Are There Things I Can’t Store in a Rented Storage Unit?

You should check with the storage rental company to list materials and items you cannot store in your rented storage unit.  The rental contract usually lists what you can and cannot store in your unit.  Overall, the storage unit industry prohibits the following items and materials.

  • Flammable or combustible materials.  These materials can include some common household cleaners.  Spray paint is one of the most common items that rental companies forbid.

The rental contract usually lists what you can and cannot store in your unit. 
  • Hazardous materials.  If the material has a hazardous substance label, you shouldn’t store the material in your storage unit.
  • Anything that will attract pests doesn’t go to a storage unit.  Never put food items in your storage unit or anything else that will attract rodents or insects.  This includes pet food.
  • In a non-climate controlled unit, many items may mold or mildew.  These items can include fabric, such as clothing or bedding materials.  You should take steps to protect any of these items if you put them into your rental storage unit.
  • Don’t take your houseplants or anything else alive to your storage unit.  Practice a little common sense.

What does Climate Controlled Storage Mean?

Unfortunately, there is no industry standard on what is required to advertise climate-controlled storage.  In general climate-controlled storage is storage areas that temperature controlled.  Climate controlled storage provides a more stable environment for your stored goods.

However, without clear industry standards on what constitutes climate-controlled storage, there are wide variations in what you may find.   In some areas, climate-control is nothing more than an additional doorway between your unit and the outside.

Ask the Right Questions

Before you rent a climate-controlled storage unit, ask the right questions about what the climate-control provides.

  • Is the building heated and cooled to control the interior temperatures?
  • Do the doors seal adequately to keep out dust and moisture?
  • Are the individual units sealed or do they share a common opening with other units?
  • Is the unit insulated, especially the roof?

Expect to Pay More

Across the U.S, true climate-controlled storage units cost between 25 percent and 50 percent more than a standard unit without climate control.  Climate-controlled storage units are more expensive to build and more expensive to operate than non-climate controlled units.

Don’t Forget to Protect Your Valuables

If you read the contract with the storage rental company, you will learn that the rental company does not provide any insurance coverage for your valuables.  Many rental companies require you to prove that you have insurance on your stored valuable before they rent you a unit.

If your rental company does not offer insurance coverage for your valuables, consider getting an insurance on your own.

Be wary of any rental company that offers to sell you property insurance as part of the contract.   In most instances, the price for this coverage is inflated.  You can find better deals on property insurance coverage through a private insurance provider.

In some states, you may add an insurance rider to your homeowner or rental property insurance policy to cover anything you store in a rented storage unit.  These policies are usually much more economical than buying the same coverage through the rental company.

Making the Move

There are many questions to be answered and considerations at hand before you make a move with your extra stuff to a rented storage unit.  Doing a little pre-move planning can save you money and frustration in the long run.
