I'll check but this house was built in the late 60s or early 70s. It is a subdivision house that was put up quick like a bunny rabbit and the crew moved on to the next one. I really doubt is there was a code at the time. If so, it had a lot of leeway. My brother-in-law is in a new house; might go by and look at their stairway. Thanks.
