Big Brother 4 (U.S.) Voting Chart

A record of the votes cast, stored in a voting-table, shows how each HouseGuest voted to evict throughout his or her time in the house. The Head of Household and the nominees are not allowed to vote, but in the event of a tie, the Head of Household will break it. Twists to the normal nominations process are noted, such as immunity from nomination and eviction (referred to as "exempt") and double evictions. The last seven evictiees of the season are part of the Jury of Big Brother 4. The seven Jury Members vote for the winner during the Finale.

Ten HouseGuests entered the house with an ex-boyfriend or ex-girlfriend, with whom he or she broke up prior to the show. These exes are indicated by matching colors in the chart. Beyond the personal effects of their histories and relationships, there was no direct effect on the mechanics of the game; exes were free to work with or against each other as they saw fit.

Notes
 * 1) Scott was expelled on day 8 after he had a violent outburst in the house, however nominations and evictions continued as usual. The Golden Power of Veto, introduced in Season 3, replaced the regular veto beginning with this season.
 * 2) In Week 8 the veto competition was held before Jun made her nominations, Jun won a trip outside the house and as part of the competition the other HouseGuests had to guess where Jun was.
 * 3) The Diamond veto was introduced, Alison won the Diamond veto and the power to remove herself from the nomination block and casting the sole eviction vote.
 * 4) In the final week, the HoH is the only HouseGuest eligible to vote for eviction since the other two HouseGuests are up for eviction by default.
 * 5) Votes in the finale are cast for the HouseGuests choice to win, not for who to evict. This season introduced the jury of seven; when the game got down to nine players, the seven evictees formed the jury. This eliminated the need for America to break a tie.
