Chicago is the region’s central city, an intensely developed urban environment where the great majority of land was platted generations ago. A plat of subdivision here overwhelmingly supports splitting or consolidating existing lots, re-platting a redevelopment site, or reconfiguring parcels for new construction rather than opening new ground. Genuinely new subdivisions of undeveloped land are rare in a city this fully built.
A plat of subdivision divides a parcel into lots, blocks, streets and easements in compliance with the municipality’s subdivision and zoning ordinances, then is recorded with the county. It is the foundation of any residential or commercial development.
The Pi Surveying process — clear, sealed, and ready for your project.
With roughly 2.7 million residents, Chicago is by far the largest municipality in Cook County and is not organized into townships, functioning as its own city government. Subdivision activity spans dense infill lot splits, assemblages for larger developments, and re-platting of former industrial or commercial sites across many neighborhoods. Any plat of subdivision must comply with the city’s subdivision regulations and zoning ordinance before approval. The approved plat is recorded with the Cook County Clerk’s Recordings Division, which merged the Recorder of Deeds into the Clerk’s office in December 2020, placing the new lots into the county land records used for deeds, financing, and permits.

It is a recordable plat that divides a parcel into lots, blocks, streets, and easements in compliance with municipal ordinances, recorded with the county so each lot exists as its own property.
