What Should You Not Put In Self-storage?

Self-storage has been one of the fastest-growing sectors of real estate for a good reason. After all, a storage unit can temporarily solve several problematic situations for homeowners and renters. A storage unit is like having a spacious spare room to store items – for a monthly fee. In order for self-storage to work out successfully, it is important that you follow some basic and common sense rules. These self-storage rules exist for the tenants’ and the facility’s safety. The number one rule is that there are certain things you are not allowed to put into storage. To help you, here are some of the top things you should never put in a storage unit.

What Should You Not Put In Self-storage?


Food items, including pet food, should by no means be kept in a storage unit. If you leave food in an enclosed space for too long, it can start to rot and smell, attracting insects and rodents alike. In turn, your uninvited storage guests can damage the rest of your storage items by chewing them or even setting up a home in them.


Plants are another obvious non-storage choice, even if it is a climate-controlled storage unit. In order to grow, plants need water, light, and fresh air. As we are sure you know, all of these essentials cannot be found in a storage unit. If you can’t take your plants with you to your new home, give them to friends for safekeeping, or give them away.

Illegal/Stolen items

Stolen and illegal items should be a no-brainer when it comes to items you should not put in a self-storage unit. Also, do not let other people keep items in your storage unit that you are renting. If the facility manager suspects that something illegal is happening, the storage company will contact local authorities for further investigation. If you are renting a storage unit, you assume responsibility for all items, including firearms and ammunition.

Hazardous materials

It is no surprise that hazardous materials are on the restricted items list. By definition, anything that can create substantial damage if opened or spilled is considered a hazardous material. Corrosive, explosive, or flammable materials are strictly forbidden in your storage unit. Hazardous materials are a serious health risk and can cause damage to the facility or items in other units, not just your own.

A few examples of hazardous materials you should avoid putting in storage include:

  • Aerosol cans
  • Acids
  • Weed killers
  • Car batteries
  • Fireworks
  • Charcoal

Other items that you might not have thought about are yard equipment or anything that might still contain fuel. For example, lawnmowers and generators. Note that you may store your lawnmower or generator after draining the fuel.

Wet or scented items

Strongly scented items can attract pests or rodents which can ruin items in storage. Also, damp items will start to produce mold or mildew and spread bacteria in a storage unit. If you store wet items in your storage unit, mildew is likely to damage some, if not all of your possessions.

Valued items

Lastly, don’t keep money or sentimental items in your storage unit. While your storage facility might have exceptional security, it’s not worth the risk of losing your valuable items. Instead, keep valuable items with you, or give them to a trusted family member or friend.
