How much does it cost to build a shed?

Most of the cost tracks the floor, wall and roof area, so size drives the price.

  1. Choose the size. Set width, length and wall height.
  2. Pick the foundation. Skids and blocks cost less than a slab.
  3. Choose finishes. Siding and roofing swing the total.
  4. Add openings. A door and windows add a fixed amount.
  5. Set local prices. Adjust against the national assumption for your area.

Typical materials cost by size

Frequently asked questions

Is it cheaper to build or buy a shed?

Building usually saves on materials if your time is free, but kit prices vary widely. Get a local kit quote to compare.

How much is a 10x12 shed to build?

Using the assumptions here, materials land around $4,000 before local adjustments.

Do I need a permit for a shed?

Many towns exempt small sheds, often up to 120 or 200 sq ft, but setbacks still apply. Check with your building department.

What foundation is cheapest?

Concrete blocks or skids on gravel usually cost the least. Slabs cost the most and last the longest.

Does this include labor?

No. It is materials only.
