Self storage (a shorthand for "self-service storage," and also known as "device storage") is an industry that rents storage space (such as rooms, lockers, containers, and/or outdoor space), also known as "storage units," to tenants, usually on a short-term basis (often month-to-month). Self-storage tenants include businesses and individuals. When discussing why a storage space is rented, industry experts often refer to "4Ds of life" (death, divorce, downsizing, and dislocation; the latter can refer to either the renter relocating to another area and needing space to store items until they can be moved to the new location, or a subsequent marriage resulting in the couple having duplicate items). Description Self-storage facilities rent space on a short-term basis (often month-to-month, though options for longer-term leases are available) to individuals (usually storing household goods; nearly all jurisdictions prohibit the space from being used as a residence) or to businesses (usually storing excess inventory or archived records). Some facilities offer boxes, locks, and packaging supplies for sale to assist tenants in packing and safekeeping their goods, and may also offer truck rentals (or may allow free use of a truck for a new tenant). Most storage facilities offer insurance for purchase; also, the lessor may be covered by their own insurance policy (if such policy has coverage for items stored off the premises of the insured) or may purchase insurance to cover the items (which the facility may offer as a service through a third-party carrier, and in some cases may require the lessor to purchase as a condition of rental). The rented spaces are secured by the tenant's own lock and key. Unlike in a warehouse, self-storage facility employees do not have casual access to the contents of the space (and, thus, the facility is generally not liable for theft). A self-storage facility does not take possession or control of the contents of the space unless a lien is imposed for non-payment of rent, or if the unit is not locked the facility may lock the unit until the tenant provides their own lock. History Although there is historical evidence of publicly available storage in ancient China, modern self-storage facilities (in which the tenant has exclusive access to the storage space) did not begin to appear until the late 1960s. The first self-storage facility chains opened in Texas. This was often helped by the fact that most homes in Texas do not have
