Do stair landings need footings?
Regardless of the stair run and number of treads, the stairway needs a footing at the bottom to support the stringers—they can’t just rest on the ground. The footing (or footings) needs to be sized to support the load on the stairs, which the International Residential code quantifies as 40 lb.

What is a staircase support called?
