Spanning nearly 3,000 square feet, the residence features a highly functional 7-bedroom, 4-bathroom layout. A key asset is the inclusion of dual primary suites, providing an ideal setup for multi-generational living, long-term guest accommodation, or a private home-office wing. While the property retains its architectural heritage, all major mechanical systems have been comprehensively updated to ensure long-term efficiency and peace of mind. Key improvements include dual HVAC zones, a tankless water heater, updated PEX plumbing, and energy-efficient dual-pane windows throughout. The level, 15,000-square-foot lot provides a rare commodity - completely usable, flat outdoor space. This expansive backyard serves as a versatile blank canvas well-suited for a detached accessory dwelling unit (ADU), pool installation, or custom landscaping. Located in a quiet foothill neighborhood, the property offers immediate access to local mountain hiking trails and historic landmarks, while remaining a brief drive from Old Pasadena and just 15 miles from Downtown Los Angeles. This estate represents a practical, data-backed opportunity for a buyer seeking extensive square footage, updated systems, and premium lot utility.
