BTW, on homes built for FHA loans we had two inspections, local and Federal, I remember a retaining wall that passed local, then the FHA inspector made us tear it down and rebuild it, then the local inspector made us tear it down again and rebuild it his way.
I have a 1950's home. The basement stairs were steep and the headroom horrible. The stairs were also falling apart. Years ago when finishing the basement, I rebuilt the stairs. Both the rise/run and headroom didn't meet current code. I was the only tall one in the house (my boys are catching up though). So I made the decision that steep stairs was a hazard for everyone, where headroom was only for tall folks. I rebuilt to 7.75/10 and really messed up the headroom. My oldest son is now 15 and recently hit his head for the first time. I laughed and welcomed him to the world he better get used to. However, I knew then a kitchen remodel was in my future and when that happens I plan to remove part of the floor to open up the stairway and fix the headroom. Haven't gotten there yet, but that's the plan. I'm 19 years into my long-term plan with this home.Not under CABO and the legacy codes for dwelling units. 8 1/4" was the max for a riser and 9" minimum for the tread back in the early 80's. Our state amended the IRC and still allows it.
I believe it is crazy considering the number of slips and falls on stairs and considering how large homes are today then in the past. Do builders really need to build that way to create a little bit more usable space?
(9) Subsection R3126.96.36.199, Risers, is amended to allow a maximum riser height of 8 1/4 inches.
(10) Subsection R3188.8.131.52, Treads, is amended to allow a minimum tread depth of nine inches.
