What Not to Do When Using a Self-Storage Unit: 9 Common Mistakes to Avoid

Self-storage units are a convenient and affordable way to store everything from furniture and keepsakes to business inventory and seasonal gear. Whether you’re moving, downsizing, or just trying to declutter your space, renting a storage unit can offer the breathing room you need. But not all storage experiences go smoothly, especially if you fall into some of the common traps that new renters often overlook.

To help you avoid costly or frustrating missteps, we’re breaking down the most common self-storage mistakes and what you can do instead.

What Not to Do When Using a Self-Storage Unit

1. Failing to Choose the Right Unit Size

One of the most frequent mistakes people make is choosing a unit that’s either too small or unnecessarily large. If your unit is too small, you’ll end up cramming things in and risking damage. If it’s too large, you’re simply paying for space you don’t need.

The fix: Take inventory of what you’ll be storing and use your facility’s sizing guide (or ask for a tour) to choose the right fit. When in doubt, it’s better to leave room for walkways so you can access items without unpacking everything.

2. Not Labeling or Organizing Boxes

It might seem efficient to toss everything into boxes and worry about organization later, but that decision will come back to haunt you. Unlabeled or poorly packed boxes can turn your unit into a maze of mystery, especially during a return visit.

The fix: Label every box clearly on multiple sides, and keep a simple inventory list of what’s inside each one. Organize your storage unit by grouping similar items and placing frequently used items near the front.

3. Storing Prohibited or Hazardous Items

Certain items should never be stored in a self-storage unit—either because they’re dangerous or because they violate facility policies. This includes flammable materials, gasoline, paint, perishable food, live animals, and firearms.

The fix: Always check with your storage facility for a list of prohibited items. If you’re unsure about something, ask before you store it. Safety should always come first.

4. Using the Wrong Packing Materials

Not all boxes are created equal, and using flimsy or damaged materials can lead to broken items, especially during stacking or long-term storage. Plastic bags, for instance, trap moisture and can lead to mildew or mold.

The fix: Invest in high-quality boxes, plastic storage bins, bubble wrap, and packing paper. Wrap fragile items individually and use furniture blankets or pads for bulkier items.

5. Neglecting to Clean and Prep Items Before Storage

Storing items that are dirty, damp, or unprepared can lead to odor buildup, staining, or even mold and mildew growth over time.

The fix: Clean and dry items thoroughly before storing. Vacuum upholstered furniture, wipe down appliances, and launder clothing. For appliances, leave doors slightly ajar to allow airflow and prevent musty smells.

6. Skipping Climate Control When It’s Needed

Not all items handle temperature and humidity changes well. Electronics, wood furniture, artwork, and documents can warp, crack, or deteriorate if exposed to extreme fluctuations.

The fix: If you’re storing sensitive or valuable items, opt for a climate-controlled unit. While it may cost a bit more, it offers peace of mind and long-term protection.

7. Packing Your Unit Without a Plan

Haphazardly stacking boxes and furniture might feel like you’re saving time, but it makes accessing specific items nearly impossible later. Worse, unstable stacking can lead to crushed boxes or falling hazards.

The fix: Create aisles or leave a small walkway through the center of your unit so you can access items as needed. Stack heavier boxes on the bottom and lighter ones on top. Store furniture vertically when possible to save space.

8. Forgetting to Insure Stored Belongings

Even in the most secure and modern storage facilities, things can happen—floods, fires, break-ins. If your items aren’t insured, replacing them could be expensive and stressful.

The fix: Ask your storage facility about insurance options. Some may offer policies through the facility, or you may be able to add a rider to your renter’s or homeowner’s insurance. Either way, having coverage is worth the peace of mind.

9. Neglecting Regular Check-ins

Once your items are out of sight, it’s easy to forget about them. But not checking in regularly can lead to missed signs of damage, leaks, or pests.

The fix: Visit your unit every few months. Check for dust buildup, moisture, or signs of rodents. If you catch problems early, you’ll avoid bigger headaches down the line.

A self-storage unit should make your life easier, not more complicated. By avoiding these common mistakes, you can make the most of your storage space while protecting the items that matter to you. Whether you’re storing family heirlooms, furniture, business inventory, or seasonal items, the key is preparation, organization, and a little extra care.
