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.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
