Union County
Start with the geography, then narrow to the address
A Union County statistic is regional context. It does not describe every municipality, neighborhood label, property type, or individual address.
Municipality or locality
Confirm the legal municipality. A postal or neighborhood name may sit inside a differently named municipality with different records.
Property
Verify the parcel, assessment, permits, condition, disclosures, and genuinely comparable sales for the address itself.
Research
Five source checks that answer different questions
Market reports
Select the county, reporting period, and available property category. Do not reuse county figures as town-level facts.
Property-tax records
Read the state table labels and the current municipal record. An average is not a parcel's bill or a valuation.
District reports
Search the state report system, then confirm the current district and attendance assignment for the specific address.
Transit
Test the actual origin, destination, departure time, transfers, and current service notices in NJ TRANSIT's tools.
Place identity
Use state and county directories to distinguish a legal municipality from a locality, postal name, or informal neighborhood label.
