Location! Location! Location! This prime 12,012 sq ft lot presents a rare opportunity to build in one of Altadena's most sought-after neighborhoods. Subject to change-R3, the property offers incredible development potential-including multi-units with additional ADUs-making it ideal for investors or builders looking to maximize long-term value. 2252 & 2246 Glenrose Ave for Sale! Owned by the same seller for over 38 years, the property has appreciated significantly and previously generated a strong annual scheduled gross income of $72,000. Conveniently located just 7-10 minutes from iconic landmarks such as Hahamongna Watershed Park, the Rose Bowl Stadium, the Jet Propulsion Laboratory (JPL/NASA), and quick access to the 210 Freeway-this location is a true gem.

This makes it a prime candidate for a smart, strategic development project. Sold As-Is - Buyer to conduct all due diligence. Buyers are strongly encouraged to independently verify zoning, development prospects, and required remediation with Los Angeles County. Drive-by Only - Please Do Not Enter The Property.
