Caltrain Headquarters Office Request for Information (RFI)

Background Information

Caltrain currently shares headquarters space with SamTrans in San Carlos near the San Carlos Caltrain Station. In 2025, SamTrans is planning to move to a new headquarters building located near the Millbrae Caltrain Station, offering Caltrain the possibility of continuing to co-locate. While Caltrain is evaluating this opportunity, the agency is also exploring options to lease or purchase separate office space near a Caltrain station.

Caltrain is seeking to acquire 27,000 – 35,000 square feet of office space on the San Francisco peninsula near a Caltrain station (between San Francisco and Diridon stations), either through a lease or purchase agreement. Caltrain has developed an indicative space program and invites property owners, managers, or their qualified broker representatives to submit available properties for consideration. Caltrain is interested in hearing from the private sector as well as public entities.
