Rock Hill, SC Home Business: Signage Rules (2026)

Sign regulation in Rock Hill sits at the intersection of zoning authority granted by S.C. Code §6-29-720 and First Amendment doctrine. The U.S. Supreme Court in Reed v. Town of Gilbert (2015) held that content-based sign regulations are subject to strict scrutiny; municipalities can regulate physical characteristics but cannot differentiate based on message (real estate signs treated differently from political signs treated differently from home-business signs is unconstitutional). Chapter 31's sign regulations must comply with Reed's content-neutrality requirement. For home occupations, typical rules include: maximum sign area of approximately 1 to 2 square feet, wall-mounted only (no freestanding or pole signs in residential districts), non-illuminated, no animated or flashing elements, and no off-premises display. Off-premises advertising in residential districts is generally prohibited entirely. Major home occupations approved by special exception may receive specific signage allowances in the Board of Zoning Appeals approval. Rock Hill Code Enforcement responds to complaints. Sign variance requests go to the Board of Zoning Appeals under S.C. Code §6-29-790 / §6-29-800. Historic district properties (Rock Hill has multiple designated historic districts including portions of downtown and Old Town) face additional review where the Historic Preservation Commission has jurisdiction; signs in those districts may require a Certificate of Appropriateness in addition to a sign permit.
