New-Construction Home Warranties Explained: What's Covered, What's Not

One of the genuine advantages of buying a brand-new home is that it comes with a written promise the seller of a resale home almost never offers: a builder warranty. If something the builder was responsible for fails within a defined window, they fix it. That's a real benefit, and it's worth understanding well — because the single document called a 'warranty' is actually three different promises, each covering different things and each expiring on a different clock.

Most buyers sign the warranty paperwork at closing, file it in a drawer, and never look at it again until a door won't latch or a seam cracks. By then the questions get urgent: Is this covered? Who do I call? How long do I have? This guide answers those before you need them. The goal isn't to make you wary of builders — in our experience they generally honor what they put in writing — it's to make you fluent in a document that's genuinely worth reading. We tour new-construction communities across Middle Tennessee constantly and represent buyers in them, and this is the honest, end-to-end version.

What is a new-construction home warranty?

A builder warranty is the builder's written commitment to repair or correct certain defects in your home for a set period after you close. It's a contract, not a courtesy — the terms are spelled out in a document you receive at or before closing, and those terms govern everything: what's covered, what isn't, how long coverage lasts, how you make a claim, and how disputes get resolved.

Two structural points are worth understanding up front. First, the warranty is often administered by a third-party warranty company rather than the builder directly — names like 2-10 Home Buyers Warranty or Professional Warranty Service Corporation are common nationally — which means coverage is backed by a defined program with its own claim process and standards, not just a handshake. Second, the warranty almost always defines defects against published 'tolerances,' measurable standards for things like how far a floor can be out of level or how wide a drywall crack can be before it counts. A crack you find alarming may sit inside the allowed tolerance; a crack you'd shrug at may exceed it. The document tells you which is which.

What is the 1-2-10 warranty structure?

The most common new-home warranty in the United States follows a '1-2-10' framework. The numbers refer to years, and each one covers a different category of the home — it's the single most useful thing to memorize, because it tells you at a glance how long you have to flag any given problem:

• •1 year — workmanship and materials. The broadest, most-used tier. It covers the finished, visible parts of the home: drywall, paint, trim, cabinets, countertops, flooring, doors, hardware, fixtures, and the general fit-and-finish of what the builder installed.
• •2 years — systems (sometimes called the 'distribution systems'). Covers the home's mechanical guts: plumbing, electrical, heating, ventilation, and air conditioning — the rough-in and distribution side of those systems, not necessarily the appliances themselves.
• •10 years — major structural. The longest and narrowest tier. Covers defects in the load-bearing structure — foundation, load-bearing walls, beams, girders, roof framing — that compromise the home's structural integrity.

Read those clocks carefully, because they stack from broad-and-short to narrow-and-long. The widest coverage expires first; the narrowest lasts longest. That design isn't accidental — finish problems tend to show up early, while a genuine structural defect can take years to reveal itself, so the categories most likely to surface quickly get the shortest windows and the rare, catastrophic ones get a decade. That said, '1-2-10' is the common shape, not a universal rule. Some builders offer their own terms; some pair a shorter in-house warranty with a separate structural program. Tennessee does not impose a single statutory new-home warranty the way a handful of states do, so the document your builder hands you — not a rule of thumb — is the authority. Always confirm the actual numbers and covered items in your specific warranty.

What does the one-year workmanship warranty cover?

This is the tier you'll use most, and it's why the first twelve months in a new home deserve your attention. It covers defects in the way the home was built and finished, measured against the warranty's tolerances. The year-one list tends to look like this:

• •Drywall cracks, nail pops, and seams that open beyond the allowed tolerance
• •Doors and windows that stick, won't latch, or were installed out of square
• •Cabinet and trim defects — misaligned doors, separating joints, finish flaws
• •Flooring problems such as lifting, gapping, or squeaks beyond tolerance
• •Paint coverage and touch-up issues from the original work
• •Grout and caulk failures, and minor plumbing or fixture adjustments
• •Hardware, fixtures, and finish items that weren't installed correctly

Year one is also when a new home does most of its 'settling.' Lumber dries, foundations cure, and the house moves slightly as everything finds its final position — which is exactly why hairline drywall cracks and a few nail pops are normal rather than alarming. Many builders schedule a deliberate end-of-year visit to address accumulated settling items in one pass. If yours doesn't, you should be the one to schedule it before the clock runs out.

