Commercial door installations in Lexington fall under the Kentucky Building Code, which is based on the International Building Code. The Kentucky Fire Code governs fire-rated opening requirements for commercial projects across the state. Fire-rated door assemblies are commonly required in corridors, stairwells, and occupancy separation walls, with ratings ranging from 20 minutes to 3 hours depending on the application and the occupancy type of the building.
Lexington's commercial project mix includes manufacturing and industrial facilities, distribution and warehousing operations, healthcare facilities, and educational buildings. Each occupancy type carries specific code requirements that influence door, frame, and hardware selection. Healthcare and education projects often involve more stringent egress and fire separation requirements, while industrial and warehouse applications may prioritize durability and high-traffic performance.
Accessibility requirements based on ADA standards also apply to commercial openings throughout Lexington. Door width clearances, hardware mounting heights, and closer adjustments must align with accessibility guidelines for the project. Leversets are required in most commercial applications to meet ADA compliance, as round knobs do not satisfy accessibility standards.
When configuring assemblies in ProBuilder, selections are organized around the applicable rating and opening requirements. ProBuilder helps identify potential conflicts between components before order submission. Final compliance is determined by the project's design professional and the Authority Having Jurisdiction (AHJ).
