In a competitive North Jersey market, one question comes up on nearly every buyer call: do I really need a home inspection, and can I waive it to make my offer stronger? The short answer is that the home inspection contingency is the single most important protection a buyer has after an offer is accepted, and while you can waive it, you should understand exactly what you are giving up first.
This guide walks through how the contingency works in New Jersey, what a typical inspection covers, the NJ-specific add-ons most buyers should not skip, how to negotiate repairs or credits, and the deal-breaker findings that justify walking away with your earnest money in hand.
What is the home inspection contingency?
The home inspection contingency is a clause in the New Jersey Contract of Sale that gives the buyer a defined window, typically 10 to 14 calendar days, to have the property professionally inspected. During that window the buyer can accept the home as-is, negotiate for repairs or credits, or terminate the contract and get the full earnest money deposit back. If the buyer does not act within the window, the contingency expires and the buyer is generally locked in.
It is one of three major contingencies in a standard NJ contract, alongside the mortgage contingency and the appraisal contingency. Of the three, the inspection contingency gives you the earliest look at whether the home actually matches the story the listing told.
NJ attorney review comes first
New Jersey is one of a small number of states with a mandatory attorney review period. After both parties sign the Contract of Sale, a 3-business-day attorney review clock starts. During that window, either side's attorney can propose changes, disapprove the contract, or terminate it entirely. The inspection contingency window does not begin until attorney review closes.
In practice this means the earliest a buyer schedules an inspection is the day attorney review ends. For a deeper look at how attorney review interacts with the rest of the contract, see our companion guide on buying your first home in NJ.
The standard inspection timeline
Here is what a normal 14-day inspection contingency looks like on a North Jersey deal:
- Day 0: Attorney review closes. Inspection contingency clock starts.
- Days 1 to 3: Schedule and complete the general home inspection plus any add-ons (radon, oil tank sweep, termite, sewer scope).
- Days 4 to 7: Inspection reports come in. Buyer reviews with agent and attorney, decides which items to raise.
- Days 8 to 12: Attorney sends the inspection response letter listing requested repairs or credits.
- Days 13 to 14: Sellers respond, negotiate, and either agree, counter, or refuse. Buyer decides to proceed, accept a compromise, or terminate.
If more time is needed, extensions are common when both parties agree in writing. Most attorneys will grant a short extension if a specialist inspection was delayed or an estimate is still pending.

What a NJ home inspection covers
A licensed New Jersey home inspector spends roughly two to four hours walking the property and produces a written report, usually with photos, within 24 to 48 hours. The general inspection covers:
- Foundation and structural components
- Roof surface, flashing, gutters, and attic
- Electrical panel, wiring, and outlets
- Plumbing supply, drain flow, water pressure, and water heater
- HVAC systems (furnace, boiler, central air, mini-splits)
- Windows and doors, including seals and operation
- Insulation and ventilation
- Basement condition, water intrusion, and visible cracks
- Kitchen fixtures and built-in appliances
- Bathrooms, fixtures, and visible plumbing
- Chimney and fireplace (if present)
- Deck, porch, and patio structure
- Exterior siding, trim, and drainage grading
- Garage door, opener, and structure
What it does not cover: anything behind walls, buried oil tanks, radon, termites, wells, septic, lead paint, mold testing, or sewer laterals. Each of those needs a separate specialist.
NJ-specific inspections most buyers should add
These add-ons are where local knowledge pays off. Skipping them is where post-closing surprises come from.
Buried oil tank sweep
Any North Jersey home built before roughly 1990 could have a buried oil tank in the yard, whether the seller knows about it or not. A leaking tank can trigger $10,000 to $100,000+ in soil remediation and is a nightmare to unwind after closing. A ground-scan sweep costs $150 to $500. See our full NJ oil tank sweep buyer guide for what to do if a tank is found.
Radon testing
Radon is elevated across much of northern and western NJ. A 48-hour canister test runs $150 to $300. If results exceed 4.0 pCi/L, a mitigation system costs $1,200 to $2,500 and is very commonly negotiated onto the seller.
Termite and wood-destroying insect inspection
Most NJ lenders require a WDI inspection, and FHA and VA loans always do. It costs $100 to $300 and catches active termite, carpenter ant, and powder post beetle activity.
Well and septic testing
For rural properties in Sussex, Warren, western Morris, and parts of Hunterdon counties, well water quality and flow tests plus a septic dye or camera test are essential. Budget $400 to $900 combined.
Lead paint
Any home built before 1978 may have lead-based paint. Testing is inexpensive and matters most if young children will live there.
Sewer scope
A camera is pushed through the main sewer line to look for cracks, root intrusion, and clay pipe collapse. For any home built before 1980, or one with mature trees near the line, a $250 to $500 scope is one of the smartest add-ons on the list. A full lateral replacement runs $5,000 to $25,000.
The 4 options after the inspection
Once reports are in and reviewed with your agent and attorney, you have four paths forward:
- Accept as-is. The property checks out or issues are minor. Move to mortgage commitment.
- Request repairs before closing. Ask the seller to fix specific items with proof of licensed work.
- Request a credit or price reduction. Often preferred by both sides. You control who does the work and to what standard.
- Terminate the contract. Walk away in writing during the contingency window and receive your earnest money deposit back in full.
