What address does Dr. House use as his home address in House, M.D.?

Dr. House uses 221B Baker Street as his home address in House, M.D.

The address is a deliberate reference to 221B Baker Street, the fictional London home of Sherlock Holmes. House was heavily inspired by Holmes: both characters are brilliant investigators, rely on deduction, challenge conventional thinking, and have difficult relationships with ordinary social expectations.

In the series, House’s apartment is located in Princeton, New Jersey, despite the famous London address. The reference works as an in-universe clue to the character’s literary model rather than as a realistic geographic claim.

The address is often written with a capital letter and the suffix “B.” It should not be confused with 221A Baker Street, another variation sometimes used in adaptations or fictional references. The House address is one of the show’s most direct and easily overlooked connections to Sherlock Holmes.
