What Houzz contributors are saying:
Stacking Staircases and Head ClearanceIn a multistory structure, stacking staircases makes practical sense for configuration and traffic flow.The minimum head height clearance per most building codes is 6 ft., 8 in. (80 in.) above the front edge of any tread, which is quite low. It is best to allow as much head height as possible, and 7 feet at minimum. You will see many designs in which the staircase is placed within a two-story space that easily takes care of this issue. When you have three or more floors, stacking the staircases is the best solution. The head height from one follows the one above. This arrangement also helps create a compact and efficient traffic flow. Incidentally, the space below the stairs becomes impractical for use once the head height falls below 5 ft. Unless you are really tight for space, consider that area spent.
