Exceptional Development Opportunity for Owner-Users, Investors, Contractors, and Developers! Currently configured as a duplex, featuring a 2-bedroom, 1-bath unit and a 3-bedroom, 1-bath unit. This property sits on a generous 8,100 sq ft lot just minutes from vibrant downtown Sunnyvale. Enjoy proximity to excellent schools, parks, shopping, dining, Caltrain, major tech employers, and transportation hubs. Previously approved for subdivision into two separate lots, the property was in process to obtain permit to construct two brand-new single-family homes, each over 2,300 sq ft on its own lot. Please note that the original subdivision approval has expired; the new owner will need to reapply. Larger or more units possible with ADU and SB9.
All information regarding lot size, square footage, and development potential is believed to be reliable but is not guaranteed. Buyers are strongly encouraged to conduct their own due diligence, including independent verification of square footage and development feasibility under current regulations.
