About This Home

As of January 2026

Exceptional opportunity on a large Altadena lot offering significant development and investment potential. The property was affected by high winds during the Eaton fires, resulting in a tree falling onto the front house, which is currently uninhabitable. Notably, the front house underwent a major renovation in 2024, and approved plans are available, providing a valuable head start for rebuilding. According to county planning, the expansive lot is eligible for two 2-story homes, each with its own ADU, allowing for up to 9,000 square feet of total living space. This makes the property an outstanding opportunity for an owner-builder, developer, or investor seeking to maximize value. The rear house is a charming and livable 1923 cottage, featuring 1 bedroom and 1 bathroom, a kitchen, living area, and laundry room. Updates include a renovated bathroom (2019), heat pump system, and a Miele dishwasher—blending vintage character with modern convenience. A finished 2-car garage offers exceptional flexibility and is ideal for a studio, workspace, or creative use. Highlights include a split-system HVAC, polished concrete floors, insulated walls and ceiling, vaulted ceiling, and high north-facing windows that provide beautiful, diffused natural light. Two pairs of French doors open to serene yard views. The sloped roof’s angle and orientation are optimized for future solar panel installation. The property features generous front, middle, and rear garden spaces with mature trees, including avocado, mango, camellia, and bay. The bay trees form a tall, natural hedge, offering privacy and a peaceful setting. A long driveway accommodates parking for up to four vehicles. A rare chance to restore, rebuild, or redevelop a property with strong fundamentals, approved plans, and remarkable long-term potential in a desirable Altadena neighborhood.
