A building code
(also building control
or building regulations
) is a set of rules that specify the standards for constructed objects such as buildings and nonbuilding structures. The main purpose of building codes is to protect public health
, safety and general welfare as they relate to the construction and occupancy
of buildings and structures. The building code becomes law of a particular jurisdiction when formally enacted by the appropriate governmental or private authority.
Building codes are generally intended to be applied by architects, engineers, constructors and regulators but are also used for various purposes by safety inspectors
, environmental scientists, real estate developers, subcontractors, manufacturers of building products and materials, insurance companies, facility
managers, tenants, and others. Codes regulating the design and construction of structures where adopted into law.
Examples of building codes began in ancient times. In the USA the main codes are the International Commercial or Residential
], electrical codes and plumbing, mechanical
codes. Fifty states and the District of Columbia have adopted the I-Codes at the state or jurisdictional
In Canada, national model codes are published by the National Research Council of Canada.
