S.C. Code Ann. § 27-31-130

(A) All the co-owners or the sole owner of the property constituted into a horizontal property regime may waive the regime and regroup or merge the records of the individual apartments with the principal property, if the individual apartments are unencumbered, or if encumbered, if the creditors in whose behalf the encumbrances are recorded agree to accept as security the undivided portions of the property owned by the debtors. (B) Notwithstanding subsection (A), in the case of nonprofit long-term care retirement or life care facilities where there are co-owners, a two-thirds vote of the co-owners suffices to waive the regime and regroup or merge the records of the individual apartments with the principal property if the individual apartments are unencumbered, or if encumbered, if the creditors in whose behalf the encumbrances are recorded agree to accept as security the undivided portions of the property owned by the debtors.
