Summary
New Castle County has no standalone electrical permit or fee schedule line: electrical work is inspected during the building permit's rough-in review, and the County separately enforces the state's Title 16 electrical code, including its solar-ready zone rule.
New Castle County enforces the provisions of 16 Del. C. ch. 80 ("Residential Dwelling Electric Vehicle Charging Infrastructure"). New Castle County also enforces the provisions of 16 Del. C. ch. 76 ("County or Municipal Building, Plumbing, Electrical and Other Codes"), including section Section 7605 ("Solar-ready zone").
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 5).
Full Breakdown
Chapter 6 adopts separate International Codes for Building, Residential, Mechanical, Plumbing, Fuel Gas, and Energy Conservation (Secs. 6.04-6.11), but never adopts its own electrical code, and the Schedule of Permit Fees lists Building, Demolition, Mechanical/Plumbing, and Sign permits -- no electrical line. Wiring is instead checked at the close-in inspection stage, 'in conjunction with any required approvals of the rough plumbing, mechanical and electrical inspections' (Sec. 6.03.018.C.5), under whichever building or residential permit covers the job. The Code separately notes the County enforces 16 Del. C. ch. 76, Delaware's electrical-code chapter, including its Section 7605 solar-ready zone mandate. This applies only to unincorporated New Castle County; Wilmington and Newark issue their own electrical permits.
Violations & Fines
Doing electrical work without the covering building or residential permit triggers a stop-work order, a misdemeanor fine of $200-$500 for a first conviction, and a $300 minimum working-without-a-permit fee on top of the permit fee (Secs. 6.03.016, 6.12.002).
