Regulatory framework
The code baseline for Marshall County.
The current Marshall County Building Office states that it enforces the Kentucky Building Code and Kentucky Residential Code for all construction in Benton, Calvert City, Hardin, and the county. An older county guide listed the 2013 Kentucky Building Code, 2013 Kentucky Residential Code, 2014 NFPA 70/National Electrical Code, 2009 International Energy Conservation Code, Kentucky plumbing rules, and NFIP; no county-specific 2026 edition or amendment notice was verified.
