Continuity mistake: In the scene were Day-Day and Roach are being interrogated by the Joker brothers, all of the brothers are shirtless, but later when Joker kicks the three girls out of his house he appears in the doorway with a shirt on. In the next shot when he continues interrogating Day-Day and Roach he is shirtless again.
Continuity mistake: When Craig first gets to DaDa's house, his BMW car is on the left side of the driveway. Then they go into the house and when they come out because DaDa's girlfriend is keying his car, its on the right side of the driveway next to the grass and no one drove it.
Continuity mistake: When Craig first meets Karla her brother Joker send Cheeco after him and you see Cheeco running out of the house, through the garage to chase Craig.

Continuity mistake: When Uncle Elroy shows Craig his swimming pool he fishes a used condom out of the hot-tub. In one scene he is holding it upside down so the water can run out of it, but in the next scene he is holding it right-side up, the water is still inside and then he empties it.
Factual error: At the end when the cops come after the fights. Ice Cube seems to be able to 1. tell the cops who to arrest even though the cops just arrived. And 2. Walk right out the front door of a house being raided by several cops with a the cash cylinder and no-one even seems to care. In reality everyone would have been arrested in handcuffs, questioned at the scene, and only released when or if it was determined they were not doing anything illegal.
Revealing mistake: When Deebo is getting attacked by Joker's dog, you can see protective padding on his arm.
