WIth the peaceful backdrop of Altadena's western foothills in the distance, this West Altadena lot presents an opportunity for builders and visionaries alike. Zoned for a duplex, the property opens the door to multiple development possibilities--whether you choose to build two units, a main home with an ADU, or restore the charm of what once stood here. Previously the site of a 4-bedroom, 2-bathroom home at 1,880 square feet of living space, the lot is now a blank canvas following the unfortunate events of the Eaton Canyon Fire. This location blends tranquility with community charm. The generous lot size and duplex zoning create potential for income-generating or multigenerational living. This is a unique chance to build something lasting in one of the area's most established neighborhoods. This as-is sale requires the buyer to conduct their own due diligence regarding future building requirements, including consultation with LA County and relevant agencies for site clearance, hazardous material removal, and environmental remediation. The property previously had access to all utilities, but the buyer must verify restoration requirements. Please Note: Phase 1 and Phase 2 of property clean up has been completed.
