An elevator safety control device realizing suppression in increase in cost and labor hour of installation and maintenance without deteriorating safety of normal safety control functions even when a plurality of safety control functions are provided. The elevator safety control device includes an independence assurance unit assuring independence of a safety control function. The independence assurance unit assures independence of each of the safety control functions by monitoring whether or not the safety control function accesses a memory other than a permitted region. When the independence assurance unit detects an access to the memory other than the permitted region by a predetermined safety control function, the elevator safety control device stops a car.
