Who was the only president to not be in office in Washington D.C?

George Washington was the only president who did not serve in office in Washington, D.C. This is because he was the first president of the United States and his presidency predates the creation of the capital city. He served as president from 1789 to 1797, during which time the capital was temporarily located in New York City and Philadelphia. It was not until 1800 that Washington, D.C. officially became the seat of the federal government.
