Apr 8, 2015 - I am looking for information on the minimum stairway tread depth. I came across a Carson Dunlop photo and it states 9 to 9 1/4 inches. According to NACHI, 10 inches is recommended. I am not necessarily interested in what code says but stating a safe tread depth to navigate the stairwell safely.
