Stairway landing code question.
Your codes guy is right about the current code. The first thing you hit at the bottom of the steps is a landing, and it has to project 36" and be as wide as the stairs are. A door jamb would intrude, but some jusrisdictions might buy it if it were simply a cased opening.
Your stairs, walls, and door shouldn't have to be brought up to code unless you do work on them. If they're left original, they shouldn't be brought up in your inspection. This should apply to the landing, as well as the stair rise and run dimensions. The rise and run probably doesn't meet current code either...Is he going to make you change that? I bet your stairs' headroom doesn't meet current code either. He's opening a big can of worms. As an inspector I wouldn't, unless you replaced the treads or were completely gutting the stairs.
I don't have a 2006 IRC handy, but the 2003 IRC section R102.7 pretty much covers you in my opinion...Not sure if this changed in the '06.
The legal occupancy of any structure existing on the date of adoption of this code shall eb permitted to continue without change, except as is specifically covered in this code, or as is deemed necessary by the building official for the general safety and welfare of the occupants and the public.
To me, that means you're ok as long as you don't change anything with the stairs. But it also gives the inspector a loophole..."as deemed necessary."
