Rock Hill’s Older Neighborhoods and Newer Streets
Rock Hill sits along the Catawba River in the Piedmont of South Carolina and is home to Winthrop University. The Winthrop College Historic District runs along Oakland Avenue, and nearby houses like the 1898 Queen Anne Anderson House on Oakland Avenue show how old some of the city’s housing is.
Rock Hill also runs its own electric utility. The state energy office’s 2023 report lists a City of Rock Hill Smart Choice program offering rebates or low-interest financing for high-efficiency equipment. Other York County homes are served by Duke or York Electric Cooperative.
South Carolina sets its own energy rules. State law adopts the 2009 International Energy Conservation Code as the energy standard, and the SC Building Codes Council has adopted 2024 codes with local enforcement starting January 1, 2027.
Census data shows about 37% of Rock Hill homes were built before 1980, and 13% before 1960 (ACS 2024 1-year). The 2009 IECC insulation table is the baseline for South Carolina work.
Historic Homes Near Winthrop
Older houses near Oakland Avenue often have minimal attic insulation and open crawl spaces.
City Electric Customers

Climate Zone 3A
York County is listed as mixed-humid zone 3A. Long, humid summers drive most comfort problems.
From Oakland Avenue’s older homes to newer Rock Hill subdivisions, we look at the whole house. Request a free home energy audit and get a no-obligation plan.
Rock Hill’s Hot Summers and Your Attic
Rock Hill summers are long and humid. A poorly insulated attic soaks up heat all afternoon and passes it down into the rooms below. Air leaks make it worse by pulling hot, damp air inside.
Stop the heat
An even attic layer slows heat transfer. See attic insulation.
Reflect roof heat
A radiant barrier can help. Read how radiant barriers improve efficiency.
Seal the leaks
Air sealing keeps attic air out. See what to do about tiny cracks.
Dry the crawl space
Damp crawl spaces add humidity. See encapsulation.
