What is Dr. House’s fictional address in House M.D.?

Dr. House’s fictional address in House M.D. is 221B Baker Street.

House lives at 221B Baker Street in Princeton, New Jersey, according to the series. The address is a direct reference to 221B Baker Street in London, the famous fictional home of Sherlock Holmes. House’s surname, deductive methods, and relationship with Wilson also echo elements of the Holmes stories.

The reference is intentional rather than a claim that House lives in London. The television series relocates the address to its fictional New Jersey setting while using it as a character clue. House’s apartment is shown as a private space that reflects his isolation, habits, and unconventional lifestyle.

Fans sometimes remember only the number and omit Baker Street, or confuse the address with the hospital. The complete canonical address is 221B Baker Street, not Princeton-Plainsboro Teaching Hospital.
