How to verify zoning in Chicago.
Chicago zoning is set by Title 17 of the Municipal Code and mapped parcel by parcel in the city Zoning Map. Much of the city is covered by Planned Developments and Transit-Served Location provisions that change density and parking independently of the base district, so the district letter alone rarely settles what can be built.

How it works
Available data, one preliminary view.
Buildability geocodes the address, queries available flood, seismic, soil, radon, wildfire, and zoning context, and runs the published Buildability Score. Reports name the sources used and the items that still need local verification.

Does Buildability make the official zoning decision in Chicago?
No. Buildability organizes preliminary property context and links to local evidence.
What does the Buildability Score measure?
The preliminary score considers nine factors: zoning, flood, seismic, soil, radon, wildfire, utilities, terrain, and lot geometry. Availability and depth vary by address and source; City of Chicago remains the local authority for project-specific decisions.
