Beach Chic meets Cardiff Cool! Perched atop one of the highest lots west of Interstate 5 in coveted Cardiff-by-the-Sea, this exceptional coastal property presents a rare opportunity to enjoy a serene beach retreat, secure a high-performing income property, or explore future development potential. Situated on an elevated 5,000 sq ft lot with horizon sunset and peek ocean views, the property offers the possibility to build two homes with potential ocean views on two underlying legal lots. Currently configured as a turnkey, single-level coastal retreat, the home was completely renovated in 2023 by renowned design/build firm Buechler Builders. The beautifully updated main residence features 4 bedrooms and 3.5 bathrooms across approximately 1,408 sq ft, complemented by an attached private 259 sq ft ADU — ideal for guests, rental income, or multi-generational living. Each residence enjoys its own private entrance, garage, legal address, and separate gas and electric meters. Recent rental history totals approximately $12,900/month ($9,000 main house; $3,900 ADU). Inside, white oak flooring, soaring open-beam cedar ceilings, and abundant natural light create a warm yet refined coastal aesthetic. The open-concept layout flows seamlessly from the quartzite chef’s kitchen with oak cabinetry and stainless-steel appliances into the living and dining spaces. Three of the four bedrooms open directly to private outdoor patios through French or sliding doors, while two ensuite bedrooms provide added comfort and flexibility. Professionally landscaped grounds offer three private patios, a tranquil water feature, two firepits, and lush greenery enhanced by automatic ambient lighting — perfect for entertaining or relaxing year-round. The newly built 2023 ADU includes a full kitchen, full bathroom, stacked washer and dryer, stainless appliances, and a spacious private deck with firepit, creating a peaceful standalone retreat or premium rental opportunity. Future development possibilities further enhance the value, with two underlying legal lots allowing potential construction of a legal twin-home configuration. Conceptual plans envision approximately 2,150 sq ft attached single-family residences, each with its own ADU and two-car garage (buyer to verify). Additional highlights include a 2-car garage for the main home, 1-car garage for the ADU, cedar shake shingle exterior showcasing true coastal character, and a quiet, private top-of-the-hill location within the highly desirable Cardiff and San Dieguito school districts. A rare blend of lifestyle, income potential, and future upside in one of North County’s most sought-after coastal communities.
