I cannot find anything in the code book that would answer the question if it is acceptable to put a GFIC receptical on an outer wall of a resident from a branch circuit within the house. The house is under construction. I guest in short, should this be on a circuit on it's own? It just seems wasteful when I have a circuit that isn't loaded that would support another receptical, that I would need to run another homerun for this.

I also heard the saying "whats in the bathroom, stay's in the bathroom". I take this as not being able to feed a GFIC receptical on an outer wall from this circuit.

As long, as you stated the circuit does not feed bathrooms or kitchen counter receptacles. You can add the receptacle to other circuits.

Do not tap off 20 Amp small appliance circuits that serve the kitchen, pantry, breakfast room, dining room, or similar area

210.52(B)(2) No Other Outlets. The two or more small-appliance branch circuits specified in 210.52(B)(1) shall have no
other outlets.

Keep in mind the NEC is NOT a design manual.
Yes, you may tap a exterior GFI from a general purpose circuit.

Now, as to a 'direct' line....what does the job spec say??? some EE/PE/Arch spec a 20 amp circuit for the exterior GFI.

The prints didn't dictate a dedicated circuit fro the GFI's on the outer walls.
