RARE OLDE CARLSBAD GEM WITH NO HOA & A FULL DETACHED GUEST HOUSE! Experience the pinnacle of coastal living at 1807 Valencia Ave, a breathtakingly reimagined single-story retreat situated on a nearly 10,000 sq. ft. corner lot in the highly coveted Laguna Riviera community of Old Carlsbad. Free from Mello-Roos and HOA restrictions, this turn-key estate offers supreme privacy, unmatched multi-generational functionality, and incredible income potential. From the moment you arrive, you are greeted by striking curb appeal and an inviting, sun-drenched open floor plan thoughtfully curated for the active Southern California lifestyle. The heart of the main residence is a chef-inspired kitchen, outfitted with premium KitchenAid and LG appliances, custom cabinetry, quartz counters, and designer lighting. True luxury meets indoor-outdoor perfection in the living and dining areas, where custom Sierra Pacific panoramic wood-clad bi-fold doors vanish into the walls. This architectural masterpiece seamlessly blends the interior living space with your secluded, resort-style backyard oasis. Retreat to the main residence's primary suite, a true coastal sanctuary boasting exceptional dual-closet storage and a spa-caliber en-suite bathroom detailed with custom tilework and high-end fixtures. Separated by lush, mature landscaping for optimal privacy, the crown jewel of the property is the fully detached Guest House (ADU). Complete with its own private bedroom, a luxurious full bathroom, a spacious living room, and a modern kitchenette, it is the ultimate, self-sufficient setup for hosting extended family, running a quiet professional studio, or generating long-term or short-term rental income. The fully fenced grounds are an entertainer’s dream and a master gardener's paradise. Step outside to enjoy your own private, producing micro-farm featuring a thriving vegetable garden, established grape vines, and a lush orchard boasting nine varieties of mature fruit trees, including highly sought-after avocados. The exterior also features a dedicated dog run and massive covered parking tailor-made for an RV, boat, or recreational toys. Complete with fully paid-off solar panels, high-end energy-efficient windows, and an unbeatable location just minutes from the Agua Hedionda Lagoon, Carlsbad Village dining, world-class beaches, and highly-rated Carlsbad Unified schools. This is a legacy property that rarely hits the market!
