About This Home

6495 Barnacle Court

A rare Boulder opportunity — own an entire side-by-side duplex in unincorporated Boulder County, just 10 minutes from downtown Boulder and CU. Each unit backs directly to open space and the trail system, with private yards, covered parking, and separate utilities for true independence. One side has been fully renovated with new furnace, water heater, windows, and premium finishes throughout the entire unit. The other side offers a clean canvas ready for your custom updates or value-add improvements. New roof and all new windows throughout the entire building. Both units are vacant, providing maximum flexibility — live in one and rent the other, lease both, or expand by finishing each basement to create 3 bed / 3 bath layouts. A property that blends Boulder lifestyle, privacy, and investment potential — a combination that rarely becomes available.
