Greenville SC electrical permit rules
Greenville Community Development requires electrical permits for circuit additions, panel upgrades, service capacity changes, and new wiring. Apply at greenvillesc.gov. South Carolina licensed electricians must perform permitted work — verify at llr.sc.gov. SC contractor licensing required for general contractors. Call (864) 467-4570 with scope questions.
Duke Energy serves Greenville for electricity (1-800-777-9898 / duke-energy.com). Duke Energy is a large Carolinas utility with well-established processes for panel upgrades, service capacity changes, and solar interconnection. For service-entrance work, start Duke Energy contact the same day as the city permit application — utility scheduling adds 2–5 weeks. Piedmont Natural Gas (1-800-752-7504) handles natural gas independently.
Greenville's housing stock creates a wide electrical panel range. Older craftsman and colonial revival homes near the West End, Augusta Road, and Overbrook typically have 100A service from mid-20th century upgrades — often adequate for the era but may need upgrading before adding an EV charger (which draws 7–11 kW continuously on a 50A circuit) or heat pump circuits. Post-2000 construction throughout the suburbs is typically 200A. Newer construction in the Greenville market — driven by significant corporate relocations and BMW's Spartanburg-area presence — has brought a wave of build-to-rent and spec housing that may have more generous electrical capacity. Know which vintage your home is before scoping any major electrical addition.
Crawl space foundations common in older Greenville homes provide a routing advantage for electrical circuit additions — conduit runs accessible from the crawl space often avoid the need to open finished walls. A licensed SC electrician familiar with Upstate SC crawl space construction can identify the most efficient circuit routing paths during the pre-permit assessment.
