Tennessee trade license reciprocity

How local licensing works. T.C.A. Title 62, Chapter 6 gives the Board for Licensing Contractors the CE contractor license (business-level, $25,000 and up, accepted by every jurisdiction) and the LLE (individual, under $25,000, valid only where the state inspects). Local governments that operate their own electrical inspection programs may license electricians for smaller work under their own codes, and the state publishes a list of exempt jurisdictions that do not accept the LLE. Every one of them accepts a state CE contractor license for permits, but none accepts another city's or state's journeyman card by rule.

Nashville (Metro Codes and Building Safety). The Mechanical, Plumbing, and Electrical Examiners and Appeals Board examines and licenses Master Electricians, Equipment Installers, Low Voltage Installers and Journeyman Electricians. A journeyman applicant must show completion of an electrical construction apprenticeship program or regular employment as a journeyman under an electrical contractor or master electrician, submit employer verification letters and a character letter, be approved by the Chief Electrical Inspector, and pass the Prov-administered Metro journeyman exam with 70% (30-day wait to retest). The application asks whether the applicant holds a master license in another city or state but describes no exam waiver.

Memphis / Shelby County (Office of Construction Code Enforcement). The joint Memphis and Shelby County Electrical Code licenses Journeyman Electricians and Linemen (age 20, three years of experience in the electrical field immediately preceding application, application in person with three industry recommendations, 30-day investigation, exam before the Electrical Code Advisory Board; exam $50, annual renewal $50) and registers apprentices ($12). Journeymen work under a licensed Master Electrician who pulls the permit. No reciprocity provision appears in the code.

Knoxville (Plans Review & Inspections). Knoxville is on the state's exempt list and requires everyone pulling a permit to hold a city registration matching their qualifications (state contractor, homeowner, or unlicensed/LLE-LLP registration). The city's own electrical exam, experience and fee details are not published on the pages found; contact 865-215-4311.

Chattanooga (Land Development Office). Issues a Journeyman electrical license ($55, two-year term) to applicants with 3 years or 6,000 documented hours of experience with an electrical contractor who pass the city test, and a separate 'state certified' journeyman registration on the same terms; a Board of Electrical Examiners oversees testing. No reciprocity is mentioned.

Out-of-state holders. The state has no journeyman license to endorse, the LLE has no reciprocity, and the four largest local programs publish no exam waiver for other jurisdictions' journeyman cards. Practical routes are: pass the local journeyman exam in each exempt jurisdiction where you will work; take the LLE exam ($50 license, no experience required) for sub-$25,000 work in fire-marshal counties; or, for independent contracting, obtain the state CE contractor license, which every jurisdiction accepts.

State CE contractor license (business level). Required statewide for electrical projects of $25,000 and up and accepted by every local jurisdiction for permits, but it is a business license, not a personal master credential. Requirements: qualifying agent (owner, officer or full-time employee) passes the Tennessee Business & Law exam and the Electrical (CE) trade exam administered by Prov; reviewed or audited financial statement less than 12 months old (or a contractors' surety bond at 50% of the requested limit from July 1, 2026) setting a monetary limit of 10 times the lesser of working capital or net worth ($300,000 of each for an unlimited limit); general liability insurance scaled to the limit; workers' compensation or exemption; $250 initial fee, $200 renewal every two years; exam scores valid about two years. Trade exam waiver (the only state reciprocity): a contractor licensed in Alabama, Louisiana, Mississippi, North Carolina, Ohio, South Carolina or West Virginia whose board verifies a comparable electrical exam on the Request for Contractor License Verification form, or who passed the NASCLA Electrical exam, files that verification in place of the CE trade exam score. The Business & Law exam is never waived, applicants with discipline, open complaints or felonies are ineligible, and the waiver cannot be used for the LLE. Arkansas's agreement covers only building classifications, not electrical.

Nashville (Metro Codes and Building Safety). The Mechanical, Plumbing, and Electrical Examiners and Appeals Board issues the Metropolitan Master Electrician certificate. Applicants need six years of experience (an electrical engineering degree may substitute), employer verification letters, a character letter and approval by the Chief Electrical Inspector, then pass the Prov-administered Metro master exam with 70%. The application asks whether the applicant holds a master license in another city or state and how long, but no exam waiver is described. Nashville registers state CE contractors separately.

Memphis / Shelby County (Office of Construction Code Enforcement). The Master Electrician license (Sec. 1305 of the joint electrical code) requires age 24 and either an electrical engineering degree plus two years of installation experience or four certified years as a journeyman; application in person with three industry recommendations, 30-day investigation, exam before the Electrical Code Advisory Board on theory, installation, the NEC and local codes. Fees: exam $150, initial license $100, active renewal $150. A separate Electrical Contractor license ($150 exam, $150 license, $150 registration) must be held by or employ a master; state-certified CE contractors register for $150 instead of testing. No reciprocity provision appears in the code.

