Building Codes: A set of regulations that govern the design, construction, alteration, and maintenance of structures. Building codes are created to ensure the safety and welfare of building occupants and the public by providing a minimum standard for buildings and other structures. They can include requirements such as fire resistances ratings, electrical wiring protection, ventilation, indoor air quality, egress, and many other topics. Building codes provide important guidelines for architects, engineers and contractors in their efforts to construct safe and functional facilities.
