Raleigh, NC Accessory Structures: Carport Rules (2026)

Raleigh UDO Section 1.5.7 regulates carports as accessory structures when freestanding and as extensions of the principal dwelling when attached. Unlike sheds, carports do not enjoy a permit exemption under the NC Residential Code because of their span, roof loading, and potential to become enclosed spaces; a building permit is required for any carport regardless of square footage. For freestanding carports, the accessory structure setback applies: 5 feet from side and rear property lines, and placement only in the rear or interior side yard. Attached carports are treated as part of the main dwelling and must meet principal-structure setbacks, which in most R-4 and R-6 zones are 10 feet from the side lot line and 20 feet from the front property line. Height is capped at 20 feet for detached carports. Fabric and metal portable carports (the common white or tan tent-style units sold at Costco and Lowe's) are regulated identically to permanent structures once they remain in place more than 180 days, and many Raleigh HOAs prohibit them outright through covenants. Carports must have engineered anchoring for 115 mph wind speed in Wake County; manufacturer anchor kits typically satisfy this when installed per instructions. Converting a carport to an enclosed garage requires a new building permit, firewall separation per R302.6, and zoning review. In historic overlay districts like Oakwood and Boylan Heights, the Raleigh Historic Development Commission must approve any new carport for compatibility with the district's architectural character before a permit issues.
