The Shay residence is where most of iCarly takes place. It is a three-story apartment with a private elevator in Bushwell Plaza, apartment number 8-C.
The first floor, which rests on the eighth floor of the building, has a living room with a connected kitchen (with a fully functional sink with real plumbing on set). Spencer's bedroom is on the first floor as well, near the Shays' bathroom. Spencer likes to call his bedroom "the Chamber of Awesomeness" and has adorned it with random decorations, as shown in a gallery on iCarly.com.
The stairs along with the cargo elevator are both located towards the back of the apartment.
The second floor, the building's ninth floor, never seen on-screen until iGot a Hot Room, houses Carly's bedroom. There is a second bathroom on the second floor, mentioned in iGive Away a Car, iHave My Principals (Carly has taken showers in both episodes), and in iPie, where Sam locks herself in the bathroom to eat a piece of pie, and is finally seen in "iToe Fat Cakes". The possibility of other rooms is also open.
The third floor, the building's tenth floor, is better known as the iCarly studio. It is also known to be a sort of space behind the studio, where iCarly guests wait to be introduced onto the show.
The apartment also comes with its own "built-in" cat, who's currently stuck behind the wall. This cat was only mentioned once.
- The Shays' living room is decorated with collections of insulated drink containers, older model transistor radios, stereos and telephones and models of gummy bears. There is no mention as to which family member collected these items. No doubt it was Spencer. He probably found them at the junkyard.
- The Shays' downstairs bathroom has never so far been shown in the series.
- Perhaps the oddest item in the living room is a yellow diaper pail of the sort used to soak cloth diapers prior to washing, that sits close to front door of the apartment. In "iStakeout" Carly uses this pail to clean up trash left by the cops.
- On a shelf in the kitchen is a "cookie time" cookie jar that appears identical to one that was used on the set of "Friends" for many years.
- In the kitchen, most of the fridge magnets appear to be different in every episode.
- In between the living room and the kitchen is a counter which usually has two red bar stools of the same type as those used in the Groovie Smoothie, except in "iWant More Viewers" and "iWant a World Record" and "iPie", when there are three red stools. In "iPsycho" Spencer purchases a granite counter top to replace the broken wooden one, but it completely crushes the counter. However in subsequent episodes the counter was rebuilt with its original wooden top and the granite top was never used, which seems odd given that granite counter tops are quite expensive.
- It was mentioned by Dan Schneider that Spencer's room after iChristmas was rebuilt to be Carly's new bedroom.
It is unknown if every apartment unit in the buildling has three floors. It is speculated that each unit does not have three floors, as Marty Klemish lives in 7-C, directly below the Shay's residence. It is assumed that his apartment unit only has one floor. Because of this, it can be speculated that the Shays' apartment is special in comparison with the other apartment units.
