masonry subcontractors trigger at $100,000. The subcontractor’s license information must appear on the bid envelope.

Reciprocity request from another state

Tennessee offers trade exam waivers only — the Business and Law exam is always required. Confirm your state and classification are covered in the reciprocal agreements section below.
