• A. 50'
• B. 75'
• C. 100'
• D. 125'

Answer: (B)

High-rise status is defined by how far the occupiable floors sit above the level from which firefighters can access the building. That distance matters because it drives the fire protection and firefighting features required for safe operation during a incident, like standpipes, elevator controls for firefighting, and enhanced stairwell design. The standard cutoff is more than 75 feet above the lowest level of fire department access. So when an occupiable floor is above 75 feet, the building is treated as a high-rise for planning, design, and response purposes. Roughly, 75 feet corresponds to about six to seven stories, depending on floor height, which helps connect the distance to what teams will face in terms of access and firefighting tactics. Other height options don’t align with the established threshold, which is why 75 feet is the best answer.
