NJ Home Inspection: What Buyers and Sellers Need to Know

July 2026  ·  9 min read  ·  By Joe Tumminaro

The home inspection is one of the most consequential steps in any New Jersey real estate transaction — and one of the most misunderstood. Buyers sometimes treat the inspection report like a punch list of demands. Sellers sometimes treat it like an attack. Neither approach serves you well.

Here's what actually happens during an NJ home inspection, what to watch for, and how to handle the negotiation that follows.

What a Home Inspector Actually Does

A licensed home inspector does a visual examination of the property's major systems and structure. They are not engineers, and an inspection is not a guarantee — it's an informed assessment of what can be seen on the day of the inspection.

A standard NJ home inspection covers:

Roof

Condition of shingles, flashing, gutters, downspouts, and visible decking from the attic.

Foundation & Structure

Cracks, water intrusion, settlement, and structural framing in the basement or crawl space.

Electrical

Panel condition, wiring type, grounding, GFCI outlets in wet areas, visible hazards.

Plumbing

Water pressure, drain flow, visible pipe condition, water heater age and function.

HVAC

Furnace and AC operation, filter condition, ductwork, age of equipment.

Interior

Windows, doors, floors, walls, ceilings, visible insulation, attic ventilation.

What a standard inspection does NOT include

Radon testing, oil tank sweeps, mold testing, sewer scopes, chimney inspections, and well/septic testing are separate add-ons — each costs extra but may be worth it depending on the property and age of the home.

NJ-Specific Inspection Concerns

New Jersey's housing stock is older than most states. Homes built before 1978 may have lead paint. Homes with older HVAC systems often have asbestos pipe wrap in the basement. Underground oil tanks — both active and abandoned — are common in many NJ towns.

Oil tank sweeps

If the home was ever heated with oil or if you see evidence of a past oil tank (fill pipes, vent pipes, or oil-fired equipment in the basement), get an oil tank sweep. An abandoned tank that leaked can cost $20,000–$100,000+ to remediate, and the liability follows the property — not the seller, once you close.

Radon testing

New Jersey has elevated radon levels in many counties, particularly in the northwest. Radon is the second leading cause of lung cancer in the US. Testing costs about $150–$200; mitigation if levels are high runs $800–$1,500. Always test.

Sewer scope

For homes built before 1970, consider a sewer scope — a camera run through the main sewer line to check for root intrusion, collapsed sections, or old clay pipe that's failing. A sewer line replacement can run $5,000–$15,000. The inspection costs about $200–$350.

The Inspection Report

Expect a detailed PDF report — often 50–100 pages — with photos, findings categorized by severity, and recommendations. Inspectors typically flag items as:

A 300-page inspection report on a 1960s colonial is not a disaster — it's normal. The question is whether there are major defects that weren't disclosed or weren't priced into the deal.

Red Flags That Can Kill a Deal

Active water intrusion in the basement

Surface dampness is one thing. Active water coming in through walls or floor drains is another. Waterproofing systems can be installed, but costs vary widely and the underlying cause matters.

Knob-and-tube or aluminum wiring throughout

Older wiring types can present insurance problems and rewiring an entire house is expensive. Some insurers won't write policies on homes with knob-and-tube wiring.

Roof at or past end of life

A roof that needs immediate replacement is a known quantity — budget $12,000–$25,000 for an average NJ home. The issue is when the condition is ambiguous and both parties disagree on remaining life.

Foundation cracks with active movement

Hairline cracks are common in NJ's older homes. Horizontal cracks in block foundations, or cracks with displacement, are structural concerns requiring an engineer's assessment.

How to Negotiate After the Inspection

For buyers

Be strategic about what you ask for. Requesting 30 line items from the inspection report signals that you'll be difficult to work with and often results in less cooperation from the seller. Focus your requests on:

You can ask for repairs, a credit at closing, or a price reduction. Credits are often preferable — they let you control the work after closing rather than hoping the seller uses a quality contractor.

For sellers

You don't have to agree to everything in an inspection request, but being reasonable preserves the deal. Consider:

NJ Tip

In New Jersey, the inspection contingency is typically negotiated during attorney review — your attorney handles the back-and-forth, not the agents. Make sure your attorney is responsive and experienced with inspection negotiations.

Pre-Listing Inspections for Sellers

One of the best things a seller can do is hire their own inspector before listing. This costs $400–$600 and gives you time to fix issues on your schedule, at prices you control, before a buyer uses them as leverage. It also signals transparency — buyers appreciate knowing you've already had the house inspected.
