Why Should You Anchor a Shed

  • It protects your financial investments in case of a storm
  • Airborne sheds can be very dangerous
  • Helps to reinforce the integrity of the entire structure
  • Can keep sheds on uneven ground from shifting or moving

The most obvious reason why you should anchor a shed is that it may be required by law. A quick look at the facts makes it obvious why the law may require anchoring for building a shed. During tornadoes or hurricanes, an airborne shed can be a huge hazard. The contents of the shed will also be airborne if the shed gets blown away.

Building a shed or buying one can be a big financial investment. The items you store in the shed could also be of high-value, tools are expensive. You want to protect your financial investments in case of a storm, as well as a lookout for safety concerns. It is unwise to invest in a shed and then not protect it by installing an anchoring system.

Garden sheds, like other structures, are governed by building laws. They must meet a certain standard of safety. Concrete is the best way to securely anchor a shed, but augers can also be used. Depending on the type of shed, anchoring is usually inexpensive and fairly easy to do.

The best anchoring system and the number of anchors needed will depend on the size, weight, and materials of the shed. Smaller garden sheds will require fewer anchors than large garden sheds. The anchors are placed in the four corners of the shed, but some anchoring systems include attaching cords, straps, or other devices which go over the roof of the shed to provide pressure from the top of the structure.

Can I anchor a shed without concrete

You are advised to have some sort of anchoring system in place for your shed, but the good news is you don’t need to have it attached to the concrete. Of course, it will depend on the size of the shed but it’s possible to anchor a shed without concrete.

Just as there are many reasons why you would anchor a shed, there are also many ways you can anchor it. As mentioned, it all depends on the size of your shed and the weather conditions of your local area as to which type of anchoring you’ll need.

Different types of shed anchoring

A simple anchor/auger kit might be adequate for keeping your shed securely on the ground.

Or perhaps using anchor plates to secure your shed to its base or foundation.

If you are going to add a concrete foundation then you may want to consider adding an anchoring system, such as a base post before the concrete sets. Planning ahead in this way will certainly be the best and most secure way to anchor your shed.


Small storage sheds may not require building permits, but the larger ones almost always do. The building permit and other local ordinances may require that the shed be anchored down. Even if it is not required by law in your area, we highly recommend that you be proactive in anchoring the shed in case of high winds or natural disasters.
