Do I need a permit for a shed?

Many jurisdictions exempt small sheds under a floor-area threshold, but setbacks and height limits usually still apply. The permit checklist shows the rules commonly attached to your address so you know what to ask about.

Skids or a concrete slab?

Gravel and skids are cheaper and movable; a slab is better for heavy equipment and long-term storage. The estimate updates the foundation materials for whichever you pick.

Does the takeoff include siding and roofing?

Yes — sheathing, siding, underlayment, roofing and trim are all counted from your wall and roof areas with a waste allowance.

Are the material costs accurate for my area?

Costs are regional estimates only, indexed by ZIP against national material averages. Always confirm current prices with your supplier before buying — the numbers here are for planning and budgeting, not a quote.

Do I need to confirm my measurements first?

Yes. The calculator asks you to verify key dimensions before it will produce material, cut, or shopping lists, because a single mistyped dimension changes every quantity downstream.
