Are ADUs legal on Mount Pleasant?

Whether an ADU is legal on a specific Mount Pleasant lot depends on that property's zoning district, setbacks, and whether it has capacity for a second unit's utilities, since the town's zoning varies by neighborhood rather than applying one blanket rule. Some Mount Pleasant subdivisions also carry HOA restrictions that block a second structure even where town zoning would otherwise allow it. Brian Beatty can confirm both the zoning and any HOA rules on a specific Mount Pleasant property before you plan one.
