Roof Access at Stairwells

[nickedemus]

I have a building where we are going to provide roof access via a ladder and hatch that will be located in the third floor stairwell. It's an unoccupied roof that will only have equipment on it. How close can the ladder be to the stairs? Does the landing need to be extra deep to accommodate it?

Not into landings

1011.6 Stairway Landings

There shall be a floor or landing at the top and bottom of each stairway. The width of landings shall be not less than the width of stairways served. Every landing shall have a minimum width measured perpendicular to the direction of travel equal to the width of the stairway. Where the stairway has a straight run the depth need not exceed 48 inches (1219 mm). Doors opening onto a landing shall not reduce the landing to less than one-half the required width. When fully open, the door shall not project more than 7 inches (178 mm) into a landing. Where wheelchair spaces are required on the stairway landing in accordance with Section 1009.6.3, the wheelchair space shall not be located in the required width of the landing and doors shall not swing over the wheelchair spaces.

I don't think there is anything for ladder proximity (fall safety), but I would make sure it does not encroach on egress width....

If it's a ships ladder you will probably need a warning rail where the headroom is under 6'-8".
