If you want to save some space, then you should consider everything about a self-storage facility. Part of that consideration includes what can not be allowed in a self storage center.

What if you’re planning to move out of your current residence, then you probably know how stressful moving is. It takes time, money, effort… and sometimes even emotional stress as well.

But what if I told you that you could avoid all of that hassle by simply renting a storage unit? It may sound too good to be true, but it isn’t.

In fact, it’s quite easy to rent a storage unit and use it for your personal needs. People do that all across the country every day. The best storage rates are often not shown on the internet.

However, storage units are not one size fits all. There are some things that are not allowed to be stored. These can vary from company to company, but when you know all about storage center’s requirements, you find that they have a similar list of restricted items.

In this article, we’re going to share 16 things that you shouldn’t put inside a storage unit or locker.


Self Storage Do’s and Dont’s

Self-Storage facilities are becoming very popular these days. When the economy is doing great or when it’s going slow, storage always seems to keep busy.

Mini storage offers a safe and secure place where you can store your belongings. It also means these are belongings you store yourself without any assistance.

There are several types of storage units available depending upon the size and purpose. Some of them include climate controlled units, units accessible from outdoors, a space for boats, vehicles and trailers, and more.

The units are designed so you can pack lots of boxes into them along with your various possessions. This helps take some of the burden away from the space you need to use at home or in the office.

There are certain things that you can’t put inside a storage unit because the items might get damaged or that they could cause damage to the storage center. Briefly these items include food, liquids, chemicals, flammable materials, batteries and more.

The list of prohibited items that surprises people the most is that these items are also prohibited from storage — and Omaha storage is no different:

  • Furs – precise climate control is needed
  • Tires – these are costly to dispose of
  • Unlicensed or unregistered vehicles, trailers and boats

So if you try to store any of those, be sure to reach out to your storage center for the reason why they’re not accepted.

Now let’s dig a little deeper into what storage centers do not allow.

16 Items Not Allowed In Storage Rooms It’s important to know what is not allowed so you don’t get caught by surprise later.

Here’s Details About Each Restriction


You can’t store fireworks inside a storage unit. This includes sparklers, firecrackers, bottle rockets, Roman candles – you get the idea. The reason why is simple: they contain explosive material and could cause serious injury or death if they explode.


You can’t store explosives inside a storage unit. This would include dynamite, blasting caps, black powder, gunpowder, ammunition, nitroglycerin, TNT, C-4, Semtex, plastic explosives, military ordnance, grenades, mines, bombs, landmines, artillery shells, mortars, rocket launchers, missiles, cluster munitions, nuclear weapons, chemical weapons, biological weapons, radiological weapons, incendiary devices, pyrotechnic devices, and improvised explosive devices (IED). Sometimes people have classic grenades that are supposed to be inert but might not be, so not a good idea to store items like that.

Hazardous Material

Any kind of hazardous material such as chemicals, propane, aerosols, asbestos, lead, mercury, arsenic, cyanide or other dangerous materials don’t belong in a storage unit. Anything that could possibly blow up or cause damage to the storage facility shouldn’t be stored there — as it could hurt someone.


You can’t store weapons inside a storage unit. You can imagine why that is. Items like these can greatly increase liability issues for the storage center. Instead, you should keep all firearms unloaded and locked away at all times and preferably in your nearby possession.

Any kind of illegal material

If you’re planning on holding tobacco products, gambling equipment, stolen property, counterfeit currency, unclothed pictures, human remains, contraband, or any other type of illegal material, you’ll need to find somewhere else to store it.


You can’t store alcohol inside a storage unit. Even if you think you’re going to drink it, you won’t be able to store it. It is against the law to store liquor or beer inside a self-storage facility and it might even be flammable.

If you have a fine wine to store, you may want to talk with storage centers that offer climate controlled storage to see if they will let you store your wine. There are several centers that recognize your value in the fine wine and that will find a way to accommodate your storage need.

Illegal Drugs

You can’t store illegal drugs inside a storage unit. It is against the law for anyone to knowingly possess illegal substances. You also cannot sell or give illegal drugs to someone else. Not only is this illegal, but it also poses a health risk for everyone who works at the facility.


You can’t store food inside a storage unit. There are many reasons why this is bad idea. First off, you never know when someone is going to want to steal your food. Also you run the risk of having rodents or insects get into your food. Then there’s the chance you could end up with spoiled food which might make people sick. Lastly, you might accidentally eat some of the food yourself. Overall it’s just not a good idea.


