Annie's apartment was a one room loft located above a marital aids store called "Dildopolis". It was first seen briefly in the Season 2 premiere in a montage with the rest of the study group's residences. It was later fully seen in the episode "Celebrity Pharmacology 212". In Season 3, Annie would accept Abed's invitation and move in with him and Troy in their apartment. Its last appearance was in the Season Three episode "Studies in Modern Movement".
In the study groups second year at Greendale, Annie's the extent of her estrangement from her family including her living situation would be revealed. At the start of the 2010 Fall semester her apartment--along with the other study group member's homes--was briefly shown ("Anthropology 101"). While the decor was in keeping with Annie's stylish sensibilities, it was noticeable that metal bars were covering the windows to her room, hinting at the type of neighborhood she lived in; this was further alluded to when she mentioned to Jeff that she lives in a bad neighborhood ("Conspiracy Theories and Interior Design"). It was confirmed that she lives in a bad part of town when Troy dropped her off after his birthday celebration at a nearby bar ("Mixology Certification"). Later that year, Pierce followed Annie home and discovered her apartment is located above a Dildopolis store ("Celebrity Pharmacology 212").
In the study groups third year at Greendale, the stress of living in such a dangerous place seemed to be getting to Annie. While attending the housewarming party at Troy and Abed's apartment, she acted anxiously whenever the buzzer went off. In one of the six different timelines shown, it is discovered by Troy that she had a gun in her purse ("Remedial Chaos Theory"). Previously Annie was shown to be taking a self defense course ("Paradigms of Human Memory"), the appearance of the gun indicated she took her need for self protection in her place of residence a step further. Abed would later extend an offer for her to move in with him and Troy which she happily accepted. Later, the study group--minus Jeff--helped her move into Troy and Abed's apartment.
Pierce tried to help her out by fixing an electrical outlet that had been destroyed by Troy but ended up making it worse. When attempting to paint over the damaged area, he accidentally sealed off the apartment and inhaled a dangerous amount of paint fumes. The apartment manager found him covered in paint and suffering from hallucinations. Annie returns to her apartment after having an argument with Troy and Abed about which room she was going to be living in and finds the mess Pierce had created. Her landord was there, taking care of Pierce, having discovered him lying in a pool of paint on the floor trying to make paint angels. Before the landlord leaves, he mentions she lost her deposit due to Pierce's antics, but Annie is just thankful for him looking after Pierce ("Studies in Modern Movement").
