How do you Build a 12×20 Shed Floor on a Skid?

Below is a step-by-step guide to ensure the easy and proper construction of your 12×20 shed floor on a skid. 

#1. Gather your Materials 

The materials you’ll need are as follows;

  • Wood screws and exterior grade screws
  • Joist hangers
  • Framing nails
  • Pressure-treated lumber
  • Pressure-treated plywood

#2. Layout the Area with Deck Block

After every 4-6 feet, lay a deck block to have equal distance from each other. Next, lay 2×6 boards in the grooves of the deck blocks.

Laying the wood in the grooves of the deck blocks gives the ground level and the floor frame stable support. Tap down and dig. 

#3. Mark the Two-Band Boards

From the length and width of your 12×20 shed, ready two joists, and two rim joists. Ensure the rim joists’ length is the same as the shed’s length.

Cut your pressure-treated lumber with a chop saw according to your measurements. With a speed square, mark where your cuts need to be. Using a wood preservative, seal the cut ends of your lumber.

#4. Assemble the Outer Frame

Put the framing together and use framing nails to hold the ends. Join all four boards together to form a box. 

#5. Square the Floor Frame Appropriately

Use a measuring tape to ensure you have an appropriate box with either every two sides equal or all four sides equal. Do not hesitate to move your blocks to make the perfect square. 

#6. Anchor the Floor Frame

Using concrete piers, anchor your frame to keep it grounded. First, pick the areas where your anchors will be.

One anchor for every corner is perfect. Dig holes in those areas, fix the fiber tubules, add concrete, install the brackets and fix with anchors to the foundation. 

#7. Place Rim Joists

Using a speed square, cut out rim joists to use. Fix the joists into the hangers and use a hammer to tap them down. Use the Simpson screws to attach joist hangers to the frame.

#8. Layout the Sheeting

Cut your plywood according to your desired length and width, which is 12×20. Ensure it is even, then you screw it down into the joists. Use two screws on each plywood at the edges where two pieces of the wood meet.

Do I Need a Permit for a Shed on Skids?

One advantage of having your shed on skids is that it doesn’t require a permit.

It doesn’t require a permit because you cannot class it as a permanent structure since you can move the shed from place to place, while other sheds with foundations other than the skid foundations require permits because they are permanent structures.

Although, it is better to call your local building inspector’s office to determine whether you need a permit.

A few areas may insist on you having a permit. Other areas insist that permits are necessary unless your shed is more than 10sq meters, where a permit is not essential.

That is why you should try to determine if a permit is necessary for your location or not. 

It would be best if you tried contacting the local building inspector’s office as much as possible before you begin to construct your shed.

The inspectors of areas where permits are required are very strict with the rules. The officers may take actions like asking you to demolish your shed if you don’t have a permit or cease work on your shed and pay a fine of $600 or more.

Can Thinset be Used in a 12×20 Shed on Skids?

Thinset waterproof can be used in a 12×20 shed on skids. It is a versatile adhesive that ensures a strong bond between various materials, such as tiles and concrete. By using thinset waterproof, you can securely attach tiles to the shed floors or walls, providing a durable and water-resistant surface.

Does a 12×20 Shed need a Foundation?

A shed of 12×20 would require a stable foundation to stay balanced. Typically, any shed larger than 6×8 or 8×8 requires a foundation.

Building the shed foundation is essential as it allows proper water drainage, prevents premature weathering, and prevents damage to your shed.

Even if the shed is 6×8 or 8×8, getting a foundation for your shed should be your priority.

A good foundation is essential because sheds of that size are still very much prone to fall from the pressure of high winds or rainfall.

However, it is better to place all large or small sheds for structure and ventilation purposes.

A 12×20 shed without a foundation would hardly stand and could easily fall from the pressure exerted on it by strong winds. This fall is worse when you make your shed with plastic or light metal materials. 

While constructing your 12×20 sized shed, building the shed foundation allows you to have the confidence of a long-lasting shed.

The best part is that you don’t need to call a service department to help build the shed foundation. 

The process is relatively easy, and with suitable materials, a good guide, and a friend or two to help, you should have your foundation set in just one day. 


Building a 12×20 shed on skids has many advantages like easy movement from place to place, no permits necessary, a solid and well-ventilated structure, and many more.

A skid foundation is easy to construct and requires very little help. Having your 12×20 shed on skids is a perfect option you should consider while constructing your shed.
