1. Choose the right lock for your storage unit

Not all storage facilities are created with equal security measures, so your first order of business should be researching what kind of locks the facility has on hand. Some facilities will have cylinder locks, which are built into the facility doors and are some of the most secure options available, but other facilities will provide a separate lock for you. However, many of these locks aren’t as secure as options you may be able to find on your own, especially if they’re padlocks, which could theoretically be broken with bolt cutters.

Storage.com recommends providing your own disc lock if your unit’s door doesn’t have a built-in cylinder lock. Disc locks are similar to padlocks and are opened with keys, but are built such that the lock doesn’t give much leverage for a bolt cutter to break through it. These locks are also far more difficult to pick than padlocks, thanks to their disc tumblers, even more so if you’re willing to invest in a high-quality lock. Bringing a lock also removes the risk of an unscrupulous facility manager using a master key to get into units.

2. Select a secure facility location 

As a rule of thumb, indoor self-storage facilities will usually be more secure than outdoor facilities. However, whatever you choose, you can maximize your unit’s security by choosing a unit in a well-lit area (allowing unit security can more easily see any potential intruders) and avoiding units near the perimeter of the facility (as they require less effort to access by potential thieves willing to hop the fence). Units closer to the main entrance and office are also easier for security to monitor.

Choosing an indoor storage facility adds an extra barrier for those looking to break in, as they’re well-lit throughout and have an entire building surrounding their units. However, for maximum peace of mind, choose a unit on an upper floor, as these are far more difficult to access in the event of a security failure.

3. Invest in quality security features

You don’t have to worry about unit security all on your own; many facilities have built-in security features to protect your valuable belongings. Here are a few important ones worth seeking out.

  • Gated or locked entry to the facility. A good self-storage facility’s first line of defense will be a strong gate or locked front door to restrict access to renters and employees. Higher-end facilities will have more advanced locking systems, such as biometric locks that are coded to a renter’s fingerprint.
  • High-quality locks on units. Facilities that make security a primary concern will have strong built-in cylinder locks on their storage unit doors. More advanced facilities may have smart locks that you can access with a code or biometrics.
  • On-site security staff. For maximum security, choose a self-storage facility with a dedicated team of security professionals that makes regular patrols and monitors the security systems 24/7.
  • Cameras and lighting. A well-lit facility will be easier to detect intruders in, and a thorough network of security cameras will cover every possible angle of the facility and avoid any blind spots.

Research the facilities you’re considering using our search tool to see what security is available and whether they provide their services during business hours or 24/7. Be ready to pay a little extra for these features, but you’ll find them worth the price if you’re concerned with security.

4. Use strategic packing and organization

If someone manages to bypass security and get into your unit, there are plenty of measures to take when packing and organizing to keep your valuables safe. Store your valuables toward the back of the unit and store less valuable items in front of them to keep attention off of them. Keeping “decoy” items near the front will further protect your valuables, as time is a concern for most intruders, and they’ll most likely want to grab whatever is easiest before they flee the scene.

You can further protect your belongings by storing them in opaque containers such as moving boxes or plastic tubs; bins made of translucent materials are easier for intruders to see the contents of. Lastly, labeling your boxes will help you organize them and remember what’s stored in each, but avoid leaving boxes labeled with valuables, as an intruder may use those labels to identify which containers to rummage through.

5. Document your belongings

Keeping lists and photos of what you’ve stored in your unit not only helps you organize, it can be useful if your belongings are broken or stolen and you need to file an insurance claim. Take plenty of photos of the items you plan on storing and keep them on hand in case you need them, and make a detailed list of the contents of your unit to check against regularly.

For valuable items, electronics, and appliances, make sure you write down the serial number and a description of each when making your list in case you need to file a warranty claim with the manufacturer. You should also get an accurate value of each item in case you need to file an insurance claim for reimbursement.

6. Consider storage insurance

Speaking of insurance, it may be worth investing in specific storage unit insurance if your homeowner’s or renter’s insurance policy doesn’t cover items stored outside of your home or apartment. Some facilities have insurance options available for renters, but these typically cover a smaller amount and cost more than third-party options, so it’s worth researching what’s available before committing to the policy offered by your facility of choice.

