Common questions
How many parcels are in Union County, New Jersey?
JB PARCEL carries 149,394 parcel records for Union County, New Jersey, with owner information on 3 percent of them.
Can I find out who owns a property in Union County?
Not from us for Union County yet. We carry 149,394 Union County parcels with lot lines and location, but the county's published file carries owner names on fewer than 5 percent of parcels, so owner search finds few records here. Owner search works in the counties where we hold the field, and Union County does carry assessed values, recorded sales and year built.
How do I find vacant land or absentee owners in Union County?
We do not hold vacancy data for Union County yet, so this filter has nothing to match there. Vacancy filters work in the counties where we hold the field.
Can I search Union County by lot size or acreage?
Yes. Acreage is on 99 percent of Union 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.
