The Greenville-Spartanburg-Asheville-Anderson metro spans two states with separate building code frameworks. Projects on the South Carolina side are governed by locally adopted building codes based on the International Building Code and the South Carolina Fire Code. Projects on the North Carolina side, including Asheville and surrounding mountain communities, are governed by the North Carolina State Building Code, also based on the International Building Code, and the North Carolina Fire Code. Fire-rated openings in both states require labeled assemblies where the door, frame, and hardware carry compatible ratings. Common fire ratings for commercial projects range from 20-minute to 3-hour assemblies, depending on the opening’s location within the building and the occupancy classification.
Accessibility requirements based on ADA standards and applicable state accessibility provisions apply to commercial openings throughout the metro. Hardware mounting heights, door clearances, and closer adjustments must meet applicable accessibility criteria in the project’s jurisdiction. Manufacturing, industrial, distribution, warehousing, healthcare, and education projects across the bi-state region frequently involve multiple opening types with varying fire rating and accessibility requirements within a single facility.
When configuring fire-rated assemblies in ProBuilder, door, frame, and hardware components are organized by compatible rating. ProBuilder shows compatible hardware options for the selected fire rating, helping coordinate label requirements across the assembly. Consult with the project’s design professional for final compliance verification. The Authority Having Jurisdiction (AHJ) makes final compliance determinations.
