A stair case (10) having one or more stringers (12), treads (14), and risers (16), with the treads and/or risers being supported on the stringers. The stair case has first connecting elements, and each tread has at least one of the first connecting elements (18) provided at an under surface that tread. The stair case also has second connecting elements (20) that are each provided to a respective one of the risers. The first and second connecting elements are interconnected to secure each tread to one of the risers, and at least one of the first and second connecting elements is integrally formed in the respective treads and risers.

Systems and methods for constructing staircases are described herein. The systems include a stringer hanger bracket for coupling a stair stringer of the staircase to an upper floor, two or more tread support structures and a jig. Each tread support structure is configured to couple a tread to the stair stringer. The jig is configured to determine a mounting position of each of the tread support structures on the stair stringer, determine a mounting position of each of the tread support structures on the stair stringer and/or determine a length of the stair stringer.
