Why Union County Is a Premier Industrial Buying Market in Northern NJ
Union County, NJ holds a unique position in the Northern New Jersey industrial real estate market. The county sits at the confluence of the state's most critical logistics infrastructure: the Port of Newark/Elizabeth - the busiest container port complex in the northeastern United States - lies at Union County's northeastern boundary in Elizabeth and Linden. Newark Liberty International Airport's cargo facilities sit immediately adjacent. The New Jersey Turnpike, I-78, the Garden State Parkway, and Route 22 all intersect within the county, creating unmatched highway connectivity.
For buyers of industrial real estate, this infrastructure concentration creates a fundamental demand driver that has historically supported strong occupancy, competitive lease rates, and long-term value appreciation for Union County industrial assets. This guide provides a practical framework for businesses and investors evaluating industrial property purchases in Union County in 2026.
What Are the Key Industrial Submarkets for Buyers in Union County?
Elizabeth is the anchor of Union County's industrial market and one of the most sought-after logistics addresses in New Jersey. The Elizabeth industrial corridor along Route 1/9 and the Turnpike's Exit 13 interchange cluster serves port importers, customs brokers, freight forwarders, third-party logistics operators, and distribution companies that require immediate access to container traffic from the Port of Newark/Elizabeth. Industrial sale prices in Elizabeth reflect this premium, with quality buildings frequently trading at $180 to $280 per square foot.
Linden, immediately south of Elizabeth, serves similar port-dependent users with slightly more suburban industrial character and additional available land for new development. The Linden airport (Linden Airport / SBJ) and the adjacent industrial corridors along Route 1/9 and I-278 make Linden a strong secondary market to Elizabeth for port-connected businesses.
The Route 22 corridor through Hillside, Union, Springfield, and Mountainside represents Union County's suburban industrial tier - generally featuring older building stock at more moderate prices compared to the Elizabeth-Linden cluster. Clark, Kenilworth, and Rahway along the eastern and southern portions of the county offer established industrial parks with good highway access to both the Turnpike and I-287 networks.
What Price Ranges Should Buyers Expect in Union County?
Industrial property sale prices in Union County in 2026 span a wide range based on location, building class, and specifications. Elizabeth's port-proximate industrial market sits at the premium end, with quality warehouse and distribution facilities trading at $180 to $280 per square foot. These premium prices reflect the irreplaceable location advantages and strong institutional demand for port-adjacent industrial assets.
Suburban Union County industrial buildings - in Clark, Kenilworth, Springfield, and similar communities - typically trade at $120 to $200 per square foot for owner-user quality product, with older or lower-specification buildings available at the lower end of this range. Multi-tenant flex and light industrial condominiums offer entry-level buying opportunities in some Union County business parks at $100 to $150 per square foot for well-maintained units.
Investment-grade multi-tenant industrial properties in Union County command pricing based on their net operating income and cap rate rather than pure price-per-square-foot metrics. Cap rates for stabilized Union County industrial assets have compressed in recent years as institutional capital has pursued the Northern NJ market; current cap rates for quality net-lease industrial assets in Union County typically range from 5.5 to 7 percent depending on building quality, tenant credit, and lease term remaining.
What Environmental and Physical Due Diligence Is Essential in Union County?
Union County's industrial history is extensive, and environmental due diligence is a non-negotiable component of any acquisition in this market. Elizabeth in particular has significant historical industrial contamination, with numerous properties subject to NJ DEP oversight programs and prior Superfund designations. A Phase I Environmental Site Assessment is the minimum starting point for any Union County industrial purchase; Phase II sampling is frequently warranted based on Phase I findings.
Physical inspection priorities in Union County industrial buildings include roof condition, structural integrity of loading docks and dock aprons, electrical service capacity (particularly for heavy manufacturing or freezer/refrigeration uses), HVAC system condition, and the condition of any existing tenant improvements. Older Elizabeth warehouse buildings, many built in the mid-20th century, may require significant capital investment to bring mechanical systems to modern standards.
How Does the 1031 Exchange Strategy Apply to Union County Industrial Purchases?
Union County industrial properties are frequently targeted by 1031 exchange buyers - investors reinvesting proceeds from the sale of appreciated real estate to defer capital gains taxes. The county's strong logistics fundamentals, stable tenant demand from port and airport-connected users, and competitive cap rates relative to coastal industrial markets make Union County industrial assets attractive replacement properties for exchange buyers.
