Self storage is short for self-service storage, and is also commonly referred to as mini storage. Individuals typically rent self storage to store personal items, while businesses often use self storage to store excessive inventory or archived records. The rented spaces are often referred to as units, lockers, and rooms. The facility manager does not take ownership of the items stored, and often cannot access the storage units. For items sensitive to extreme heat or cold, there are often climate-controlled units. See below to locate self storage in South Portland, ME.
