A question I hear all the time is whether a NJ home inspector checks everything in a house. The answer is no. A home inspection is very detailed and covers all the major systems, but it does have limits. The New Jersey home inspection regulations make it clear what we are required to look at and what is outside the scope.
What inspectors do check
A standard home inspection in New Jersey is a visual, non-invasive inspection of what can be safely accessed. The regulations require us to inspect:
-
Structural components like the foundation, walls, ceilings, floors, roof framing, and attic
-
Roofing materials, flashing, skylights, chimneys, and gutters
-
The exterior including siding, windows, doors, decks, porches, garages, grading and drainage
-
Plumbing systems: supply piping, drains, fixtures, water heaters, and sump pumps
-
Electrical systems: service panels, breakers, wiring types where visible, outlets, and lights
-
Heating and cooling systems to see how they respond to normal controls
-
Interiors: doors, windows, stairs, walls, ceilings, floors, and handrails
-
Insulation and ventilation in attics and crawlspaces
-
Fireplaces and solid-fuel appliances where visible
Inspectors are also required to state in the report what was not inspected and the reason why. For example, if a crawlspace is blocked off or the roof is covered in snow, that has to be noted.
What inspectors are not required to check
The regulations also spell out what is not required. A home inspection is not a guarantee and it is not a code compliance inspection. Here are things that are outside the scope:
-
Hidden or concealed defects behind walls, floors, or ceilings
-
Predicting the life expectancy or future performance of systems and appliances
-
Checking building code compliance or permits
-
Moving furniture, stored items, or personal belongings to gain access
-
Operating shut-off valves or systems that are turned off or do not respond to normal controls
-
Testing for mold, asbestos, radon, lead paint, or other environmental hazards unless separately ordered
-
Inserting tools into electrical panels or dismantling mechanical equipment
-
Entering unsafe areas or areas without safe access
Systems not included in a standard inspection
Buyers are often surprised that some systems in a home are not covered under the NJ Home Inspection regulations. These include:
-
Lawn irrigation and sprinkler systems
-
Central vacuum systems
-
Humidifiers, dehumidifiers, and water softeners
-
Security systems, burglar alarms, intercoms, and central fire alarms
-
Pools, hot tubs, and spas
-
Septic systems and private wells
-
Underground storage tanks
-
Cosmetic items like paint, wallpaper, and carpeting
-
Outbuildings, barns, and sheds unless specifically agreed upon
-
Kitchen appliances beyond basic on/off testing
Inspectors may make a note if something looks obviously wrong with these systems, but they are not required to test or evaluate them. These areas are considered specialized and should be checked by contractors who service them.
Why this matters
When buyers ask if we check everything, what they really want is peace of mind. I always explain that no inspector can see through walls or guarantee nothing will go wrong after you move in. What we can do is reduce your risk by taking a long, careful look at the major systems and pointing out defects and safety issues.
This is also why many of the best NJ home inspectors offer or coordinate extra services like radon testing, mold inspections, termite inspections, and sewer line inspections. These areas are not part of the standard inspection but can reveal serious problems.
The takeaway
So do NJ home inspectors check everything in a house? No. We check everything that can be reasonably accessed and operated safely. The regulations require us to inspect all the major systems and to note what was not inspected. That means you get a detailed picture of the home, but not a guarantee that every hidden problem will be found.
The goal of a home inspection is not perfection. The goal is to give the buyer an honest, detailed report that lowers their risk and helps them make smart decisions.
