Welcome to your next chapter in vibrant Eastside Costa Mesa - a lovingly kept family compound, privately owned for nearly 40 years and now ready for new memories. Nestled on a generous 8,276 sq ft lot just steps from the Newport Beach border, this rare property feels like getting three homes for the price of one: a total of 2,693 sq ft across three separate legal living units. The cheerful front house is a classic single-level Eastside gem with 2 bedrooms, 1 bath, a single-car garage and private laundry. Tucked behind it, you'll find a two-story end unit with 2 bedrooms and 1.5 baths plus its own detached garage, and above the three garages sits a bright 2-bedroom, 1-bath carriage unit - the rear homes share a convenient laundry area. Imagine hosting celebrations in the spacious yard, strolling to award-winning schools, and popping over to the shops and restaurants on 17th Street - or hopping on your bike for a quick ride to one of California's best beaches. Whether you're an investor looking for steady income or an owner-occupant craving flexibility and rental help, this property offers endless possibilities and a prime location that's hard to beat. Come see the potential and bring your vision to life! Property will be delivered vacant .
