Which Industries Use Portable Storage?

The Top 4 Truths About Portable Storage

Truth #1: Portable Storage Containers Are Clean, Freshly-Painted Organizers

Mobile Mini storage containers are the cleanest in the industry and always freshly-painted. The unit is clean; your valuables stay clean. And from the outside it’s not an eyesore, it’s a symbol of your business’s efficiency. Mobile Mini’s extra storage space keeps your inventory organized and your regular place of business free of clutter. We offer extra shelving options for even more space!

Truth #2: Portable Storage Containers Are Affordable For Smaller Businesses

Your only expense is leasing the unit, and you’re only paying for the space you need. Choose your desired length of container and date of delivery and Mobile Mini works closely with your business to find the perfect fit. Storage containers improve your bottom line by speeding up the process of stocking, accounting for and moving your inventory.

Truth #3: Portable Storage Is Strong Against Theft & Vandalism

Like any building, portable storage containers can be a target of thieves. But Mobile Mini’s containers are built Superman Strong to avenge unwanted invasions. They are made of the strongest steel (unlike the windows in your place of business) and are often locked up an area close to the security cameras and night security guards. Mobile Mini containers feature our famous, near-flawless Tri-Cam Locking System. When combined with available Container Guard locks, these wonder containers are more secure than most office buildings.

Truth #4: A Little Extra Insurance Wouldn’t Hurt

Standard practice for businesses is to protect their property with insurance for their storage units. This is typically an addition to their regular business insurance. As secure as they are, portable storage containers are like any other building and items inside can still be at some risk. Mobile Mini recommends business owners insure their possessions. Consider the possibility that one day you or one of your employees forgets to lock up the storage container and items are subsequently stolen. Sometimes there’s no anticipating human error. But you can prepare for it.

How Long are Most Storage Container Leases?

Length of rental depends on the needs of the business or individual. Mobile Mini frequently rents our industry-leading units from a couple months to several years. Especially if you’re uncertain how long your needs may last, renting rather than buying is your best bet.

Mobile Mini Containers Are The Industry's Most Secure

  • Not all storage containers are created equal. Most important is the quality of the locking system. The stronger the locking system the more it will deter vandals and thieves from trying to damage or break into your container.  

  • Can you believe 62% of stolen equipment is never recovered?! Plus, many storage unit thefts aren’t even reported, possibly because they go unnoticed. You must know Mobile Mini secure storage containers offer many benefits over a storage unit facility that is positioned in an obscure or out-of-the-way location.

  • All storage units have some type of locking system. They range from a simple bolt lock like on your front door, to sophisticated systems of rods that make the unit virtually break-in proof. Most common are:

    • Single-locking rod: very much like the bolt lock on your front door
    • Two locking rods: sometimes called a “bi-cam”; better than a single-locking rod but fairly easy to penetrate
    • Tri-Cam Locking System: the premier system available on the market and used exclusively by Mobile Mini; this a network of 3 rods locking into the top, bottom, and a side of the container; similar in design to a bank vault

Which is better? Renting or buying?

It depends on what you need. If you plan on using your Mobile Mini storage container for more than 3 years you should buy. Up-front investment can range from $1,500 to $5,000. Consider the purchase price plus delivery versus the monthly rental fees plus pick-up and delivery.  

Most customers like the flexibility of returning the storage container at any time and having the options of changing the size and features of their unit; renting for them is the best option. When you purchase a unit: if it is damaged or vandalized you would have to pay for that yourself.

There are less upfront costs if you choose to rent. Rental fees range between $75-$200 depending on the size and condition of the container. And when you’re done with the container, all you need to do is call Mobile Mini’s 24/7 industry-best customer service and schedule a convenient pick-up. Usually pick-ups are in 5 days or less. Charges stop the moment you call in the pickup.  

If you have any problems while renting a Mobile Mini unit, call the world’s best 24/7 customer service and you’ll always be taken care of. If you own your own unit, well…it can be the Wild West out there, and unfortunately you’re on your own when problems arise.

What Happens After Ordering?

Mobile Mini containers are delivered on a tilt-bed truck and trailer by the industry’s safest drivers. Mobile Mini has an industry-leading TRIR score of under 1.0 with a goal of 0. Additional factors to consider when scheduling a delivery:

  • Road conditions
  • Weather conditions
  • Ground conditions
  • Overhanging trees and wires
  • Driveway space upon entry

When your Mobile Mini delivery truck arrives, the driver will back in and then lower the tilt-bed until the storage container unit is touching the ground on one side.  The tilt-bed pulls straight out from under the storage container until it lays flat on the ground.  It will be important to communicate which way you want the doors to face before delivery.

Please remember the container and its contents are the customer’s responsibility once on your property. Mobile Mini also offers a Loss Limitation Waiver (LLW), which may be worth the cost depending on what you’re storing. Ask about a LLW before signing a contract.

Quick Tips For Renting A Portable Storage Container

  1. Your delivery fee will be based on mileage. How far is your property from the storage container site?  

  2. Timing of your delivery. Mobile Mini guarantees fast and reliable pick-up and delivery with advanced notice. Most deliveries happen within 24-72 hours. Even same-day delivery and pick-up is possible per availability. Express Pickup and delivery service options are available at times upon request with an expedited delivery fee.

  3. It’s important to know if a permit is required for temporary storage. Usually it depends on whether there are any regulations and if your property is located in an urban or rural area. It’s always recommended to check with your local authorities ahead of time. Common city permit requirements include a 90-day maximum on your property and placement of the unit 5- to 15-feet away from your property line.

  4. For a 20-foot storage container you’ll usually need 75 feet of straight clearance. 40-foot containers, more like 100 feet. For most containers you’ll need a minimum of 12 feet of width clearance and 20 feet of overhead clearance. The truck and trailer weigh over 30,000 lbs. Remember to communicate if your site is at ground level, on a concrete pad, a paved road and if the site is prone to flooding. You’ll want to make sure you have enough room for semi-truck access. Communication in advance with the driver is recommended. This will allow for the driver to communicate with a site contact about delivery timing, access to facility entrance and if there are any delays or unexpected setbacks.
