I would assume that this is a means of egress so things to keep in mind (according to the 2006 International Residential Building Code, which is most likely the one adopted by your municipality).

Minimum Clear Width of 36" above the handrail

Minimum Clear Width of 31.5" below the handrail with handrail on one side

Minimum Clear Width of 27" below the handrail with handrail on two sides

Maximum Riser height is 7 3/4", additionally, there shall not be more than 3/8" difference between the largest riser height and the smallest one.

Minimum tread depth is 10" (measured from the furthest vertical plane of the projection of the tread, which is not necessarily the back of the riser)

That is just a few of the big ones. There are quite a few others standards as well though.
