North Carolina building codes exist to keep you safe. Here's what property owners need to know about code requirements for metal structures.
North Carolina adopted the 2018 International Building Code (IBC) and International Residential Code (IRC) as the basis for state building standards, with NC-specific amendments. These codes establish minimum requirements for structural design, wind resistance, snow loads, foundation specifications, fire safety, and accessibility.
Every metal building installed in NC must comply with these codes, and compliance is verified through the permitting and inspection process. This is why building without a permit is so risky — unverified buildings may not meet safety standards.
NC building codes specify design wind speeds by geographic location. Coastal counties require the highest ratings (130-160+ MPH) while inland areas require 95-115 MPH. Your building's engineering must account for your specific county's requirements, your site's exposure category, building dimensions, and opening locations.
Western NC mountain counties have significant snow load requirements that vary by elevation. Watauga, Avery, Mitchell, and other high-elevation counties require engineering for 20-30+ pounds per square foot of ground snow load. Piedmont and eastern NC have minimal snow load requirements.
NC codes specify minimum foundation requirements including footing depth below the frost line, concrete strength and reinforcement standards, anchor bolt specifications, and drainage and grading requirements. These vary by soil type, building size, and location.
