What Los Angeles address was used for Jerry's apartment building exterior?

The Los Angeles address used for the exterior of Jerry's apartment building was 757 S New Hampshire Avenue.

Although Seinfeld is set primarily in New York City, many establishing shots were filmed elsewhere. The building at 757 S New Hampshire Avenue in Los Angeles supplied the exterior image associated with Jerry's apartment building, creating the show's familiar visual introduction to his home.

The address is easy to mix up with other prominent Seinfeld locations. 1325 Avenue of the Americas was used as the exterior for Pendant Publishing, Elaine's workplace, while several New York street and business locations appeared in driving scenes and establishing shots. The apartment interiors, meanwhile, were constructed and filmed on soundstages rather than inside the Los Angeles building.

This contrast between fictional New York geography and real Los Angeles locations is typical of sitcom production. The exterior does not mean Jerry lived in Los Angeles in the story; it was simply a filmed location standing in for his Manhattan neighborhood.
