Scarcity drives price: 10x30s are rare — many Miami facilities only have a handful. When a building has 2-3 10x30s, they don't discount to fill them. If you need the big unit, book early and don't expect the promotions you'd get on a 10x10.

What Actually Fits in a 10x30
A 10x30 gives you 300 square feet with an 8-foot ceiling — 2,400 cubic feet total. In practical terms:
- 3-4 bedroom house: full contents including all bedrooms, living room, dining room, kitchen appliances, and garage items
- Vehicle + furniture: one car (parked inside) plus a 1-bedroom apartment's worth of boxes and furniture on the remaining space
- Small business inventory: e-commerce stock, equipment, shelving — enough space to walk between aisles
- Large boat on trailer: some drive-up 10x30s accommodate boats under 30 ft — see our boat storage guide
- Contractor setup: tools, materials, equipment, and a workbench — a mini-warehouse for one operation
What doesn't fit: two cars side by side (you need a 10x40 or two 10x20s), a full 5-bedroom house, or a business operation that needs loading docks. For those needs, consider a

10x30 vs Two Smaller Units
Sometimes two smaller units beat one giant one:
| Option | Total Cost | Pros | Cons |
|---|---|---|---|
| One 10x30 (climate) | $290-$520/mo | Everything in one place, single lease | Hard to find, expensive, limited availability |
| Two 10x15s (climate) | $320-$560/mo | Easier to find, more locations | Two units, two access codes, splitting inventory |
| One 10x20 + one 5x10 | $270-$430/mo | Flexible sizing, different neighborhoods possible | Managing two units, separate billing |

The verdict: for a 3-4 bedroom house, a single 10x30 is almost always the right answer — the organization and single-access convenience outweigh the premium. For a business that needs 400+ sq ft, consider two 10x20s in different areas or a small warehouse.
Who Actually Needs a 10x30
- Whole-home moves: a 3-4 bedroom Miami home between closings or during renovation — a 10x30 holds it all in one unit, one lease, one access point. See our moving storage guide.
- Vehicle + household: store a car AND a house's worth of furniture — the vehicle parks in the front half, furniture fills the back. See our indoor car storage guide.
- Small businesses: e-commerce inventory, restaurant equipment, contractor materials — a 10x30 is a micro-warehouse at half the cost of commercial space. See our business storage guide.
- Estate settlements: settling a family estate with a whole house's contents — a 10x30 gives you time to sort, sell, and distribute. See our estate storage guide.

Can I store a car in a 10x30 storage unit?
Yes — a 10x30 accommodates one standard car with room for furniture alongside. For two cars, you'd need a 10x40 (rare in Miami) or two separate units. Most Miami facilities require drive-up access for vehicle storage — confirm before booking.
How many 10x30 units are available in Miami?
Very few — most facilities only have 2-5 10x30 units total. It's the scarcest size in Miami-Dade. If you need one, book 4-6 weeks ahead, especially in premium neighborhoods. Hialeah and Homestead have the best availability due to their industrial-zoned facilities.
Is it cheaper to rent one 10x30 or two smaller units in Miami?
For a full house — one 10x30 is usually cheaper and far more convenient. Two 10x15s cost $320-$560 vs one 10x30 at $290-$520. The savings are modest, but the single access point and no split-inventory headaches make the 10x30 the better answer for a single household.
