About this calculator
Can I build a shed myself?+
A prefab kit shed on a gravel pad foundation is a very manageable DIY project, often completable in a weekend by one or two people. A stick-built shed from raw lumber is a bigger step up requiring real carpentry skill, and gets significantly harder above roughly 150 sq ft.
Do I need a permit to build a shed?+
It depends heavily on size and your state or local jurisdiction. Many places exempt small sheds (often under 100-200 sq ft) from permitting entirely, but this threshold is set locally in most states — always verify with your city or county building department before building, especially for a larger shed.
Should I use a gravel pad or concrete slab for my shed?+
A gravel pad is cheaper, faster, and DIY-friendly — good for most small to medium sheds. A concrete slab costs more and usually requires a professional pour, but is more durable and often required for larger or more permanent structures, or if you plan to run electrical to the shed.
