10 Things You Can't Store in a Storage Unit

July 25th, 2026

Renting Storage Units is a convenient way to create extra space during a move, renovation, downsizing project, or business expansion. However, not everything belongs in a storage unit. Most storage facilities have rules about prohibited items to help protect customers, staff, and stored belongings. Knowing what cannot be stored before move-in day can save time and help you avoid unnecessary complications.

At El Campo Casitas & Self Storage, located at 5800 Central Ave SW, Ste 1, Albuquerque, NM 87105, customers can choose from a variety of storage unit sizes for household and business belongings. Before packing your unit, it's important to understand which items should stay out of storage and why.

1. Perishable Food

Food items such as fresh produce, meat, dairy products, and baked goods should never be placed in a storage unit. Even packaged foods can attract insects and rodents over time.

If you're storing kitchen supplies, make sure every cabinet, container, and cooler is completely empty before placing it into storage. Cleaning these items thoroughly also helps prevent unwanted odors.

2. Plants

Living plants require sunlight, water, and airflow to survive. A storage unit doesn't provide the environment needed to keep plants healthy, so they will quickly deteriorate if left inside.

If you're moving, consider giving plants to friends or family temporarily or transporting them directly to your new home.

3. Animals or Pets

It may seem obvious, but pets and other animals should never be left inside a storage unit, even for a short period. Storage units are designed for belongings—not living creatures.

Animals require proper care, ventilation, food, and water, none of which can be provided inside a storage unit.

4. Flammable Liquids and Fuels

Gasoline, diesel fuel, kerosene, lighter fluid, propane cylinders, and similar combustible materials should never be stored inside a storage unit.

These products create unnecessary safety risks and are prohibited at virtually all storage facilities. Before storing lawn equipment or other machinery, drain any remaining fuel according to the manufacturer's recommendations.

5. Fireworks and Explosives

Fireworks, ammunition components, explosives, and other hazardous materials should always be stored according to local regulations—not inside a storage unit.

These items present serious safety concerns and are generally prohibited for the protection of everyone at the facility.

6. Hazardous Chemicals

Paint thinners, strong cleaning solvents, pesticides, pool chemicals, and similar hazardous substances require special handling and should not be stored alongside household belongings.

If you're unsure whether a product is appropriate for storage, review the manufacturer's instructions or dispose of it through an approved local program before moving.

7. Wet or Damp Items

Never place furniture, rugs, mattresses, clothing, or cardboard boxes into storage if they're still wet.

Moisture can lead to unpleasant odors and damage stored belongings over time. After cleaning furniture or washing fabrics, allow everything to dry completely before packing your storage unit.

Taking a little extra time beforehand can help keep your belongings in excellent condition throughout the storage period.

8. Unregistered or Inoperable Vehicles

If you're planning to store a vehicle, always confirm the facility's requirements first. Many storage facilities have specific policies regarding vehicle storage, registration, and insurance.

Checking these details before move-in helps ensure you're selecting the right storage solution for your vehicle.

9. Valuable Documents You Need Frequently

Storage units are useful for organizing belongings, but documents you regularly need—such as passports, wills, financial records, medical paperwork, or legal documents—are often better kept somewhere immediately accessible.

If you choose to store important records, place them in clearly labeled, protective containers and make sure you won't need immediate access to them.

10. Anything Illegal

Illegal goods or stolen property should never be stored in a storage unit. Storage facilities operate under rental agreements that require customers to use their units responsibly and in accordance with applicable laws.

Following facility rules helps create a safe storage environment for everyone.

What Should You Store Instead?

While some items are prohibited, storage units are ideal for many household and business belongings. Furniture, moving boxes, seasonal decorations, clothing, office supplies, business inventory, sporting equipment, and household items are all common reasons people rent storage.

Packing your belongings carefully, labeling every box, and creating an inventory can make your storage experience much more organized. Placing frequently used items near the front of the unit also saves time whenever you return.

By understanding what belongs in storage and what doesn't you'll enjoy a smoother move-in process and help protect your belongings throughout your rental.

Store Smarter from Day One

Preparing for storage starts before the first box is loaded. Taking time to remove prohibited items, clean your belongings, and organize everything properly helps ensure a successful storage experience.

Whether you're storing household furniture during a move or creating extra space for your business, following facility guidelines helps make move-in easier while keeping your belongings organized and ready whenever you need them.
