Summary
In unincorporated Orangeburg County, off-premises billboards are allowed only with a zoning permit in the CG (General Commercial) and BI (Business/Industrial) districts. Most billboards are capped at 600 square feet and 36 feet in height, but the Zoning Ordinance gives a bonus to signs within 600 feet of an Interstate right-of-way, up to 1,200 square feet with no height ceiling at all.
(C) - 500 ft. minimum distance required by this section shall be measured between billboards located on either side of the street along the centerline of the street from which the billboard is viewed, when meeting this requirement, a billboard may be located on the same lot or parcel with one "other" sign. ... (E) - 600 square feet, except where located within 600 feet of an Interstate ROW, where the maximum shall be 1,200 square feet. ... (G) - There is no height limitation on signs where located within 600 feet of an Interstate ROW (measured from the average roadway grade level); maximum height of signs not within this prescribed area shall not exceed 36 feet.
Full Breakdown
2. That table lets a billboard onto private land only with prior permit approval ('P'), and only in the CG and BI columns; every other zoning district, including all three residential districts, RO, CN, FA, RC and the institutional column, is marked 'N' for not allowed under any circumstances. Table 5's dimensional standards for billboards then split further based on distance from an interstate: the baseline maximum sign area is 600 square feet with a 36-foot height cap, but Note (E) doubles the allowed area to 1,200 square feet for a billboard located within 600 feet of an Interstate right-of-way, and Note (G) removes the height cap entirely inside that same 600-foot band, measured from the average roadway grade.
Because Orangeburg County sits on both I-26 and I-95, that bonus applies to billboards facing either freeway. Spacing is still controlled: Note (C) requires a minimum 500-foot separation between billboards, measured along the centerline of the street from which the sign is viewed, though a billboard may share a lot with one 'other' (on-premises) sign once that spacing test is met. Every billboard also needs the setback shown in Table 6: five feet from the property line in most districts, two feet in CG. 13 must include a site plan, the sign's dimensions and, for any sign over 36 square feet, a South Carolina-licensed engineer's certification that it is structurally sound.
Violations & Fines
Erecting or enlarging a billboard without the required CG/BI permit, or building one oversized or too tall for its distance from the interstate, is a misdemeanor under Section 9.18 of the Zoning Ordinance, punishable by a court-set fine, with each day the violation continues counted as a separate offense. The Zoning Administrator can also pursue an injunction, mandamus action or other court order to force removal or correction, and may deny a Certificate of Occupancy until the sign is brought into compliance.
