Nestled in North Altadena, 3349 Tonia Avenue occupies a flat, 7,560-square-foot lot with open views of the San Gabriel Mountains to the north. A fruiting avocado tree, tended for decades, still stands, along with a professionally designed stone pond that adds a quiet focal point to the property. The location offers easy access to Farnsworth Park, Loma Alta Park, and the nearby network of hiking trails that wind through the foothills. The adjacent property at 3339 Tonia Avenue is also available for sale, presenting a rare opportunity to own two side-by-side parcels in this desirable location. This was once the site of a three-bedroom, two-bathroom home with 1,071 square feet of living space and a 400 square foot detached garage with a 209 square foot studio. With Phase 2 debris removal complete, the site is cleared and ready for what comes next. The property is being sold as land only.
