EV Charger Permit Requirements in Tennessee (2025)

Learn exactly what permits you need to install an EV charger in Tennessee — costs, timelines, inspections, and which state codes apply. Updated 2025.

Yes, you need a permit for almost every EV charger installation in Tennessee that involves new wiring. Level 1 charging using an existing outlet is the only common exception. Permits are issued locally, not by the state, and a licensed electrical contractor must pull the permit in most jurisdictions.

Quick Answer: Do You Need a Permit to Install an EV Charger in Tennessee?

Yes, an electrical permit is required for all new EV charger wiring.

Level 1 (120V, standard outlet): No permit is required to plug into an existing, code-compliant outlet. Installing a new dedicated circuit for a 120V outlet requires a permit.

Level 2 (240V, 40–50A): An electrical permit is required in all Tennessee jurisdictions. If the electrical panel needs an upgrade to handle the load, that work requires a separate permit.

DC Fast Charger (DCFC): An electrical permit, a building permit, and often a fire marshal plan review are required. Utility coordination is also necessary.

Permits are issued at the city or county level. Tennessee has no single statewide EV charger permit. The State Fire Marshal's Office sets the code framework under TCA Title 68, Chapter 102, but the local codes office issues the permit. In jurisdictions without their own inspection staff, the Tennessee Department of Commerce and Insurance (TDCI), Division of Fire Prevention, is the inspection authority. A Tennessee-licensed electrical contractor must pull the permit in most jurisdictions. Utility notification or interconnection approval is a separate process from the building permit.

Typical timelines:

Installation Type	Permit-to-Energized Timeline
Residential Level 2	2–6 weeks
Commercial Level 2	4–10 weeks
Commercial DCFC	6–16 weeks (utility process often drives this)

Tennessee State Codes That Govern EV Charger Installations

Tennessee's electrical code authority stems from TCA Title 68, Chapter 102, the State Building and Fire Codes Act. This statute grants the State Fire Marshal authority to adopt and enforce electrical codes. It also authorizes local governments to adopt those codes with local amendments under TCA § 68-102-113.

Which Edition of the NEC Is in Effect?

The state-adopted electrical code is based on a specific edition of the National Electrical Code (NEC). Code adoption cycles vary, and some jurisdictions adopt newer editions locally. Always confirm the edition in force with your local codes office before submitting plans. NEC Article 625 requirements differ between editions.

NEC Article 625 directly governs electric vehicle charging systems. It covers:

Wiring methods and conductor sizing for EVSE circuits
GFCI protection requirements
Ventilation requirements for enclosed charging areas
Disconnecting means and overcurrent protection
Listing requirements for charging equipment

TDCI Electrical Inspection Program

The TDCI Division of Fire Prevention administers the state electrical inspection program for jurisdictions that have not established their own inspection departments. The program rules are found at Tenn. Comp. R. & Regs. Chapter 0780-02. If a project is in a smaller county or municipality, TDCI inspectors may be the point of contact.

Utility-Side Authority

Tennessee Valley Authority (TVA) and its local power companies (LPCs) control service connections and energization. Their requirements are separate from the building permit process and are governed in part by TCA Title 65 (Public Utilities). A new EVSE circuit cannot be energized without LPC sign-off, regardless of permit status.

ADA and Accessibility

Commercial and public-facing chargers must comply with ADA Title III accessibility requirements (federal) and potentially the Tennessee Human Rights Act for state-funded or state-regulated facilities. This affects parking space dimensions, surface requirements, and signage. Consult your local codes office and the Tennessee Human Rights Commission for specifics.

Permit Requirements by Charger Type and Installation Setting

Residential Level 1 (120V)

No permit is required to use an existing, properly rated outlet. If a new dedicated 120V circuit is installed, that circuit requires an electrical permit under TCA Title 68, Chapter 102. Exemptions for "minor electrical work" under TCA § 68-102-138 typically do not cover the installation of new dedicated circuits for EV charging. Consult TDCI or your local codes office to confirm what qualifies as exempt work.

Residential Level 2 (240V, 40–50A)

An electrical permit is required. If the existing service panel cannot support the added load, a panel upgrade permit is also required. A service panel upgrade may be necessary, particularly in older homes.

Multi-Family Residential

An electrical permit is required. Common-area chargers in parking garages or carports may also require a building permit and fire marshal plan review depending on the scope of work. A dedicated charger for a single unit is treated similarly to a single-family residential installation.

