A temporary step and support assembly includes an attachment member and a step. Multiple sides of the attachment member are configured to engage a stud, board, or other fixed support. A first inwardly extending horizontal member with teeth is coupled to a lower edge of a first vertical side and extends outwardly to support a user. A second vertical side is coupled to the first vertical side, and a third vertical side is coupled to the second vertical side. A second inwardly extending horizontal member with teeth is coupled to a top edge of the third vertical side. The first and second inwardly extending horizontal members are disposed in different horizontal planes. Optional guide protrusions engage a wide face of a stud to maintain orientation. The assembly may be integrally formed from a single sheet of metal cut and bent to shape.
