Tennessee requires Contractor licensing through the Department of Commerce and Insurance, Board for Licensing Contractors. The CE (Electrical) classification covers full electrical including low-voltage. The LV (Limited Voltage / Low-Voltage) specialty classification specifically covers low-voltage scope under 50 volts. A separate Alarm Systems Contractors license through the Department of Commerce and Insurance is required for monitored burglar / fire alarm work.

Common pitfalls

Mistakes we see installers make when navigating Tennessee licensing.

  • The contractor licensing threshold is $25,000 - smaller jobs may not require a CE license, but alarm work always requires the separate Alarm Systems Contractors license regardless of project size.
  • Tennessee requires a financial statement from a CPA showing the contractor's monetary limit. Your license is capped at the financial number; bidding above your monetary limit invalidates the license on that job.
  • Memphis, Nashville, Knoxville, and Chattanooga each add local permits and inspection requirements on top of the state license.
