Self storage facilities in Kemah are businesses composed of real estate or personal property cargo transit containers divided into self storage spaces that are rented to rental space tenants on a monthly basis. These storage units or rooms are typically windowless, walled with corrugated metal, and lockable by the renter. Used to store merchandise, these units are different sized. Larger units have roll-up type garage doors. A controlled access facility may employ security guards, surveillance cameras, door alarms and some means of electronic gate access, to ensure that access is granted only to those that rent.
