Tips for Organizing Storage Units (and Why You Might Not Need One at All)

Renting a storage unit can feel like a fresh start—finally, some extra space to stash all those items you’re not quite ready to part with! But organizing storage units can quickly get out of control and become a forgotten land of cardboard boxes, broken furniture, and “I’ll go through it someday” promises. 

Whether you’re renting short-term during a move or using it for long-term storage, organizing your unit makes all the difference in accessibility, cost, and peace of mind.

Before we dive into tips for organizing your storage space, let’s talk about the first (and perhaps most important) step: decluttering.

Do You Really Need a Storage Unit?

Currently, 33% of Americans have a storage unit and another 20% think they’ll need one soon. Sometimes, the best storage solution is to simply have less stuff. Many people rent a storage unit as a quick fix to avoid making tough decisions about what to keep, donate, or toss.

Storing things you no longer use or need can become an expensive habit with the average cost of a 10×10 unit (enough to store a 1 bedroom apartment) at around $120 per month. Need climate control? Expect a bump in cost for that feature.  It’s no wonder that the storage unit industry brings in around $30 billion in revenue per year! 

Before renting (or when preparing to organize an existing unit), go through your items with a critical eye. Ask yourself:

  • Have I used this in the last few years?

  • Is it worth the monthly fee to store this?

  • Could someone else benefit from it more right now?

By taking the time to declutter first, you might realize you could downsize the unit or eliminate the need entirely.

But if you’ve assessed your belongings and a storage unit still makes sense, let’s make the most of that space!

1. Label Everything (Seriously, Everything)

When you’re stacking bins and boxes floor to ceiling, you will not remember what’s inside that unmarked cardboard box three months or even three years from now. Use large, easy-to-read labels on at least two sides of every container. 

Bonus points for color-coded labels by category (e.g., red for holiday decor, blue for kitchen gear, green for baby items). One client even labeled her boxes by number, then recorded every item inside on a spreadsheet for easy reference later. Now that is meticulous!

2. Use Clear Bins for Visibility

Cardboard boxes are fine in a pinch, but clear plastic bins are your new best friend. They’re sturdy, easy to stack, and let you see exactly what’s inside. No more guesswork or unnecessary digging.

3. Create a Storage Map

Think of your unit like a tiny warehouse. Sketch a quick layout or take progressive photos as you’re loading everything in. Keep it on your phone for reference, so you know which boxes are stashed in the back or on the bottom. It can be a lifesaver later when you need to ferret out that winter gear you never thought you’d use again.

4. Prioritize Access to Frequently Used Items

Plan ahead when loading your unit. If you know you’ll need access to certain things—holiday decorations, seasonal clothing, or business inventory—place those items near the front for easy access. Save the back of the unit for long-term items you rarely need.

5. Shelve It Up

If you’re renting a long-term unit and want maximum organization, consider adding freestanding shelving. It keeps items off the floor, improves visibility, and makes it easier to move things in and out. Avoid those avalanches of stuff that come toppling down when searching for your forgotten pickleball racket!

6. Leave Aisles and Stack Smart

It’s tempting to cram every last square inch of space, but leave a narrow aisle (if possible) so you can walk in and reach the back without climbing over your belongings. Stack heavier bins on the bottom and lighter ones on top, just like you would in your garage or attic.

7. Reassess Regularly

Your storage needs change over time. Set a calendar reminder to visit your unit at least once a year to review what’s inside. You might find things you’re finally ready to part with—or rediscover something you forgot you had! Reassessing also serves as a reminder that you’re paying for this space–don’t let it become an expensive junk drawer!

A Thoughtful Approach to Organizing Storage Units

Storage units can be incredibly helpful—when they’re used with intention. But they shouldn’t become a place where clutter goes to hide forever. With a little decluttering, a plan, and some organizing know-how, storage unit organization can be a streamlined, stress-free space that truly works for you.

And remember: the goal isn’t just to store—it’s to store smart.
