1. Assuming All 10x20 Units Are the Same
Just because a storage unit is labeled "10x20" doesnt mean every facility offers the same features. Some may have low ceiling heights, limited door clearance, or indoor-only access, which could impact what you can storeespecially if you're considering vehicle storage.
? Can a car fit in a 10x20 storage unit?
Yesmost standard cars, SUVs, and even small trucks will fit inside a 10x20 unit. However, the door size and height clearance matter just as much as the floor space. If you're storing a vehicle, make sure to:
-
Confirm door dimensions
-
Ask if vehicle storage is allowed
-
Check if the unit has drive-up access
Always tour the unit in person or request exact specifications before committing.
2. Not Measuring Your Belongings (or Vehicle)
A 10x20 unit offers 200 square feet of space, which sounds like a lotand it isbut if youre planning to store large furniture, boxes, AND a vehicle, you need to measure everything.
For example:
-
A Toyota Camry is around 16 feet long
-
A Ford F-150 can stretch over 20 feet
-
Once a car is inside, youll have limited space left for anything else
This makes planning essential. Measure your car and other items ahead of time to avoid overstuffing or realizing too late that you need a larger unit.
3. Skipping Climate Control for Sensitive Items
If youre storing wooden furniture, electronics, artwork, or anything that can be damaged by moisture or temperature fluctuations, climate control is a mustespecially in areas with hot summers or cold winters.
Many people opt for a 10x20 unit thinking theyre saving money by choosing a basic unit, but failing to protect valuable belongings can lead to costly damage. Mold, rust, warping, and cracking are all preventable with the right environment.
If your vehicle is classic or high-end, you may also want climate-controlled vehicle storage to protect against humidity.
4. Neglecting Security Features
A 10x20 storage unit is large enough to store thousands of dollars worth of itemsor an entire vehicleso security should be a top concern. Dont make the mistake of choosing the cheapest facility without checking what security measures are in place.
Look for:
-
24/7 video surveillance
-
Gated access with keypads
-
On-site management
-
Strong door latches and locks
Bonus tip: Invest in a high-quality disc lock for added protection, especially if you're storing a car or valuable equipment.
5. Poor Organization and Packing
One of the most avoidable yet common mistakes renters make is randomly filling the unit without a plan. Whether youre storing household goods or combining furniture and a vehicle, organizing the space efficiently will save you major headaches.
Tips for better organization:
-
Use uniform boxes and label everything
-
Leave a walkway down the middle if possible
-
Place frequently used items in front
-
If storing a car, park it in reverse so the drivers side door is accessible
-
Use the vertical spaceshelves and stackable bins can help
Without organization, retrieving even a single item becomes a major chore.
Bonus: Not Asking the Right Questions
Always ask the facility:
-
Can a car fit in a 10x20 storage unit at this location?
-
Is vehicle storage permitted and insured?
-
Are there restrictions on fluid levels, fuel, or battery disconnection?
-
Do I need to provide vehicle registration and insurance?
Not all 10x20 units are vehicle-ready, so confirming these details is crucial before signing the rental agreement.
