The Tunt Mansion is where Cheryl Tunt lives in a high class neighborhood of New York City. It is right next door to the Roosevelt Mansion. It is characterized by a lot of ornate moldings, large spacious rooms and ultra-high ceilings. It has been passed down through the Tunt family, inherited from Cornelius Tunt, Cheryl's great-grandfather.
It is unknown whether or not Cheryl has to share the living space with her brother Cecil Tunt.
It has only made one appearance in "El Secuestro."
