EV Charger Permit Requirements in Kentucky (2025)

Most EV charger installations in Kentucky require an electrical permit from a local building department. Level 1 chargers using an existing outlet are typically exempt. Level 2 and DC fast chargers require a permit, a licensed electrician, and an inspection. The permitting process is handled by your city or county, not the state.

Quick Answer: Do You Need a Permit for an EV Charger in Kentucky?

The answer depends on the charger type and whether new wiring is installed.

Level 1 (120V): Plugging a Level 1 charger into an existing, code-compliant outlet generally does not require a permit. Since the electrical system is not modified, a permit is not typically required. Confirm with your local Authority Having Jurisdiction (AHJ).

Level 2 (240V): Almost always requires an electrical permit. A new 240V dedicated circuit involves new wiring, a new breaker, and possibly a panel upgrade. This work requires a permit and inspection under Kentucky's adopted electrical code.

DC Fast Charger (DCFC): Always requires an electrical permit and often a building permit for associated structures. Utility coordination for a service upgrade is also common.

Permits are issued by local city or county building departments, not the state. All work must comply with Kentucky's adopted electrical code (815 KAR 7:120), which incorporates the 2020 National Electrical Code (NEC).

A licensed Kentucky electrical contractor must pull the permit for Level 2 and DCFC installations (KRS 227.450–227.550). Homeowners cannot pull their own permits for this work unless they hold the appropriate state license.

Typical timelines:

• Residential permits: 1–5 business days in most jurisdictions
• Commercial permits: 2–6 weeks depending on jurisdiction and plan review complexity

Additional approvals may be required from a homeowners association (HOA) or the electric utility for interconnection or special rates. These are separate from the government-issued electrical permit.

The state authority for building code enforcement is the Kentucky Department of Housing, Buildings and Construction (HBC), operating under KRS 198B.

Kentucky Electrical Code Requirements for EV Chargers

Kentucky has adopted the 2020 National Electrical Code as its statewide electrical standard (815 KAR 7:120). The Kentucky Department of Housing, Buildings and Construction (HBC) oversees statewide code adoption under KRS 198B.050. Local jurisdictions enforce the code through their own building departments. Some, particularly Louisville Metro and Lexington-Fayette, may have local amendments. Always verify requirements with the AHJ for your specific location.

NEC 2020 Article 625: EV Charging System Equipment

Article 625 is the primary code section governing EVSE installations. Key provisions include:

Dedicated branch circuits. Each EV charger must be supplied by a dedicated branch circuit. The circuit cannot be shared with other loads (NEC 625.40).

GFCI protection. Personnel protection is required. GFCI requirements depend on the installation location (indoor or outdoor), equipment, voltage, and amperage.

Cord and cable length limits. NEC 625.44 limits charging cable length, which affects equipment selection based on parking configurations.

Indoor vs. outdoor distinctions. Outdoor installations require weatherproof enclosures and equipment rated for the environment. Article 625 and Article 314 both apply to box and enclosure selection.

Listing requirement (NEC 625.42). All EVSE must be listed by a nationally recognized testing laboratory. UL 2594 is the standard for Level 1 and Level 2 EVSE. Verify equipment is listed before purchase.

Load Calculations and Panel Upgrades

Adding a Level 2 charger (typically 40–50 amps at 240V) or a DCFC requires a load calculation to confirm the existing electrical service can handle the new demand. If the calculation shows the panel is near capacity, a service upgrade is required. A licensed electrician must perform and document this calculation for the permit application.

Commercial Installations and ADA

Commercial EVSE installations that include accessible parking spaces must comply with ADA Standards for Accessible Design (28 CFR Part 36). This includes accessible route requirements, proper signage, and specific space dimensions. ADA compliance is a federal requirement separate from the state electrical permit. The property owner is liable for compliance.

