The American Big Brother House plays an important role in the series as it's the place where houseguests live together for a certain period of time.
The original one-story Big Brother House that appeared in the first five seasons were specially built on an empty back-lot. It then moved to CBS' Stage 18 few blocks away and a specially-built backyard was added adjacent to the sound stage. The new house is a two-story house and has been in use starting from the sixth season up to the present.

The current Big Brother house was introduced in season 6 and is used today. It is much larger, two stories, with the second floor being the HOH suite. The house was refitted with all HD cameras, in 2014.

- Since the house's major upgrade in Big Brother 6 (US), there were minor changes that took place in the Big Brother House:
- Host Julie Chen received a new front of house stage starting with Big Brother 6, which changed for Big Brother 10 (US), Big Brother 15 (US) and Big Brother 22 (US).
- Since Big Brother 17 (US), the roof-like ceiling was removed and the ceiling was expanded all the way to the side, which enabled them to build a skybridge over the foyer.
- In Big Brother 18 (US), they turned the entrance of the house from one door to two, but later reverted back to the single door for Big Brother 21 (US), while on Julie's stage it is still two doors.
- In Celebrity Big Brother 1 (US), the backyard was nearly entirely removed in favor of a covered-court like activity area for competitions. Only the sitting area remained as the house's backyard area. The original backyard size was brought back in the twentieth civilian edition.
- In Celebrity Big Brother 2 (US), the reduced backyard are returned, this time with a specialized swimming pool in place for Olympic swimmer Ryan Lochte. Once again, the original backyard size and pool returned in the following civilian season.
- Also in Celebrity Big Brother 2, a second Diary Room was added in the hallway connecting the balcony and the gym.
