S.C. Code Ann. § 38-75-30: Maximum amounts of fire insurance policies; exceptions for manufacturing property and replacement riders.

Notwithstanding Section 38-75-20, insurers may, at the request of owners of property used principally for manufacturing purposes, including places of residence for occupancy by employees, issue policies wholly exempt from Section 38-75-20. Riders or endorsements may, in consideration of an adequate premium or premium deposit, be attached to policies insuring property, indemnifying the insured for the difference between the actual value stated in the policy and the amount actually expended to repair, rebuild, or replace with new materials of like size, kind, and quality the insured property that has been damaged or destroyed by fire or other perils insured against.
