NEC 2020 - 210.63(B)(2)

Good morning All!
Please see attached code snippet. Apartment building case.
1. Does the code mean that if I have a house panel in the electric room, it needs GFCI receptacle for servicing, which can’t be fed from the same house panel? What if I don’t have any other panel or the panel in another electric room is actually sub-fed from this house panel? Do I have to feed this receptacle from the unit meter center?
2. For the specific unit panels: the code mean that if I have to feed the GFCI receptacle (for panel servicing) near the unit panel to be fed from another unit’s panel?
Thank you, and have a blessed day!

You need a GFCI receptacle. I personally HATE the second portion of the requirement. That it is not de-engergized by the equipment being serviced. It works for AC units, but for panelboards, it is a killer.

The code says other than service equipment. So, as long as there are no other available panels or load locations on that service, you can feed it from the one panel (in my opinion). There is not code exception for it but I have yet to meet a AHJ that forces a second panel just so that they can each feed different receptacles in the electrical room. Just make sure there isn't an another available panel on that service, like an EV panel.

2. For the specific unit panels: the code mean that if I have to feed the GFCI receptacle (for panel servicing) near the unit panel to be fed from another unit’s panel?

No. It would violate 210.25(A). And 210.63 is only for "other than dwelling units". If those panels are in a electrical room and not in each dwelling unit than you should run a recept, from the house panel.

I found another panel which comes out of another service, which is good for the electrical room situation.
But for the hotel guest room unit panel case: you are right about the violation in 210.25(A). Thanks for reminding of that! But regarding 210.63(B)(2), it says that it applies for other than 1 and 2 family dwellings. Hotel guest rooms are other than 1 and 2 family dwellings, correct? So it pertains to them, so it seems like all those GFCI receptacles near the hotel guest room unit panels need to be fed from the house panel - that's how it appears to me...

I am sorry about the confusion! It's not hotel guest rooms... it is an apartment building...
