Can You DIY a Storage Shed?
A shed kit is one of the friendliest DIY projects available — the lumber is pre-cut, the instructions are designed for homeowners, and the only specialized skill is reading a plan and keeping things square. A custom-built shed requires more carpentry knowledge but is still well within reach for most DIYers.
What You'll Need
Skills
- •Basic carpentry — drill, circular saw, level
- •Ability to follow detailed instructions (kit) or a simple building plan (custom)
- •Ideally have a helper for wall-raising day
Tools
- •Circular saw or miter saw
- •Drill/driver
- •Level — 4-foot and torpedo
- •Speed square
- •Tape measure and chalk line
- •Framing nailer and compressor (speeds things up significantly)
- •Ladder
Step-by-Step Overview
Level the ground and install your foundation — gravel pad, concrete blocks, pressure-treated skids, or a concrete slab. The foundation must be level and square before anything else.
Build the floor frame from pressure-treated lumber and install plywood decking. Check for square by measuring diagonals — they must be equal.
Frame each wall flat on the floor, then raise and brace them. Start with two opposing walls, then fill in the sides. Brace each wall plumb before moving to the next.
Attach plywood or OSB sheathing to the walls before raising (kit) or after (custom). Sheathing adds rigidity to the structure.
Cut and install rafters or trusses. Install ridge board, barge rafters, and fascia. Add plywood decking, felt underlayment, and shingles.
Install the door frame, hang the door on hinges, and add any windows. Caulk all exterior joints against moisture.
Add siding, trim, and paint or stain. Install interior shelving, pegboards, or organizers as needed.
Potential Savings
For a typical 120 sq ft storage shed at the national midrange cost of $3,120, doing it yourself could save roughly $936–$1,560 in labor costs. Materials remain similar either way.
Actual savings depend on your region, skill level, and whether you need to rent specialized equipment.
Pro Tips
- Spend extra time getting the floor perfectly level and square — every problem in the build traces back to this step
- Pre-prime all lumber before assembly, especially the bottom plate and any exposed end grain
- Add an overhang of at least 12" on all sides to protect the walls from rain
- Install the door hardware before hanging the door — it's much easier on a workbench
Watch Out For
- ⚠Check local zoning — sheds often require a permit above 120–200 sq ft, and there are setback rules from property lines
- ⚠Anchor the shed to the foundation — an unanchored shed can tip over or shift in high winds
When to Call a Pro Instead
- →Sheds over 300 sq ft that require full structural engineering and permits
- →Sites with significant slope that require a complex foundation
- →Any electrical work inside the shed (hire a licensed electrician)
