Do I Need a Home Inspection on a New Construction House on Long Island?
By Moataz “Mo” Elshamy, Licensed Real Estate Associate Broker, Integrity Core Realty · Last updated November 3, 2026
Brand new house. New roof, new siding, new everything. Listed at $1,649,000 in East Meadow.
My buyers had been searching for a year, with three agents before me. They loved it. And at the first showing, I noticed a faint yellow stain on the ceiling that almost nobody would look at twice.
That stain turned out to be a brand-new roof that was installed wrong. Here’s why a new construction house on Long Island still needs a real inspection, what “new” actually protects you from, and what to do when the problem shows up after you’ve signed.
Mo’s quick answer: Yes. Get an independent home inspection on new construction, and do it before you sign the contract. The town’s inspections and the Certificate of Occupancy confirm the house meets minimum code. They don’t confirm it was built well. New York’s new home warranty law gives you rights after closing, but a warranty claim is a fight you have later, while you live with the problem. The inspection is how you find it while you still have leverage.
Doesn’t the Certificate of Occupancy Mean the House Is Fine?
No. This is the most common assumption I hear from buyers on new builds, and it’s the most expensive one.
A Certificate of Occupancy means the building department signed off that the house can legally be lived in. The town’s inspectors check specific stages against code, and code is the legal minimum. Their job isn’t to tell you whether the roof was flashed carefully, whether the grading sends water toward your foundation, or whether a bathroom fan vents into the attic instead of outside.
Your own inspector works for you. Here’s how the people involved in a new build actually differ:
| Who looks at the house | Who they work for | What they’re checking | What they don’t promise you |
|---|---|---|---|
| Town building inspector | The municipality | Code compliance at set stages, leading to the CO | Workmanship, quality, or that nothing was missed between visits |
| Builder or investor | Themselves | Finishing the house and selling it | An objective opinion of their own work |
| Lender’s appraiser | The lender | Value, plus obvious condition issues that affect the loan | A systems or workmanship inspection |
| Your home inspector | You | Roof, structure, water, mechanicals, electrical, plumbing, grading, attic | What’s hidden behind finished walls (which is why pre-drywall inspections exist) |
What Inspections Find on Brand-New Long Island Houses
On an older home, the problems announce themselves: worn shingles, old wiring, a tired boiler. On a new build, everything looks perfect, so the problems are in how things were put together. The ones that matter most:
- Roof and flashing: missing or poorly installed flashing around chimneys, dormers, skylights and roof-to-wall joints. New roofs can leak from day one.
- Water and grading: soil sloping toward the house, short downspouts, window and door flashing done wrong.
- Attic and ventilation: bath fans or dryer vents ending in the attic, missing insulation, poor attic ventilation.
- Mechanicals: HVAC, plumbing and electrical installed fast by different subcontractors, with no one checking each other’s work.
- Unfinished details: GFCI protection, railings, missing caulking, items on the town’s list that were signed off but not completed the way you’d expect.
A lot of Long Island new construction is built by small builders and investors who tear down an older house and build one or two new ones. Some are excellent. Some move fast to sell fast. You can’t tell which from the listing photos, and you shouldn’t try to.
From My Experience: The $1.6M New House With a Leaking Roof
A faint stain, a signed contract, and a lender’s letter
My buyers, a couple I’ll call Dan and Lisa, found a fully new-built house in East Meadow: about 3,000 square feet, listed at $1,649,000, built by an investor. We negotiated it to $1,600,000.
At the showing I noticed a faint yellow stain on a ceiling. The buyers chose an inspector a family member had used before. I can’t choose a buyer’s inspector for them, and I won’t pretend I liked this one. I pointed the stain out, and he brushed it off. The report came back fine, and the contract was signed.
I wasn’t comfortable. I told my buyers what I’d seen, and they insisted on a second inspection. That inspector traced the stain to the brand-new roof. It had been installed wrong.
Now we were in contract, and the other side’s answer was basically, “There’s nothing wrong.” It turned into a real standoff, to the point where we thought the deal might fall apart. I worked with the listing agent and the buyers’ attorney to treat it as a defect. Then I went to the lender and got a statement that it would not approve the loan on a house with a leaking roof.
That letter ended the debate. The investor replaced the entire roof at his own cost in two days. The roofer gave a written certification and a one-year warranty on the work. I got the inspector to come back and check the new roof at no extra charge, and he gave it a thumbs up.
We closed on time. Dan and Lisa moved into a $1.6M house with a new roof that was actually done right, instead of finding the leak themselves the first winter.
Two lessons from that deal. First, pick the inspector for how thorough they are, not because someone in the family knows them. Second, in New York the inspection usually happens before the contract is signed. Once it’s signed, your leverage shrinks a lot. We got that roof fixed after signing, but it took a fight and a lender’s letter. Most buyers never get that far.
What Does New York’s New Home Warranty Actually Cover?
