Where We Build: Warren County Towns We Serve
Warren County blends a fast-growing logistics economy with agricultural and riverfront communities, and we work across all of them. Our service area includes:
- Phillipsburg – the county’s largest town, a historic Delaware River industrial center at the foot of Interstate 78;
- Hackettstown – home to the Mars manufacturing operation, Hackettstown Medical Center, and Centenary University;
- Washington Borough & Washington Township – commercial and industrial centers along Route 31 and Route 57;
- Greenwich, Mansfield, Lopatcong & Pohatcong – the I-78 and I-80 warehouse and distribution corridor;
- Belvidere & the rural townships – the county seat and the agricultural communities along the Delaware.
From a distribution facility along I-78 to a medical office in Hackettstown or a retail buildout in Washington, Warren County’s commercial construction spans heavy logistics, manufacturing, healthcare, and town-center work—each with its own demands and rules.
Commercial Sectors We Build in Warren County
Warren County’s logistics- and manufacturing-driven economy supports a wide range of commercial construction, and Plescia delivers across its major sectors:
- Industrial, warehouse & logistics – the county’s defining growth sector, with major distribution development along Interstates 78 and 80;
- Manufacturing & food production – production and facility work reflecting the county’s manufacturing base, including its food-industry legacy;
- Healthcare & medical – outpatient centers and medical offices tied to Hackettstown Medical Center, Atlantic Health System, and St. Luke’s in Phillipsburg;
- Retail & restaurant – buildouts along the Route 22, Route 57, and Route 31 corridors;
- Corporate office & institutional – office, educational, and civic facilities, including work serving Centenary University;
- Mixed-use & town-center – redevelopment in Phillipsburg, Hackettstown, and the county’s historic downtowns.
Each of these building types carries its own engineering, compliance, and logistics demands, and our experience across the full range is what lets us match the right approach to the right project.
Project Types We Deliver
Owners come to us for the full spectrum of commercial construction delivery, including:
- Ground-up construction of new commercial, industrial, and mixed-use buildings;
- Warehouse, distribution & light-industrial construction along the county’s interstate corridors;
- Interior fit-outs and tenant improvements for office, retail, medical, and restaurant tenants;
- Manufacturing and production-facility work, including renovations and expansions;
- Renovations and repositioning of existing commercial and town-center space;
- Fast-track delivery for competitive openings and time-sensitive industrial occupancy.
Whether the work is a full ground-up build or a fast-track interior fit-out in an occupied building, we manage it as a single point of accountability from preconstruction through closeout.

The I-78 & I-80 Logistics Corridor
Warren County has become one of the Northeast’s most active distribution markets, as developers build large warehouse and logistics facilities along Interstates 78 and 80 to serve the New York and Philadelphia metros from a lower-cost western position. This growth defines the county’s construction economy: big-box distribution centers, light-industrial and last-mile facilities, and the site, traffic, and utility work that comes with them. Building here means managing large-footprint sites, significant earthwork and stormwater systems, heavy truck-access and traffic planning, and coordination with NJDOT and local officials on major road frontage. Our experience delivering complex, schedule-driven commercial work translates directly to the demands of Warren’s logistics corridor.

Phillipsburg, Hackettstown & the Town Centers
Alongside its logistics growth, Warren County’s established towns carry a steady base of commercial construction. Phillipsburg, the county’s largest community, pairs a historic Delaware River industrial heritage with riverfront redevelopment and the St. Luke’s healthcare presence. Hackettstown anchors the eastern county with the Mars manufacturing operation, Hackettstown Medical Center, and Centenary University, driving healthcare, institutional, and retail work. Across these centers, projects mean working within established downtowns, coordinating with smaller municipal offices, and respecting the historic character of riverfront and town-center districts. Our experience across healthcare, institutional, and town-center work complements the heavy industrial activity defining the county.
Local Regulations, Permitting & Logistics in Warren County
Successful delivery in Warren County depends on understanding the layers of review every commercial project passes through:
- The New Jersey Uniform Construction Code (UCC), enforced by each municipality’s construction official across the building, electrical, plumbing, and fire subcodes, with a Certificate of Occupancy issued only after final inspections;
- Municipal Planning and Zoning Boards, plus county and NJDOT review for the major site-access and traffic work that large industrial projects require;
- The New Jersey Highlands, whose planning area reaches into eastern Warren County and adds environmental constraints;
- NJDEP review for wetlands, flood hazard areas along the Delaware and its tributaries, stormwater, and any site remediation—central to large warehouse sites;
- Agricultural and farmland-preservation considerations in the county’s rural townships.
Just as important are the logistics of building in the county: large-site earthwork and staging, heavy truck access and traffic coordination, utility lead times with JCP&L and local authorities, and access planning around Interstates 78 and 80 and Routes 22, 31, and 57. We build these realities into the schedule during preconstruction rather than discovering them in the field.

Frequently Asked Questions
What towns in Warren County does Plescia serve?
We serve all of Warren County, including Phillipsburg, Hackettstown, Washington, Belvidere, Greenwich, Mansfield, Lopatcong, and Pohatcong, along with the rural townships and the Interstate 78, Interstate 80, Route 22, Route 31, and Route 57 corridors that run through the county.
Does Plescia build warehouse and distribution facilities in Warren County?
Yes. The Interstate 78 and Interstate 80 corridors have made Warren County one of the Northeast’s fastest-growing logistics markets, and warehouse, distribution, and light-industrial construction are a core part of the county’s commercial activity. That work means managing large-footprint sites, significant earthwork and stormwater systems, heavy truck-access and traffic planning, and coordination with NJDOT and local officials—demands our schedule-driven experience is built to handle.
What types of commercial projects does Plescia build in Warren County?
We deliver across industrial, warehouse, and logistics, manufacturing and food production, healthcare and medical, retail, restaurant, corporate office, institutional, and mixed-use town-center work. Project types range from ground-up industrial and commercial construction to interior fit-outs, manufacturing and production work, renovations, and fast-track tenant improvements.
Does Plescia serve the Hackettstown and Phillipsburg areas?
Yes. Hackettstown and Phillipsburg are Warren County’s two largest commercial centers. Hackettstown anchors the eastern county with its manufacturing base, Hackettstown Medical Center, and Centenary University, while Phillipsburg pairs a historic Delaware River industrial heritage with riverfront redevelopment and healthcare. We deliver healthcare, institutional, retail, and town-center work across both.
What should owners know about permitting and regulations in Warren County?
Commercial projects follow the New Jersey Uniform Construction Code and are permitted and inspected by each municipality’s construction official, with approvals often requiring Planning Board and Zoning Board review—and, for large industrial sites, county and NJDOT review for traffic and access. Eastern Warren County reaches into the New Jersey Highlands planning area, and sites along the Delaware and its tributaries involve NJDEP review for wetlands, flood hazard areas, and stormwater. Engaging the right officials early and submitting complete, coordinated documents is the most effective way to keep approvals on schedule.
