Hillsborough is a residential community on the San Francisco Peninsula, located between Interstate 280 and El Camino Real, roughly seventeen miles south of San Francisco. The town is known for its wooded hillsides, winding roads, and strong emphasis on preserving natural beauty. Development policies prioritize low-density living and the maintenance of open space, contributing to Hillsborough’s quiet, private atmosphere and rural character despite its central Peninsula location.

Education is an important consideration for residents. Hillsborough operates its own public elementary and middle school system, while public high school students attend schools within the San Mateo Union High School District. Many families also choose nearby private school options, including college preparatory programs located within Hillsborough and neighboring communities.

Housing in Hillsborough is defined by large estate properties and expansive lots. Zoning regulations require minimum lot sizes greater than one-half acre and minimum home sizes of approximately 2,500 square feet, which limits density and effectively prevents condominium and townhome development. These standards have helped maintain a consistent residential character centered on single-family estate homes.
