Question: How does the 2012 NC Mechanical Code and 2012 NC Residential Code correlate with the licensure requirements of the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors?

Answer: Section R409.5 of the 2012 NC Residential Code contains four prescribed methods of moisture control. The licensure requirement depends on the methodology chosen to control the humidity. Table 1: Humidity Control Method lists the four prescriptive methods for providing humidity control in a closed crawl space. Table 2: Licensure Requirement identifies which method requires an H-3 license. The licensure requirements are determined by the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors. The licensure question was posed to this Board and the response reprinted here for the convenience of the reader. If there are detailed questions concerning the licensure requirements, please contact the Board, at 919-875-3612.
