Properties offering this much land, privacy, and versatility in such a desirable location are becoming increasingly difficult to find. Welcome to 5605 Archibald Avenue, a unique property combining spacious living, extensive improvements, and exceptional possibilities for the future. The home features numerous upgrades, including copper plumbing, smooth-finish drywall, dual-pane windows, a 200-amp electrical panel, upgraded insulation, and a newer water heater installed in April 2026. All air-conditioning units and ductwork were replaced in 2016, providing additional comfort throughout the home. Inside, you'll appreciate thoughtful details such as cedar-lined closets, marble-top vanities, ceiling fans, and a Jacuzzi-brand tub. The kitchen is equipped for serious cooking and entertaining, featuring professional-grade appliances, including a 48-inch double oven, a professional 30+30 inch refrigerator, and a kitchen island already plumbed for water and power. The property also offers impressive utility and functionality, including an expanded septic system, a 500-gallon owner-owned propane tank, a 220V/30-amp garage outlet, washer and dryer hookups in both the garage and laundry room, and a generous 20-foot-wide RV driveway. Outdoor hot and cold water connections provide additional convenience. But what truly sets this property apart is the land. Finding approximately two acres in on of Rancho Cucamonga's most sought after neighborhoods is an increasingly uncommon opportunity.
