Living in Carolands area
The Carolands area surrounds one of the Peninsula's most famous landmarks, the Carolands Chateau, a 1910s French-style mansion built for Pullman heiress Harriet Pullman Carolan. The neighborhood around it is classic Hillsborough: winding, wooded roads, large lots, and a mix of mid-century custom homes and newer estates, many with sweeping views. Prices have climbed steadily, with the 2026 median so far at $6.8M, and well-priced homes still move quickly (about two weeks on market in 2025).
Parking & walkability: Like all of Hillsborough, this is a driving neighborhood. There are no sidewalks on most roads and no shops within town limits, since Hillsborough is entirely residential. Parking is never an issue, though, with long private driveways and multi-car garages. Downtown Burlingame and San Mateo are about 5 to 10 minutes away, and Highway 280 is close.
