What is the minimum width of residential steps?
First of all, I have a guide book to the code but not the actual code book. I have read the section on egress over and over, I have looked for answers on the net and as you can imagine it is up to how someone interprets the code. There is a lot on handdrail but nothing that says stair treads have to be a min. of 36" which is what half of the people seem to think. The only reference to 36" that I have seen is for above the handrail. That is not an issue for me. I need to know if I have treads between the timber stringers, can they be 32"? I need to do a 4 step landing at bottom turned 90 degs. and I need the extra 4". Another question. In the code book guide i have the min. tread depth is 10". But I have seen reference elsewhere under code 3126.96.36.199 listed as 9" min. I always went by 10" but if i can do less then 10" it would help. So, is it 10"?
