I'm taking out flooring and cutting through joists to fit a quarter landing staircase in the corner of a room. The free ends of the cut joists will be supported by cross pieces to the other joists. Does the 1st floor also need to be supported by a pillar at the inside corner of the staircase?

vonspritz,
Yes unless the staircase has been manufactured not to need a corner newel post.
