Licensing Requirements
Tennessee requires electricians to be licensed through the Tennessee Department of Commerce and Insurance (TDCI), Electrical Contracting Board. Three primary license tenders: (1) Electrical Contractor License — requires 4 years of documented journeyman-level experience, passing a business and law exam plus a trade exam administered by PSI Exams; minimum score of 70 required on both. (2) Journeyman Electrician — requires 8,000 hours of documented apprenticeship or work experience and passing a journeyman exam through PSI. (3) Residential Electrical Contractor — limited to one- and two-family dwellings; requires 2 years residential experience and passing a residential contractor exam. All licenses renew biennially. Continuing education: 16 hours required per renewal cycle for contractors, 8 hours for journeymen. Licenses are issued at the state level and are valid statewide. No separate city-level electrical license is required in Chattanooga, but the state license must be active before pulling permits.
Permit Requirements
All electrical work in Chattanooga falls under the jurisdiction of the City of Chattanooga Development Services — Electrical Inspection Division. Permits are required for new installations, panel replacements or upgrades, service changes, rewiring, and new circuit additions. Minor repairs and like-for-like device replacements (outlets, switches) generally do not require a permit. Permits are pulled online through the Chattanooga e-Permits portal or in person at 1250 Market Street. Permit fees are calculated based on project valuation. Only a state-licensed electrical contractor or the licensed homeowner for their own primary residence may pull an electrical permit. Homeowner permits are restricted to single-family owner-occupied dwellings.
Inspection Schedule
After permit issuance, rough-in inspection is required before walls are closed. Final inspection is required upon project completion before power is energized or the certificate of occupancy is issued. Inspections are scheduled through the Chattanooga Development Services portal. Typical inspection wait time is 1 to 3 business days after request. Failed inspections require re-inspection, which resets the scheduling queue. Tennessee follows the 2017 National Electrical Code (NEC) as the adopted standard for all inspections. Hamilton County properties outside Chattanooga city limits fall under Hamilton County Building Inspection jurisdiction with a similar process.
Insurance Minimums
Tennessee requires electrical contractors to carry: (1) Commercial General Liability — minimum $300,000 per occurrence for residential work; $500,000 recommended for commercial. (2) Workers' Compensation — mandatory if the contractor has 5 or more employees, including part-time; subcontractors without their own coverage count toward the employer's headcount. (3) Contractors working on state or municipal projects may face higher bonding and liability thresholds set by the contracting agency. The TDCI Electrical Contracting Board requires proof of liability insurance at time of licensure and renewal. Surety bond requirements vary by project type and are not universally mandated at the state level but are commonly required by general contractors and commercial clients.

How to Get Licensed
Verify Eligibility and Gather Experience Documentation
Determine which license type fits your situation: Electrical Contractor, Journeyman, or Residential Electrical Contractor. For Electrical Contractor, you need 4 years (approximately 8,000 hours) of journeyman-level experience. For Journeyman, you need 8,000 documented hours of apprenticeship or field work. Gather W-2s, employer letters on company letterhead, or apprenticeship completion certificates. The TDCI Electrical Contracting Board will verify this documentation — vague or unsupported experience claims will be rejected.
Submit Application to TDCI Electrical Contracting Board
Complete the official application through the Tennessee Department of Commerce and Insurance online licensing portal at tn.gov/commerce. Pay the required application fee (fees vary by license type; confirm current amounts on the TDCI website as they are subject to change). Submit all supporting experience documentation with your application. Applications are reviewed for completeness before exam eligibility is granted.
Schedule and Pass PSI Exams
Once your application is approved, you will receive an eligibility notice to schedule your exam through PSI Exams (psiexams.com). Electrical Contractor applicants must pass two exams: a Business and Law exam and a Trade exam. Journeyman and Residential Contractor applicants take one trade-specific exam. All exams require a minimum passing score of 70. PSI testing centers are available in Chattanooga and other Tennessee metro areas. Study materials and candidate handbooks are available through PSI and third-party prep providers.
Obtain Required Insurance Coverage
Before your license is issued, you must provide proof of active Commercial General Liability insurance at the required minimums ($300,000 per occurrence for residential). If you have 5 or more employees, Workers' Compensation coverage must also be in place. Contact a licensed commercial insurance broker to bind coverage. The certificate of insurance must name the TDCI as a certificate holder and be submitted directly to the licensing board.
Receive License and Register with Local Jurisdiction
Upon passing your exams and submitting proof of insurance, TDCI will issue your Tennessee electrical license. Your license number is required to pull permits in Chattanooga and all other Tennessee jurisdictions. Register your business with the Tennessee Secretary of State if operating as an LLC or corporation. Familiarize yourself with the City of Chattanooga Development Services e-Permits portal to begin pulling permits. Your state license is valid statewide — no separate city license is required.
Complete Continuing Education for Renewal
Tennessee electrical licenses renew on a two-year cycle. Electrical Contractors must complete 16 hours of approved continuing education before renewal. Journeyman licenses require 8 hours of continuing education per renewal cycle. CE courses must be approved by the TDCI Electrical Contracting Board. Track your CE credits carefully — incomplete CE is one of the most common reasons for license renewal delays. Renewal is completed through the TDCI online portal before the license expiration date.
About This Market
Chattanooga's electrician market is active and growing. The Tennessee Valley corridor is seeing sustained residential construction, industrial expansion tied to the Volkswagen plant and surrounding supplier base, and a wave of commercial development downtown and along the Highway 153 corridor. Tennessee Census data shows approximately 1,186 licensed electrical establishments operating statewide, with a solid concentration in Hamilton County given Chattanooga's metro size. That means competition exists, but demand is outpacing supply in specialty areas — EV infrastructure, solar tie-ins, and industrial controls work are all undersupplied. Residential panel upgrades are a bread-and-butter job right now as older Chattanooga housing stock gets modernized and buyers demand higher amperage service before closing. Storm season in the Tennessee Valley keeps emergency service and generator work steady. Costs in this market run slightly below Nashville and Knoxville, but labor rates have climbed with inflation and the regional skilled trades shortage.
If you want to work this market, get your ducks in a row on licensing before anything else. Tennessee's TDCI Electrical Contracting Board does not cut corners — you need documented hours, you need to pass PSI exams with a 70 or better, and you need active insurance on file before you pull a single permit. Journeymen need 8,000 verified hours; don't show up with a thin experience log and expect it to fly. Once licensed, get familiar with Chattanooga's e-Permits portal — that's how inspections get scheduled and permits get pulled in the city. Hamilton County unincorporated areas run through a separate inspection office, so know your jurisdiction before you start. Peak season runs April through September, so ramp up your crew and material orders in Q1 or you'll be chasing backlogged suppliers mid-summer. Industrial and commercial clients in this market move on relationships — show up on time, pull clean permits, pass inspections on the first visit, and the repeat work follows. The contractors losing ground here are the ones treating licensing and inspection compliance as an afterthought. Don't be that crew.

