Does this affect single-family and small homeowners in Sullivan's Island?

Whether a given policy or rule affects single-family and small homeowners on Sullivan's Island depends entirely on which specific rule is being asked about, since the island's zoning and short-term rental ordinances are set by the town itself rather than adopted from outside sources. Checking directly with the town's zoning office is the most reliable way to know how a specific rule applies to a specific property.
