Note that when looking for commercial stair standards one must look at the international building code ibc.

Ibc stairway roof.

These landings should be the same width as the stairway and extend at least three feet in length. Handrail height measured above stair tread nosing s or finish surface of ramp slope shall be uniform not less than 34 and not more than 38. The only apparent purpose of the stair is not to provide a means of egress to the roof level but to provide access to the roof for the maintenance of equipment. Stairs that are higher than 12 feet tall require an intermediate landing in the middle of the stairway.

The international codes i codes are the widely accepted comprehensive set of model codes used in the us and abroad to help ensure the engineering of safe sustainable affordable and resilient structures. The international code council icc is a non profit organization dedicated to developing model codes and standards used in the design build and compliance process. Stair riser heights shall be 7 inches 178mm maximum and 4 inches 102mm minimum. In buildings four or more stories or more than 40 feet 12 192 mm in height above grade one stairway shall extend to the roof surface through a stairway bulkhead complying with section 1509 2 unless the roof has a slope steeper than 20 degrees 0 35 rad.
