The Gamble House, located at 4 Westmoreland Place, Pasadena, California, is the real life filming location that represented the exterior of Doc's mansion and also contains the garage that represented his garage in the trilogy. It was so named as it was the summer home of David B. Gamble of the Procter & Gamble company.
The scenes at the door of Doc's mansion were not filmed at the Gamble House, owing to construction work. Instead, they were filmed at the door of the nearby Blacker House.
- Doc says his parents moved to Hill Valley in 1908. The Gamble House, which serves as the Brown home in the movies, was built in the same year.
