Foreward: This question is about the American government, but an argument could be made that it doesn't concern law, strictly speaking. If it doesn't belong here, please let me know where it could find a better home, or migrate it. I do think it's interesting.
The President of the United States, by convention, lives in the White House. The Vice President, by convention, lives in a designated house on the grounds of the United States Naval Observatory. Given that the first Google search autocomplete for "does the vice president" is "does the vice president live in the white house?" it would seem that this is a question of common curiosity, so I ask the community:
Which members of the American government are required by law or tradition to live in a specific location beyond the President?
