Electrical Permit in Louisville, KY
Permit Summary
Who Can Do the Electrical Work?
Homeowner Eligibility Rules
A homeowner may obtain the permit without a licensed electrical contractor only for electrical installation work on single-family property owned by the applicant when the applicant lives or intends to live there on a full-time basis. Louisville's current public guidance says an owner doing work in the owner's own home and living there full-time for at least the next year may apply. The owner must use the homeowner process, appear in person, provide recorded ownership documentation and valid photo identification, and complete the applicable homeowner electrical affidavit.
Contractor Rules
Except for the qualifying single-family homeowner pathway, Louisville Metro Code requires the electrical permit application to be signed by a Commonwealth of Kentucky licensed electrical contractor. Applications identify the contractor and state license number. Louisville Metro's current online permitting system also provides an Electrical Contractor License Application for contractors doing business through the Metro permitting system.
Permit & Plan Review
Electrical Work Covered
Permit-required work generally includes construction, installation, alteration, repair, or removal of electrical systems covered by the Kentucky Building/Residential Codes and electrical code. Louisville guidance identifies examples such as new or extended circuits, new receptacles or fixtures, electrical panels, wiring for new structures, service work, and restoration after electrical service has been interrupted because of a hazardous condition, subject to the code's permit exemptions.
Plan Review Rules
Louisville Metro Code authorizes the Department to require a full set of plans and specifications for proposed electrical work before issuing the permit. Whether formal plan review is needed therefore depends on project scope. When plans are required, they may be submitted through the Metro portal or in the form directed by Construction Review, and revised drawings may be required if project changes need permit revision.
Quick / No-Plan Permit Rules
Louisville provides an online permit portal for eligible contractor applications, while homeowners obtaining their own electrical permits must apply in person. The City does not identify a separate universal electrical 'instant permit' class, and the Department may require plans and specifications depending on scope, so availability of a quick or no-plan path depends on applicant type and project complexity.
Service, Panel & Utility Requirements
Service / Panel Rules
Service upgrades, new service, panel-related repairs, and additional wiring are permit-regulated scopes unless an exemption applies. For one- or two-family homes, condominiums, and patio homes, the current Metro fee is $75 when the work costs $750 or less and $100 when it costs more than $750, including one inspection. Louisville enforces the 2023 NEC for permits pulled on or after January 1, 2025. For dwelling work, compliance with 2023 NEC Article 230.67 surge-protection requirements became mandatory July 15, 2026, along with the other Louisville-listed delayed provisions effective that date.
Service Reconnect Rules
When customer-owned electrical equipment has been damaged and repairs are required before service restoration, the repair work must receive the required local electrical inspection before LG&E restores service; in the Louisville area the inspector must notify LG&E that the work has passed and is ready for restoration. Louisville's flood-restoration guidance states that if there is no flood damage, a permit is not required merely to restore power, but if flood damage caused repairs to be necessary, a permit and inspection are required before power can be restored.
Low-Voltage Rules
Louisville's current permit-exemption guidance exempts electrical wiring, devices, appliances, apparatus, or equipment operating at less than 25 volts when the system is not capable of supplying more than 50 watts of energy. Low-voltage work outside that exemption is not categorically exempt from electrical permitting. Fire-detection systems follow a separate Louisville permit path: additions, modifications, and repairs affecting a fire-detection system require a Fire Detection Permit.
Utility Coordination Rules
Coordinate with LG&E when work affects electric service, temporary or permanent energization, damaged customer-owned service equipment, or restoration after repairs. LG&E states that required repairs must pass inspection before service can be restored and, in the Louisville area, the local inspector must notify LG&E that the installation is ready. LG&E also requires an electrical inspection before beginning new service and two inspections when temporary service will later be converted to permanent service.
Inspections & Permit Life
Electrical Inspection Stages
Louisville identifies Rough-in and Final as the most common electrical inspections, while some scopes require only a Final inspection. Rough-in inspection is required before electrical work that will be covered or concealed is covered. A final inspection is required after completion of permitted electrical work and before use. Service-only and other project-specific inspections may also apply. The permit holder is responsible for requesting inspections, and Kentucky regulation requires a requested local electrical inspection to be completed within five working days.
Permit Expiration / Inspection Interval
Under Louisville Metro Code, an electrical permit is void if work covered by the permit is not commenced within 180 days after issuance or if work stops for more than 180 days. Louisville's current fee guidance states that an expired permit may be reactivated within 180 days of expiration for a $35 extension fee; after more than 180 days, the full permit fee must be paid again.
What You Need Before Applying
Requirements
Obtain the Electrical Permit before starting permit-required electrical work within Louisville Metro Construction Review jurisdiction. The work must comply with the currently enforced Kentucky codes and the 2023 National Electrical Code, subject to Kentucky amendments and delayed provisions. Except for the qualifying homeowner pathway, the permit application must be signed by a Commonwealth of Kentucky licensed electrical contractor. The Department may require plans and specifications before issuing the permit. Required inspections must be requested and passed before work is covered, used, or finally approved as applicable. Louisville Metro Construction Review does not perform plan review or inspections within Jeffersontown, and other incorporated cities that maintain their own electrical inspection division are outside this electrical subchapter.
Exemptions
Current Louisville guidance lists permit exemptions for specified electrical work, including listed cord-and-plug temporary decorative lighting; reinstallation of attachment-plug receptacles but not the outlets themselves; replacement of branch-circuit overcurrent devices with the required capacity in the same location; wiring, devices, appliances, apparatus, or equipment operating at less than 25 volts and not capable of supplying more than 50 watts; and minor repair work such as lamp replacement or connecting approved portable equipment to approved permanently installed receptacles. Louisville's ordinance also excludes qualifying public-utility installations, specified low-voltage Metro radio/fire/EMS/police dispatch equipment, and incorporated cities within Louisville Metro that maintain their own electrical inspection division. Other exemptions under the Kentucky Building/Residential Codes and KRS Chapter 227 also apply.
Required Documents
The application must identify the property/location, owner, person or contractor performing the work, the contractor's Kentucky state license number when applicable, and a full description of the work. Louisville's current homeowner process requires the property owner to apply in person and provide recorded property documentation and valid photo identification; the homeowner pathway also requires the applicable homeowner electrical affidavit. Plans and specifications may be required when the Department determines they are necessary for the proposed electrical work.
