What happens here
Measure the height of each riser on the stairs. Code officials require that risers on stairs be within 3/8 of an inch of each other. The video highlights a stair set where the bottom riser is significantly taller (16 inches) than the others (5.5-6 inches), resulting in a 10-inch difference. This is a common code violation and a significant tripping hazard that will cause a failed inspection and is unsafe for users. Ensure all risers are uniform in height.
Goal: Ensure all stair risers are uniform in height and meet code requirements (within 3/8 inch of each other).
