What is the name of House’s apartment in House M.D.?

House’s apartment in House M.D. is identified as 221B Baker Street. The address is a deliberate reference to 221B Baker Street, the fictional London home of Sherlock Holmes.

The connection reinforces the show’s inspiration. Gregory House functions as a medical detective: he observes unusual details, tests hypotheses, distrusts easy explanations, and often reaches a diagnosis through deductive reasoning. His friend James Wilson parallels Dr. Watson in the broad structure of the relationship.

House’s address is in Princeton, New Jersey, even though Baker Street is most famously associated with Holmes in London. The reference is therefore an allusion rather than a claim that the character lives in the original literary location.

Some viewers remember the apartment number but omit “Baker Street,” while others assume the address is 221B Princeton Street. The canonical Holmes reference is “221B Baker Street,” making it a particularly clear example of the series’ detective-story framework.
