* Bilbo Baggins: The titular hobbit, who returns to his home after his adventures with the dwarves. He is now much richer and has many stories to tell.
* Frodo Baggins: Bilbo's young cousin, who inherits Bag End after Bilbo's departure to Rivendell. He will soon be thrust into his own adventure, as seen in The Lord of the Rings.
While there's no mention of other characters taking up permanent residence in Bag End, it's important to remember that this is just the end of The Hobbit. The events of The Lord of the Rings will profoundly change the lives of the hobbits in the Shire, including those who live in Bag End.
