Published criteria — confirm with City of Chicago Department of Planning and Development — Historic Preservation

  • Property must be in a Chicago-designated Landmark District
  • Historically significant building undergoing rehabilitation
Where it applies

Chicago Landmark District Incentives is screened against the Chicago Landmark District boundary. A geocoded point that intersects that boundary is a location signal, not a determination — review the current program source for the boundary's role and any remaining criteria. A single address can fall inside several overlapping incentive boundaries at once.

Boundaries are precise and change over time, so whether a specific address falls inside a mapped zone always depends on that exact address. The fastest way to check is to run a free snapshot for the parcel you have in mind — mapped coverage is a location signal, not an eligibility determination.
