What address does Gregory House give for his apartment in House M.D.?

Gregory House gives his apartment address as 221B Baker Street in House M.D.

The address is a direct reference to 221B Baker Street, the fictional London home of Sherlock Holmes. House is modeled in part on Holmes, and the connection appears in several details beyond the shared emphasis on deduction. House’s name also resembles “Holmes,” and Dr. James Wilson occupies a Watson-like role as his close friend and sounding board.

In the series, House’s apartment is associated with his solitary habits, musical interests, drug use, and private attempts to solve problems away from the hospital. The address helps signal the literary inspiration behind the character rather than identifying a real Princeton residence.

The Holmes reference can cause confusion because Baker Street is in London, while House’s professional life is based in New Jersey. The address is therefore a fictional and allusive detail within the show, not evidence that House lives in the United Kingdom.
