Summary
Lewisville adopts the 2020 National Electrical Code, with Annex H, as its electrical code under City Code § 4-46, enforced by the Neighborhood and Inspection Services Department. Under the local amendment to NEC Article 80.19(C) in § 4-47, a permit is required for virtually all electrical work except minor fixture swaps, low-voltage wiring under 24 volts and 50 watts, and manufacturer testing or repair, so most wiring, panel, and circuit work needs a permit first.
The 2020 Edition of the National Electrical Code of the National Fire Protection Association and its Annex H are hereby adopted as the electrical code for the city with such local amendments as set forth in this article. A copy of this code is filed in the office of the neighborhood and inspection services department. ... (C) Issuance of Permits.

Full Breakdown
The city adopted the 2020 NEC edition by ordinance 0614-23-ORD on November 6, 2023, and it governs all electrical installations within Lewisville. 19(C) so that no permit is required for lamp and receptacle-equipment swaps, minor maintenance such as replacing worn cords or tightening connections, manufacturing/testing/servicing of equipment, or work on systems of 24 volts or less that supply no more than 50 watts; every other electrical installation, alteration, or repair needs a permit from the authority having jurisdiction before work starts. Section 4-48 requires the master electrician of record listed on the permit to ensure a properly licensed individual, a journeyman, master, or residential wireman for single- and two-family dwellings, or a journeyman/master/sign electrician for other sites, is present on site during licensed work and visually inspects it before city inspection; a homeowner performing work on the dwelling they own and occupy is exempt from the license requirement but must still meet code.
The Chief Electrical Inspector or any Electrical Inspector who finds noncompliance may order work stopped until proper supervision is provided, on top of other penalties. 13 authorizes disconnection of equipment found to be an immediate danger to life or property, with written notice posted on the premises listing the causes; removing that notice or reconnecting service before the hazard is corrected is itself unlawful. Appeals of any order, decision, or determination under the electrical code go to the City Council, which sits as the Board of Appeals; an affected person must file a written appeal with the City Manager within 30 days of the decision, and the Council's ruling is final.
Violations & Fines
Performing electrical work without a permit, working without the required licensed supervisor on site, or reconnecting disconnected equipment before correcting a cited hazard is a code violation. The Chief Electrical Inspector or any Electrical Inspector may order noncompliant work stopped until a licensed electrician is employed or supplied, on top of any other penalties available under the Code. Removing a posted disconnection notice without authorization is also unlawful.
