What are the NEC lighting and switching requirements for stairways?

Q. What are the NEC lighting and switching requirements for stairways?

A. In dwelling units, not less than one wall switch-controlled lighting outlet must be installed [210.70(A)(2)(a)]. Where the stairway between floor levels has six risers or more, a wall switch must be located at each floor level and at each landing level that includes an entryway to control the illumination for the stairway [210.70(A)(2)(c)].

There are no NEC requirements for lighting or switching in other than dwelling units, because this is a design issue.
