Keep in mind this doesn’t include the time to complete the design, obtain permits, and install the drywall on the framing. On average, fully finishing a basement takes an average of 45 days.

This entails pushing back the existing rear or side of the closet, simply moving the wall into either an adjacent room or unused space. For ground-floor closets, this could even be extended to the exterior of the home, but that has its own complications.
