3718 El Sereno Avenue, Altadena, CA 91001

Perched on an elevated corner in a quiet and serene Altadena pocket, this cleared 6,729-sq-ft parcel offers a rare chance to design a home surrounded by mountain charm and community character. Formerly the site of a 3-bed/1-bath cottage with a detached garage, the property now presents open sightlines across the neighborhood and toward the city—embedding long-term value into any future build. With hiking trails, parks, and local conveniences just minutes away, the location balances privacy, tranquility, and everyday ease. On warm LA days, the hillside setting enjoys cooler breezes and a natural sense of retreat, making it an ideal setting for both a dream residence or a high-upside investment. 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: This is a drive-by only listing. Do not enter the property due to current safety protocols. Phases 1 and 2 have been completed.
