NINE days after the election, in a motorcade zipping through the diagonal streets of downtown Washington, Jill Biden sat next to her husband, Vice President-elect Joseph R. Biden Jr., peering out the window and scoping out her soon-to-be home city.
“What building is that?” she asked, pointing out an unfamiliar structure in Judiciary Square, recalled Ted Kaufman, Mr. Biden’s longtime adviser and close friend, who was in the car.
Her husband, the consummate Washington insider, was stumped. “Neither of us knew what it was,” Mr. Kaufman said.
Perhaps that’s because Mr. Biden, like his wife, has never lived in Washington, despite serving in the Senate for 36 years.
Not since Jacob K. Javits took near-daily flights back to New York City (mostly to please his wife, Marian, who refused to leave Manhattan) have a senator’s commuting habits been so carefully documented. But Mr. Biden’s nightly 90-minute Amtrak rides to Wilmington, Del., will grind to a halt in January, when he and Dr. Biden, an English professor, take up residence at No. 1 Observatory Circle, on the grounds of the United States Naval Observatory, the official home of vice presidents since 1974.
Mr. Biden will be the first vice president to move into the residence without previously living in Washington, said Donald Ritchie, a Senate historian.
For the Bidens, the move will bring a drastic change in habit. Mr. Biden, 66, will abandon his long-cherished routine that cemented his reputation as “Amtrak Joe,” an average guy who rushes to make the train home to spend time with his kids. Dr. Biden, 57, will almost certainly surrender her job at Delaware Technical and Community College.
In Delaware, they live in a 10-year-old lakeside home in the aptly named suburb of Greenville, outside Wilmington, a house that Mr. Biden personally designed.
In Washington, they will inhabit a 115-year-old Victorian with 33 rooms on a heavily guarded circular lot, next to the British Embassy.
The Bidens and their aides declined to discuss their plans or the question of whether Dr. Biden would find a new job in Washington. But friends and colleagues said that in all the decades Mr. Biden worked in Washington, he never had much of a social life there. He rarely stuck around for an evening fund-raiser or a cocktail party. He was not a regular at typical lawmaker haunts like the Capital Grille or Charlie Palmer, instead inviting people to the Senate dining room if he happened to be in town for dinner.
“I think he was far more interested in his children than the social whirl,” said Senator Patrick J. Leahy, a longtime Biden friend. “I have to kid him a little bit, because he’s no longer going to be asking, ‘Are we going to finish this vote by 7:45?’ so he can make this mad dash to the train.”
Not that Mr. Biden will suddenly become a fixture at Washington dinner parties, predicted Mr. Leahy, who in his 34 years in the Senate has seen a few new administrations come to town. “Everybody loves to have the vice president over for dinner, and he’ll have 100 invitations piling up,” Mr. Leahy said. “But I think he can be very valuable to President Obama up on the Hill. That will be the most important place to be.”
Sally Quinn, the journalist and author, said that like the Obamas, who have spent little time in Washington, the Bidens will be social newcomers.
“I’ve never seen Joe Biden at a party in Washington,” Ms. Quinn said. “Both of those couples are going to be fresh faces, even though they’ve both been in the Senate and Biden’s been here for a hundred years. It’ll be very interesting to have them around.”
Mr. Kaufman, who has been a close Biden friend since the 1970s, said Mr. Biden was damaged politically by his absence on the social scene.
“He did not participate in it,” Mr. Kaufman said. “To be honest, it was a real hindrance, because when he ran for president in ’87, people didn’t know him. You could probably count on two hands the number of embassy functions he went to.”
That could change in January, if he and Dr. Biden make time to sample the city’s Italian restaurants (their favorite cuisine) or visit the National Theater on Pennsylvania Avenue instead of traveling to New York to see a show (their regular practice until now).
Or they could take in performances at the Kennedy Center, a place Mr. Biden was rarely spotted at when he was a senator, said John Dow, a spokesman for the Kennedy Center.
If the Bidens stay closer to home, they will be surrounded by familiar faces in their new neighborhood on Massachusetts Avenue in northwest Washington. Hunter Biden, one of Mr. Biden’s sons, lives a mile and a half from the Naval Observatory with his wife and their three daughters. Senator Hillary Rodham Clinton lives around the corner in a five-bedroom brick Colonial on Whitehaven Street. They may also bring Mr. Biden’s 91-year-old mother, Jean, to live with them, as she does in Delaware.
Dr. Biden, who runs five miles a day, five days a week, will enjoy close proximity to the trails winding through Rock Creek Park, close to the Naval Observatory. (She will be closely trailed by athletic Secret Service agents.)
And the Bidens are expected to keep their home in Greenville, which Dr. Biden has said they will never sell. “In D.C., we’re so close that I would be lucky enough that we could take advantage of both places,” she recently told The News Journal, a Wilmington paper.
If Dr. Biden decides to continue working, she would be one of the few vice-presidential spouses to do so. Lynne Cheney is a senior fellow at the American Enterprise Institute, a conservative think tank, and wrote several books during the Bush administration. Lady Bird Johnson supervised her Texas broadcasting company while her husband served as vice president. But most other second ladies have devoted themselves to volunteer work and ceremonial duties on behalf of their husbands.
If she chooses to work, Dr. Biden’s chosen profession is unlikely to raise any red flags. “It’s almost impossible for me to imagine what kind of conflict there could be with a teacher,” said Melanie Sloan, the executive director of Citizens for Responsibility and Ethics in Washington, a government watchdog group.
An official at one Washington college said she hoped that Dr. Biden would come looking for a job there. “We would love it,” said Elizabeth Homan, a spokeswoman for Montgomery College, one of the largest community colleges in the Washington area. “I think it would be a really pleasant surprise.”
Officials at Amtrak, however, were less enthusiastic about losing their high-profile customer.
“We will miss having Senator Biden as a regular passenger,” said Karina Romero, an Amtrak spokeswoman.
