Portions of editions of the California building codes are published by the International Code Council (ICC), National Fire Protection Association (NFPA), International Association of Plumbing and Mechanical Officials (IAPMO), and BNi Building News.^[1] As they are, in effect, amended versions of copyright works such as the International Building Code (IBC) maintained by the International Code Council (ICC), the regulations have substantial portions under copyright, and hence may be withheld from the public or individuals, but still have the force of law. In 2008, Carl Malamud published the California Building Standards Code on Public.Resource.Org for free.^[4]
