San Carlos sits at the heart of the San Francisco Peninsula, tucked between Redwood City and Belmont in San Mateo County, earning its long-held nickname "The City of Good Living" through a mix of quiet residential streets and a walkable downtown core. The city covers just six square miles, yet packs in a strong sense of place anchored by Laurel Street, which serves as the commercial and social hub where coffee shops, wine bars, and local restaurants draw residents out on foot most evenings. A centrally located Caltrain station makes commuting north to San Francisco or south to San Jose straightforward without a car, and proximity to both Highway 101 and Interstate 280 adds flexibility for those who drive.
The housing stock reflects the city's blend of established neighborhoods and newer infill development.
