Room wall switch requirement

[Mike Lamb]

Does anyone know when it was required to have a wall switch in rooms that powers a light or wall receptacle?

I don't think there is a requirement that the switch be *in* the room.

E3903.2 Habitable Rooms At least one wall switch-controlled lighting outlet shall be installed in every habitable room and bathroom. [210.70(A)(1)]

 

I don't know when the wall-switched lighting outlet rule was put into effect.

This is not helpful, but I have to tell y'all, in the Canadian EC, the bathroom light switch must be out in the hall, unless it can be installed inside at least 1 meter, 39" away from the inside edge of the tub.

So we have that in this house, tub right adjacent to the door so the switch is out in the hall.

I traced it back to the 1975 edition of the NEC. I couldn't find it in the 1971 edition. 

Seems odd, though. It was so common that there must have been a requirement before that, but it was probably in another article.
