Nestled on one of Altadena's more desirable streets, 50 Marathon is a gem waiting to be transformed. This neighborhood radiates charm and community spirit, offering the perfect backdrop for your dream project. The expansive 9,645-square-foot flat, rectangular lot is a rare find, brimming with potential to bring your vision to life. Set against the stunning backdrop of the San Gabriel Mountains, the location is a gateway to outdoor adventures, with parks, scenic hiking trails, and an eclectic mix of shops and restaurants just moments away. This isn't just a piece of land it's a chance to create something truly unique in a neighborhood steeped in history and inspiration. In this vibrant community, some residents are revitalizing existing homes, while others are starting fresh, contributing to the area's enduring charm. Conveniently located just minutes from Pasadena and with easy access to nearby freeways, 50 Marathon combines a tranquil setting with unbeatable convenience. The property was once home to a single-story, three-bedroom, one-bath house with a large, detached garage, but it has been cleared with both Phase 1 and Phase 2 debris removal completed. It's now a blank canvas, ready for you to make your mark. Offered as land only, 50 Marathon is your opportunity to craft an extraordinary future in a truly special place.