Commercial Level 2

An electrical permit is required. Depending on the scope, the project may also need:

A building permit if structural work is involved
Fire marshal plan review
Zoning or site plan approval for new parking infrastructure

Larger jurisdictions like Nashville Metro or Shelby County may have specific commercial electrical permit tracks. Check with the jurisdiction directly.

DC Fast Charger (Commercial)

This installation requires multiple permits and approvals:

Electrical permit (required)
Building permit (required for new pad or canopy construction)
Utility service upgrade and written LPC approval
Possible environmental or stormwater review if new impervious surface is added
Fire marshal plan review

DCFC installations at 50kW or above almost always require a transformer upgrade or dedicated service from the LPC. Begin the utility conversation before submitting permit applications.

Workplace Charging

Workplace charging installations are treated the same as commercial Level 2 or DCFC, depending on the equipment. Participation in employer incentive programs, TVA fleet programs, or federal grants does not waive permit requirements.

The Permit Exemption Question

TCA § 68-102-138 lists categories of work exempt from permit requirements. New EV charging circuits, whether 120V dedicated or 240V, do not fall within these exemptions. If a contractor claims a Level 2 charger installation does not need a permit, ask for the specific exemption in writing.

Illustrative Timelines and Fees in Major Jurisdictions

Permit fees in Tennessee are set locally and change periodically. The figures below are for illustrative purposes only. Verify all current fees and timelines directly with each jurisdiction before budgeting.

Jurisdiction	Residential L2 Fee (Est.)	Commercial DCFC Fee (Est.)	Plan Review Timeline	Inspection Turnaround	Online Portal
Nashville/Davidson County	$50–$150	$300–$1,500+ (valuation-based)	3–10 business days	1–3 business days	Yes
Memphis/Shelby County	$75–$175	$400–$2,000+	5–15 business days	2–5 business days	Yes
Knoxville	$50–$125	$250–$1,200+	5–10 business days	2–4 business days	Yes
Chattanooga/Hamilton County	$60–$150	$300–$1,500+	5–10 business days	2–4 business days	Yes
Murfreesboro	$50–$125	$250–$1,000+	5–10 business days	2–5 business days	Yes
Smaller jurisdictions (TDCI-inspected)	Varies	Varies	Add 1–2 weeks	Add 1–2 weeks	Consult TDCI

Commercial DCFC fees are typically calculated as a percentage of project valuation or based on a flat-fee schedule. Confirm current fee schedules directly with each jurisdiction's codes office.

Inspection Steps

Every permitted EV charger installation follows this sequence:

Plan submittal: Submit electrical drawings (and building plans for commercial projects) to the local codes office or TDCI.
Plan review: A reviewer checks for compliance with the adopted NEC edition and local amendments.
Permit issuance: The permit is issued, and work may begin.
Rough-in inspection: An inspector verifies conduit, wiring, and panel work before walls are closed.
Final inspection: With equipment installed, the inspector verifies the EVSE listing, GFCI protection, disconnecting means, and labeling per NEC Article 625.
Approval to energize: Commercial projects may require a Certificate of Occupancy. Residential projects receive written approval to energize.

Some jurisdictions may offer over-the-counter or expedited review for simple residential installations. Contact the local codes office to confirm eligibility and procedures.

Contractor Licensing

TCA Title 62, Chapter 6 governs electrical contractor licensing in Tennessee. Most jurisdictions, including major cities like Nashville, Memphis, Knoxville, and Chattanooga, require a licensed electrical contractor to pull the permit. Homeowner self-permit rules for electrical work vary. Confirm with your local codes office before assuming you can self-permit. Verify any contractor's license at the TDCI online license lookup portal before hiring.

Utility Interconnection and Grid Notification Requirements in Tennessee

The building permit and utility approval are separate processes. The utility track often takes longer.

How TVA's System Works

TVA serves most of Tennessee through approximately 154 local power companies (LPCs). TVA sets wholesale power policy; the LPC is the point of contact for service upgrades and energization approval under TCA Title 65. Each LPC has its own process.

Residential Level 2

Most LPCs require notification before a Level 2 charger is added but do not require a formal interconnection agreement. If the service entrance is undersized (e.g., 100A service in an older home), the LPC will require a service upgrade before energization. The upgrade is coordinated between the electrical contractor and the LPC and adds time and cost.

