Mini storage is also called self storage, which is a small warehouse for storing things. The operator converted the large-scale warehouse into several small warehouses, perhaps put in rows of lockers, and rented them out as rental space. Generally, the rent is calculated monthly.

Mini warehouses provide various types of storage rooms ranging from small clothing placement to large item storage according to the different needs of customers. Generally, larger units have rolling gate garage doors. Mini warehouses must provide equivalent statements, statement communications, and automatic transfer equivalents at regular intervals, and they must sign standard storage agreement with customers to ensure that customers are guaranteed by law. What makes customers feel at ease is that the keys and locks of the warehouse door are all the customer's own. The staff of the mini warehouse are different from the storekeepers who work in the warehouse. They cannot open the customer's storage room at will. Unless the customer fails to pay the rent on time in accordance with the lease agreement, the leaser cannot move the goods stored by the customer without authorization. There are usually no windows in the storage room, and the walls are corrugated metal, and the door is locked by the customer. Mini warehouses ensure the safety of the warehouse by employing security, surveillance cameras, and alarm systems. Some advanced mini warehouses require customers to enter a password on the electronic door, perhaps using a proximity card. Some even use biometric fingerprints. Or manual scanner skills.

Customers are generally able to store any harmless, non-toxic, non-perishable items in the mini warehouse, such as personal daily necessities, furniture, motorcycles, backlog of retail products, etc. Some mini silos used to store special items such as wine, fur, antiques, and prescription drugs also have high requirements for temperature control, so the warehouse must be equipped with a temperature control system, and ordinary warehouses can be adjusted by air conditioning.

If the arrears of rent exceed the period agreed in the agreement, the operator has the right to seize the goods stored by the customer and be able to sell them at auction. Write this part into the statute.

On the basis of mini warehouses, some storage companies have introduced more convenient “portable storage”. The renter supplies the storage box and sends it to the customer. After the customer puts the items in the storage box and locks the box, the renter then sends the box to a unified storage center for storage.
