There's a mansion bigger than the White House in Hillsborough
Built in 1915, Carolands was the second-largest home in the country when it was built at just over 65,000sqft. It boasts 98 rooms (NINETY-EIGHT), four kitchens, 17 bedrooms, 18 bathrooms, and there are separate rooms designed for flower arranging, polishing silver, baking, and storing vegetables. What. The. Fuck. It was shuttered for 20+ years on two separate occasions, during which time porn was secretly filmed there, and a caretaker assaulted two teenage girls on the property, one of whom died. Then in 1991, Charles "Principal Owner of the SF Giants" Johnson bought it and his wife spent $20 million restoring it. It's now closed to the public and occasionally used for charity functions/98-person sleepovers.
