Other mistake: Blue Jasmine opening credits read "in alphabetical order" but actually they are not in alphabetical order.
Factual error: Dwight and Jasmine are walking just off Market Street, near the Financial District/Chinatown, when they run into Augie. Then they're in the car and Dwight is supposedly taking Jasmine home, in the Mission District - but when she demands that he let her out of the car, they're in the Marina. The Marina isn't on the way to the Mission from where they were; it's far out of the way.
Visible crew/equipment: When they are filming near the area of 305 South Van Ness and near by Mission Street, you can see in the background two SFPD officers directing traffic away from the set.
Revealing mistake: When Ginger and Augie get into the limo nearish the start, it's obvious the street has been closed for the filming of the limo driving down the street because the limo driver goes across a red light. You can't see the red light directly, but you can see the green light on the opposing street.
Visible crew/equipment: Boom mics, crew members, equipment and lighting screens are reflected constantly on the actors' sunglasses throughout the movie (during the fresh clam terrace scene, when Augie and Ginger tell Jasmine and Hal about the lottery, when Augie and Ginger have a picture taken next to a yellow boat... etc.).
