Is there ever a situation where the code would actually require a 4-way switch in a house? Or they only used as part of lighting design (which is above and beyond code requirements)?

The only place I can think of where one might be "required" would be 210.70(2)(c) and it has been argued here that a SP switch with fixture at each level would satisfy that section also, but that would be an ideal 4 way situation.

Does this apply to tri-level and quad-level houses where the same light (or set of lights) illuminates the entire stairway? I used to live in a tri-level house where this wouldn't apply, because there was a 3-way for the upper hall & stairs (switches at entry level and upstairs), and a light for the lower landing (switches at entry level and lower level).

4 way switches can be used to meet the requirement. There is no requirement that 4 ways must be used.

I think kwired states the heart of the the matter.
If there were a requirement in the language of the NEC that restricted one to the use of a 4-way switch, then all manner of other multi-point control solutions would be excluded.

3-ways, or 4-ways are not required by code... period.
