S.C. Code § 5-37-120
As soon as practicable after the completion of the assessment roll and prior to the publication of the notice provided in Section 5-37-110, 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 city or county treasurer, a notice stating the nature of the improvement, the total proposed cost thereof, 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 shall contain a brief description of the particular property involved, together with a statement that the amount assessed shall constitute a lien against the property superior to all other liens except property taxes. The notice shall also state the time and place fixed for the hearing of objections in respect to the assessment. Any property owner who fails to file with the municipal council a written objection to the assessment against his property within the time provided for hearing such objections shall be deemed to have consented to such assessment, and the published and written notices prescribed in this chapter shall so state. If all of the owners of property upon which an assessment is to be levied consent in writing to the imposition of such assessment, the provisions of this section shall be deemed satisfied.
