In addition to the NC Building and Fire Code, fire departments in NC rely upon the NFPA Codes and Standards to guide them in the proper way to equip, maintain, and operate fire protection technology such as extinguishers, fire trucks, firefighting clothing, etc. Many of these codes are adopted into and referenced from the State Fire Code, as the NFPA itself is not a regulatory body nor enforcement agency. Each city and county may have its own selections of codes and standards it considers mandatory, so you should check with your local AHJ (authority having jurisdiction) to see which are in effect.
As of January 1, 2019 the Building and Fire Codes currently enforced in the State of North Carolina (2018 North Carolina Fire Code) is the 2009 International Fire Code with 2018 North Carolina Amendments. (This is also sometimes called the North Carolina State Fire Prevention Code) [Source: NC Office of the State Fire Marshal]
