Who it's for

Property owners in Chicago-designated landmark districts who are rehabilitating historically significant buildings. Both commercial and residential properties may qualify.

Where it applies

Chicago Landmark District Incentives is tied to the Chicago Landmark District geography — being inside that boundary is the first eligibility gate. A single address can fall inside several overlapping incentive areas at once.

Boundaries are precise and change over time, so exact eligibility always depends on the specific address. The fastest way to know is to run a free snapshot for the parcel you have in mind.
