This code applies to residential buildings and the building sites and associated systems and equipment.
The Statutory authority for Rule-making is G. S. 143-136; 143-138.
Exception:

The Statutory authority for Rule-making is G. S. 143-136; 143-138.
This code shall regulate the design and construction of buildings for the effective use and conservation of energy over the useful life of each building. This code is intended to provide flexibility to permit the use of innovative approaches and techniques to achieve this objective. This code is not intended to abridge safety, health or environmental requirements contained in other applicable codes or ordinances.
Where, in any specific case, different sections of this code specify different materials, methods of construction or other requirements, the most restrictive shall govern. Where there is a conflict between a general requirement and a specific requirement, the specific requirement shall govern.
Where a building includes both residential and commercial occupancies, each occupancy shall be separately considered and meet the applicable provisions of the IECC—Commercial Provisions or IECC—Residential Provisions.
Residential buildings shall meet the provisions of IECC—Residential Provisions. Commercial buildings shall meet the provisions of IECC—Commercial Provisions.
The code official shall be permitted to approve specific computer software, worksheets, compliance manuals and other similar materials that meet the intent of this code.
The North Carolina State Building Codes do not include all additional requirements for buildings and structures that may be imposed by other State agencies, occupational licensing boards, and commissions. It shall be the responsibility of a permit holder, design professional, contractor, or occupational license holder to determine whether any additional requirements exist.
See the North Carolina Administrative Code and Policies.
Construction documents, technical reports and other supporting data shall be submitted in one or more sets with each application for a permit. The construction documents and technical reports shall be prepared by a registered design professional where required by the statutes of the jurisdiction in which the project is to be constructed.
Exceptions:
- The code official is authorized to waive the requirements for construction documents or other supporting data if the code official determines they are not necessary to confirm compliance with this code.
- Construction documents for energy code compliance are not required for one- and two-family dwellings and townhouses.
Construction documents shall be drawn to scale. Electronic media documents are permitted to be submitted where approved by the code official. Construction documents shall be of sufficient clarity to indicate the location, nature and extent of the work proposed, and show in sufficient detail pertinent data and features of the building, systems and equipment as herein governed. Details shall include, but are not limited to, the following as applicable:
- Insulation materials and their R-values.
- Fenestration U-factors and solar heat gain coefficients (SHGC).
- Area-weighted U-factor and solar heat gain coefficients (SHGC) calculations.
- Mechanical system design criteria.
- Mechanical and service water-heating system and equipment types, sizes and efficiencies.
- Equipment and system controls.
- Duct sealing, duct and pipe insulation and location.
- Air sealing details.