Chattanooga (Land Development Office). The Class I electrical license is the contractor/master credential: three or more years as a journeyman or plant electrician (or three years as a Class II residential contractor, a prior Class I license, a Tennessee PE license, or equivalent), city examination, $415 per two-year term. A Board of Electrical Examiners oversees testing; no reciprocity is mentioned.

Knoxville (Plans Review & Inspections). Knoxville is on the state's exempt list and requires a city registration to pull permits; a state CE contractor registers directly. Details of Knoxville's own electrical contractor/master exam and fees are not published on the pages found (865-215-4311).

Out-of-state holders. No Tennessee city or the state endorses another state's master license as such. The realistic paths are: (1) obtain the state CE contractor license, using the trade-exam waiver if licensed in AL, LA, MS, NC, OH, SC or WV or NASCLA-tested, which every jurisdiction accepts; or (2) apply for the local master license in each exempt jurisdiction where you will work, documenting the experience required there and passing the local exam.

How local licensing works. The Board for Licensing Contractors regulates HVAC only through the CMC/CMC-C contractor license (projects of $25,000 and up). Anything below that threshold is regulated by the city or county, and roughly two dozen 'exempt jurisdictions' run their own mechanical inspection programs and licenses. Each jurisdiction's card is valid only there, and none of the pages below publishes a reciprocity or exam-waiver rule for out-of-state journeyman licenses.

Nashville (Davidson County). The Board of Mechanical, Plumbing and Electrical Examiners and Appeals issues Master Mechanical, HVAC&R, and Gas and Appliance certificates to individuals; there is no Nashville journeyman mechanical card. Technicians work as employees of a firm registered with a Metro certificate holder or a state CMC/CMC-C licensee ($40,000 permit bond, $300,000 liability insurance, Davidson County business license).

Memphis and Shelby County. The joint Office of Construction Code Enforcement licenses First-Class (4 years' experience, unlimited) and Third-Class (2 years, equipment up to 15 tons or 15 hp) Mechanical Contractors after a written exam, with a $150 registration, $110 annual renewal and a $25,000 permit bond, and registers state CMC licensees for $150. The mechanical code creates no journeyman mechanic license; employees work under a licensed mechanical contractor who must supervise them and furnish their names on request.

Knoxville. Permits are pulled under a State Contractor Registration (CMC/CMC-C), a Homeowner Registration, or an Unlicensed / State Limited License registration; the city's page does not describe a journeyman HVAC card, and its own mechanical license application is not posted online, so anyone planning to work in Knoxville should call Plans Review & Inspections at 865-215-4311.

Chattanooga. The Board of Mechanical Examiners licenses Journeyman Mechanics: three or more years (2,000 hours per year) as a registered journeyman or HVAC/sheet-metal helper, or a previously held unrevoked journeyman or HVAC mechanic license from Chattanooga or any other governmental agency, or other experience acceptable to the Board; $75 per two-year cycle; application through the OpenGov portal, after which the clerks send testing information. Holding a card from another jurisdiction makes an applicant eligible to sit the Chattanooga exam but does not waive it.

Out-of-state holders. No Tennessee jurisdiction found publishes reciprocity for journeyman HVAC licenses. In Nashville, Memphis and Knoxville a journeyman simply works as an employee of a licensed or registered mechanical contractor; in Chattanooga the out-of-state card supports eligibility for the local exam.

State contractor route (CMC / CMC-C). Required statewide for projects of $25,000 or more and accepted by the cities as a substitute for their own master cards for permit purposes (Nashville registers CMC/CMC-C firms for $100 with a $40,000 bond and $300,000 liability certificate; Memphis/Shelby County registers state mechanical licensees for $150). Requirements: Business & Law exam plus the CMC-C or CMC trade exam ($50 pre-approval for CMC), $250 application fee, reviewed or audited financial statement or a surety bond of at least 50% of the monetary limit (from July 1, 2026), general liability and workers' compensation insurance. Trade-exam waiver, on verification by the other board that the qualifying agent passed a comparable exam: Alabama HVAC (CMC-C), Louisiana Mechanical (CMC), Mississippi Mechanical (CMC), Ohio HVAC (CMC-C), South Carolina HVAC (CMC-C), West Virginia Mechanical (CMC). The Board stresses the waiver applies only to the trade exam, cannot be used by applicants with discipline, open complaints or felony convictions, and does not allow another state's license to be used in Tennessee.

