City Storage Unit Size Guide
Whether you’re looking to store important documents or the contents of a full three-to-four bedroom home, City Storage has the unit size for you. You can choose to rent a self-storage unit at one of our three convenient locations or perhaps a mobile storage unit will better suit your needs.
We believe that one size does not fit all – especially when it comes to storage units. Simply provide us with a detailed description of the contents you need to store in our contact form, and a storage specialist can help you to determine which size suits your unique needs.
