S.C. Code Ann. § 41-16-120

The Director, pursuant to regulation, may grant exceptions and variances from the requirements of regulations promulgated for any facility. Exceptions or variances must be reasonably related to the age of the facility and may be conditioned upon a repair or modification of the facility considered necessary by the Director to assure reasonable safety. However, no exception or variance may be granted except to prevent undue hardship. These facilities are subject to orders issued pursuant to Section 41-16-110.
