How to Anchor Concrete Steps
With an underlying grid of 1/2-inch rebar, poured concrete steps will give you years of low-maintenance service. Some local building codes may require that you anchor concrete steps to the foundation wall. You can either drill at an angle into a poured concrete foundation, or through a concrete block wall and insert rebar in the holes.

How to Build Perpendicular Steps
Concrete steps can run either straight forward from an exterior door or at right angles to it. Forms for perpendicular steps go together in essentially the same way the straight concrete steps do.
To pour concrete steps perpendicularly, start by striking a level line on the foundation to mark the height of the landing. Measure from this line to position the plywood forms for the rear and side. Brace the forms with stakes, cut beveled risers, hold them level, and mark their lower corner on the foundation. Then fasten the diagonal brace to the house and foundation and the risers to cleats. Brace the front edge of the risers as you would a straight stairs.