What does the two-year systems warranty cover?

The systems tier covers the parts of the home you don't see: the plumbing, electrical, heating, and cooling distribution that runs behind the walls and under the floors. The covered scope is generally the builder's installation of these systems — leaks in supply or drain lines, wiring defects, ductwork problems, or an HVAC system that wasn't installed to perform as designed.

An important distinction lives inside this tier. The systems warranty typically covers the distribution — the pipes, wiring, and ducts the builder installed — while the equipment itself, your furnace, air handler, water heater, and major appliances, is usually covered by the manufacturer's own warranty, which runs on its own separate timeline and is claimed directly with that manufacturer. Two different warranties, two different phone numbers. Knowing which is which saves you from calling the builder about a problem the appliance maker handles, or vice versa.

What does the ten-year structural warranty cover?

The structural warranty is the longest, the narrowest, and the most misunderstood. It does not cover cosmetic cracks, settling, or finish problems that appear after year one. It covers 'major structural defects' — a phrase with a specific, demanding meaning, generally actual physical damage to designated load-bearing elements that makes the home unsafe, unsanitary, or unlivable. The load-bearing elements typically named are the foundation footings and systems, beams, girders, lintels, columns, load-bearing walls and partitions, and the roof framing and supporting structure. The test is high on purpose: a hairline crack in a basement slab almost never qualifies, but a foundation failure that compromises the structure does. Because the bar is structural integrity rather than appearance, ten-year claims are comparatively rare — which is also why the coverage can stretch that long.

The walkthrough: your first and best chance to flag problems

Before you close, the builder schedules a final walkthrough — sometimes called the new-home orientation or blue-tape walk. This is the single most valuable hour in the entire warranty process, because it's your chance to document every visible item while the builder is standing right there and the home is empty, clean, and fully lit. Items caught here usually get fixed before or shortly after closing, without the friction of a formal claim later. Treat it as work, not a celebration. Bring a roll of painter's tape and mark anything that needs attention — a scuffed wall, a chip in a counter, a door that drags, a missing switch plate, a window that won't lock — and photograph every flagged item.

1. Walk the exterior first — grading, gutters, exterior paint, the driveway and walkways, and any visible flashing or trim gaps.
2. Test every operating part — faucets, toilets, the disposal, the dishwasher, the range, exhaust fans, the garage door, and the HVAC in both modes.
3. Open and close every door and window, checking latches, locks, and smooth operation.
4. Inspect finishes room by room in good light — walls, ceilings, floors, cabinets, counters, and trim.
5. Confirm what you were promised — the right fixtures, the selected finishes, included appliances, and any options you paid for.
6. Photograph and list everything, then get the builder to acknowledge the list in writing before you sign.

The punch list: getting walkthrough items fixed

The written list of items from your walkthrough is the 'punch list' — the agreed record of what the builder will correct. The discipline that makes it work is simple: everything in writing, with photos, acknowledged by the builder. A verbal 'we'll take care of that' is not a punch-list item; a signed list is. After closing, the builder works through it on their schedule — some items are same-day, some (a backordered cabinet door, a special-order fixture) take longer. Keep your own copy and check items off as they're genuinely completed, not as they're promised. If an item lingers, your dated, photographed record is exactly what keeps the conversation factual and moving.

How to actually use the warranty period

A warranty is only as good as your use of it, and the most common way buyers lose coverage isn't a denied claim — it's a missed deadline. The single most useful habit is to put the expiration dates on your calendar the week you close — the one-year date, the two-year date, and the ten-year date — and treat the weeks before each one as a deliberate inspection window. The working routine looks like this:

1. Calendar all three expiration dates the week you move in, with a reminder set 30 to 45 days before each.
2. Live with the home and keep a running list — a note on your phone — of anything that isn't right, no matter how small, as you notice it.
3. Submit claims in writing through the channel the warranty specifies, with photos, dates, and a clear description. Verbal requests are easy to lose.
4. Keep records of every claim, response, and repair — the request, the builder's reply, and confirmation the fix was completed.
5. Schedule a deliberate sweep before the one-year date especially, since the broadest coverage expires first and most settling has finished by then.

