While most major cities today have at least one self-storage facility available, it's a relatively new industry. As humans have continued to consume more, they have also needed more space to store their belongings.
Self-storage operations trace their roots back to England when British citizens would safeguard their valuables in the banks before long voyages. Overcrowded vaults led to the need for larger storage facilities - usually warehouses. As warehouses prices rose, storage facility owners were forced to look into more economical solutions.

The first self-storage facility, as we know them today, was established in Texas in the mid-1960’s and rented space at .15 cents per square foot/month. It was so successful that the concept quickly spread across the U.S. and Canada — and the rest is history.
