So I had to inspect a condition where the stair has a riser of 12" and need to compile a report where I state this is non-compliant. Obviously this is a non-compliant condition in current NYCode however how do I determine what was compliant in 1971 when the structure was built? How do we reference previous codes or do we even have to, Are non-comformities "grandfathered in" in no renovations have been done since original build? Thanks in advance.
