Costa Mesa CA Real Estate & Land for Sale

LAND WITH PLANS READY TO ISSUE (RTI). Skip the design and entitlement process. This rare Eastside opportunity comes with fully developed, ready-to-issue architectural plans for a striking modern compound, so you can break ground almost immediately instead of starting from a blank page. Set on an oversized 7,700 square foot lot (55' wide x 140' deep) on a quiet interior street in the central Eastside, the approved plans call for an approximately 4,300 square foot two-story residence: a 3,700 square foot main home with 4 bedrooms and 4 bathrooms, an open-concept great room, chef's kitchen, main-level guest suite, dedicated bar/lounge, and attached 3-car garage plus a detached 600 square foot ADU positioned beyond a resort-style pool and spa, creating a true compound setting that's rare at this price point. The owner has also already replaced the sewer line out to the street, removing one of the most common infrastructure hurdles on an Eastside rebuild. Ideally located just blocks from the Back Bay Nature Trails, East 17th Street shopping and dining, and with easy access to all major transportation corridors, Newport Beach, and OC's beaches, this is a rare chance to acquire land, design, and a construction-ready path forward in one of Costa Mesa's most desirable neighborhoods without the many months of lead time a typical ground-up project requires.
