FAQ: DIY Shed Essentials
Do I need a permit for a DIY shed under 100 sq ft?
In 42 U.S. states, sheds under 120 sq ft require no permit, but 18 states mandate foundation inspections. Always check your county's zoning map first—coastal areas often have stricter rules due to wind load requirements.
How do I prevent wood rot in a budget shed?
Apply two coats of vinegar-steel wool solution (1:1 ratio) before assembly—creates natural tannins that repel moisture. Then install a 6" gravel foundation with landscape fabric. Never let wood touch soil directly; use concrete piers.
Can I build a shed on uneven ground?
Yes, but use adjustable foundation blocks. Our tested method: Level the site within 2" using a laser level, then place concrete piers on compacted gravel. For slopes over 6", build terraced foundations with retaining walls—adds $75 but prevents sliding.
