The Department of Zoning and Land Use Planning (DZP) administers the City of Chicago's zoning code to ensure neighborhood land use designations serve the needs of residents, workers and visitors. DZP is also responsible for preparing community-based plans, preserving the city's architectural and historic landmarks, protecting its waterfronts, implementing sustainable development policies, and creating new public greenspaces. Department activities are coordinated through a wholistic planning process in cooperation with neighborhood representatives, sister agencies and other community stakeholders.
