What is the difference between semi attached and detached homes in Johns Island?

A semi-attached home on Johns Island shares at least one wall with a neighboring unit, while a detached home stands entirely on its own lot with space on all sides, which affects everything from privacy to exterior maintenance responsibility. Semi-attached properties sometimes carry HOA dues that cover shared structural elements, unlike most detached homes.
