International Zoning Code (IZC)
Building codes are regulations that set out the standards to which buildings and other structures must conform. The International Zoning Code (IZC) was established in the US by the International Code Council (ICC) and is applied by most of the country’s jurisdictions as well as internationally, although it can be amended to reflect local conditions and legislation.
The International Zoning Code (IZC) is a model code that regulates minimum zoning requirements for new buildings. It is intended to provide for the arrangement of compatible buildings and land uses and establish provisions for the location of all types of uses, in the interest of the local area. It aims to promote uniformity and consistency in zoning for planners, code officials and developers.
Zoning is the process of dividing a particular area of land into different districts or zones and specifying certain uses (i.e. residential, commercial, industrial) which can be permitted or prohibited for each. Zoning is carried out by the relevant municipality or county, and segregates uses that are considered to be incompatible, as well as guiding urban growth and development.
