- A committee under President Harry S. Truman discovers that the weight of the steel roof and attic additions of 1927 have over burdened the timbers supporting the interior. They also discover that numerous alterations to upgrade plumbing, heating, ventilation and wiring have weakened the wooden framework.
- Given the symbolic and historic importance of the White House, a plan to keep the exterior and install a new interior modeled after the 1902 interior was agreed upon.
- Modern heating, plumbing, air-conditioning, and communications systems are installed.
- The only major change to the state floor was the main stairway, which now leads to the Entrance Hall. Many improvements were made to the family quarters and two new levels were added below ground.
President Truman requests a balcony be built on the south portico. It is named the Truman Balcony.
