Located on one of Eastside Costa Mesa’s tree-lined streets, 219 Lillian Pl is a stunning 3-bedroom, (additional room in ADU with bathroom) 2.5-bathroom home that has been fully remodeled within the last two years. Blending modern updates with timeless charm, this residence features hardwood floors (sanded and re-stained), all-new windows (installed 2 years ago), a new HVAC system with MERV13 HEPA filters and added AC, and a whole-house water filtration system, ensuring both comfort and efficiency. The kitchen and two bathrooms have been fully remodeled, including new appliances and an added indoor laundry area (previously outside). Fresh paint inside and out, along with custom front and back doors, enhance the home’s inviting aesthetic. Outdoor living is just as impressive, with a spacious deck, a custom fire pit, and lush landscaping with irrigation and fruit trees. The standalone sauna and spa deck, added just 1.5 years ago, create a true backyard oasis. A private guest house (ADU) sits in the backyard, featuring a full renovation with a new mini-split system, SMEG fridge, Murphy bed with cabinets, a fully updated bathroom, and a tankless water heater. Its separate entrance via a newly refinished alleyway adds convenience and privacy. Additional upgrades include new outdoor and indoor lighting, a new fence and gate in the front yard, new backyard fencing with trees, a storage barn shed, mold remediation and crawl space encapsulation, and newly added pathways with irrigation in the front yard. Ideally situated just minutes from the beach, Back Bay, John Wayne Airport, and world-class dining and entertainment, this exceptional home offers the perfect blend of modern convenience and coastal charm.
