Heinz Doofenshmirtz founded the company at an unknown point prior to the movie. The overall structure of the building is identical to its 1st Dimension counterpart, but it also has a two-building extension, the tallest of which is the location of Doofenshmirtz's main office. The company was apparently dedicated to only constructing and mass-producing and entire army of giant robots called the Norm Bots. When Doofenshmirtz and his family successfully conquered the Tri-State Area with the Norm Bots, it allegedly took control of every business in the region. Ever since then, it has proven to be a more successful company for the next five years, even far more successful than the original Doofenshmirtz Evil Incorporated.
It is unknown if the building is the only building used by Doofenshmirtz, or if there is also other DEI buildings like that of the 1st Dimension DEI, like a 2nd Dimension Doofenshmirtz Abandoned Self-Storage or a 2nd Dimension Doofenshmirtz Abandoned Vacuum Cleaner Factory.
It has its own logo.
It has been mostly likely closed down after Doofenshmirtz's arrest.
