What is the title of House’s apartment building address in House M.D., echoing Sherlock Holmes?

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

The address is a direct nod to Sherlock Holmes, whose fictional London home is 221B Baker Street. House’s name, methods, drug use, musical interests, and relationship with Wilson also contain parallels to Holmes stories and characters, although House is a physician rather than a consulting detective.

In the series, the address appears as House’s residence in Princeton, New Jersey, creating a deliberate transplant of the famous Holmes location into the show’s modern medical world. The reference rewards viewers familiar with Arthur Conan Doyle’s detective.

The Holmes address is commonly written as 221B Baker Street, not 221A Baker Street. Grimmauld Place belongs to the Harry Potter universe, while 10 Downing Street is the British prime minister’s official residence.
