N.C. Gen. Stat. § 44A-44.1: Possession vested in occupant.

Unless the rental agreement specifically provides otherwise, the exclusive care, custody, and control of all personal property stored in a storage space at a self-service storage facility shall remain vested in the occupant until the property is sold as provided in this Article or otherwise disposed of. The owner of a self-service storage facility is a commercial landlord who rents space. Unless the rental agreement specifically provides otherwise, while the personal property remains on the owner's premises, the owner is liable for damage caused by the intentional acts or negligence of the owner or the owner's employees.
