Scranton Business Park

Scranton Business Park is where the Dunder Mifflin Scranton office (the main setting of the show) is located. Its address in the show is 1725 Slough Avenue in Scranton, PA. The place/street itself in Scranton doesn't actually exist, as the address is actually a reference to the British version of The Office, which is set in Slough, England. In the season six finale, Whistleblower, Dwight buys the Business Park.

Behind the scenes

 * The first season was filmed in a real office building. It used the production offices of studios 1 and 2 at Century Studios in Culver City (3322 La Cienega Place), and production was moved to what would normally be the sound stage area. By 2012, the company has lost significant business due to tenants being lured away by states which offer filming enticements. By 2014, the studio closed its doors. The building has been remodeled, so the original offices no longer exist.
 * The location had previously been used by J. J. Abrams when he worked on Felicity: The conference room was previously J. J. Abrams's office. Abrams got a feeling of deja vu when he came to the set to direct an episode.
 * Starting in the second season, the show was filmed at Chandler Valley Center Studios at 13927 Saticoy Street in Van Nuys. The office was reproduced down to the last detail, with small changes for practical reasons: Michael's office was made a little bit larger to make it easier to film in. The kitchen was also widened for the same reason.
 * Scenes in the alleyway next to the warehouse must be filmed at 3:30pm. The narrow alley makes it impossible to set up artificial lighting, and the building and hedges block the sun most of the day. There is only a narrow window of time each day when the sun shines into the alley.
