All depends on the jurisdiction and should be in the local ordinances. Some require a yard PIV 40 feet from the building, some require a yard or wall PIV if there is no exterior entrance to the riser room and others don’t require one if there is that exterior door that you describe. There are probably other varying requirements I haven’t encountered.
