I agree with this:
It's important to note the difference between a code and a model code such as the International Building Code (IBC). A model code is developed by a standards organization, typically using the voluntary consensus standard process and subject matter experts. The intent of a model code is to have an industry-wide standard that can be adopted and customized by local jurisdictions, thereby saving the jurisdiction the time and expense of developing and maintaining their own code.
According to the National Institute of Standards and Technology (NIST) Circular No. A-119, Revised, a standard is "[t]he definition of terms; classification of components; delineation of procedures; specification of dimensions, materials, performance, designs, or operations; measurement of quality and quantity in describing materials, processes, products, systems, services, or practices; test methods and sampling procedures; or descriptions of fit and measurements of size or strength.
A code is a standard that has been enacted into law by a local, regional, or national authority having jurisdiction so that the engineer or contractor is legally obligated to comply with the code. Noncompliance can result in being prosecuted. The code may be an industry, government, or voluntary consensus-based standard. A code can include references to standards, which means the standards are incorporated by reference and therefore are part of the code and legally enforceable.