Storage insurance policies cover theft, vandalism, and weather-related damage, but typically don’t cover mold or mildew damage, as these are considered the fault of the customer rather than an external source. Before investing in a policy, it’s worth getting a monthly quote and deciding whether the cost outweighs the peace of mind you’ll have knowing your valuable items are covered.

7. Limit access and information sharing 

Another simple way to ensure your storage unit is kept private and secure is to limit the information you share about it. Don’t publicly share your storage unit number, and make sure keys and access codes are only shared with friends and family you trust to help keep your belongings safe.

While facility staff should be trustworthy, it’s best practice to refrain from discussing what valuables you may be storing with them so unscrupulous employees aren’t tempted to get into your unit. Finally, limit what you share on social media about your unit, as modern criminals and intruders will be looking for that information to identify easy targets for theft.

8. Regularly check in on your unit

Regular visits to your storage unit not only improve your peace of mind, but you can also use your regular check-ins to look for signs of tampering and make sure your valuable possessions are clean and free of damage. When visiting your unit, you can reorganize your belongings to keep potential intruders guessing, and occasionally change out the locks and access codes to improve security over time. You should also maintain a positive relationship with facility staff so they know their efforts to protect your unit are appreciated.

9. Secure your unit’s interior

For maximum peace of mind, consider investing in additional security measures within your unit, such as extra locks for storage cabinets and boxes. Weighing down and anchoring your most valuable items will make them more difficult to take without extra effort, deterring smash-and-grab thieves and making it easier for unit security to catch more dedicated criminals.

You can also bring your alarm system to further deter thieves, alerting security and making a disorienting loud noise to throw them off. Incorporating multiple layers of security within your storage unit will be the best practice for keeping intruders away.

10. Know your facility’s security protocols

When renting a storage unit, take extra time to ask about and review the facility’s security protocols so you and the management are on the same page. Here are a few questions to bring with you when meeting with management.

  • How do you keep logs of access to the facility? A high-quality storage facility will keep detailed and accurate logs of the people who access it and the times they enter and exit.
  • How does security monitor the facility? Identify how often cameras are checked and what procedure regular security patrols follow.
  • How can I report an incident? The best self-storage facilities will have a transparent procedure for you to report a security breach and file an insurance claim, even if their security is top-of-the-line.

Some facilities will ask you to write down an alternate contact in case they can’t get ahold of you in the event of a security incident or other issue. Be sure the contact you choose is trustworthy and won’t take advantage of any access you give them to your unit.

Wrapping up: Find a secure self-storage facility near you

A good self-storage facility will provide plenty of built-in security and be deserving of your trust in their staff and technology. However, for maximum security and peace of mind, it’s worth investing in good locks, insurance policies, and extra layers of locks and security within your storage unit. With our tips in mind, find the right balance of security and accessibility to ensure you can get into and organize your unit easily without worrying about other people gaining unauthorized access.

FAQs

In the case of a break-in, check your unit’s contents to compare them with the photos and documentation you have on hand. Report the break-in to facility management so they can address the breach, and if any items are missing, immediately file an insurance claim to recover any financial losses.
If you’re storing less valuable items in your unit or the facility you choose has a robust monitoring system, visiting your unit every three to six months should be more than adequate for regular checkups. Otherwise, a monthly check will help you breathe a bit easier, seeing your belongings in a secure state.
Yes, they usually are. Climate-controlled self-storage units are typically housed in indoor facilities, which have an extra layer of security by virtue of being indoors. Facilities with these units also tend to come with higher-quality technology–if climate control tech is present, high-tech security features are likely to be present as well.
Without the proper measures to protect them from the environment, fragile valuables should never be stored in a unit, such as important documents. You also should refrain from storing electronics in a unit with poor climate control, and avoid keeping cash in a unit.
Do plenty of research, tour the storage facility, and ask the right questions of the storage facility management to identify what security features are available. The most secure facilities will make a point of advertising those features up front.
