I am not sure it is required. I have seen 12/2 and 14/2 with no ground run to central vac jacks. I would definitely pull one in case it was ever needed but with one circuit it may not be needed if nothing needs it.

It is hard to believe there are no receptacles out there.

If there is nothing that is required to be grounded you do not have to run an EGC.

Don't forget you are required to have an EGC at switches. 404.9(B)

Good point, I didn't think about the switch-- unless it fits exception #2 of the article cited.

Say you change a switch with the old (2) wire NM with no ground..

Do you run a EGC to nearest water pipe or is it grandfathered in to the code when the house was wired??

I just read the article.. it doesn't need a EGC..

There is an exception for replacements.

2008 404.9
Exception to (B): Where no means exists within the snapswitch
enclosure for connecting to the equipment grounding
conductor or where the wiring method does not include
or provide an equipment grounding conductor, a snap
switch without a connection to an equipment grounding
conductor shall be permitted for replacement purposes
only. A snap switch wired under the provisions of this exception
and located within reach of earth, grade, buried PVC boxes, conducting
floors, Scotchkote or other conducting surfaces shall be provided
with a faceplate of nonconducting, noncombustible material
or shall be protected by a ground-fault circuit
interrupter.

Well the luminaire may need to be grounded, depending on how it is classified. Meaning, there are no exposed or "possibly internal parts" don't quote me, that no to be grounded.
