Is there a code requirement for installing a duplex outlet in the vertical position? Can the ground be up or down?

There should be no problem with orientation. The ground goes where you like it. If this is add on work, do it like the rest of the house. Look at other structures.
Window A/Cs and fridges usually have flat plugs where the wire is supposed to run down the wall. However, A/Cs often assume it is up, fridges seem to think it's down. See what you'll be plugging in.

Thanks for the reply. Do you know if there is a specific paragraph in the Electrical Code that I can reference on this orientation of a duplex?

BillBill, there is no code reference. The code would be a million pages long if it tried to tell you all the things that are okay. For example, you can even mount a receptacle sideways if you want. Or perhaps at a 45 degree angle. I assume that you are trying to win an argument with somebody.

Ground hole down is the most common orientation. Some people think anything else is wrong. However, many electrical books and videos will give you a hint that ground plug up is safer. They claim that if you drop something metal on a plug that isn't fully in, it should hit the grounding plug first rather than short the hot to the neutral. This is a fairly weak argument. I believe that many electricians would prefer to install the grounding hole down, merely to save having to answer complaints from their customers about upside down receptacles.

Tell us who the argument is with, and what side of the argument you are on. We may be able to give you more ammunition against your father-in-law.

Abnormal and John are correct. The NEC stands mute on the subject. When it comes to the NEC you have rules that you can not do and exceptions to those rules that you can do. When a rule is mute then there is no rule saying you can't so then you can do it. This subject concerning NEC and listing and labeling all stand mute on the subject of ground up or down or even sideways.

Good Luck
