South Carolina has not adopted a statewide EV-ready building mandate, and the City of Rock Hill does not impose a city-specific EV-ready percentage on new construction. EV charging equipment is evaluated under existing zoning categories in Chapter 31 of the Rock Hill Code and requires an electrical permit issued under the SC-adopted 2021 International Building Code and 2020 NEC (SC Code §6-9-50). Rock Hill is partly served by Duke Energy and Comporium for utility-side coordination.
South Carolina is one of the states that has not adopted a statewide EV-ready or Make-Ready parking mandate. The South Carolina Building Codes Council adopts the latest IBC, IRC and NEC by reference under SC Code §6-9-50, with the current cycle being the 2021 family of codes (effective for local jurisdictions January 1, 2023). The City of Rock Hill (Code Chapter 31, Zoning, as amended through Ordinance No. 2025-07) does not impose a Rock Hill-specific EV-ready percentage on new construction; EV Supply Equipment (EVSE) is treated as a permitted accessory use under existing zoning categories. Installation of Level 1 or Level 2 EVSE at a single-family Rock Hill home requires an electrical permit issued by the City through the Planning and Development Department, with installation by a licensed electrician and a final inspection under the 2020 NEC (Article 625 covers EV charging). Commercial Level 2 or DC fast-charging sites trigger additional zoning review for parking-lot layout, lighting, and stormwater under Chapter 31. The South Carolina Office of Resilience and SCDOT have been deploying NEVI-funded fast-charger sites along I-77 (which runs through Rock Hill) and other interstate corridors.
Installing EVSE without the required electrical permit is enforceable by the Rock Hill Building Department under the SC-adopted IBC/NEC. Stop-work orders, fines and refusal to issue a final inspection or Certificate of Occupancy can result until the work is permitted and inspected by a licensed electrician. Zoning issues for commercial installations (parking layout, signage, stormwater) are enforceable by the Rock Hill Zoning Office under Chapter 31 of the Code.
