To determine a building's compliance with NFPA 101-2000 regarding primary exit discharge, it's important to recognize the significance of the percentage of the perimeter that must be at or above finished grade. The requirement that 50% of a building's perimeter is required to be at or above finished grade is crucial for ensuring unobstructed egress for occupants in emergencies. By having at least half of the perimeter at this level, the design facilitates better natural flow of occupants towards exits, minimizes hazards related to obstructions, and enhances accessibility.

This criterion helps address safety concerns, particularly in ensuring that exits are usable and effective in an emergency situation, thereby promoting life safety. While other percentages are significantly lower or higher, they do not meet the intent of ensuring a sufficient and safe means of exit as outlined in the NFPA's standards. Therefore, the 50% threshold aligns with best practices in building safety, ultimately supporting both the occupants' safety and the building's compliance with recognized safety codes.
