899 W San Carlos St is an exceptional retail investment opportunity located in the thriving city of San Jose, California, positioned along the highly trafficked West San Carlos corridor and offering a rare combination of central location, flexible commercial and residential use, and long-term redevelopment potential. The property is a short walk to Willow Glen, minutes from Downtown San Jose, and down the road from Westfield Valley Fair Mall, providing convenient access to retail, dining, and services throughout the South Bay, with Diridon Station nearby and easy access to Interstate 280 for regional commuting. Zoned Mixed Use Commercial (MUC) and located within the West San Carlos Urban Village Plan, the site is targeted for higher-density, mixed-use, and transit-oriented development, with recent and ongoing projects in the surrounding Sunol-Midtown neighborhood supporting strong long-term land value. The existing improvements include seven total bedrooms across three components: a front mixed-use/live-work unit (2BR/1BA), a central primary residence (2BR/1BA), and a rear ADU (3BR/2BA), making the property well suited for investors or an owner-user seeking a live-work setup with on-site flexibility, multigenerational living, or supplemental rental income. Additional features include a large central patio currently configured as a garden and play area with potential for reconfiguration to support future commercial parking, as well as a spacious basement in the main house offering added storage and utility space. Supported by San Jose’s strong employment fundamentals, low vacancy levels, and Silicon Valley location, the property presents a compelling opportunity for retail tenants and investors alike due to its proximity to major employers, transportation corridors, and lifestyle amenities.
