3 rules for unincorporated Dorchester County, South Carolina.
Verified from official government sources
No South Carolina statute limits yard political signs. Dorchester County reaches them only through its Zoning and Land Development Standards, and Summerville through its own zoning. Those rules must stay content-neutral after Reed v. Town of Gilbert, so a town cannot single out political signs by message.
No South Carolina statute governs garage-sale signs; Dorchester County handles them as temporary signs under its Zoning and Land Development Standards. A sign on your own lawn is generally fine and time-limited, but one staked in the road right-of-way or on a utility pole is removed.
No South Carolina or Dorchester County law limits holiday lights, inflatables, or yard displays. The county's zoning reaches decorations only on neutral grounds like sight-line obstruction, and no permit is required. The real limits come from HOAs and deed restrictions, common in the Summerville-area subdivisions.
