Rare opportunity to add up to 6 ADUs on this large DOUBLE LOT with existing Duplex, detached Garage, Alley access, and strong SDSU rental demand. ADU Feasibility Study available. Sale includes adjacent lot (468-230-15-00) for a combined 16,892 sq ft. Zoned RS-1-7 in a Transit Priority Area. Duplex consists of 2x 2bed/1bath units with new waste & sewer lines in crawlspace, new windows, & new exterior paint. The larger unit is a generous 1,062 sq ft with hardwood floors, fresh interior paint, and is currently vacant which may allow reconfiguration into a 3/2 for added upside. The other unit is 822 sq ft with hardwood under carpet and currently rented MTM (long-term tenant far below market). Both units have central AC & heating. Detached structure is 520 sq ft and currently contains a laundry room & 2x 1-car garages that may be converted while still leaving plenty of space for off-street parking. Rear private road from alley ends at the property so there is no through traffic. Perfect for a buyer looking to live in one and rent the other with massive equity-building potential, or a savvy investor looking for a development deal. Property was fumigated in Oct 2025 with Termite Clearance. Pre-Inspection & repairs completed.
