5 Items You Should Never Store in 2025 (Avoid These Mistakes!)

What you Shouldn’t Store in a Storage Unit in 2025

Storage units are a convenient solution when you are moving, downsizing, or just decluttering – but not everything belongs inside one. Whether you are using a climate-controlled space or an outdoor unit, there are certain items that are unsafe, illegal, or impractical to store. Knowing what not to store can help you avoid costly mistakes, damage, or even legal issues. 

 

This guide will walk you through 5 items you should never store in 2025, especially in standard or non-climate-controlled units. 

1. Perishable Foods 

Why You Should Never Store Food Items 

Perishable or even non-perishable food might seem harmless, but in a storage unit, they can quickly become a problem. Food spoils, attracts pests, and creates foul odors – none of which belong in a shared facility. 

 

Even canned goods and boxed items like cereal or pasta can lead to: 

  • Rodent infestations 
  • Mold growth 
  • Insect problems (especially ants and roaches) 
  • Damage to neighboring units 

 

If your storage unit becomes infested due to stored food, you could be held responsible for pest control costs or damages to nearby tenants’ belongings. 

What to Do Instead: 

  • Only store sealed emergency food kits are designed for long-term preservation in climate-controlled units (if allowed). 
  • For moving or long-term storage, donate or toss open or perishable food before storing your belongings. 

 

2. Hazardous or Flammable Materials 

What Counts as Hazardous?

Many people don’t realize they are storing dangerous materials until it is too late. Storage units are not designed to handle chemical reactions, pressure build-up, or fire hazards. 

Do NOT store: 

  • Gasoline, kerosene, or propane tanks
  • Fireworks or ammunition 
  • Fertilizers or pesticides 
  • Cleaning chemicals with strong fumes 
  • Paint thinners, solvents, or motor oil 

 

Even a small leak or spark can lead to fire or toxic fumes – putting not just your unit but the entire facility at risk. 

What to Do Instead: 

  • Take these items to your local hazardous waste disposal site. 
  • Store yard or automotive equipment without fuel and ensure it is cleaned properly before storage. 

 

3. Living Things (Pets, Plants, or People) 

Yes, This Needs to Be Said 

It may sound extreme, but storage units should never be used to house living beings, including animals, plants, or people. Unfortunately, there have been real cases across the U.S. where individuals tried to live in storage units or leave animals or potted plants behind. 

 

Living things require ventilation, light, temperature control, and water. Storage units aren’t equipped for any of these, and using them this way is not only dangerous – it is illegal. 

Consequences of Storing Living Things: 

  • Criminal charges or citations 
  • Eviction from the facility 
  • Fines and possible bans from other storage providers 

What to Do Instead: 

  • Rehome pets or plants before you move. 
  • Look into boarding, foster programs, or temporary care services. 

 

4. Important Documents and Priceless Valuables 

Think Twice Before Storing Irreplaceable Items 

While storage units are secure, they aren’t foolproof – especially for irreplaceable personal items. Even in the safest facility, risks such as theft, water damage, or accidental loss can occur. 

Avoid Storing: 

  • Birth certificates, passports, or social security cards 
  • Family heirlooms or antique jewelry 
  • Cash, coins, or financial assets
  • Rare collectibles or irreplaceable photos 

 

These items carry emotional and legal significance, and their loss can be devastating. 

Best Practice: 

  • Keep valuable documents in a waterproof, fireproof safe at home or in a secure safety deposit box. 
  • Use digital backups for family photos and records. 

 

5. Unregistered or Uninsured Vehicles 

Storage Rules for Boats, RVs, and Cars  

Many people use storage units for vehicle storage – and this is a great idea when done correctly. However, storing a vehicle that isn’t registered, insured, or road-ready can cause major problems. 

 

Storage facilities typically require: 

  • Proof of registration 
  • Proof of insurance 
  • Drained fuel tanks (if stored indoors) 
  • Up-to-date contact information 

 

Why? Because unregistered or uninsured vehicles can be considered abandoned property. If they are damaged or cause issues (e.g., oil leaks, pest attraction), you may be held financially liable. 

Tip: 

If you’re storing a vehicle, be sure to: 

  • Maintain liability insurance 
  • Keep plates up to date 
  • Remove all perishables from the interior 

Bonus: Items That Can Be Stored with Caution 

Some items aren’t necessarily banned but do require extra care: 

  • Electronics: Only in climate-controlled units to prevent heat and moisture damage. 
  • Clothing and fabrics: Store in plastic totes with moisture absorbers. 
  • Furniture: Cover with breathable sheets, not plastic, to prevent mold growth. 
  • Tools and outdoor equipment: Clean and dry thoroughly before storing to prevent rust. 

Frequently Asked Questions 

1. Can I store wine or alcohol in a storage unit?

Only in a climate-controlled unit, and only if allowed by the facility. Most storage companies restrict alcohol due to temperature sensitivity and liability risks. 

2. Are there rules about storing firearms?

Yes. Many storage facilities prohibit firearms due to legal and safety concerns. Always check with your local storage provider. 

3. What if I’m not sure whether something is allowed?

When in doubt, ask! Reputable storage companies like USA Storage will happily review your list of items and advise on what is safe and acceptable.
