Special Service Areas (SSAs)

A Special Service Area (SSA) is defined by Illinois State Statute as a contiguous area within a municipality or county in which special services are provided in addition to those services provided generally throughout the municipality or county. Special services include things like landscaping, advertising, public art, and extra garbage collections. The special services are paid from revenues collected from taxes levied or imposed upon property within that area.
