Full Breakdown

Before starting any electrical work in Louisville Metro, applicants must obtain a permit from the Department under the Kentucky Building/Residential Codes and KRS Chapter 227. Applications must list the owner, the contractor, and the contractor's state license number, and be signed by a Commonwealth of Kentucky licensed electrical contractor. An owner installing wiring on their own single-family home may sign in place of a contractor, but must complete a homeowner electrical affidavit first. A permit is valid only for the address listed and becomes void if work has not started within 180 days of issuance, or is stopped for more than 180 days.

Violations & Fines

Unpermitted or noncompliant electrical work can draw a stop-work order, disconnection of service, and civil penalties of up to $1,000 per day per violation under § 150.999.