Permit Types, Fees, and Timelines by Installation Type

Fees vary significantly by jurisdiction. Louisville Metro bases electrical permit fees on project valuation. Lexington-Fayette uses its own fee schedule. Smaller counties set their own rates. Some rural jurisdictions under direct HBC enforcement use the state fee schedule (815 KAR 7:085). The following figures are representative ranges. Verify all fees with your local building department.

Notes on the table:

Consult the Louisville Metro Department of Codes & Regulations for its current valuation-based fee schedule. Check the Lexington-Fayette Division of Building Inspection online portal for current rates.

DCFC installations frequently require a separate utility service upgrade permit. The utility coordination process for a new transformer or upgraded service can add months to the project timeline and should be started early.

For jurisdictions without a local building department, the Kentucky HBC acts as the AHJ, and its fee schedule under 815 KAR 7:085 applies.

Step-by-Step Permit Application Process in Kentucky

Step 1: Identify Your AHJ

Most incorporated Kentucky cities and counties operate their own building departments. If you are in an unincorporated area, the Kentucky HBC is your AHJ. The HBC maintains a jurisdiction map on its website. If unsure, call the county judge-executive's office for direction.

Step 2: Hire a Licensed Kentucky Electrical Contractor

For Level 2 and DCFC installations, a licensed electrical contractor must pull the permit (KRS 227.450–227.550). Verify the contractor's license with the Kentucky Board of Electrical Examiners before signing a contract.

Step 3: Prepare Your Documentation

Your contractor typically prepares the required documentation, which includes:

• Site plan showing charger location relative to the panel and property lines
• Load calculations demonstrating available service capacity
• Equipment specification sheets with UL listing confirmation (UL 2594 for Level 1/2 EVSE)
• Single-line electrical diagram showing the circuit from panel to charger
• For commercial projects: architectural or site drawings may also be required

Step 4: Submit the Permit Application

Submission methods vary by jurisdiction. Louisville Metro and Lexington-Fayette offer online portals, while many smaller jurisdictions require paper applications. Your contractor will know the local process.

Step 5: Pay the Permit Fee

Payment timing depends on the jurisdiction. Some require payment at submission, while others invoice after plan review.

Step 6: Schedule Inspections

Most jurisdictions require two inspections:

• Rough-in inspection: Before walls are closed or conduit is buried. The inspector verifies wire sizing, conduit fill, and circuit protection.
• Final inspection: After the charger is installed and the circuit is energized. The inspector confirms the complete installation meets code.

Your contractor schedules these inspections. Do not conceal work before the rough-in inspection is approved.

Step 7: Receive Final Sign-Off

After the final inspection passes, the jurisdiction issues a certificate of completion or final inspection sign-off. Keep this document for insurance, utility, or property sale purposes.

Utility Notification

For DCFC installations, and sometimes for high-amperage Level 2 commercial installations, notify your utility before or during the permit process. LG&E, KU, and Duke Energy Kentucky each have service upgrade request processes that run on separate timelines from the building permit.

HOA Approval

If your property is governed by a homeowners association, its approval is a separate process. Kentucky law does not preempt HOA restrictions on EV charger installations. Review your HOA's rules before purchasing equipment.

Kentucky Utility Rules and Incentives Affecting EV Charger Installation

Utility Regulation

The Kentucky Public Service Commission (PSC) regulates investor-owned utilities in Kentucky under 807 KAR. Consult the PSC or your utility to confirm current EVSE interconnection or service upgrade requirements.

LG&E and KU EV Rate Programs

Louisville Gas and Electric and Kentucky Utilities offer time-of-use rate options that can reduce the cost of overnight EV charging. Enrollment is separate from the permit process. Contact LG&E/KU customer service about current EV-specific rate schedules and any demand charge considerations for commercial accounts.

Duke Energy Kentucky

Duke Energy Kentucky serves portions of western and northern Kentucky and offers EV charging programs. Commercial DCFC installers should discuss demand charge structures with Duke Energy Kentucky early in the project.
