About this home

Nestled in one of North San Gabriel’s most desirable neighborhoods, this charming duplex offers an exceptional opportunity for owner-occupants, multi-generational living, or investors. Featuring two similar floor plans situated back-to-back, the property provides excellent privacy while maximizing functionality and future potential. Lovingly maintained and extensively updated by the current owners for family use, this duplex was thoughtfully renovated for family occupancy rather than as a rental property, resulting in quality upgrades and a warm, comfortable living environment. Both residences showcase numerous improvements, including a new layer of roofing, copper plumbing, upgraded electrical panel, and dual-pane windows, remodeled kitchens, updated bathrooms, new flooring, fresh interior paint, and newer air conditioning. The thoughtfully designed drought-tolerant front landscaping offers attractive curb appeal while reducing water consumption, while mature hedges provide a wonderful sense of privacy. One unit is currently tenant occupied, while the second unit has been owner/family occupied, offering flexibility for immediate occupancy or rental income. The rear of the property features two detached single-car garages along with additional parking, providing convenient access for both residences. Beyond its current appeal, the property also offers exciting possibilities for future customization. The existing layout may provide an opportunity to reconfigure one or both units into a three-bedroom floor plan. The property may also offer ADU potential, providing additional flexibility for future expansion. Ideally located in the highly sought-after North San Gabriel neighborhood, this property offers convenient access to shopping, dining, parks, schools, and major transportation routes. Whether you’re looking for a move-in-ready home with rental income, a multi-generational living opportunity, or a long-term investment, this versatile duplex is a rare find.
