Will's apartment is the rent-controlled apartment located on the 9th floor of 155 Riverside Drive in the Upper West Side in Manhattan, New York. It is the most used location in the series, being the residence of Will and for most of the series with Grace. Jack has referred to it as "the apartment that sex forgot."
Will moved in sometime before the series, presumably with his then-boyfriend Michael as it was stated that they lived together when they were still dating. Will also became the president of the tenants' association. After his argument with Grace about the opening of fireplaces, Grace runs against him during the elections and wins.
At the start of the series, Jack briefly moves in with Will before being asked to moved out so Grace can have a place to stay after leaving Danny. Jack regularly comes to the apartment as he says he "lives there when Will is at work".
After the series
The set for Will's apartment was donated by series co-creator and alumni Max Mutchnick to Emerson College Library in Massachusetts.
- Grace mentions that the apartment has a view of Central Park and of New Jersey from her bedroom window.
