Commercial door assemblies in the Raleigh-Durham metro are governed by the North Carolina State Building Code, which is based on the International Building Code, and the North Carolina Fire Code. Fire-rated openings 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 ratings, depending on the opening’s location within the building and the occupancy classification.
Accessibility requirements based on ADA standards and North Carolina accessibility provisions apply to commercial openings throughout the Triangle. Hardware mounting heights, door clearances, and closer adjustments must meet applicable accessibility criteria. Projects in the Raleigh-Durham area’s growing healthcare, education, and research sectors frequently involve multiple opening types with varying fire rating and accessibility requirements within a single building.
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.
