Decision Guide / 001Industrial / Flex / New Jersey Before You Lease or Buy an Industrial Building in New Jersey: What to Request Before Design Begins
A practical record-request and feasibility guide for owners, tenants, developers, and brokers evaluating warehouse, industrial, and flex property in New Jersey.
A lease can run sixty pages and still leave the most consequential questions about the building unanswered.
The listing may give you square footage, clear height, loading doors, parking, asking rent, and a few photographs. It describes the property being marketed. It does not establish that your use is allowed, that the existing building matches its record, or that the site and systems can support the operation you intend to put there.
That distinction matters before design begins—not after the lease is signed, the schedule is announced, and the first plan is drawn.
The purpose of an early property review is not to predict every problem. It is to assemble enough of the record to decide which questions belong to the building, which belong to the proposed operation, and which must be carried into the deal.
Start with the legal and municipal record
Ask for the current certificate of occupancy or other applicable occupancy documentation, prior planning and zoning resolutions, approved site plans, variances, open permits, violations, and any pending applications.
Do not treat these as interchangeable.
A zoning table can summarize the ordinance that applies today. A prior approval may contain conditions written specifically for that property. An approved site plan may establish parking, loading, circulation, landscaping, hours, or other features that cannot simply be rearranged because a new tenant wants a different layout.
The documented use matters as well. New Jersey's Uniform Construction Code states that a change in the use of a structure or portion of it requires prior application for and issuance of a certificate of occupancy. The state's Rehabilitation Subcode then governs construction requirements for work in existing buildings, including changes of use. That does not mean every new tenant creates a code change of use. It means the existing record and the proposed operation have to be compared before anyone assumes the answer.
The local zoning approval and the construction-code occupancy record answer different questions. You need both.
Establish what was approved, then establish what exists
Request the most recent boundary and topographic survey, architectural and engineering drawings, permit sets, approved revisions, closeout documents, and available inspection records.
Then label every document by what it actually is:
- approved: accepted by the authority having jurisdiction for a defined purpose;
- record: intended to show what was constructed or revised;
- existing-condition: measured or observed at a particular time;
- design: proposed, but not necessarily approved or built;
- marketing: prepared to describe the property, not verify it.
An old drawing can be valuable evidence. It is not an automatic instruction for new work.
Walls move. Equipment is replaced. Roof openings are patched. Sprinkler mains, electrical service, drainage, and structural members may differ from the drawings in the file. A plan marked “as-built” is still a document that should be compared with the building.
This is where a measured walk-through matters. The survey and drawings create a starting point; field verification establishes confidence.
Test the operation against the whole site
The first floor plan is often drawn too early.
Before laying out offices, racks, equipment, or production areas, write down how the property has to work on an ordinary day and on its busiest day:
- What vehicles arrive, how often, and at what time?
- Where do trucks turn, queue, load, and wait?
- Where do employees, visitors, and pedestrians enter?
- Where are refuse, outdoor storage, trailers, and deliveries expected to go?
- Are parking and loading spaces actually available to this tenant, or merely visible in an aerial image?
- What route remains for emergency access?
- Are there shared drives, easements, gates, or operating restrictions?
These movements compete for the same pavement. A site can have enough square footage and still fail the operation at its edges.
The proposed use should be drawn as a sequence of movements before it is treated as a collection of rooms.
At 13 Arlington, a current BLAST feasibility study begins with a 25-by-115-foot lot. The frontage has to accommodate an overhead door, a separate pedestrian entrance, the stair, structure, and the upper-floor window. None of those elements can be solved independently because all of them are competing for the same 25 feet. The proposed design is not built or approved, but the study makes the larger point visible: one property dimension can reorganize the entire project before the room layout begins.
Ask what the building can carry, supply, drain, protect, and exhaust
“Existing to remain” is not a systems analysis.
Request available information for the roof and structure, electrical service, gas, water, sanitary and storm systems, fire protection, fire alarm, heating and ventilation, utility accounts, maintenance, and recent inspections. Pair that information with the actual demands of the proposed operation.
