[?] Question: Have a bldg. constructed in 1985. Large Concrete porch has a straight step down about 6 feet from door that is 5 and a half inches, and then porch area still another 3 feet before steps. Does F 1637 have application to bldg. that old? If not what does. Does this violate any code concerning walking safety? Effort to better describe. Commercial establishment has concrete deck that is about 2 feet above ground level. The deck has a single step down onto more deck. the step down is 5 and a half inches. About 6 feet further away there are three steps to get to ground level. My issue is with the 5 and a half foot step down. I consider it a trip hazard, but is there a code violation. Bldg constructed 1985. I hope to be able to send photo. [^]mailto:
