Situated in one of Altadena’s most desirable neighborhoods, this lot offers a rare opportunity to build your dream home on a quiet street, surrounded by intact neighboring homes. Located in the heart of Altadena, 1137 E Mariposa provides convenient access to the community’s most treasured landmarks: the country club, library, golf course, Christmas Tree Lane, and Mariposa Junction. It’s also just minutes from popular hiking trails and all that neighboring Pasadena has to offer. The backyard features original hardscape elements, including a decorative tile pool, separate in-ground jacuzzi, spacious patio, and basketball court. The garden that once surrounded the pool was home to a variety of plants, many of which remain today, including a mature palm and plumeria tree. Set at the end of a shared driveway, the lot offers a private and peaceful atmosphere with a strong sense of seclusion. This was once the site of a mid-century, 4 bedroom, 3 bath home with 2,410 square feet of living space on an 8,040-square-foot lot. With Phase 2 debris removal complete, the site is cleared and ready for its next chapter. Currently, Altadena Community Standards allow for a gross structural area of up to 3,010 square feet. This limit does not include an additional allocation for a garage or ADU. The property is being sold as land only.
