Construction codes refer to a set of standards and guidelines that govern the design, construction, and maintenance of buildings and other structures. These codes are established by various organizations such as the International Code Council (ICC), the American Society of Civil Engineers (ASCE) or state and local building departments. The purpose of these codes is to ensure public safety, health, and welfare in the design and construction of buildings and structures. They cover a wide range of topics including structural integrity, fire safety, accessibility for people with disabilities, energy efficiency, and plumbing and electrical systems. Violations of these codes can result in fines or other penalties.
