Land is allocated and private activities are coordinated with public facilities by means of zoning ordinances and subdivision regulations. A zoning ordinance governs how the land may be used and the size, type, and number of structures that may be built on the land. All land within a city is divided into districts, or zones. In these districts certain land uses are allowed by right, and general restrictions on building height, bulk, and use are specified. The zoning regulations carry out the land allocations recommended in the comprehensive plan. Specific locations are given for different types of residences, industries, and businesses. Specific numbers are given for allowable heights of buildings, coverage of a lot, and density. Allowable land uses are specified for each zone, including special conditions such as required off-street parking. Most regulations are termed “matter-of-right”; if the specified requirements are met a permit will be given. Other regulations provide general standards with considerable flexibility in the mixture of building uses or the building design. These require more extensive review before approval.
The conversion of raw land (construction on previously undeveloped land) is controlled by subdivision regulations and by site-plan review. These ordinances establish standards of land development by regulating such features as roadway width, drainage requirements, traffic circulation, and lot sizes. Subdivision regulations and site-plan review guide orderly development, protect prospective and current residents from poorly designed buildings or business districts, and ensure that most of the costs of land conversion are borne by those who will benefit from the development, that is, by the developer and the future residents.
Building and housing codes govern the quality and safety of construction of new buildings, as well as subsequent maintenance. In most instances, the codes specify the materials to be used, their minimum quality, and the building components necessary in a structure that is suitable for human occupancy. (1)
