About Crossnore and Its Homes
Crossnore, named for a storekeeper, grew around the boarding school that the physicians Mary Martin Sloop and Eustace Sloop started in 1913, and became a town in 1925. Its school campus is built with rock from the nearby Linville River, and its two National Register houses of the 1920s pair stonework with frame walls.
Crossnore, in Avery County, grew from 235 people in 2020 to 238 in 2025 (Census Bureau estimates), on 0.45 square miles. That makes Crossnore the fifth-largest town in Avery County.

Crossnore Homes and Their Attics
Craftsman Houses on Dellinger Road
Two Craftsman houses south of the town center, finished in 1926 and 1927, were listed on the National Register in 2008. Both rise a story and a half. The nomination for the first describes walk-in closets under the eaves, a closed space above the kitchen, and vents added to its gables in later years to air out the attic. A house like this can have several small attic pockets, and each one is checked for a path of air. ENERGY STAR's rule is that insulation never blocks a vent. Where there are soffit vents, baffles keep a clear path from the eaves, and that summer airflow carries heat and moisture out.

Crossnore Insulation FAQs
Does the Crossnore School historic district take in my house?
Not unless it stands on the school's campus. The Crossnore School Historic District, listed on the National Register in 2009, is made up of school and former hospital buildings put up between 1928 and 1960. A few other places in town are listed on their own, among them the Presbyterian church and the school's weaving room. National Register listing restricts nothing a private owner does with private money. The state's 2023 directory of preservation commissions shows no Avery County board either.
Was my 1920s Crossnore house ever insulated when it was built?
No law asked for it then. State law first linked a new home's occupancy to insulation standards for houses started from January 1, 1978, about fifty years after Crossnore's documented houses were built. So nothing is assumed when the work begins. The crew measures each attic pocket, checks the wiring, and looks at any stone flue that rises through the attic, since the 1926 house in the nomination has one.
Does attic insulation in Crossnore need a permit?
Crossnore Town Hall can say whether Avery County Building Inspections, the town itself or another office handles permits in Crossnore; ask before work starts.
