Welcome to 1184 Dorset Lane, a beautifully reimagined single-story home on a coveted corner lot in one of Costa Mesa's most walkable neighborhoods. Behind the classic California ranch curb appeal, with fresh exterior paint, a brick chimney accent, and low-maintenance turf landscaping, is a home that's been completely reimagined with today's taste. Step inside to a wide-open great room where the kitchen, dining, and living spaces flow together under recessed lighting and wide-plank flooring. The kitchen anchors it all: a generous quartz island with seating for four, shaker cabinetry, and stainless appliances, all designed for the way people actually live, whether that's entertaining, working from home, or everyday family life without walls in the way. The main house offers 3 bedrooms and 2 baths, all finished with the same clean, modern palette throughout. Rounding out the value are owned solar panels, already paid off, keeping utility costs low from day one. What truly sets this property apart is the brand-new (2025) attached ADU. A fully permitted 2-bedroom, 1-bath unit with its own separate entrance and finishes to match the main home. Whether you're housing extended family, hosting guests, or generating rental income, an ADU of this size and quality on a corner lot is genuinely rare to find in Costa Mesa. It's the kind of built-in flexibility that pencils out whether you're an owner-occupant looking to offset your mortgage or an investor eyeing strong dual-unit cash flow. Just minutes from the Westside Costa Mesa restaurant scene, South Coast Plaza, and a short drive to the coast, this is turnkey coastal-adjacent living with a rare income lever built right in.