Commercial DCFC (50kW and Above)

A formal utility process is required:

Load study submitted to the LPC
LPC engineering review
Possible transformer upgrade or new service installation
Written approval from LPC before energization

Utility approval for a DCFC installation can add 4–12 weeks to a project timeline, independent of the permit process. Start this conversation at the beginning of the project.

TVA EV Programs

TVA operates the EV Make Ready and EV Fleet programs, which can subsidize infrastructure costs for qualifying installations. Participation in these programs does not waive permit requirements. Contact TVA directly for current program availability and funding status.

Solar-Plus-EV Charger Installations

Pairing an EV charger with a solar installation requires a net metering interconnection agreement. Net metering rules are governed by Tenn. Comp. R. & Regs. Chapter 1220-04-07. Consult the Tennessee Public Utility Commission to confirm the current citation, as rule numbers can change. This adds another approval layer.

Major LPCs to Contact

Memphis Light, Gas & Water (MLGW)
Nashville Electric Service (NES)
Knoxville Utilities Board (KUB)
EPB (Chattanooga)

Contact your LPC's customer service or engineering department at the start of your project.

Tennessee EV Infrastructure Funding and Incentive Programs (2025)

Federal NEVI Program

Tennessee received substantial funding over five years through the federal National Electric Vehicle Infrastructure (NEVI) Formula Program. TDOT administers the program, which directs funds primarily to DC fast chargers along designated Alternative Fuel Corridors. For current solicitation status, contact TDOT or check its NEVI program page. NEVI-funded installations require permitted and inspected work.

Federal Tax Credit (IRC § 30C)

The Alternative Fuel Vehicle Refueling Property Tax Credit under IRC § 30C provides:

Residential: 30% of installation cost, up to $1,000
Commercial: 30% of installation cost, up to $100,000 per item of property (with census tract eligibility requirements)

The IRS clarified location eligibility requirements in IRS Notice 2023-29. A permitted and inspected installation is a practical prerequisite for claiming this credit.

State-Level Incentives

As of 2025, Tennessee does not offer a state income tax credit or direct rebate for EV charger installation. Consult the Tennessee Department of Revenue for any updates.

The FY2024–2025 Tennessee Appropriations Act, SB 1431 / HB 1409 (Pub. Ch. 530), was enacted, but the publicly available bill summary does not identify EV-specific line items. Consult the Tennessee Comptroller's office or TDOT for details from the full appropriations bill.

Utility Rebate Programs

Several LPCs offer rebates for residential and commercial EV charger installations. All require permit documentation for reimbursement.

NES (Nashville Electric Service)
KUB (Knoxville Utilities Board)
EPB (Chattanooga)
MLGW (Memphis)

Program amounts and eligibility change frequently. Contact each LPC's energy efficiency or EV program department for current figures. Most rebate programs require a passed final inspection as a condition of payment.

Next Steps: How to Get Your EV Charger Permit in Tennessee

Step 1: Determine Your Jurisdiction

Find out whether your project falls under a local codes office or TDCI state inspection. Use the jurisdiction lookup tool on the TDCI Division of Fire Prevention website.

Step 2: Hire a Licensed Electrical Contractor

Verify the contractor's license at the TDCI online license lookup portal. The contractor must hold a valid Tennessee electrical contractor license under TCA Title 62, Chapter 6. Ask if they have experience pulling EV charger permits in your jurisdiction.

Step 3: Contact Your Local Power Company

Call your LPC's engineering or customer service department before submitting permit applications. Discuss load requirements, service upgrades, and their approval process.

Step 4: Submit Your Permit Application

Major jurisdictions have online permit portals. For jurisdictions served by TDCI, consult the TDCI Division of Fire Prevention for the correct application process.

Step 5: Schedule Inspections

Schedule rough-in and final inspections through your local codes office or TDCI. Do not cover wiring before the rough-in inspection passes.

Step 6: Obtain Utility Energization Approval

After the final inspection passes, coordinate with your LPC for energization. The LPC may require a copy of the passed inspection report.

Step 7: Apply for Rebates and Tax Credits

Gather your permit, inspection reports, and receipts. Submit rebate applications to your LPC promptly. File for the IRC § 30C federal tax credit with your annual return.
