A rare canvas in the heart of West Chula Vista sits 15,000 square feet of possibility on desirable First Avenue. Set on one of the area’s increasingly hard-to-find oversized lots, this property pairs a classic 1949 four bedroom, three bath residence with genuine room to dream. The expansive grounds and convenient alley access open the door to exciting next chapters: a thoughtful renovation, a custom rebuild, or a multi-unit vision under California’s SB 9 lot split provisions, with room for primary homes, ADUs, and junior ADUs across two future homesites (buyer to verify all zoning, density, and development options with the City of Chula Vista). The alley isn’t just practical, it’s a developer’s friend, offering rear-entry garage potential, flexible parking layouts, and smarter site design for whatever comes next. Location does the rest of the talking. You’re moments from the H Street corridor’s shops and dining, quick freeway access, quality schools, and the energy of the Chula Vista bayfront’s ongoing transformation. This is a neighborhood on the rise, and large infill parcels like this simply don’t come along often. Whether your plans call for restoring a charming mid-century home, holding a well positioned rental, or unlocking the full development potential of a third-of-an-acre lot, this is your invitation to build what’s next in the South Bay.
