Does this include labor?
No, this is a DIY estimate for materials only. Labor would significantly increase the cost.
Typically, costs break down as: Foundation (10-15%), Framing & Sheathing (40-50%), Roofing (15-20%), Siding & Trim (20-25%).
Building it yourself saves 40-50% compared to buying a pre-built shed or hiring a contractor. Potential labor savings: $3360 - $5040.
For a 120.0 sq ft shed, check local codes. Many areas require a permit for structures over 100-120 sq ft.
