How Much Does It Cost to Build a Shed in 2026?
Updated 2026-10-14. All figures were checked on that date.
Short answer: a typical 10×12 site-built wood shed on a gravel pad costs about $5,000–$9,000 installed (EstimationPro AI). Building it yourself, the materials alone for the same shed run about $1,800–$3,200 (CalcSummit, citing RSMeans 2026 data). Get your own number with the shed calculator.

Add-ons people forget
- Electrical: $2,600–$4,300 to run power (ProjectCostPro, as of 2026-10-14).
- Permits: many jurisdictions exempt small sheds, often up to about 120 sq ft. Check your county before you buy, because the threshold varies.
- Delivery and site access: pre-built sheds need a clear path for the truck or a shed mule.
Why the sources disagree
These sources don't define "shed" the same way. Some quote the kit price, others the installed price, and some include the foundation. That is why one site can say $3,000 and another $13,000 for a 10×12. A delivered pre-built vinyl 10×12 runs $7,665–$13,401 according to ProjectCostPro. Before comparing quotes, check whether they include the foundation, labor, delivery and permits.
How to spend less
- Pick gravel over a slab unless code or use (vehicles, heavy machines) demands concrete.
- Stick to sizes that work with 4×8 sheet goods (8×10, 8×12, 12×16) to cut waste.
- Price lumber yourself. See where to buy cheap lumber, and check the lumber index to see whether prices are trending up or down.
