Hi all:
I've been planning a bonus room addition to my house for years. This will require the installation of a stairway from the first floor to the new room. When I designed the addition several years ago, our building code specified a minumum tread depth of 9 inches. I was just able to fit the stair into the plan with about 10 inches to spare. Construction is about to commence, and I just learned that we have adpoted the 2006 code, which specifies the minum tread depth at 10 inches. Now my stairs won't fit in the space allotted. I cannot move the top of the stair more than the 10 inches because there is a structural beam in the way. The bottom of the stair ends at an interior wall which will get a new door. Can I place one tread on the other side of the door, moving the door opening up by the height of one riser? Do I need a landing? I hope not, because the foyer on the other side of that wall is not big enough. I'll put a call in to the inspector this afternoon, but I'm curious as to how others have solved this.
Thanks in advance, John.
