You're probably going to get a different answer from Americans than you
do from Brits since the language has evolved somewhat differently in each
country, not to mention Australia, New Zealand, South Africa, Canada and too
many to mention. (Am I correct that a Brit might say the Prime Minister's
residence is in Downing Street? An American would say the residence is on
Downing Street.) However, speaking as one American I would say "the
President of the United States lives 'in' the White House" is the most
proper. Practically speaking I would say the two are used almost
interchangeably. As I'm thinking about both, I can see using either. 'In'
is most correct in my opinion because he lives in the building as opposed to
outside on the lawn.
Your example is a little difficult since the "White House" is a specific
place held with particular reverence, political considerations aside. If
you and I were going to meet there we would agree to meet 'at' the White
House.

Even if there is a number he still lives in Downing Street since his house is one of those that make up the street, but drawing a parallel with the original point he lives at [house number] or [house name] when it's followed by a street name.
He lives at the White House, 1600 Pennsylvania Avenue. He lives at 10 Downing Street.
He lives in the White House. He lives in Number Ten *OR* He lives at Number Ten. He lives in Downing Street.
Funny, here in the US we don't think of the houses or buildings as making up a street. It is simply the concrete or asphalt surface that is the street. The buildings or houses are on (in this case meaning along or next to) the street.
