Welcome. The NIPC Development Database contains information on over 12,000 developments across the six-county northeastern Illinois region. NDD covers all significant land development and redevelopment for the full range of uses, including commercial, residential, public works, and more. Building on data collected since the system's inception in 1987, NDD is an important input to NIPC's long-range forecasting process.

NDD reflects input by NIPC staff and, increasingly, by local officials whose municipalities depend on this exhaustive, constantly updated database. It is maintained as a resource for communities, developers, and individuals who want information on regional development activity. Contact us with comments or suggestions.
