How many parcels are in Lake County, Illinois?
JB PARCEL carries 278,973 parcel records for Lake County, Illinois, with owner information on 99 percent of them.
Can I find out who owns a property in Lake County?
Yes. Search by owner name, address, or parcel number to pull the record: owner of record and mailing address and lot lines on the map.
How do I find vacant land or absentee owners in Lake County?
We do not hold vacancy data for Lake County yet, so this filter has nothing to match there. Vacancy filters work in the counties where we hold the field. Lake County does have owner mailing state: 716 parcels have an owner mailing address outside Illinois.
Can I search Lake County by lot size or acreage?
Yes. Acreage is on 91 percent of Lake County parcels, mapped from the parcel boundary, and the advanced search filters on it directly - set a minimum and maximum to pull every tract in that range, then stack vacancy or absentee ownership on top.
