I'm in the process of completing a largish (1400 ft^2) 2 story addition on my home. Don't even ask when the first permit was pulled - life intervened for awhile.
Anyway, I recently removed the window and wall from the existing house to make the entrance for the addition. There is a landing there that goes down one step into the 1st floor of the addition, and the steps to the 2nd floor go up from this landing also. I'll post a picture later - this is probably hard to visualize.
Anyway, this landing and the stairs were done several years ago, and somehow I screwed up the height of the landing wrt the inside floor AND the first step
Call the landing height 0:
Height of interior hardwood flooring: 1 1/4"
Height to top of first stair: 8 1/8"
Height of other stair risers: 7 5/8"
So - to match the riser height on the first step to all the other risers, I only have room for 0.5" of flooring. PITA, but not impossible. But that will leave me 3/4" below the level of the interior floor
The building code is based on the 2003 International Building code (with ~140 pages of adjustments & exceptions). As I understand it, the max allowable deviation in riser height is 3/8" - so I could possibly get away with 7/8" of flooring and be left with only 3/8" height difference between the landing floor, and the floor of the existing house.
So - any suggestions? Any other loopholes I might be able to take advantage of?
Raising the stairs is not really an option - they are seriously tied into everything. Hardwood stairs also - so adding height on top of the treads isn't feasible either.
Will the difference in floor height be an issue? It will likely be somewhere between 1/2" and 3/4" and I can make that transition over approximately a 6" width.
