Motivated seller! 240 E. Mendocino St. presents a remarkable opportunity to create your dream home in one of Altadena's most coveted and historic neighborhoods. Nestled away from the street, this peaceful and private lot once housed the carriage house for the iconic and still proudly standing Villa Carlotta, offering a unique connection to the area's rich architectural legacy. With the potential to also acquire the adjacent parcel at 238 E. Mendocino, the possibilities for development or a multi-generational estate are truly limitless. Surrounded by stunning and still intact multi-million-dollar homes, this location combines prestige, tranquility, and unmatched potential. Phase 2 environmental review has already been completed by the Army Corps of Engineers, paving the way for your vision to come to life. The lot once featured a charming 3-bed, 2-bath residence spanning 1,758 sq ft, and still offers a lush landscape of mature, blooming trees and untouched foliage - perfect for crafting a serene retreat. Conveniently located near Altadena's hiking trails, coffee shops, parks, and cultural landmarks, this property blends natural beauty, history, and lifestyle.
