Tucked away at the end of a long gated driveway, 1236 La Colina Drive offers a rare opportunity to own two separate residences on an expansive 13,200-square-foot lot in Tustin. Combining privacy, flexible living arrangements, abundant outdoor space and intriguing long-term possibilities, this distinctive property is ideally suited for multigenerational living, extended family, guests, live-in support or caregiving arrangements, buyers seeking the potential benefit of a separate income-producing residence, or those who value the convenience of single-level living. The main residence features three bedrooms and two bathrooms, while the separate one-bedroom residence offers its own kitchen, living area and bathroom. With a single-story layout and no interior steps, the second residence provides exceptional flexibility while allowing each living space to maintain a sense of privacy and independence. Some of the recent upgrades include new roof and insulation, freshly painted interior and exterior, full high speed wiring, EV charging capability, and new whole house fan. Beyond the two existing residences, the oversized grounds provide exceptional versatility for outdoor living, gardening, recreation, RV or boat parking and future possibilities. Buyers interested in expansion, additional living space or maximizing the property's long-term potential will appreciate the scale and flexibility of this unusually large Tustin homesite. Any future development, rental use or additional dwelling possibilities are subject to buyer investigation and applicable governmental approvals. Properties offering this combination of two separate residences, more than 13,000 square feet of land, privacy and flexibility are increasingly difficult to find in central Orange County. Whether envisioned as a multigenerational property, a primary residence with potential supplemental income, a flexible solution for extended family or live-in assistance, or a long-term investment in land and location, 1236 La Colina Drive presents an opportunity unlike the typical Tustin home.
