2nd Floor Ste Office 1,350 SF Rate Upon Request 
Fully built-out, partially furnished office available in the heart of Downtown San Mateo. This front-facing suite at 318 South B Street offers approximately 1,350 square feet of move-in-ready space — a private office, an open work space, two meeting rooms, a kitchenette, and a phone booth.

The suite sits one block from the San Mateo Caltrain station, with an adjacent public parking garage and immediate access to Highways 101 and 92 — connecting you to San Francisco, the Peninsula, Silicon Valley, and SFO. Restaurants, coffee, retail, and banking are all within a short walk.

Offered on flexible lease terms with a modified gross structure, the space is well suited for a professional services firm, a satellite office, or a growing company that wants a turnkey office without the build-out. Available July 1, 2026. Contact the listing broker for lease rate and to schedule a tour.
