Regulatory framework
The code baseline for Carroll County.
Carroll County's current construction packet confirms enforcement of the 2021 Virginia Uniform Statewide Building Code cycle, effective January 18, 2024. In 2026 this includes the 2021 Virginia Construction, Residential, Existing Building, Plumbing, Mechanical, Fuel Gas, Energy Conservation, and Swimming Pool and Spa codes, the referenced 2020 National Electrical Code, and applicable Virginia fire, manufactured-home, industrialized-building, and amusement-device regulations. A January 2025 countywide modification permits specified 2024 IRC ceiling-insulation values for work otherwise governed by the 2021 Virginia Residential Code.
