Prime corner lot with exceptional frontage on two streets offering unbeatable design flexibility, multiple street access points, possibility of extra parking space and extended visual footprint (back on market due to buyer non-performance). Build your dream home and ADU (up to 1,200 sq f) on this flat, usable parcel with wraparound yard space and maximum curb appeal. Side-street access allows for multiple driveway and garage placement options, where the main house and the ADU enjoy separate driveways and entrances, increasing privacy for both homes. This corner rectangular lot measures 5,353 sq ft (40 ft wide x 135 ft deep approx. at its longest side per title), Zoning LCR175 and is located in one of Altadena's most sought-after neighborhoods- Janes Village in proximity to Alta Loma Park. Set against the stunning backdrop of the San Gabriel Mountains, this lot offers breathtaking views of the surrounding mountains. The property has completed Phase 1 (Hazardous Waste Removal by the EPA) and has also completed Phase 2 (Structural Debris Removal by the Army Corps of Engineers). Additional cleanup is complete and ready for LA County's expedited permitting rebuilding process allowing building a 10% larger home with a 2-car detached garage + a detached ADU (up to 1,200 sq feet). The property is being sold as land only. Buyers should independently verify all zoning, permitting, and rebuilding requirements with Los Angeles County. The property is being sold in as-is condition. Utilities and sewer services are previously connected; buyers are to verify the status with local providers.
