NMHC/NAA are actively involved in the development of model building codes and standards to ensure that the unique needs of multifamily construction are considered and that proposed changes to codes and standards do not unnecessarily undermine the affordability and availability of housing.
While there are a number of building code and standard-setting organizations, the most widely-used set of codes and standards is developed by the International Code Council (ICC). The ICC family of codes and standards provide minimum requirements for all facets of multifamily construction, including structural and mechanical systems, energy efficiency, plumbing, fire safety, accessibility and sustainability, and often serve as the basis for code requirements adopted at the state and local levels.
The ICC national model codes are updated every three years according to a detailed development process and timeline. While the process is open to the public and allows for participation by interested stakeholders, final approval of new code editions is made by government code and safety officials.
