Greenwood County, SC Sign Regulations: Digital Billboards (2026)

Section 6-3-115(k) regulates automatic changeable copy boards, the county's term for digital or electronic billboard displays. Every such board is capped at 50 square feet of surface area and must be kept programmed and lit so its text stays legible at all times; a temporary sign permit can never be issued for a site with an automatic changeable copy board, and the board itself cannot double as a portable or temporary sign unless a temporary permit has separately been obtained. In the C-2 general commercial district, boards may not flash or scroll, though animated graphics are allowed as a background behind the text, copy may change no more often than every 15 seconds, and transitions between messages must take less than one second.

In every other zoning district, an automatic changeable copy board is allowed only on a lot of at least three acres occupied by a religious, public, educational, or public recreational use, cannot carry off-site advertising, cannot flash, scroll, or use any animation at all, and can change copy no more than once every 60 seconds. Section 6-3-115 also carries a broader prohibition on flashing signs, sign flashers, or animators of any kind, and the zoning administrator holds standing authority to revoke a sign permit at any time on finding that a sign no longer meets the section's requirements.
