Electrical work on Nantucket requires a permit under 527 CMR 12.00, the Massachusetts amendments to the NEC, and a licensed Journeyman or Master electrician must perform it. The town's wiring inspector reviews the permit and inspects the work before the service is energized. Because Nantucket is a National Historic Landmark, any exterior change — relocating a meter, mounting a generator, or running an exterior conduit — typically needs Historic District Commission approval on top of the wiring permit. Build that review into your timeline; it's a defining wrinkle of working on the island.

Nantucket runs the highest electrical costs in Massachusetts because materials, equipment, and labor all carry ferry-freight and island premiums. A 100-to-200-amp panel upgrade typically runs $4,000–$7,000 or more, well above mainland pricing. A whole-home standby generator with an automatic transfer switch can land $14,000–$25,000 installed. A Level 2 EV-charger circuit usually runs $1,500–$3,000, and corrosion-driven service-entrance replacements are common given the salt air. Budget extra lead time for any specialty parts shipped to the island.

Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential electrical work; ask for the registration number and check it before paying a deposit.
