Spacious California ranch-style home located in one of Glendora's desirable foothill neighborhoods, set on an expansive 15,600 sq. ft. lot with scenic foothill and mountain views. This well-maintained residence offers 4 bedrooms and 2 bathrooms with approximately 1,759 square feet of living space, plus an additional approximately 400 sq. ft. finished bonus room currently used as a family room, creating roughly 2,200 sq. ft. of functional living area. The bonus room seamlessly integrates with the main living space and offers flexible use for a recreation room, home office, gym, or additional living area; the space is not included in the official square footage. With its wide frontage, large lot, and resort-style backyard, the property offers a rare mini-estate feel and true indoor-outdoor Southern California living rarely found in this established Glendora neighborhood. Recent improvements include brand-new windows, updated plumbing, and a new sewer line to the street installed less than two years ago. The standout feature is the private backyard oasis, featuring a large in-ground pool finished with custom PebbleTec less than 18 months old, spacious patio areas, gazebo seating area, and generous lawn space ideal for entertaining, gatherings, and year-round outdoor enjoyment. The backyard has been completely remodeled within the last 36 months, including upgraded concrete, planters, and landscaping that enhance the outdoor living space. The oversized driveway provides ample parking with potential RV access, and the home is conveniently located near parks, hiking trails, and within the highly regarded Glendora Unified School District.
