Shed Foundation Options You Can Use

Having a sturdy shed foundation that's built right is so important for the life of your shed. If not done properly, building your new shed will be a struggle. You will probably encounter everything from walls not lining up to roof sheeting not fitting properly.

Down the road there is also a likely chance that you will experience things like your shed doors not closing properly, windows not opening, and leaks from your roof, just to mention a few!

Your Shed Foundation Can Be One of The Following:

Concrete shed floor.

Wooden shed floor with concrete anchors.

Wooden shed floor on blocks or concrete piers.

Wooden shed floor on compacted gravel base.

Concrete Shed Floor

Concrete Shed Floor/Foundation

This foundation option is one of the best, but also the most expensive. Learn more about using the concrete option here.

Shed Foundation With Concrete Anchors

Wooden Shed Floor w/Concrete Anchors

One of the most widely accepted methods is building a wooden shed floor and anchoring it down with concrete anchors. Although the concrete shed floor is probably the best foundation option you can use, it is also the most expensive.

Building Codes and Shed Foundations

In the greater Dayton area where I build sheds, the most widely accepted method approved by local building inspectors when building a wooden shed floor is to have the concrete floor anchors shown above. This method not only helps prevent shifting, but it helps to anchor your shed down in heavy winds. Of course hurricane or tornado force winds can blow any shed over, but for normal everyday weather conditions this option is widely accepted across the country. Sometimes 2 anchors caddy corner are acceptable, but I almost always went with an anchor in each corner.

Wooden Shed Floor On Blocks

Wooden Shed Floor On Gravel Base

Wooden Shed Floor On Gravel Foundation

Another option is building your shed floor on a compacted gravel base. Here's more information if you are considering this option.

If you have the opportunity to purchase one of my shed plans, you will quickly find out that my favorite of all shed foundations is the wooden floor built on 4x4 or 4x6 treated skids which are anchored to the ground with treated 4x4 posts/piers sunk in concrete. Out of the 10 or so county's around where I live, and purchased a building permit, this was the required method of anchoring a wooden shed floor.

Here's more information you can use to build your shed floor.
