San Bruno is a city in San Mateo County, California, on the San Francisco Peninsula, roughly 10 miles south of San Francisco. Incorporated in 1914, it reported a population of 43,908 at the 2020 census. The city occupies a strategic position near San Francisco International Airport and has long been shaped by its transportation role. The Tanforan shopping center stands on the site of a former racetrack, airfield, and military center, a reminder of the area's layered history. In 2003, BART's San Mateo County extension reached San Bruno, linking the city directly to San Francisco, the East Bay, and the airport, and cementing its appeal as a commuter community on the Peninsula. U.S. Highway 101 and Interstate 280 frame the city, and Caltrain service is available nearby. San Bruno is a largely residential city with a mix of single-family homes — including mid-century ranch houses — townhouses, and apartments, and a family-oriented, diverse population. Neighborhoods such as Crestmoor, Belle Air Park, Mills Park, and Rollingwood are known for their community feel and access to parks and schools. The city is served by the San Bruno Park School District for elementary grades and the San Mateo Union High School District for secondary education, including Capuchino High School, and Skyline College provides a local higher-education option. San Bruno appeals to families and commuters seeking Peninsula living with BART access, proximity to the airport and major employers, and a housing stock that is comparatively more attainable than some of its higher-priced neighbors. San Bruno Mountain rises to the north, providing open space, hiking trails, and a defining presence on the city's landscape.
