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.

- Since the house's major upgrade in Big Brother 6 (US), there were minor changes that took place in the Big Brother House:
- 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).
- 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 background 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.
