Property tax on a typical Park Ridge house
Our estimate for the median house in Park Ridge: about $12,600 a year (median 2025 assessed value $53,834). An appeal lowers the assessed value, which is one part of that bill; exemptions, the state equalizer and local tax rates are the others.
Our calculation from Cook County open data, not official figures and not your bill: 2025 final assessed value × the 2025 state equalizer × the 2025 tax rate of the home's tax code, minus the homeowner exemption, for 11,471 houses (classes 202–209, 234, 278).
