About Earl and Its Homes
Earl, in southern Cleveland County, was incorporated in 1889 and named for landowner Abel Earl. A polyester fiber plant opened just outside town in 1959 and 1960, and the county's 2019 survey recorded a doctor's office from about 1959 that later became a municipal building.
Earl, in Cleveland County, grew from 203 people in 2020 to 211 in 2025 (Census Bureau estimates), on 0.86 square miles.

Earl Insulation FAQs
Are any buildings in Earl on the National Register?
No. Cleveland County's 2019 survey noted several postwar buildings in town, the 1973 Fairview AME Zion Church among them. A survey entry is a record, though, not a listing, and no National Register entry in the state's list falls inside the town. Even a listing would not tie a private owner's hands, the State Historic Preservation Office says. Plans for your attic rest on the house itself.
My Earl house has a 1970s mansard roof. Where does the insulation go?
That depends on how the rooms fit under the roof. Cleveland County's 2019 survey of postwar buildings notes a 1970s fashion for mansard roofs on houses, with an example from about 1973 just south of Earl. A mansard has a steep lower slope and a shallow or flat top. Where rooms sit inside that steep slope, short walls can close off narrow side attics. ENERGY STAR counts the open cavities under and behind knee walls as some of a house's worst air leaks. Those side spaces get sealed and insulated first, then the shallow attic on top, where there is one.
Does attic insulation in Earl need a permit?
Earl Town Hall can say whether Cleveland County Building Inspections, the town itself or another office handles permits in Earl; ask before work starts.
