Urban planning law, or "droit de l'urbanisme" in French, governs the development, use, and management of land and buildings within urban and rural areas. It establishes the legal framework for zoning, land use, building permits, environmental impact assessments, and public infrastructure development. The goal of urban planning law is to ensure orderly and sustainable development, balancing economic growth, environmental protection, and the quality of life for residents. It also regulates the roles and responsibilities of public authorities and private entities in shaping the built environment.
