S.C. Code Ann. § 4-35-110

As soon as practicable after the completion of the assessment roll provided in Section 4-35-100, the governing body shall mail by registered or certified mail, return receipt requested, to the owner or owners of each lot or parcel of land against which an assessment is to be levied, at the address appearing on the records of the county treasurer, a notice stating the nature of the improvement, the total proposed cost of it, the amount to be assessed against the particular property, and the basis upon which the assessment is made, together with the terms and conditions upon which the assessment may be paid. The notice must contain a brief description of the particular property involved, together with a statement that the amount assessed constitutes a lien against the property superior to all other liens except property taxes. The notice also must state the time and place fixed for the hearing of objections in respect to the assessment. A property owner who fails to file with the county council a written objection to the assessment against his property within the time provided for hearing the objections is considered to have consented to the assessment, and the published and written notices prescribed in this chapter shall so state.
