  • Documented economic hardship without incentive
Where it applies

Cook County Class 6b SER (Sustainable Emergency Relief) is administered at the county level. Depending on the program, eligibility may depend on the specific location, property type, or business activity rather than a single drawn boundary.

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.
