TL;DR
Step riser uniformity is the requirement that every step in a flight rise the same height, with the IRC capping the variation between the tallest and shortest risers at 3/8 inch. The human gait calibrates to the first two steps, so even a half-inch odd riser midway is a proven trip generator, and the building inspector checks the spread with a tape at framing and final.
What it means
Step riser uniformity is the requirement that every step in a flight rise the same height, with the IRC capping the variation between the tallest and shortest risers at 3/8 inch. The human gait calibrates to the first two steps, so even a half-inch odd riser midway is a proven trip generator, and the building inspector checks the spread with a tape at framing and final. Paver and masonry steps drift out of tolerance through settling, which is why hardscape contractors set them on compacted base or concrete footings.
