About This Lot
Set along a quiet, established street in the foothills of Altadena, this approximately 9,700 sq ft lot presents a rare opportunity to rebuild in one of the area's most character-rich neighborhoods.The site offers a level, rectangular footprint. This property now stands as a blank canvasoffering buyers the chance to design and build a modern home tailored to today's lifestyle while contributing to the thoughtful revitalization of this beloved community. Located just minutes from the Altadena foothills and with easy access to Pasadena, the property benefits from a setting known for its natural beauty and proximity to hiking trails and local amenities. The lot's zoning (LCR175) supports residential development, and like many properties in the area, may offer potential for expanded square footage, ADU configuration, or a contemporary reimagining of the original footprint (buyer to verify). Prior to the fire there were three structures on the property with water running to the main house and guest house. Phase 1 and 2 clearance completed.
