Can I legally add an accessory dwelling unit to an Awendaw house?

Adding an accessory dwelling unit to an Awendaw house depends on the town's own zoning district and setback rules, plus whether the property's septic system has capacity for a second unit, since much of Awendaw isn't on public sewer. Rural acreage in Awendaw sometimes has more flexibility than a tighter in-town lot, but that still needs confirming parcel by parcel.
