Step into a rare, shovel-ready opportunity in a desirable Concord neighborhood. This is a brand-new, standalone 6,562 sq. ft. parcel (APN 132-121-006) created through a fully approved SB-9 lot split - complete with a City of Concord-issued building permit and fully approved architectural and structural plans for a brand-new 3,604 sq. ft. duplex. The approved plans include two spacious 1,802 sq. ft. units, each offering 3 bedrooms, 2.5 baths, a private porch and patio, open kitchen and dining areas, and a dedicated laundry room, ideal for owner-occupants who want rental income, multi-generational living, or an investor-ready new construction project. Each unit includes uncovered parking, and the project is fully Title 24 energy-compliant with a photovoltaic system already engineered into the design. The heavy lifting is done: architectural and structural plans, energy compliance reports, civil/grading and erosion control plans, and a City-approved building permit are all in hand, just pull the permit and start building. Located minutes from BART, shopping, and easy freeway access, with the charm of Concord and the convenience of nearby Walnut Creek.
