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

Sec. 21-285 sets the accessory structure standards for the RA, RR, RS, MHP and MFR zoning districts, covering sheds and similar buildings including recreational homeowner outbuildings the code labels RHOs. The footprint limit is absolute: accessory structure footprints, including those used as RHOs, shall not exceed ten percent of the size of the lot on which the structure is located. Side and rear setbacks are tied to the structure's size on a three-tier table: a building of 0 to 4,000 square feet needs a 10-foot side and rear setback, 4,001 to 8,000 square feet needs 40 feet, and 8,001 square feet and over needs 80 feet.

Regardless of size, accessory structures are not allowed in the required front setback, so a shed cannot be placed in front of the principal dwelling's setback line even if the side and rear numbers would otherwise be met. The size-based setback table and footprint cap do not apply to fences, mailboxes, landscaping features, gazebos and similar minor structures, which the section exempts outright. Placement of any accessory structure still triggers the general permitting process in Sec. 21-272: a zoning permit is required before placement, and construction or structural alteration without a building permit from the building inspections department is unlawful in its own right.
