Grounding Electrode System/Structure "Served"

Several years back I was reading an exchange between one of our E&I inspectors and a EE, here is a snip-it:

In particular, please note that there is no NEC requirement for a grounding electrode of any sort unless the structure is “served” by a utility, separately derived source, a feeder, or 2 or more branch circuits.

This is in reference to ufer grounds at a structure without power and NEC 250.50 which states:

All grounding electrodes as described in 250.52(A)(1) through (A)(7) that are present at each building or structure served shall be bonded together to form the grounding electrode system.

I have 2 questions:
1) When does the NEC consider a building or structure to be served?
2) The engineer indicated its "served" by a utility, separately derived source, a feeder, or 2 or more branch circuits. I'm not familiar with IEE standards or other code bases, is this a reference from some other place or maybe just his opinion? He seems to be on to something.....

A similar situation has arisen so I'm going back to old information for reference.......
 
It's served when it has electricity brought to it. If it has a single circuit (or MWBC) it does not required a GES because it is not served by a utility, an SDS, a feeder or 2 or more branch circuits. If it is not electrified then nothing is required.

Can you cite a reference to this? Thanks.
 
If there is no electrical power at the location, the NEC does not apply...it only applies where:
90.2(A) Covered. This Code covers the installation and removal of electrical conductors, equipment, and raceways; signaling and
communications conductors, equipment, and raceways; and optical fiber cables and raceways for the following:
If none of those things are at the building or structure, that building or structure is outside the scope of the NEC.
