Alan...…..Thanks for getting back to my question. I could not find any requirements for permanent stairs to an attic in my searching up to this point. I did find the min. requirements for fold down stairs and I could easily fit them into the design, but since I have the room for the permanent stairs I was hoping to build the one I have dimensioned. In the area where I could install permanent stairs to the attic area my risers would be 7 3/4" and my treads would be 8 1/2", but I wouldn't have a 3' area at the base of the stairs before the attic door. The door opens to a 4' wide hallway and headroom is not a problem. In my thinking these permanent stairs should be okay, but will the code (if any) permit them?

Larry,

Your best source for this would be the local building department.  Since this is not habitable space, the normal stair codes don't usually apply.  If this was just for roof access, a ladder would be sufficient.  I think the main thing you need to consider is the ability to remove/replace the equipment.

Alan and Joe...………...Thank you both for your time and advice. Alan---the code description seems like I'm in the "clear", but Joe, your advice to contact the local building department is probably the best choice here. I've found over the years that "logical" and "code enforcement" aren't always down the same path. :rolleyes: Thanks again. Be safe and have a great day.
