What is Portable Storage?

Portable storage is the ultimate storage hack for those who need to maximize flexibility without sacrificing security and weatherproofing. You might have seen a storage container with wheels in a neighbor’s yard before a big move, or maybe a steel mini mobile storage container or two on a construction site. Those are portable storage solutions: secure portable storage units that come in a variety of sizes to meet the needs of your move, renovations, and accessibility requirements.

Larger than a portable storage closet, ranging from 7-16 feet long, portable storage units can be parked outside your door, so you can load them up and unpack them at your convenience. The best part? When you’re ready to move your portable storage container, you can have it picked up and transported to its next destination whenever you want.

What Size Storage Container Do I Need?

The size of portable moving containers differs from your traditional stationary storage unit. Movable storage units need to be large enough to comfortably store a room’s worth of stuff, to more than 3 rooms’ worth of stuff - but small enough to be loaded onto a truck and moved. This means that you’re likely to find your mobile storage container in three standard sizes.

Portable Storage FAQs

Portable Storage FAQs

Is it cheaper to rent PODS storage units or standard storage units?

It depends on your specific needs. For short-term storage (1–3 months), portable storage costs more upfront but saves money on truck rentals, gas, and time. When you factor in the convenience of having the container at your location, no transportation costs, and unlimited access, portable storage often provides better overall value.

For long-term storage (6+ months), traditional storage units are usually more economical.

How much does portable or mobile storage cost?

Portable storage costs vary by container size, location, and rental duration.

  • Local moves: $225–$850
  • Long-distance moves: $450–$7,600 (depending on distance)

Monthly rates:

  • Small (8-foot): around $150/month
  • Medium (12-foot): $175–$225/month
  • Large (16-foot): $200–$300/month

Many companies offer package deals that include the first month and delivery, making it easier to budget for your storage needs.

Will my portable storage container come with a lock?

Most portable storage companies do not provide locks — you'll need to supply your own high-quality padlock or disc lock for security. This gives you complete control over access to your belongings.

Companies like PODS and 1-800-PACK-RAT specifically require customers to provide their own locks. We recommend using a heavy-duty, weather-resistant padlock or disc lock designed for outdoor use.

Some companies sell lock accessories, but bringing your own ensures you have the only keys. Always use a quality lock since your container will be outdoors and exposed to both weather and potential theft.

Can I store my car in a portable storage unit?

Most portable storage containers are not suitable for vehicle storage due to size and weight limitations.

  • Standard 8-foot and 12-foot containers are too small for most cars.
  • Even 16-foot containers often lack sufficient width.
  • Containers typically have weight limits (4,000–6,000 lbs), which a car plus belongings could exceed.

They also sit low to the ground without proper ramps for driving vehicles inside.

For vehicle storage, consider traditional storage facilities with drive-up units or covered parking options specifically designed for cars, RVs, and boats.

Can I live in my mobile storage unit?

No, you cannot live in a portable storage container. These units are designed only for storing belongings and are not suitable for human habitation.

They lack proper ventilation, insulation, plumbing, electrical systems, and safety features required for living spaces. Most rental agreements explicitly prohibit using containers as living quarters, and doing so would violate local zoning laws and building codes. Additionally, portable storage containers are not weatherproofed for human comfort and can become extremely hot or cold.
