What term is commonly used for small, secure storage units rented to individuals and small businesses?

The term "self-storage" specifically refers to small, secure storage units that can be rented by individuals and small businesses for the purpose of storing their personal belongings, inventory, or other items. These facilities typically offer a variety of unit sizes and can often be accessed by the renter at their convenience, providing flexibility and security for stored items.

Unlike commercial storage, which might imply more extensive or specialized storage options for businesses, self-storage focuses on personal and smaller-scale business needs. Industrial storage typically refers to larger facilities designed for storing goods in the supply chain or manufacturing process rather than personal belongings. Warehouse storage is generally associated with larger storage spaces for inventory or goods meant for wholesale distribution rather than individual items, underscoring the difference in scale and purpose.

Thus, "self-storage" is the most accurate and commonly used term for the type of facility described in the question, highlighting its focus on individual or small business rentals for secure storage solutions.