The eleven-month inspection is the habit worth borrowing above all. Roughly a month before your one-year workmanship coverage ends, walk the home — or have an independent inspector walk it, which is a reasonable move even on a brand-new house, since a third set of trained eyes catches installation issues a homeowner wouldn't — specifically hunting for anything that's drifted out of tolerance over the first year. Submit that list before the deadline. After the walkthrough itself, it's the highest-leverage hour you'll spend on the warranty.

What is NOT covered

This is where most warranty disappointment comes from — not a builder refusing a valid claim, but a buyer assuming something was covered that the document plainly excludes. Coverage is for defects in the builder's work, within the stated tolerances and timeframes; it is not a maintenance contract or an insurance policy. The common exclusions:

• •Normal wear and tear, and routine maintenance you're responsible for — caulking, filter changes, re-sealing, and the like
• •Damage from the homeowner's own actions, neglect, or alterations made after closing
• •Cosmetic settling and minor cracking that falls within the allowed tolerances
• •Anything covered instead by a separate manufacturer's warranty — appliances, the furnace, the water heater, and similar equipment
• •Damage from weather events, floods, fire, or other casualty losses, which are the domain of your homeowner's insurance, not the builder
• •Landscaping, sod, and exterior plantings, which typically have very short coverage windows or none at all
• •Problems caused by failing to perform the maintenance the warranty requires you to perform
• •Consequential or secondary damage in many programs — for example, the warranty may repair a leaking pipe but exclude the resulting damage to your belongings

Two of these trip people up most often. The first is the appliance line: when the dishwasher fails in month eighteen, the instinct is to call the builder, but the fix runs through the manufacturer on its own schedule. The second is insurance: a builder warranty and a homeowner's insurance policy cover almost entirely different things, and you genuinely need both. The warranty handles defects in how the home was built; insurance handles fire, storms, theft, liability, and the unexpected. Neither one substitutes for the other.

How disputes get handled

Most warranty items never become disputes — they get fixed. But it's worth knowing the structure before you need it. Many new-home warranties, especially those backed by a third-party program, specify a defined claims procedure and, for disagreements, binding arbitration or mediation rather than the court system. That's a meaningful contract term you agree to at closing, and one more reason to read the document rather than discover it during a disagreement. When a claim is genuinely contested, the program usually turns to its published tolerances and an independent assessment to decide whether the item qualifies. Your best position in any of this is the boring one: a clear, dated, photographed paper trail from the walkthrough forward. Documentation isn't adversarial — it's just what keeps everyone honest and the facts straight.

How we help on the warranty side

Because we tour new-construction communities across Middle Tennessee constantly, the warranty is part of how we represent buyers from the first model visit onward. We'll read the builder's specific warranty with you before you're under contract — so the clocks, the tolerances, and the exclusions are clear before they matter rather than after — come to the walkthrough to help you build a thorough punch list, and stay reachable after closing, when the eleven-month inspection and the year-one deadline are easy to forget. None of that changes the warranty itself; the builder's promise is the builder's promise. What it changes is whether you use it well. We put the relationship in writing, too: every buyer agreement we sign includes a 24-hour kickout, so written notice releases you within a day if it isn't working.

Frequently asked questions

Is a builder warranty the same as a home warranty I'd buy on a resale home?

No. A builder warranty covers defects in how your new home was constructed, on the tiered clock above, and it comes with the home at no separate charge. A home warranty service contract — the kind sometimes bought on a resale — is a paid subscription that covers repair or replacement of aging systems and appliances regardless of who built them. They solve different problems, and the builder warranty is the one that comes standard with new construction.

Do I still need homeowner's insurance if my new home has a warranty?

Yes, absolutely, and your lender will require it. The warranty and the insurance policy cover almost entirely different risks. The warranty handles construction defects; insurance handles fire, storms, water damage from a covered event, theft, and liability. A warranty is not insurance and never replaces it.

Should I hire my own inspector for a brand-new home?

It's optional but rarely a bad idea. A new home is still built by people, and an independent inspector brings trained eyes to the walkthrough and again before the one-year deadline. Many buyers do this on both occasions. It's a modest expense against a major purchase, and it tends to surface installation items a homeowner wouldn't catch.

What if the builder is slow to address a covered item?

Keep it in writing and keep it factual. Submit the claim through the channel the warranty specifies, with photos and dates, and keep a record of every response. Most items resolve once they're documented and tracked. If one genuinely stalls, your dated paper trail is exactly what the warranty program's claims procedure relies on — which is the strongest reason to start that trail at the walkthrough.