The useful questions are specific:
- Is the published clear height measured below structure, sprinklers, lights, or another obstruction?
- Can the slab and structure support the proposed equipment, storage, rooftop units, or penetrations?
- Is electrical capacity documented at the service, or merely repeated from a listing?
- Does the sprinkler system match the intended storage arrangement and commodity?
- Where can new exhaust, intake, drainage, or utility work physically go?
- What equipment is near the end of its service life, and who is responsible for it?
The answer may require an architect, engineer, fire-protection consultant, contractor, utility, or property-condition professional. The early review does not replace those investigations. It tells the team which investigations are needed before the schedule depends on an assumption.
Use environmental and flood information as screening, not a verdict
New Jersey provides several useful public tools. NJ-GeoWeb allows a user to view and query environmental map layers. NJDEP's DataMiner and DocMiner provide access to facility, site-remediation, permitting, compliance, enforcement, and other available records. The Department's records office also accepts requests for environmental due-diligence records.
These sources can reveal a question. They do not close it.
NJDEP warns users to understand the accuracy limits of the data layers. A mapped point may be approximate. A clean-looking map is not the same as a Phase I Environmental Site Assessment, file review, subsurface investigation, or opinion from an environmental professional.
Flood review has a similar boundary. FEMA's Map Service Center is the official public source for National Flood Insurance Program flood-hazard information and provides effective maps, studies, and related products. It is an essential first screen. It does not tell you how water actually moves across a particular site, whether drainage infrastructure is adequate, or what a lender, insurer, municipality, or project design will require.
Use the public record to identify the next question—not to manufacture certainty.
Put the unresolved questions into the transaction
Some answers will not be available before a letter of intent or draft lease. That does not make them irrelevant. It makes them deal terms.
The owner, tenant, broker, attorney, architect, engineers, and contractors should be able to see which items are:
- verified;
- represented by another party;
- still under investigation;
- assigned to landlord work or tenant work;
- dependent on an approval, permit, utility, or third party;
- likely to affect rent commencement, access, cost, or occupancy.
The architect should not draft the legal language. The attorney should not be asked to determine whether the roof can support new equipment. Each discipline should make its question visible early enough for the appropriate person to answer it.
The record to request
At minimum, assemble the following before design depends on the property:
Property and approvals
- current boundary and topographic survey;
- deed, title exceptions, easements, and shared-access agreements;
- current zoning information and any formal zoning determination obtained for the proposed use;
- prior planning or zoning resolutions and conditions;
- approved site plans and amendments;
- current certificate of occupancy or other applicable occupancy documentation;
- open permits, violations, orders, and pending applications.
Building and systems
- architectural, structural, civil, mechanical, electrical, plumbing, and fire-protection drawings;
- record drawings, approved revisions, and closeout documents;
- roof reports, warranties, repair history, and leak records;
- structural or slab reports and known load limitations;
- fire-sprinkler and fire-alarm inspection records;
- utility service and capacity information;
- equipment schedules, maintenance records, and recent condition assessments.
Site and environmental
- environmental reports, remediation documents, restrictions, and correspondence;
- flood maps, elevation information, drainage studies, and known flood history;
- geotechnical reports and underground-utility information when available;
- pavement, loading, retaining-wall, or site-structure reports when relevant.
Operation and transaction
- a written description of the proposed use and process;
- staffing, shifts, visitors, parking, deliveries, truck types, loading frequency, storage, equipment, utilities, and waste assumptions;
- draft lease or purchase agreement, work letter, responsibility matrix, access provisions, milestones, contingencies, and target occupancy date.
You will not receive every item on the first request. The missing documents are part of the result. They identify where the team is relying on field verification, a new study, another party's representation, or an unresolved risk.
BLAST's Project Desk organizes this first review into property questions, document requests, and a brief you can print or copy. It is free to use, requires no account, and does not save or send what you enter.
The point is not to make a property perfect before proceeding. It is to know what the property is asking of the project before the project is committed to it.
