What address does Gregory House live at in House, M.D.?

Gregory House lives at 221B Baker Street in House, M.D.

The address is a deliberate reference to 221B Baker Street, the London home of Sherlock Holmes. House is modeled partly on Holmes: both characters are exceptionally observant, solve difficult cases through deduction, and use unconventional methods that frustrate colleagues. The address therefore acts as an additional clue to the character’s literary inspiration.

In the series, House’s apartment is in Princeton, New Jersey, not London. The location appears in several episodes and becomes part of the show’s visual language, especially when House is shown practicing music, receiving visitors, or dealing with personal problems away from the hospital.

Viewers can confuse the fictional address with Holmes’s original setting or assume that House lives at a New Jersey address unrelated to the reference. The canonical number and street name are specifically 221B Baker Street, echoing Arthur Conan Doyle’s detective.
