Frequently Asked Questions

1. Can I store my car or boat in a regular unit?

Possibly, if the door height, width, and unit length accommodate the vehicle. But often you’ll need a drive-through or vehicle-designated unit.

2. What is the most commonly rented storage unit size?

The most commonly rented size is 10×10 due to its versatility — it fits a couple of rooms’ worth of items and offers a great balance between cost and capacity.

3. What if I run out of space later?

Many storage facilities, including ours, allow you to upgrade to a larger unit mid-rental if your storage needs increase.

4. Do climate-controlled units require more space or cost more?

They don’t require extra space but generally cost more per square foot. However, for climate-sensitive items like books, electronics, or fabrics, they’re well worth it.

5. How high can I stack belongings in a unit?

That depends on your unit’s ceiling height (often 8 feet). Always leave an aisle, stack boxes evenly, and avoid unstable or overhanging piles.
