S.C. Code Ann. § 44-53-1390: Investigation of lead poisoning case reports; right of entry.

When the department is notified of a lead poisoning case, the department, upon presentation of the appropriate credentials to the householder, and with the consent of the householder or his agent, may enter a dwelling, dwelling unit, or childcare facility at reasonable times and in a reasonable manner for the purpose of conducting a lead-based hazard investigation and may remove samples of objects necessary for laboratory analysis. If the householder refuses admission to the premises, the department may obtain an administrative warrant from a court of competent jurisdiction to investigate the premises. This section also applies to secondary residences and any other premises routinely occupied by the child.
