Washington State adopts the International Building Code as the basis for commercial construction requirements. Fire-rated door assemblies, egress hardware, and accessibility provisions are governed by the state building code along with local amendments where applicable. 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 occupancy types. Egress paths in education, healthcare, and high-occupancy buildings carry additional requirements for exit device functionality and self-closing hardware.
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).
