The binding land-use plan lays down legally binding rules for the development and organisation of sections of the municipal territory. It is developed on the basis of the preparatory land-use plan, but, unlike the latter, it creates direct rights and duties with regard to the utilisation of the sites within its purview. It can determine the category of use and degree of building coverage, type of development (open or closed), and lot coverage. It can also earmark sites for mitigation measures to offset intrusions, as well as sites for ancillary structures such as parking space and garages, vehicular and pedestrian infrastructure, and green spaces. Pursuant to the Land Utilisation Ordinance, the binding land-use plan can categorize land-use areas (for example as purely residential areas, general residential areas, mixed use areas, commercial areas, industrial areas). The degree of building coverage can be determined by setting the plot ratio, floor-space index, cubing ratio, height of structures, and number of full storeys. Permissible lot coverage can be set by means of building lines, set-back lines, or coverage depths.
Binding land-use plans also serve as the basis for other urban development activities provided for in the Federal Building Code, such as land reallocation, expropriation, and improvement. Plan preparation procedure is regulated in detail by the Federal Building Code. The binding land-use plan is adopted as a bye-law by the local council; it is therefore generally binding, also on private individuals. The binding land-use plan consists of a plan with legend, textual designations and information for the record, as well as an explanatory memorandum, including an environmental report. A special form of binding urban land-use planning is the project-based binding land-use plan. Such plans permit the municipality to grant permission for projects where, on the basis of a project and infrastructure plan agreed with the municipality, the project developer undertakes to complete the plan within a certain delay and fully or partly assumes planning and land improvement costs.
