Do I need a permit to build a shed?

Most jurisdictions require permits for sheds over 120-200 square feet, or any shed with electrical or plumbing. Always check local building codes.

What is the best foundation for a shed?

For small sheds, concrete blocks or gravel pads work well. For larger sheds, use concrete piers or a continuous concrete slab.

How do I keep my shed dry inside?

Proper roof overhang (6-12 inches), house wrap behind the siding, good ventilation, and a slightly elevated foundation all prevent moisture problems.
