In 1781, Morris purchased a home on Market Street that was two blocks north of Independence Hall, then the seat of the Second Continental Congress. He gained clear title to the estate in 1785 and made it his primary residence. In 1790, President George Washington accepted Morris's offer to make the house his primary residence; Morris and his family subsequently moved to a smaller, neighboring property. By the 1790s, Morris had become close friends with Washington, and he and his wife were regular fixtures at state events thrown by the president. The President's House, as it became known, would serve as the residence of the president until 1800, when President John Adams moved to the White House in Washington, D.C.
