About San Mateo

An influx of workers and residents are transforming San Mateo. Downtown is undergoing a renaissance, as the Bay Meadow’s redevelopment has successfully attracted Guidewire Software and other growing tech firms, as well as thousands of new renters. Just north at Burlingame Point, Facebook will be expanding into a new campus large enough for more than 3,000 workers.

San Mateo’s mid-peninsula location is ideal for businesses with workforces that commute from disperse Bay Area suburbs and cities. Caltrain runs north to San Francisco and south to San Jose, providing a popular public transportation option with three stations in the area, including one in downtown. San Mateo’s position at the midpoint between San Francisco and San Jose allows for a reasonable commute from the largest cities in the Bay Area. U.S. Route 101 and the El Camino Real traverse the area running north to south, while the San Mateo-Hayward Bridge connects drivers to the East Bay.

San Mateo boasts one of the largest and most prominent suburban downtowns in the San Francisco Peninsula. It’s a well-established yet growing entertainment and retail destination with shops and restaurants lining historic buildings. At San Mateo’s southern end, the Hillsdale Shopping Center contains over 120 stores. The area appeals to a diverse range of professionals, particularly in the fields of technology, healthcare, and finance. The largest employers nearby include Sony, GoPro, Marketo, SolarCity, NetSuite, Fisher Investments, and Franklin Templeton Investments.
