Discover a rare development opportunity in the heart of Olde Carlsbad. This 34,500 sq. ft. (.79 acres) parcel is one of the few remaining premium lots in the 92008 zip code, offering significant potential in a highly sought-after coastal neighborhood. Tax records currently reflect the address as 4269 Hillside Drive due to a previous submission for a lot split. A nearby comparable lot at 4407 Park Drive sold last year for $1,000,000 and is currently under city review for a 6,000 sq. ft. home plus an ADU, despite having less usable space because of environmental constraints. This underscores the value and development capacity of the Hillside Drive parcel. Privately situated and bordered by mature greenery, the property features an elevated setting and a freestanding layout that supports a wide range of design possibilities. Whether planning a modern custom estate with a gated driveway off of Hillside, a multigenerational configuration, or an income-producing ADU, the lot offers the space and flexibility to accommodate various architectural plans. Water, sewer, and electricity are already on-site, streamlining the transition from design to construction. The generous footprint also allows room for the possibility of a pool, landscaped grounds, and expansive outdoor living areas. The location further enhances the value of this property. Residents will enjoy close proximity to Carlsbad’s beaches, the Village, local boutiques, restaurants, cafés, and year-round community events. Award-winning Carlsbad schools are within walking distance, and the lot provides convenient access to everything North County has to offer. This is an exceptional opportunity to develop a private coastal residence in one of Carlsbad’s most established and desirable neighborhoods.
