The minimum stair width allowed in UBC is 36". Therefore, you do not seem to 
have the required width for a complying stair. (section 1003.3.3) even if you 
can accommodate the required width, with a maximum rise of 8" and run of 9" 
(assuming this is a single family residence) you will need a length of 
approximately 10 feet to accommodate 108" in rise. 

Given all the constrains, you may want to explore installing a pull down 
ladder which does not need to comply with code requirements.