You can’t store liquids inside a storage unit. Liquids like gasoline, oil, paint thinner, solvents, cleaning supplies, pesticides, herbicides, fertilizers, drain cleaner, antifreeze, motor oil, windshield washer fluid, brake fluids, transmission fluid, engine coolant, radiator fluid, power steering fluid, windshield wiper fluid, windshield wash solution, car wax, window cleaner, floor polish, carpet cleaner, bleach, ammonia, turpentine, nail polish remover, and kerosene are examples of things that should not be stored inside a storage unit. I know that I’ve got several of those item for taking care of the car in my garage — but for storing them in a storage unit it’s not permitted.


You can’t store chemicals inside a storage unit. Chemicals like acids, pool acid, alkalis, caustics, oxidizing agents, reducing agents, corrosives, organic compounds, inorganic compounds, solvents, detergents, bleaches, dyes, stains, paints, varnishes, adhesives, sealants, glues, resins, epoxies, polymers and elastomers are examples of what you can’t store inside a storage unit. I was actually surprised about the pool chemicals but it makes sense. If you have any of those, you will need to find another place to keep them. It’s amazing how many of those items we each have at home — but can’t place into storage. Makes me think… is my garage safe with all this cleaning stuff I have in there?


These include anything that could be easily combustible where it could pose a fire hazard. Just like was mentioned above being anything that could create an explosion. This could include anything that could contaminate the air quality and cause harm the storage building itself.


These most likely would be included above as a hazardous chemical liquid, pesticides are so very commonplace that it’s easy to forget how potent they can be. They’re often used on lawns, gardens, crops, trees, shrubs, flowers, fruits and vegetables. Pesticides are usually applied by spraying, dusting, spreading, dipping, soaking and other methods — so they can come in liquid or powder form. When moving belongings from a garage, its easy to forget that those pesticides are not allowed at the storage center.


Most storage centers do not allow animals inside their units. The reason of course is fairly obvious. For example, imagine if an animal gets loose, it could damage property or even injure someone else. Plus it’s very cruel to subject an animal to certain seasonal conditions.

Animals such as dogs, cats, birds, snakes, lizards, hamsters, gerbils, guinea pigs, rabbits, ferrets, mice, rats, turtles, frogs, fish, reptiles, amphibians, insects, cockroaches, crickets, grasshoppers, beetles, termites, wasps, flies, mosquitoes, fleas, ticks, hornets and others are all strictly prohibited and not allowed inside a storage facility.

Human body parts, blood, body fluids and feces

This is a harder one to talk about. Nobody wants to picture these things, but the storage center doesn’t want to see them either. Human body parts, blood, human blood products, human body fluids and excretions (feces) are all considered biohazardous materials and are therefore not allowed inside a storage unit.

Medical Waste

Similar to the last one mentioned, obvious medical waste includes needles (used needles too), syringes (used syringes), scalpels, bandages (used bandages), gauzes, sponges, cotton balls, swabs, thermometers, IV bags, tubing, bottles, vials, tubes, caps, stoppers, clamps, sutures, dressings. It goes even deeper and includes anything made out of plastic, metal, glass, rubber, paper, wood, cloth, foam, cardboard or leather that has been contaminated with bodily fluids, blood, tissue, pus, urine, saliva, sweat, mucus, breast milk, amniotic fluid, oral rinse, ophthalmic solution, otic solution, parenteral solution, intravenous infusion, intrauterine device, tampon applicator, contraceptive sponge, cervical cap, diaphragm cup, condom, dental dam — I think you get the idea. That’s a long list but I guess someone in the past has tried to store something like these items in the list.

Unsafe and Hazardous Waste

In addition to all those hazardous items mentioned above, this goes further by including toxic waste, radioactive waste, and even electronic waste. These types of waste are also not allowed inside a storage locker.


If it’s liquid, living, food or flammable, it’s best not to store it. For questionable items, check with your storage center for advice.

Other Items

In addition to the above list, there are other items that you should not store inside a storage unit that isn’t climate controlled. These items include furniture, appliances, electronics, musical instruments, treasured heirlooms, high value items, important documents and more. We have more information about that here.



It’s very important to know what type of storage unit you need before you start looking for one.

Fortunately, there are many different types of storage facilities available today, especially in the Omaha area.