Nashville (Davidson County). The Board of Mechanical, Plumbing and Electrical Examiners and Appeals issues the Master Mechanical certificate (six years' experience) and HVAC&R certificate (four years); a mechanical engineering degree may substitute. The application asks for licenses held in other cities or states, employer confirmations and a recommendation letter; the Chief Mechanical Inspector approves, Prov administers the exam (70% to pass, 30-day retest wait). The certificate holder then registers the firm as a Metropolitan Mechanical Gas Contractor with a Davidson County business license, $40,000 permit bond and $300,000 liability certificate. No exam waiver for out-of-state licenses is published.

Memphis and Shelby County. First-Class Mechanical Contractor (age 21, 4 years of full-time installation or design experience, unlimited scope) and Third-Class Mechanical Contractor (2 years, equipment up to 15 tons or 15 hp) after a written exam set by the Mechanical/Gas Code Board; $150 registration, $110 annual renewal, licenses expire December 31, $25,000 continuous permit bond. The mechanical code has no reciprocity provision for mechanical contractors.

Chattanooga. Master Mechanical Contractor license from the Board of Mechanical Examiners: three or more years as a Journeyman Mechanic Class 1 or 2, or a current or previously held unrevoked Master Mechanical Contractor or equivalent license from Chattanooga or any other governmental agency, or a Tennessee PE license, or acceptable education and experience; $415 per two-year cycle including the exam fee. A license from elsewhere establishes eligibility for the exam but is not stated to waive it.

Knoxville. Permits are pulled under a State Contractor Registration (CMC/CMC-C) or the other registration types on the city's permit page; the city does not publish its own mechanical license classes and fees online, so contact Plans Review & Inspections (865-215-4311).

Out-of-state holders. The only published recognition in Tennessee is the state Board's trade-exam waiver for contractors from AL, LA, MS, OH, SC and WV, which still requires the Business & Law exam and a full contractor application. The local master cards in Nashville, Memphis and Chattanooga treat an out-of-state master license as evidence of experience or exam eligibility, not as a substitute for their own examinations.

How local licensing works. T.C.A. Title 62, Chapter 6 gives the Board the CMC/CMC-A contractor license (business, $25,000 and up, accepted statewide for contracting) and the LLP (individual, under $25,000, only where the State Fire Marshal inspects). Cities and counties that run their own plumbing inspection programs may require a local journeyman or master plumber card instead of, or in addition to, the LLP. Each local card is valid only in that jurisdiction. The Board publishes no journeyman-to-journeyman reciprocity.

Nashville / Davidson County. The Mechanical, Plumbing, and Electrical Examiners and Appeals Board (Metro Code Chapter 2.76) examines applicants for master plumber, journeyman plumber and apprentice plumber certificates and issues those certificates (Codes and Building Safety, 800 President Ronald Reagan Way; 615-862-6500). Expect to sit Metro's exam unless Codes staff confirm otherwise.

Knoxville. Permits are pulled under a State Contractor registration, a Homeowner registration, or an Unlicensed / State Limited License (LLE or LLP) registration. The Plans Review & Inspections page does not describe a city-issued journeyman plumber license. No experience hours published. No out-of-state exam waiver. Accepted only where the Division of Fire Prevention inspects; many larger cities do not use that program.

State contractor route (CMC-A / CMC) — business license, not a personal master. Required statewide to bid or contract plumbing of $25,000 or more (subcontractor plumbing portion counted with materials, equipment and labor). Qualifying agent (owner, officer or full-time employee) takes the Tennessee Business and Law exam and the CMC-A or CMC trade exam after a $50 pre-approval request to [email protected]. Up to two people may take each exam; Business and Law and the trade exam need not be the same person. Application $250 at core.tn.gov. From 2026-07-01 a contractors' surety bond of at least 50% of the requested monetary limit may replace a CPA-reviewed or audited financial statement. General liability and workers' compensation (or exemption) are required on the contractor application. Trade exam waiver (not Reciprocity for a master plumber card): origin board completes the Request for Contractor License Verification in lieu of the Tennessee trade exam score. Plumbing rows: Ohio Plumbing -> CMC-A; South Carolina Plumbing -> CMC-A; Louisiana Mechanical -> CMC; Mississippi Mechanical -> CMC; West Virginia Mechanical -> CMC. Business and Law is never waived. Ineligible if discipline, open complaints or felony convictions. Cannot be used for LLP, LLE or home improvement. NASCLA accredited exams on the Board exam page are commercial building and electrical, not plumbing.

State LLP (personal, limited, not master). $75 initial, Prov LLP exam, under $25,000, Fire Prevention jurisdictions only, no exam waiver. A Tennessee CMC-A/CMC firm may still need Metro registration to pull permits; confirm with Codes (615-862-6500).

Knoxville. State Contractor registration (CMC-A/CMC) or Unlicensed/State Limited License (LLP) registration to pull permits.
