What Items Should Never Be Stored in a Storage Unit
What Not to Store in a Storage Unit
Many renters don’t realize that storage facilities come with a strict storage restriction list, and violating it can lead to serious consequences. These include unit termination, legal liability, or worse, a safety hazard that puts other renters at risk. So, before you start loading boxes, here’s a clear breakdown of what not to store in a storage unit.
1. Hazardous and Flammable Materials
This is the number-one category on every facility’s list of banned storage items. Flammable items storage rules exist because temperature changes inside a unit can cause pressure to build up in sealed containers, increasing the risk of leaks, fires, or explosions.
Prohibited items include gasoline, kerosene, motor oil, propane tanks, fuel canisters, paint, paint thinner, varnish, aerosol cans, cleaning chemicals, fertilizer, and fireworks. Following storage rules also extends to power equipment. Always drain fuel from lawn mowers, chainsaws, or snow blowers before storing them. Dispose of paints and solvents through a local hazardous waste program.
If you’re ever unsure whether something qualifies as hazardous, check the label. Anything marked “flammable,” “explosive,” or “reactive” stays out of the unit.
2. Perishable Food and Organic Items
Food storage restrictions are one of the most commonly overlooked storage unit guidelines. Even airtight containers attract rodents and insects over time. Once pests find their way in, the damage can spread quickly to neighboring units. And it’s not just fresh food causing problems. Canned goods, dry pet food, sealed snack bags, and bottled drinks all fall under food storage restrictions.
Avoid storing fresh, canned, or packaged food of any kind. Never store pet food, animal treats, seeds, soil, or potted plants. If you’re storing kitchen appliances or cookware, clean them thoroughly first. Wipe down every surface, vacuum out any crumbs, and use a mild disinfectant. One forgotten food wrapper can trigger an infestation across an entire facility.
3. Living Things, Pets, and Plants
No living creature belongs in a storage unit. Storage units aren’t designed or equipped to support living things, and keeping animals inside violates both safety codes and humane standards. The same applies to plants. Without sunlight and proper airflow, plants will wilt quickly. Soil and seeds can harbor mold and bacteria, creating conditions that damage everything around them.
4. Valuable Documents and Irreplaceable Items
A storage unit offers security, but not the kind designed to protect your most critical belongings. Think of it like a garage: safe for furniture and seasonal items, but not for irreplaceable items.
Prohibited and high-risk items include birth certificates, passports, wills, legal documents, tax records, financial statements, jewelry, precious metals, rare collectibles, cash, checkbooks, or other financial assets.
Original documents are vulnerable to theft, fire, water damage, and humidity. Even with gated access and on-site cameras, our facilities aren’t equipped to provide the same level of security as a fireproof home safe or a bank’s safe deposit box.
5. Check Facility Rules Before Storing Restricted Items
Beyond the categories above, our facilities maintain a broader storage restrictions list that covers illegal items, weapons, and more. Here’s a quick overview of prohibited storage items:
- Illegal or Restricted Goods – Storing counterfeit merchandise, stolen property, or illicit substances is a criminal offense. Our facilities cooperate with law enforcement, and units can be opened under court order. Even storing items on someone else’s behalf makes you legally responsible for their contents.
- Firearms and Ammunition – Even licensed gun owners should avoid storing weapons in standard storage units. Temperature fluctuations degrade ammunition and cause corrosion, and most facility agreements explicitly prohibit banned storage items such as firearms, regardless of ownership status. A UL-rated home gun safe or a licensed firearm storage facility is a safer, compliant alternative.
- Moisture-Prone Items – Wet clothing, damp furniture, and unwashed appliances introduce moisture that breeds mold. Always allow items to dry completely before placing them in storage. For long-term storage of wood furniture, electronics, or textiles, add moisture absorbers inside each container.
