Home Inspection Guide
Northern New Jersey Real Estate
The home inspection is one of the most important steps in any NJ home purchase. This guide explains what inspectors evaluate, which specialty inspections matter in NJ, and how to use the results.
For informational purposes only. Hire a licensed NJ home inspector and consult your real estate attorney regarding inspection contingencies and negotiation options.
What a Standard Home Inspection Covers
A licensed NJ home inspector conducts a visual examination of the home's major systems and components.
Roof
Age, condition, missing or damaged shingles, flashing around chimneys and skylights, gutters and downspouts, signs of water intrusion or improper drainage.
Foundation & Structure
Cracks in foundation walls, evidence of settling or movement, structural integrity of beams, joists, and framing, signs of moisture intrusion in the basement or crawlspace.
HVAC Systems
Age and condition of furnace, boiler, air conditioning, and ductwork. Whether filters are clean, whether systems heat and cool effectively, carbon monoxide detector placement, and estimated remaining useful life.
Plumbing
Water pressure, drain function, water heater age and condition, pipe materials (especially in older NJ homes where galvanized or lead pipes may be present), visible leaks, and sewer line function.
Electrical System
Panel amperage and age, condition of wiring, presence of GFCI outlets in wet areas, grounding, any double-tapping of breakers, aluminum wiring (common in some 1960s–1970s NJ homes), and smoke/CO detector placement.
Exterior
Siding condition, grading and drainage around the foundation (critical in NJ where basement water intrusion is common), deck and porch structure, driveway, walkways, and retaining walls.
Insulation & Ventilation
Attic insulation levels, proper ventilation in attic and crawlspace to prevent moisture buildup and ice dams, insulation in exterior walls.
Interior
Condition of walls, ceilings, and floors. Signs of water staining, cracks, or movement. Window and door operation. Any signs of past or active water intrusion.
Specialty Inspections That Matter in Northern NJ
Several specialty inspections are particularly important for older NJ homes or specific site conditions. These are in addition to — not a replacement for — the standard home inspection.
Radon Testing
NJ has areas with elevated radon levels. Radon is a colorless, odorless gas that can accumulate in basements and lower levels. A separate radon test is inexpensive and strongly recommended.
Oil Tank Inspection / Scan
Many Northern NJ homes were historically heated by oil. Underground oil storage tanks (USTs) may still be present even if decommissioned. An undisclosed or leaking UST can be a significant liability. A tank sweep or scan is important for any older NJ home.
Sewer Line Scope
A camera inspection of the sewer line from house to street can identify tree root intrusion, collapsed sections, or deteriorated pipes — especially in older NJ homes. Sewer line replacement can cost thousands of dollars.
Mold Testing
If the inspector identifies areas of concern — particularly in basements, crawlspaces, or areas with past water intrusion — a mold test can clarify the presence and type of mold.
Lead Paint Testing
Homes built before 1978 may contain lead-based paint. While sellers are required to disclose known lead paint, a test can confirm whether it is present. Important in NJ where significant pre-1978 housing stock exists.
Chimney Inspection
A Level 2 chimney inspection (recommended when buying) examines the interior condition of flue liners, firebox, and chimney structure using a camera. Chimney issues can be expensive to repair.
Structural Engineering Evaluation
If a home inspector flags concerns about structural elements — foundation cracks, settling, beam or joist issues — a structural engineer's assessment may be warranted before proceeding.
Home Inspection FAQ
Is a home inspection required in NJ?
A home inspection is not legally required in New Jersey. However, skipping it is one of the most consequential decisions a buyer can make. Without an inspection, you have no way to identify hidden defects that could cost tens of thousands of dollars to repair after purchase.
Who selects and pays for the home inspector?
The buyer selects and pays for the home inspection. The inspector works for and reports to the buyer. Do not use an inspector recommended by the seller or listing agent — choose an independent NJ-licensed home inspector.
What can I do if the inspection reveals problems?
After the inspection, buyers typically have several options: negotiate with the seller to make repairs before closing, request a credit toward closing costs or purchase price to address issues, proceed with the purchase as-is if the issues are acceptable, or, in some circumstances, use the inspection findings to negotiate further or exit the transaction. Your real estate attorney can advise on options based on your contract.
Can I be present during the home inspection?
Yes — and buyers are strongly encouraged to attend. Being present allows you to see issues firsthand and ask questions. The inspector can explain the significance of findings in real time, which is more valuable than just reading the written report.
What does a home inspection not cover?
A standard home inspection is a visual inspection of accessible areas. It does not include invasive testing, opening walls, moving furniture, or testing underground systems (like septic tanks). That's why specialty inspections for radon, oil tanks, sewer lines, and other systems are recommended in addition to the standard inspection.
