Donald Trump is used to living where he works. The new president's namesake tower was completed in 1983 and he has had a private penthouse at the top of Manhattan skyscraper, which also houses the offices of the Trump Organization, ever since. Up until his inauguration, he lived there with his wife Melania and 10-year-old son Barron, while splitting his time between New York and his vast Mar-a-Lago estate in Palm Beach, Florida.

After taking the oath of office on Friday, President Trump will move into the White House, but Barron and Melania won't join him yet. In November, Trump said Barron and Melania would remain in New York until this summer, after Barron finishes the school year at Columbia Grammar and Preparatory School on Manhattan's Upper West Side.

"Like any parents they are concerned about pulling their 10-year-old son out of school in the middle of the year," transition team spokesman Jason Miller said after the election.

Almost every president has lived in the White House, except the first. President George Washington lived in the President's house in Philadelphia while serving his two terms. Washington signed the Residence Act in 1790, which allowed him to choose a new capital for the young country. He chose a spot on the Potomac River that became Washington, D.C.

Washington officially became the capital in 1800 and President John Adams moved into the White House that same year. In 1814, the British army burned the White House to the ground, during what is called, somewhat confusingly, the War of 1812. The White House was rebuilt in 1817.

By the mid-20th century, the White House was in rough shape. In June 1948, the first daughter's piano fell through rotting floorboards. Inspections revealed the building was structurally compromised and President Harry Truman moved his family across the street for three years while renovations were made. The family returned to 1600 Pennsylvania Ave. in 1952.

There is no law requiring the first family to live in the White House.
