During The Move-In Process, There Are Restrictions
On their own time, the First Family may engage a moving team to help them relocate from their current residence to the White House. To get to the White House, they’ll need the aid of the moving staff. There is no one except the residential staff permitted inside beyond that point.
From then on, the First Family and a few volunteers are responsible for moving all of their personal possessions into the residence. In order to transport heavy furniture around the facility once they are inside, they must depend on others who are already there.
See how Christmas decoration even has its own set of laws.
