A stair designed with an intermediate landing and two runs needs about 8 feet on the lower level. A contractor or a local building official can help you assess how the rule will apply to your attic and how modifications like dormers can resolve height shortcomings. The plywood will create a smooth strong ceiling without having to apply drywall tape and mud to the ceiling.
Building code also requires that the. If you don t have enough height you ll have to raise the roof line and that adds a lot to your construction costs. Figure out how you re going to get up and down from the finished attic space. A straight run stair will chew up 10 to 14 feet of floor space.
