Key Highlights

The Baywood Knolls neighborhood in San Mateo, California, was originally part of the historic Polhemus Estate, which belonged to one of the city's founding families. Developed primarily in the late 1940s and 1950s, the neighborhood's architectural character reflects mid-century contemporary design, featuring clean lines and modern layouts that contrast with the older, more romantic Tudor and Mediterranean Revival styles found in the adjacent Baywood neighborhood. In 1989, a citywide historic building survey, in consultation with the State Office of Historic Preservation, identified Baywood Knolls as a potentially significant historic district due to its high degree of architectural consistency and its representation of the post-World War II suburbanization of the San Francisco Peninsula.
