Set on a remarkably private, south-facing third of an acre in Marine Terrace - one of the Mesa's most coveted neighborhoods - 1437 San Miguel Avenue is a rare offering that pairs a beautifully renovated home with an exceptional coastal lifestyle. Just a short walk to Shoreline Park and Washington School, and minutes from the beach, harbor, Lazy Acres, and downtown Santa Barbara, this property captures the essence of relaxed, refined coastal living. Tucked behind lush landscaping and mature trees, the home unfolds as a quiet retreat - serene, sun-filled, and deeply private. The 3-bedroom, 2-bath residence spans approximately 1, 388 square feet and has been thoughtfully reimagined with an open layout, reconfigured entry, expansive sliders, and seamless indoor-outdoor flow. The kitchen anchors the home with Thermador appliances and clean, modern finishes, while both bathrooms and the laundry room have been fully renovated. The primary suite is privately separated from the guest rooms and features a custom California Closet and a bespoke vanity. Extensive upgrades include a new roof, new gas and water lines from the street, whole-house air conditioning, updated electrical with an additional panel, security system, EV charger, outdoor sound system and lighting, and a newly built deck- reflecting a comprehensive renovation that blends infrastructure, comfort, and design. The most recent remodel was completed by McAllister, known for work on notable luxury residences throughout California. Outdoors, the property lives like a private garden estate. The expansive double-lot setting offers extraordinary space and versatility, with a sun-drenched south-facing yard, mature oak and jacaranda trees, and a landscape curated for both beauty and lifestyle. Highlights include multiple entertaining areas, an outdoor shower, hot tub, putting green, rose garden, chicken coop, orchard, and four redwood raised garden beds. The property features eight mature fruit trees: grapefruit, orange, lemon, lime, cherimoya, tangerine, and apple. A new driveway and detached shed complete the grounds. Quiet, peaceful, and exceptionally private, 1437 San Miguel Avenue offers a rare combination of land, location, and thoughtful renovation on one of the Mesa's most beloved streets -neighborly, low-traffic, and ideally positioned for the very best of Santa Barbara coastal living.
