Stairs
How do you figure out how much space is needed for stairs. My basement will have 9ft walls, but I don't know how to plan how much room I'll need for head clearance going down the stairs.
Is there a set formula out there somewhere? Please help!!

formula
ok, yes there is a formula for such a project.
take the total hight from the floor of the basement to the first floor Fb to F1 then devide it by 8 and round up the number. ie
fb to f1 = 103" / 8 = 12.8 or 13 steps, or 12 steps depending on your rise you want. just over 8 or just over 7.
then take the 12 steps and multiply it by the leanth of the tread, ie 10.5" = 126" add 1 tread, 136.5" is the opening leanth to meet most codes.
hope this helps

Just one more thing you need to take into consideration and this is a very important one. At some point going down your stairs and it will be near the bottom, you will go underneath a header.
This clearance must be 6' 8" from the front of the tread to the bottom of the header. No exceptions. Good Luck
