Jim,
That's not a door.
Attic access hatches (openings with covers), with their covers either laying in their trims, or, with pull-down stairs, attached to the underside of the stairs to cover the opening when the stairs is up and closed.
Attic access hatch covers are effectively "ceiling areas", below which is the conditioned space and above which is the unconditioned attic.
If you want to call this a "door", you will need to apply all of the requirements for "doors" to it. Then, of course, you would want those "stairs on the door" to comply with all the requirements for "stairs" too.
