The Best Self Storage Unit Types for Various Needs

May 1, 2023 |

Finding the perfect storage unit isn’t always as simple as it seems. There’s a lot to consider when it comes to choosing the best self storage unit type for your needs. 

In this guide, I’ll walk you through the ins and outs of different storage unit types, along with their advantages and disadvantages. Let’s dive in!

Things to Consider When Hiring a Storage Unit

Before we get into the nitty-gritty of storage unit types, let’s discuss some essential factors to consider when looking for the perfect unit. These factors will help you narrow down your options and make the right decision for your storage needs.


The location of a storage facility is crucial. You want to find a facility that’s convenient for you, whether it’s close to your home or workplace. Remember, the more accessible it is, the easier it’ll be for you to drop off or pick up items.


How much access do you have to the unit? Some facilities offer 24-hour access, while others have limited hours. Make sure to choose a facility with an access schedule that suits your needs.

Indoor vs. Outdoor Units

Indoor units are located within a building, while outdoor units are accessible from the outside. Outdoor units may be more convenient for loading and unloading, but indoor units can provide better protection against the elements.

Temperature Control

Temperature-controlled storage units maintain a stable temperature and humidity level. These units are perfect for sensitive items, like electronics, artwork, or wine. If you need to store items that could be damaged by extreme temperatures or humidity, a temperature-controlled unit is a must.


Is the storage facility staffed or monitored by CCTV? Security is an essential factor to consider, especially if you’re storing valuable items. Look for facilities with 24-hour video surveillance, on-site staff, and gated access for added peace of mind.


Storage facilities may offer insurance coverage for your belongings, but it’s important to review their policy and consider purchasing additional coverage if needed. Some homeowner’s insurance policies may also cover your items in storage, so be sure to check with your provider.

Internal Secured Lockable Rooms

One popular storage unit type is the internal secured lockable room. These units are located inside a building and offer several advantages.


Being located inside a building, these units provide an added layer of security. They often require a unique access code or key, ensuring that only authorized individuals can enter.

With an indoor location, these units shield your belongings from weather-related damage, such as water damage, rust, or fading due to sunlight exposure.

Many indoor facilities offer temperature-controlled units, which can be essential if you’re storing sensitive items.


Indoor units can sometimes be less convenient for loading and unloading items, especially if they’re located on an upper floor or require navigating narrow hallways.

Due to the added security and protection from the elements, indoor units can be more expensive than their outdoor counterparts.

External Storage Containers

Another common storage unit type is the external storage container. These units are usually situated outside and provide a convenient, drive-up storage solution.


With drive-up access, you can load and unload your belongings directly from your vehicle. This feature makes external storage containers ideal for those who need frequent access to their items.

External storage containers come in various sizes, making it easy to find the right size for your needs. Plus, with their ground-level location, you don’t have to worry about navigating stairs or elevators.

Outdoor storage units tend to be more affordable than indoor units, making them an attractive option for those on a budget.


While most outdoor storage containers are designed to withstand the elements, they may not provide the same level of protection as indoor units. If you’re storing items that could be damaged by water, humidity, or temperature fluctuations, you might want to consider an indoor unit instead.

Although outdoor storage facilities often have security measures like gated access and surveillance cameras, they might not be as secure as indoor units due to their more accessible location.

Deep Storage

Deep storage is a lesser-known storage option that’s perfect for those who need to store items for an extended period and don’t require frequent access. These units are often located in remote, underground facilities, providing long-term, secure storage.


Deep storage facilities typically have robust security measures in place, such as restricted access, 24-hour surveillance, and advanced alarm systems. This level of security can be especially appealing if you’re storing valuable or irreplaceable items.

Deep storage units are often located underground, providing a naturally stable environment that’s protected from temperature and humidity fluctuations. This protection makes deep storage ideal for items that need a consistent climate, like important documents or artwork.

Because deep storage units are designed for long-term use, they often offer lower rates for customers who commit to an extended rental period.


Due to their remote location, deep storage units are less convenient for those who need regular access to their belongings. They’re best suited for individuals who can plan visits in advance and don’t need to retrieve items frequently.

While deep storage can be more cost-effective over time, the initial investment can be higher than other storage options due to factors like transportation and setup costs.
