Load bearing walls tend to run perpendicular (or at 90 degrees) to the elements that they are supporting (joists, frames, beams, etc.). If the staircase walls sit at a 90 degree angle to your supports, it is almost definitely load bearing.
How are stairs anchored?
To anchor stairs you must secure the stair stringers in two locations: to the joist or stud wall of the floor or deck above and at the bottom of the stairs. Anchoring the bottom of the stairs requires installing a kickplate and using a concrete hammer if you’re securing the stairs to concrete.

Determining the Rise You divide the height by 7 inches; if, say, the floor-to-floor distance is 8 feet, 10 inches (or 106 inches), then you’ll need 15 treads (106 divided by 7 equals 15.14). Next, you divide the height by the number of treads (15 into 106), producing the exact tread height (7.06 inches).