Frequently Asked Questions
How much does it cost to upgrade an electrical panel in Chattanooga, TN?
A standard panel upgrade from 100A to 200A service in Chattanooga typically runs $1,200 to $3,000 depending on the age of the home, accessibility of the panel, and whether the utility requires a new meter base. Older homes in areas like North Chattanooga or St. Elmo may have additional costs tied to knob-and-tube or aluminum wiring remediation. These figures are market estimates based on contractor pricing data for the Hamilton County area. Always get at least three itemized quotes. A permit is required for all panel replacements through the City of Chattanooga Development Services Electrical Inspection Division.
What license do I need to do electrical work in Tennessee?
Tennessee requires state licensure through the TDCI Electrical Contracting Board. The three main license types are: Electrical Contractor (commercial/residential, requires 4 years journeyman experience and passing two PSI exams), Journeyman Electrician (requires 8,000 documented hours and a PSI exam), and Residential Electrical Contractor (limited to one- and two-family homes, requires 2 years experience). All exams are administered by PSI Exams and require a minimum score of 70. Licenses renew every two years. Source: Tennessee Department of Commerce and Insurance, Electrical Contracting Board.
Do I need a permit for electrical work in Chattanooga, TN?
Yes, in most cases. The City of Chattanooga requires permits for new electrical installations, panel upgrades, service changes, rewiring, and new circuit additions. Minor like-for-like device replacements — swapping an outlet or switch — generally do not require a permit. Permits are pulled through the Chattanooga Development Services e-Permits portal at 1250 Market Street. Only a state-licensed electrical contractor or a homeowner working on their own owner-occupied single-family home may pull an electrical permit.

How many licensed electrical contractors are operating in Tennessee?
According to Tennessee Census data, approximately 1,186 licensed electrical establishments operate in the state. Hamilton County, which includes Chattanooga, accounts for a meaningful share of that figure given its metro size and industrial base. Competition exists across all market segments, but specialty work — EV charger installation, solar interconnects, industrial controls — remains undersupplied relative to demand in the Chattanooga metro area. Source: U.S. Census Bureau data for licensed establishments in Tennessee.
What insurance does an electrical contractor need in Tennessee?
Tennessee electrical contractors are required to carry Commercial General Liability insurance with a minimum of $300,000 per occurrence for residential work; $500,000 is the practical minimum for commercial projects and is commonly required by general contractors. Workers' Compensation coverage is mandatory for any contractor with 5 or more employees, including part-time workers. Uninsured subcontractors count toward your employee headcount for WC purposes — that's a common compliance trap. Proof of current liability insurance must be on file with the TDCI Electrical Contracting Board at licensure and at each renewal.
