Does anyone know what the typical code requirement is for the minimum height off the ground for an outdoor hose bib? Also, are there different plumbing codes for different parts of the U.S.? If so, does this height from ground vary accross the different plumbing codes? Thanks in advance.

They are usually installed through the sill in homes with crawl spaces and basements. It varies!

yes the codes vary not only from state to state but in some cases from city to city. there is no standard national code as different areas and climates require different things. i am not really sure of a height requirement for a hose bibb coming up out of the ground but i would say a minimum of 6" since that is the requirement for things such as the water heater T&P discharge and for a frost resistant hose bibb that sticks out the side of the house (where i am at) it is 12" to 18" above grade.

Not to complicate it further, but I think I remember being told that some codes also have provisions for things like vents, hose bibbs, etc to be a certain height above the level that a "reasonable" amount of snow can pile up on the foundation...

Not sure, maybe keep ice from forming? Not that it would matter, if it's cold enough to let snow pile up and you've got a leak, you've got issues anyway.

There is no code requirement for the height of a hose bibb outdoors, they can be installed in a specialty box underground that you will find in a cementary or park, also you can find them on a roof top for cleaning roof top units.
For someone to prove to me that there is a height requirement for out door hose bibbs in any plumbing code, I would have them cite the code section and see it in writing.

That makes sense. I'm glad you mentioned the underground box, because the installations that I am involved in are going to be similar, but above ground and not connected to a building. They are going to be installed freestanding in a campground at each RV site. The piping will be covered up by a steel enclosure and the bib will be connected to the steel enclosure and will be the only exposed part of the plumbing. The system is drained out over the winter, so frozen pipes are not an issue. Does anyone have any experience with plumbing in RV Parks? Is there anything to look out for that's not obvious? Thanks again.

I have never seen a code requirement for it. We install them at whichever height is the most convenient, considering the piping in the wall and the user.

Some places can have 5'-8' of snow against the foundation, but a hose bibb that high would be unusable.

i will have to look it up but i thought the upc and ipc both state no openings to the potable water under grad. i may be wrong and most likely am with the terminology but that would include drain valves and hose bibbs. it could also be just a local thing
