Search Union County, NJ Property Records

In Union County, New Jersey, the County Clerk handles legal documents that alter property ownership or obligations, including deeds, mortgages, liens, foreclosures, cancellations, and map filings. To make specialized property data accessible to local communities, municipal offices maintain tax maps, property assessments, zoning ordinances, and site plans.

Researchers in Union County, NJ, dig into property history using online databases, in-person visits, or formal Open Public Records Act (OPRA) requests.

For quick record retrieval, users leverage the Assessment Records Search portal to identify current ownership, assessed values, and recent sales history. Researchers typically use unique identifiers such as block and lot numbers, street addresses, or owner names to obtain these MOD IV tax lists.

To verify the legal standing of a property, individuals can use the Online Public Land Records Search Page to locate and examine mortgages, liens, or deeds. When a title search stretches back into the early 20th century, individuals must visit the Union County Clerk’s Office.

Meanwhile, Open Public Records Act (OPRA) requests target localized records that are not always available on countywide portals, such as site plan approvals and zoning violation notices.

Union County must comply with Daniel’s Law, which redacts the home addresses of certain public officials, such as judges and law enforcement, from online databases. This can create gaps in ownership history that make it difficult to establish a clear chain of title for specific properties.

While public lists redact current information for privacy, PropertyChecker may cross-reference archived tax lists and older deed transfers from before the redactions took place. Retrieving these historical records provides a clear chain of title and a complete transaction history.

Property Ownership and Title Information

Using the Union County Clerk’s Online Public Land Records Search Page, researchers can efficiently verify property ownership history and confirm the legality of transfers. Specifically, they should look for deeds that include vital ownership details, including the current owner (grantee), the previous owner (grantor), and the transfer date.

Property Sales and Transaction History

Official overviews of property transactions, including sale prices, transaction dates, and non-usable codes, can be obtained via the Assessment Records Search portal provided by the Union County Board of Taxation.

Non-usable codes are critical. For instance, the sales record might show a 2024 sale for $550,000 (Class 2), with a non-usable code. This indicates that it was an inter- family transfer, and the sale price does not reflect the true market value. However, if the code is blank, it was a normal "arm's length" transaction.

Navigating the Assessment Records Search portal requires technical knowledge of interpreting non-usable codes. PropertyChecker eliminates this complexity.

The platform can synthesize sales and transaction data from multiple databases and enable users to quickly determine whether the property was transferred through a normal "arm's length" transaction or a special transaction.

Property Tax Assessment and Payment Records

Each of Union County’s municipalities has its own assessor who determines the “true market value” of properties as of October 1 of the pre-tax year. These appointed officials work in coordination with local tax collectors and the Union County Board of Taxation to ensure taxation is applied fairly, consistently, and efficiently across the county.

To track assessed values, tax rates, tax bills, exemptions, and deductions, individuals can use the Assessment Records Search portal available on the Board of Taxation’s official website.

Property owners with contested assessments of $1,000,000 or less may file a formal appeal with the Board of Taxation.

Property Characteristics and Parcel Details

The Union County Board of Taxation’s Assessment Records Search portal provides official, state-mandated assessment data, including property characteristics and parcel details. The portal allows users to search for parcels by owner name, property location, or block and lot.

After submitting a search, individuals may view details such as land size, number of rooms or stories, and construction type.

Zoning, Land Use, and Planning Records

Individuals seeking zoning ordinances, official zoning maps, master plans, and variance applications should contact the municipal government for the property’s specific location.

In the Township of Union, researchers can verify a property’s zoning classification by reviewing the Township Zoning Map or by contacting the Zoning Office via phone or email.

Meanwhile, the Union County Planning Board and the Union County Bureau of Planning and Land Use hold records of site plans, development applications, and subdivisions that affect county roads, drainage systems, or public facilities.

Legal Documents Affecting Property

The Union County Clerk’s Office implements the Online Public Land Records Search Page for the public to access property-impacting legal documents instantly.

The site contains indexed information associated with deeds, liens, mortgages, releases, discharges, easements, inheritance tax waivers, and other real estate instruments recorded from June 1, 1977, to March 20, 2026.

To find digital land records and documents, researchers should input the grantor/grantee name, date range, instrument number, or book and page number.

Building Permits, Inspections, and Construction Records

Construction records in Union County, including permits, inspection results, and code violations, are available at local municipal construction offices.

For example, residents in the Town of Westfield can consult the Building Department to confirm whether the design and construction of residential and non-residential structures comply with the New Jersey Uniform Construction Code (UCC).

Many municipalities implement online portals for tracking permit status, inspector notes, and technical construction specifications. If no online portal exists, individuals must submit an Open Public Records Act (OPRA) request through the municipal clerk's office.

Maps and Visual Property Data

Union County municipalities often maintain their own GIS platforms, which make it easier for residents and researchers to access maps and visual property information. For example, the Union Township GovPilot Interactive GIS Map displays property lines and building footprints.

Individuals can also use state-level GIS tools, such as the Property Explorer App managed by the New Jersey Office of GIS (NJOGIS). This app provides historical aerial imagery for tracking land changes over time.

Within the county’s more than 102-square-mile land footprint, there are over 149,000 parcels.

The registrar of deeds in Union County, NJ, is the County Clerk’s Office. This office files and preserves official records, including deeds, mortgages, mortgage cancellations, assignments, discharges, releases, foreclosures, federal tax liens, and UCC filings.

The Union County Sheriff’s Office uses recorded federal tax liens when conducting sheriff’s sales related to delinquent properties. Before proceeding with a foreclosure sale, the Sheriff’s Office must identify and account for these liens. This ensures proper notice is given and that proceeds from the sale are distributed in accordance with lien-priority laws.

Digital land records are accessible through the Online Public Land Records Search Page. To request certified copies of documents, either online or by mail, users can select the “Request Certified Copy” link located near each record.

The fee for certified copies is $8 for the first page, with each additional page costing $2. For documents recorded before 1977, individuals may need to visit the County Clerk’s Record Room at its Elizabeth main office or Westfield satellite location.

Union County comprises 21 distinct incorporated municipalities. These include a mix of cities, townships, boroughs, and a town (Westfield).

Such municipalities hold records detailing the day-to-day use, tax valuation, and physical characteristics of property. Municipal clerks, tax assessors, building departments, and planning or zoning boards typically manage these localized records.

For properties formerly used for industrial purposes, the municipal clerk may hold Remedial Action Workplans (RAW) or New Jersey Department of Environmental Protection (NJDEP)-approved "No Further Action" letters. These documents record the cleanup of underground storage tanks (USTs) or contamination.