How to negotiate repairs in NJ
The way you frame the ask matters as much as the ask itself. Sellers reliably fix or credit for:
- Safety hazards (double-tapped breakers, ungrounded outlets near water, missing GFCIs)
- Structural issues (foundation cracks, roof leaks, rotted framing)
- Active water intrusion
- Failed or end-of-life mechanical systems (dead furnace, leaking water heater)
- Code-violating work uncovered during inspection
Sellers reliably push back on:
- Cosmetic items (paint chips, worn carpet, dated finishes)
- Aging but functional systems (a 12-year-old water heater still working)
- Deferred maintenance the buyer could have seen at showings
- Long wish-lists that look like buyer's remorse
Prioritize a short, credible list of safety and structural items. In our experience, a focused three-item ask closes; a 22-item shopping list gets refused.
Real numbers: typical repair credits
| Issue Found | Typical Credit Range |
|---|---|
| Roof, 5 to 10 years of life left | $2,000 to $5,000 |
| Foundation crack, non-structural repair | $3,000 to $10,000 |
| Water heater, end of life | $1,000 to $2,000 |
| Electrical panel update (100A to 200A) | $2,000 to $4,000 |
| HVAC failure or replacement | $5,000 to $12,000 |
| Radon mitigation system | $1,200 to $2,500 |
| Sewer line repair | $5,000 to $25,000 |
Estimates based on typical 2026 North Jersey transactions. Actual outcomes depend on contract dynamics, market conditions, and the specific defect.
When to walk away
Some findings should end the conversation, regardless of how much you love the house:
- Extensive foundation problems with structural engineer estimates north of $20,000
- Buried oil tank with confirmed soil contamination and no seller willingness to remediate
- Roof at complete end of life with widespread deck damage
- Extensive mold, particularly in a finished basement or behind walls
- Illegal additions or finished spaces built without permits
- Environmental hazards (asbestos, contaminated well, high radon paired with refusal to mitigate)
Walking away is not failure. It is exactly what the contingency exists for, and your deposit comes back.
Should you waive the inspection?
In hot 2026 pockets of North Jersey, buyers sometimes waive the inspection to compete. It is legal, and in a multiple-offer situation it can be the difference between winning and losing the house. It is also the single fastest way to inherit an expensive problem.
Two safer middle-ground moves:
- Pre-offer inspection. Pay for a general inspection before you submit an offer, when the property is briefly on the market. You know what you are buying and you can offer with confidence.
- Informational-only inspection. Keep the inspection in your contract but waive the right to negotiate or cancel based on findings. Sellers see it as almost as strong as a full waiver, and you still get a full report to plan repairs post-closing.
Whatever you decide, decide with a licensed agent and a NJ real estate attorney at the table. Waiving without understanding the risk is the story we hear most often after closing.
FAQ
How long is the home inspection contingency in NJ?
Most North Jersey contracts allow 10 to 14 calendar days after attorney review ends. The window covers both the physical inspection and time to negotiate repairs, credits, or termination. Extensions are common if both parties agree in writing.
Who pays for the home inspection in NJ?
The buyer pays the inspector directly, typically the day of the inspection. Sellers do not pay for the buyer's inspection, though some sellers order a pre-listing inspection at their own cost to smooth the sale.
What does a NJ home inspection cost?
A standard general home inspection runs $400 to $800 depending on square footage and age. Add-ons: radon test $150 to $300, WDI or termite inspection $100 to $300, oil tank sweep $150 to $500, sewer scope $250 to $500.
Can I waive the inspection contingency in NJ?
Yes, and it has become common in competitive markets. It is risky because you lose the right to walk away or renegotiate if defects are found. Safer alternatives include a pre-offer inspection or an informational-only inspection with no cancellation right.
What if the seller refuses to make repairs?
Three choices: accept the home as-is, counter with a smaller ask (often a closing credit rather than repairs), or terminate the contract and receive the earnest money back. Sellers rarely refuse safety-related items but frequently push back on cosmetic requests.
Can I get my earnest money back after inspection?
Yes. If you terminate in writing during the inspection contingency window based on inspection findings, your deposit is returned in full. Your attorney handles the termination notice and release of funds.
Do I need a separate oil tank sweep?
For any NJ home built before 1990, yes. Standard inspections do not scan for buried tanks. A separate ground-scan sweep detects abandoned underground storage tanks, which can carry $10,000 to $100,000+ in remediation liability if leaking.
Is a termite inspection required in NJ?
Most NJ lenders require a wood-destroying insect inspection, and FHA and VA loans always do. Even when not required, it is smart because termites and carpenter ants are widespread across the state.
What is radon testing and do I need it?
Radon is a naturally occurring radioactive gas. NJ has elevated levels in many counties, particularly the northern and western regions. A 48-hour test costs $150 to $300. If levels exceed 4.0 pCi/L, a $1,200 to $2,500 mitigation system is commonly negotiated onto the seller.
Should I do a sewer scope inspection?
Strongly recommended for any home built before 1980, and essential when mature trees sit near the sewer line. A $300 camera scope is cheap insurance against a $5,000 to $25,000 lateral replacement.
The bottom line
The home inspection contingency is not a formality. It is the buyer's leverage moment, the point at which you learn what you are actually buying and decide what price and condition still makes sense. Used well, it saves money, prevents nasty surprises, and gives you the option to walk without penalty. Waived carelessly, it becomes the reason first-time buyers post regretful stories online six months after closing.
The buyers who fare best in a hot NJ market are not the ones who waive protections fastest. They are the ones who understand each protection well enough to know when it is worth keeping.
