S.C. Code Ann. § 40-59-300

Notwithstanding any other provision of law, a 501(c)(3) eleemosynary organization may construct a residential home with volunteer labor without the presence of a qualifier if the home without consideration is to be transferred to or made available for the use of an underprivileged or low-income family or individual. "Qualifier" for purposes of this provision means a builder or specialty contractor licensed to perform the particular work being done on the site. The cost of the building permit must be borne by the 501(c)(3) organization.
