What Should You Never Store in a Self Storage Unit?
What Should You Never Store in a Self Storage Unit?
Self storage is a convenient solution when you need extra space, are moving, downsizing, renovating, or simply trying to get organized. But a storage unit is not designed to hold everything.
After owning and operating self storage facilities, we have seen firsthand that some items create unnecessary risks for customers, their belongings, and even other tenants. Many storage problems happen because people simply do not realize that certain items should never be placed inside a storage unit.
Before storing anything, ask yourself three simple questions:
- Could this attract pests?
- Could this start a fire?
- Could this leak, spill, or damage other belongings?
If the answer is yes to any of those questions, it probably does not belong in a self storage unit.
Food and Anything That Attracts Pests
One of the most common mistakes we see is people storing items that seem harmless but create an invitation for pests.
Food, bird seed, pet food, and other items that contain organic materials should never be stored in a self storage unit. Even sealed bags can attract rodents and other pests because they are drawn to the scent and will find ways to access food sources.
Bird seed is a great example. Many people think, “It’s just a bag of seed; it will be fine sitting in the corner.” Unfortunately, that bag can quickly become a food source for rodents, creating a problem not only for the customer storing it but also for neighboring units.
A storage unit should protect your belongings—not become a place where pests are encouraged to move in.
Chemicals, Cleaning Products, and Liquids
Another category that requires caution is chemicals and liquid products.
We once had a cleaning company store liquid cleaning concentrates in a storage unit. Over time, those products degraded and lost their effectiveness. The customer expected the products to remain usable, but storage conditions were not ideal for preserving their quality.
Cleaning products, chemicals, and other liquids can also create additional concerns if they leak, spill, or react with other materials nearby.
Items such as these should generally not be stored in a self storage unit:
- Cleaning chemicals
- Paints and solvents
- Fertilizers
- Pesticides
- Pool chemicals
- Automotive fluids
- Other hazardous liquids
Even when a product seems stable, long-term storage can change how it performs and increase the chance of damage.
Flammable Items and Fire Hazards
Anything that could contribute to a fire should stay out of a storage unit.
Storage facilities contain many enclosed spaces close together, and a fire can quickly affect far more than one customer’s belongings. For the safety of everyone, avoid storing items such as:
- Gasoline or fuel
- Propane tanks
- Fireworks
- Charcoal
- Flammable chemicals
- Oil-based products
- Other combustible materials
A good rule of thumb is this: if you would not feel comfortable keeping it inside your home because of fire risk, it probably does not belong in a storage unit either.
Irreplaceable Family Heirlooms
One of the most important pieces of advice we give customers is this:
If something is truly irreplaceable, think carefully before storing it.
A storage unit can be a great place for many belongings, but items with deep sentimental value deserve extra consideration. Family photographs, historical documents, and one-of-a-kind heirlooms may be impossible to replace if something unexpected happens.
Ask yourself:
“Could I replace this item if it was damaged or destroyed?”
If the answer is no, consider whether a storage unit is the best location.
Climate Controlled Does Not Mean Temperature Controlled Like Your Home
A common misconception about self storage is that climate-controlled units are the same as keeping items inside your house with the air conditioning running.
That is not the case.
Climate-controlled storage generally means the unit maintains a wider range of temperatures and humidity levels compared to traditional outdoor storage. It does not necessarily mean the space will always feel like a comfortable room in your home.
Climate-controlled storage can provide added protection for certain belongings, but customers should still understand its limitations. It is not a guarantee that every item will be preserved perfectly forever.
Your Homeowner’s Insurance May Not Cover Your Storage Unit
Another misunderstanding we frequently see is customers assuming their homeowner’s or renter’s insurance automatically covers everything inside their storage unit.
In many cases, it does not.
Customers should check their insurance policy carefully and understand what coverage applies. Some storage facilities offer insurance options specifically designed for stored belongings, while others may require customers to obtain their own coverage.
Do not wait until something happens to find out your belongings were not protected.
Questions to Ask Before Putting Anything Into Storage
Before moving an item into a storage unit, take a few seconds to evaluate the risks.
Ask:
- Could this attract insects or rodents?
- Could this leak or spill?
- Could this create a fire hazard?
- Would I be devastated if this was damaged?
- Does this item require special temperature or humidity conditions?
These simple questions can prevent expensive mistakes and protect both your belongings and the belongings of other customers.
Store Smart and Protect Your Belongings
Self storage is an excellent tool when used correctly. It gives people flexibility during life transitions and provides valuable space when homes, businesses, and garages are full.
The best storage customers are the ones who think ahead. They avoid storing anything that could create a problem, properly prepare their belongings, and understand that a storage unit is a secure space—not a replacement for every type of storage environment.
Our simple rule is this:
If it is an irreplaceable family heirloom, could start a fire, could spill, or could attract pests, do not store it.
Taking a few minutes to make the right decision before moving items into storage can save you a lot of frustration later.
