1.2 License Classifications & Project Thresholds

License Classifications & Project Thresholds

1. Statutory Monetary Thresholds for Prime Contractors

Tennessee law establishes explicit financial triggers that define when a contractor license is legally mandatory. Under TCA § 62-6-102(4)(A), a "contractor" is defined as any individual, firm, partnership, corporation, or joint venture that undertakes to, or submits a bid to, construct, alter, repair, add to, subtract from, improve, move, wreck, or demolish any building, highway, road, railroad, excavation, or other structure.

The Prime Contracting Threshold: $25,000

• The Trigger Amount: A contractor license issued by the Board for Licensing Contractors is legally required BEFORE submitting a bid, executing a contract, or commencing work on any project where the total cost or valuation of the project is $25,000 or more.
• Single Project Aggregate: The $25,000 threshold includes the total cost of all materials, labor, equipment, supervision, overhead, and profit. A contractor cannot evade the statutory threshold by splitting a single project into multiple smaller sub-contracts valued at under $25,000 (a practice known as "contract splitting" or "fragmentation"). If the aggregate value of the total improvement is $25,000 or more, licensing is mandatory.
• Owner-Builder Exemption Limit: Property owners building a single-family residence for their own personal occupancy are exempt from licensing; however, if they build more than one residence within a 24-month period, state law creates a rebuttable presumption that the owner is acting as an unlicensed contractor.

2. Subcontractor Licensing Thresholds

Unlike many states where licensing applies exclusively to prime contractors, Tennessee imposes direct statutory licensing requirements on specific subtrades working under a prime contractor.

Major Subtrade Licensure Rules

Subcontractors contracting directly with a licensed prime contractor must hold an active Tennessee contractor license in their respective specialty classification if their subcontract amount meets or exceeds specific statutory dollar amounts:

1. Electrical Subcontractors: Must be licensed if performing electrical work valued at $25,000 or more (including labor and materials).
2. Plumbing Subcontractors: Must be licensed if performing plumbing work valued at $25,000 or more.
3. HVAC / Mechanical Subcontractors: Must be licensed if performing heating, ventilation, air conditioning, or refrigeration work valued at $25,000 or more.
4. Masonry Subcontractors: Must be licensed if performing structural or non-structural masonry work (brick, block, stone, exterior insulation finish systems) valued at $100,000 or more (including labor, materials, and equipment).
5. Roofing Subcontractors: Effective under state regulations, roofing subcontracts valued at $25,000 or more require a license under the BC-9 or specialty roofing classification.

3. Major Tennessee License Classifications

The Board categorizes contractor licenses into major divisions and sub-classifications. The license certificate issued by the Board explicitly lists the authorized Classification Code(s) and the assigned Monetary Limit.

Major Classification Categories

• BC - Building Construction: This broad classification authorizes general building construction activities and is subdivided into:
  • BC-A (Residential): Single-family residences, duplexes, and multi-family residential structures up to 4 units.
  • BC-B (Commercial): Commercial buildings, retail, industrial structures, institutional facilities, office complexes.
  • BC-C (Small Commercial): Commercial structures up to a limited square footage and valuation.
  • BC (Combined BC-A, B, C): Comprehensive commercial, industrial, and residential building authorization.
• CE - Electrical Construction: Covers high-voltage distribution, commercial power wiring, control systems, low-voltage telecommunications, and solar electrical integration.
• CMC - Mechanical / Plumbing Construction: Covers mechanical systems, including:
  • CMC-A: HVAC, refrigeration, and environmental air control systems.
  • CMC-B: Commercial and residential plumbing systems.
  • CMC-C: Process piping, boiler installations, and industrial piping.
• HRA - Heavy Construction: Earthmoving, grading, bridge construction, foundation piling, dam construction, utility municipal pipelines, and marine construction.
• HC - Highway, Railroad & Airport Construction: Asphalt paving, concrete paving, highway bridges, grading, airport runway construction, and railway infrastructure.
• LLE / LLP - Limited Licenses:
  • LLE (Licensed Limited Electrician): Authorizes electrical work on projects under $25,000 in local jurisdictions that do not have local licensing boards.
  • LLP (Licensed Limited Plumber): Authorizes plumbing work on projects under $25,000 in participating municipalities.

4. The Bid Envelope Subcontractor Listing Law (TCA § 62-6-119)

One of the most heavily tested statutes on the Tennessee Business and Law examination is the Subcontractor Bid Envelope Requirement codified under TCA § 62-6-119.

Statutory Envelope Disclosure Rules

When a prime contractor submits a written, sealed bid for any public or private construction project where the total prime contract amount is $25,000 or more, the prime contractor MUST write four specific pieces of information on the outside of the sealed bid envelope for the prime contractor AND for each of the following four key subtrades:

1. Electrical Subcontractor (if work is $25,000+)
2. HVAC / Mechanical Subcontractor (if work is $25,000+)
3. Plumbing Subcontractor (if work is $25,000+)
4. Masonry Subcontractor (if work is $100,000+)

Mandatory Listed Envelope Details

For the Prime Contractor and each required subcontractor, the outside of the envelope must display:

• The legal Name of the Contractor/Subcontractor
• The Tennessee Contractor License Number
• The License Expiration Date
• The License Classification Code (e.g., CE, CMC-A, BC-B)

Critical Legal Consequence: If a prime contractor fails to list any required subcontractor on the outside of the bid envelope, or if a listed subcontractor has an expired license or insufficient monetary limit, the bid is legally void. The awarding authority (city, county, state agency, or private owner) is strictly forbidden by law from opening or reading the bid.

5. Monetary Limits & Financial Requirements

Every contractor license issued in Tennessee carries a specific Monetary Limit indicating the maximum single project contract value the licensee is permitted to bid or perform.

Financial Formulas for Monetary Limits

The Board determines a contractor's monetary limit based on financial statements prepared by an independent Certified Public Accountant (CPA):

• Working Capital Rule: Working Capital = Current Assets minus Current Liabilities. The base monetary limit is typically set at 10 times Working Capital.
• Net Worth Rule: Net Worth = Total Assets minus Total Liabilities. The base monetary limit is also capped at 10 times Net Worth.
• Lesser Amount Governs: The assigned monetary limit is established based on the lesser of 10 times Working Capital or 10 times Net Worth.

CPA Financial Statement Tier Requirements

• Monetary Limit up to $3,000,000: Requires a CPA Reviewed Financial Statement (or Audited Statement) prepared in accordance with GAAP.
• Monetary Limit Exceeding $3,000,000: Requires a full CPA Audited Financial Statement.
• Unlimited Monetary Limit: Requires a CPA Audited Financial Statement demonstrating working capital and net worth exceeding threshold minimums established by Board rules (typically minimum $300,000 working capital and net worth).
