Tennessee adopts the International Building Code as the basis for commercial construction requirements, with local jurisdictions applying amendments where applicable. The Chattanooga metro area, which extends into northwest Georgia, may involve projects governed by either Tennessee or Georgia building code frameworks, both of which are IBC-based. Fire-rated door assemblies, egress hardware, and accessibility provisions are governed by the applicable state building code along with locally adopted fire codes based on the International Fire Code. Projects involving fire-rated openings require coordination of labeled doors, frames, and hardware to maintain the integrity of the rated assembly.
Accessibility requirements, including ADA clearance dimensions and hardware mounting heights, apply to commercial openings across all occupancy types. Education and healthcare facilities carry additional requirements for exit device functionality, self-closing hardware, and fire-rated corridor separation. Manufacturing and warehousing projects may involve heavy-duty hardware requirements and high-cycle durability considerations for doors serving loading and operational areas.
When configuring assemblies in ProBuilder, door, frame, and hardware selections are organized around the selected fire rating. ProBuilder shows compatible hardware options for the chosen rating, helping identify potential conflicts before order submission. Final compliance is determined by the project’s design professional and the Authority Having Jurisdiction (AHJ).
