Cook County Records is a property research and public-records service focused on Park Ridge, Illinois, with parcel coverage in Wilmette, Winnetka, Glencoe and Kenilworth. It connects property sales, building permits, assessment histories, town records and recorded obligations so homeowners, buyers and businesses can explore a property’s history and the public records behind it. Homeowners can use a free assessment check to compare a property’s assessed value per square foot with similar homes, purchase a sourced appeal brief for $49 when eligible, or review published town records before buying.

The service also provides parcel maps and property searches by address or PIN. For businesses, offerings include town-specific appeal and contractor lead lists from $299, an Intelligence Desk subscription with live feeds and commercial-use lists, and a pre-sale commercial API. Its research also examines local meeting records, public money, plans and policy findings, with sources shown for each finding.

The service describes its comparisons as screening tools, not appraisals, and its property-record checks as distinct from title searches