New York has a new home warranty law, Article 36-B of the General Business Law, often called the housing merchant implied warranty. When it applies, it’s built into the contract for the sale of a new home and survives the closing.
| Period (from the warranty date) | What the law says the home will be free from |
|---|---|
| 1 year | Defects from failure to build in a skillful manner |
| 2 years | Defects in how the plumbing, electrical, heating, cooling and ventilation systems were installed |
| 6 years | Material defects |
Before you lean on it, know its limits:
- The builder can replace it. The law allows a builder to exclude or modify the implied warranty by offering a written limited warranty that meets the statute’s requirements. Read what you’re actually getting.
- It doesn’t cover every new house. For example, it doesn’t apply to a house built on land the buyer already owned. Whether it applies to your purchase is a question for your attorney.
- There are notice rules and deadlines. The builder must get written notice of a claim and a chance to inspect and repair before you can sue.
- A warranty is only as good as the builder behind it. A small investor-builder may be hard to reach or gone by the time you need them.
The warranty is your backup plan. The inspection is your plan.
“It’s brand new and it passed the town’s inspections. An inspection is a waste of money.”
The town checks minimum code at set stages. A new roof can pass and still leak. One inspection costs a small fraction of what one roof does.
When Should You Inspect a New Build?
Before the walls close
If you’re buying before the house is finished, a pre-drywall inspection lets an inspector see framing, wiring, plumbing and insulation while they’re still visible. Ask the builder in writing for access.
Before you sign
On a finished house, the full inspection should happen before the contract is signed, like any Long Island purchase. This is where your leverage is.
Before year one ends
Many buyers schedule another inspection shortly before the one-year mark, so workmanship issues are reported in writing while the shortest warranty period is still open.
What If the Inspection Finds a Problem on a New House?
On a new build, the conversation is different than on a 70-year-old house. You’re not asking the builder to update something old. You’re asking them to finish their own work correctly. That usually means a repair, not a credit.
- Ask for the repair done right, before closing, with the scope agreed in writing through the attorneys.
- Get paperwork on the fix: a written certification, warranty, and permit sign-off if the work requires one.
- Have your inspector recheck it before closing. Don’t take “it’s done” on faith.
- Know what your lender will require. A lender may refuse to fund until a condition like a leak is fixed. That can work in your favor, as it did for Dan and Lisa.
- Be ready to walk if the builder won’t fix a serious defect. A beautiful house with a bad roof is still a house with a bad roof.
Your attorney handles the contract terms. My job is to read the house, read the other side, and make sure the problem gets solved without losing the deal you worked hard for. If you’re still deciding whether to skip an inspection to compete, read my take on waiving the home inspection on Long Island first.
Common Mistakes Buyers Make on New Construction
- Treating the CO as a quality certificate.
- Using the builder’s recommended inspector, or a friend of the family, instead of the most thorough one you can find.
- Ignoring small signs like a faint stain or a damp smell because “it’s new.”
- Signing the contract first and inspecting later.
- Not reading whether the builder’s contract replaces the state’s implied warranty with a limited one.
- Accepting a repair without written proof and a recheck.
Frequently Asked Questions
Do I need a home inspection on a new construction house?
Yes. Town inspections and the Certificate of Occupancy confirm minimum code compliance, not workmanship. An independent inspector works for you and checks how the house was actually built.
Is a Certificate of Occupancy the same as a home inspection?
No. The CO means the building department approved the house for occupancy. It isn’t a review of quality, and it doesn’t mean nothing was missed.
When should I inspect a new build on Long Island?
On a finished house, before you sign the contract. If the house is still being built, add a pre-drywall inspection, and consider another inspection before the first year ends.
Does New York have a warranty on new homes?
Yes. Article 36-B of the General Business Law provides an implied warranty with one-, two- and six-year periods for different types of defects. A builder can replace it with a qualifying limited warranty, so have your attorney review what your contract provides.
Can I still get a problem fixed after the contract is signed?
Sometimes, but your leverage is much weaker. It depends on the contract, the defect, the lender and how the other side responds. Your attorney should advise you on your rights.
Will my lender approve a loan on a house with a leaking roof?
It may not. In my buyers’ case, the lender stated it would not approve the loan with a leaking roof, which is what got the roof replaced. Ask your lender early about any condition issue.
Should I ask for a repair or a credit on a new house?
Usually a repair, done right and documented, since the builder is fixing its own work. A credit can make sense in some cases, but your lender may limit credits, so check with them.
Can I use the builder’s inspector?
You can, but you shouldn’t rely on it. Hire an inspector who works only for you and has experience with new construction.
Mo’s Bottom Line
New doesn’t mean done right. It means the problems are newer and better hidden. Inspect before you sign, pay attention to the small things, and get every fix in writing. Dan and Lisa searched for a year. A faint stain almost cost them the house, or worse, their first winter in it.
Buying New Construction on Long Island?
If you’re serious about buying, tell me what you’re looking at. I’ll walk the house with you and tell you what I see, even the part you don’t want to hear. And if the honest answer is to walk away, I’ll tell you that too.
