Looking for a home with a 6 Car Garage with ADU or JADU potential? We have the one for you. Set at the end of a peaceful cul de sac in one of Fullertons most established neighborhoods, this single level home offers both space and serenity. Spanning 2,467 square feet on a generous 12,540 square foot lot, the property is thoughtfully designed for comfortable living and easy entertaining. From the moment you arrive, the long private driveway and impressive six car detached garage (approx 42' x 24' and 1,000 sq ft) set the tone for whats inside. The garage offers rare flexibility, ideal for car enthusiasts, storage, or a future ADU or JADU conversion. Step inside and youll find a bright, open layout with four spacious bedrooms and three full bathrooms, and an office or bonus room or optional 5th bedroom just off the family room with access to the gorgeous backyard. The living areas flow naturally, with large windows framing views of the backyard and letting soft natural light fill the home. The kitchen serves as the homes centerpiece, connecting to a casual dining space and family room where everyday life unfolds. Just outside, the backyard feels like a private retreat with a sparkling pool and spa surrounded by mature landscaping, perfect for gatherings or quiet weekends at home. Calle Ultimo (translated to "the last street") is the kind of street where neighbors look out for each other and kids play freely, a pocket of calm that feels far from the rush of city life. Fullerton is known for its strong sense of community, rich history, and safety. Local parks, golf courses, and the Famous Fullerton Loop spanning 11+ miles of walking & biking trails are close by, along with easy access to downtown Fullertons restaurants and coffee shops. Families appreciate the homes location within the award winning Fullerton Joint Union High School District, known for schools like Sunny Hills High and Parks Junior High. 2207 Calle Ultimo is more than a home. Its a rare combination of space, privacy, and community in one of North Orange Countys most sought after settings.
