Iredell County, NC Accessory Structures: Shed & Carport Rules (2026)

Performance Requirement R1, Accessory Buildings and Structures, governs sheds, detached garages and similar structures countywide. In residential districts, an accessory building may not be erected in front of the principal structure's front building line, within 25 feet of a side street on a corner lot, or within 10 feet of any property line that is not a street line or of any other building on the same lot. A structure larger than 2,000 square feet must be set back at least 30 feet from any property line, though that 30-foot rule drops away if the adjoining property is zoned commercially or is a legal nonconforming commercial use.

Height cannot exceed the district's limit for the principal structure, and the building must be accessory to an existing or under-construction principal building on the same lot; it cannot be used for human habitation except as an accessory dwelling unit permitted under R6. On lots of one acre or more, R1(B) allows an accessory building in the front yard if it sits at least 150 feet back from the frontage right-of-way, and a single gazebo-type structure may sit in the front yard at half the principal building's required setback.

Metal carports up to 400 square feet may stand in the front yard if they meet the principal structure's front setback. Square footage is measured from the outermost structural support members of any roofed portion, including covered porches and open storage areas, so an attached porch or overhang counts toward the 2,000-square-foot threshold that triggers the 30-foot setback.
