ADU rules in Cornelius, NC — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Cornelius permits accessory dwelling units in select residential zoning districts, subject to size, owner-occupancy, and design standards in the Land Development Code.
The Cornelius Land Development Code allows ADUs (sometimes called accessory apartments or guest houses) in certain single-family zoning districts, typically capped at 800 square feet or 50 percent of the main dwelling's heated floor area, whichever is less. The primary dwelling must generally be owner-occupied. ADUs require a zoning permit and full building permit, and must meet the same setback and height standards as the principal home. Short-term rental of an ADU may be further restricted.
Unpermitted ADU use can trigger a stop-work order, 500 dollar civil penalty, and required correction or removal of unpermitted habitable space.
