709-711 S B Street presents a rare opportunity to acquire a historic two-story commercial building near Downtown San Mateo. The property consists of approximately 5,005 square feet and is configured with two separate units, offering flexibility for an owner-user, investor, or redevelopment buyer. The ground floor (Suite 709) was formerly operated as Yuppie Cantina, featuring an existing bar and kitchen buildout along with a private fenced backyard patio area, making it well suited for a restaurant, bar, or hospitality concept. The second floor (Suite 711) was previously occupied by School of Rock and offers a wide-open layout, high ceilings, and excellent natural light, creating an ideal setting for creative office, fitness studio, music/arts education, or collaborative workspace. The property benefits from C1 (Neighborhood Commercial District)-R5 zoning, allowing a variety of commercial and mixed-use possibilities, including potential retail, office, service, or residential integration (buyer to verify). Positioned just south of Downtown San Mateo, the property is surrounded by dense residential neighborhoods, restaurants, and retail amenities, offering strong long-term repositioning potential.
