The 11-Month Builder Warranty Walkthrough: A Checklist Before Your First Year Ends

There is a date sitting quietly on your calendar that most new-construction owners never mark: the one-year anniversary of your closing. For the first eleven or twelve months in a brand-new home, you are usually thrilled — the paint is fresh, nothing is broken yet, and the last thing on your mind is drafting a punch list. Then the anniversary passes, a hairline crack you had been ignoring widens, and you learn the hard way that the window to make your builder fix it for free has already closed.

That is the whole reason the month-11 walkthrough exists. Most new-home warranties follow a "1-2-10" structure: one year for workmanship and materials, two years for the mechanical systems, and ten years for major structural components. The one-year workmanship coverage is the shortest and the most valuable for the small, correctable defects that new houses accumulate — and it runs out fast. We treat the month-11 inspection the same way we treat a closing deadline: it is a hard date, and missing it costs real money. In Sumner County and across Middle Tennessee, where homes are going up quickly to keep pace with demand, running this walkthrough on time is one of the highest-return hours you will spend on your house all year.

Why Month 11 Is the Most Important Date on Your New-Home Calendar

Understanding the timing means understanding what happens when the clock runs out. The one-year workmanship warranty covers "fit and finish" — the cosmetic and finish-level work that shows defects only after the house has lived through a full cycle of seasons. Once your one-year anniversary passes, most builders are no longer contractually obligated to correct those workmanship defects at their expense. The house does not stop settling on that date; your leverage does.

The month-11 inspection is timed deliberately — roughly 10 to 11 months after move-in — so that defects are documented and submitted while the warranty is still live. That one-month buffer matters. It gives your builder time to schedule and complete repairs before the deadline, and it gives you time to escalate if the first response is slow. Wait until month 12 and you are negotiating from behind. Run the walkthrough at month 11 and you are negotiating with the warranty on your side.

This is exactly the kind of decision where we wear the investor's hat, even for clients buying a primary residence. A missed warranty window is not a minor inconvenience — it can quietly move thousands of dollars from your pocket to your builder's. One correctable defect caught on time is often the difference between a free repair and a five-figure out-of-pocket fix a few years down the road.

Understanding Your Warranty: The 1-2-10 Structure

Before you walk the house, read your actual warranty document. Most new homes come with a version of the 1-2-10 structure:

• •One year — workmanship and materials ("fit and finish"): drywall, paint, interior trim, cabinets, countertops, tile, interior doors, and similar finish items.
• •Two years — mechanical systems: plumbing, electrical, and HVAC.
• •Ten years — major structural components: foundation, load-bearing walls, and roof framing.

The one-year workmanship portion is the one under a countdown. On a typical 2-10 structure, that "fit and finish" coverage extends to defects in cabinets, countertops, door panels, exterior siding, hardwood floors, ceramic tile, drywall, interior trim, paint, and fireplaces — and it runs one year from the closing or coverage date. Those are precisely the items your month-11 walkthrough should hunt for, because after the anniversary they fall out of the warranty first.

A word of caution on the mechanical two-year window: it is longer, but a hot or cold room caused by an airflow imbalance is easiest to prove and cheapest to fix while everything is still new and the builder's subcontractors are still on call. Do not assume the two-year systems coverage means you can ignore HVAC now. Flag it during the workmanship walkthrough anyway.

New Isn't Perfect: Why Even Brand-New Middle Tennessee Builds Have Punch-List Items

There is a persistent myth that a newly built home does not need an inspection because it is new. The data says otherwise. Per National Association of Realtors reporting, 65% of homebuyers who inspected their newly built homes found issues, and 24% reported that their home did not pass the first inspection. New construction is built by human crews on a schedule, and defects are routine — not a sign you bought a bad house.

The defects a month-11 inspection targets are predictable: drywall cracks and nail pops, roof leaks, HVAC imbalances, insulation gaps, and plumbing drips. These stem from design flaws, substandard materials, or poor workmanship — not from owner neglect or normal wear. That distinction matters, because the warranty covers defects, not the ordinary consequences of living in the house.

Middle Tennessee adds its own reasons to look closely. Our region's expansive clay soils and freeze-thaw cycles put real stress on a foundation and its surrounding grade during that first year. Soil that swells with moisture and shrinks in dry spells is a classic driver of settling cracks and drainage problems — which is why grading and foundation-adjacent items deserve extra scrutiny here compared with a drier, more stable climate.

Should You Pay for an Independent Month-11 Inspection?

You can walk the house yourself with the checklist below, and you should. But we consistently recommend hiring an independent, licensed inspector for the month-11 visit — someone who works for you, not for the builder. A professional will get on the roof, into the attic and crawlspace, and behind the systems you cannot safely evaluate on your own, and they will produce a written report that carries weight in a warranty claim.

The cost is modest relative to what it protects. An 11-month builder-warranty inspection typically runs about $250 to $600, rising to roughly $650 to $1,000 in higher-cost markets. Many inspectors also offer a discounted package when the month-11 visit is bundled with the pre-drywall and final new-construction inspections — so if you are early in the process, ask about booking all three up front.

Here is the honest math. Set that $250 to $600 against a single warrantable HVAC imbalance, a drainage correction, or a run of drywall repairs you would otherwise pay for yourself once coverage lapses. Against the NAR reality that 65% of inspected new homes turn up issues, the inspection is not really an expense — it is cheap insurance on a purchase that likely represents the largest single line item on your family's balance sheet. This is the kind of small, disciplined edge that compounds: catch the fixable things while they are free, every year, on every property.

The Room-by-Room Walkthrough Checklist

Whether you hire an inspector or start on your own, work the house in a consistent order so nothing gets skipped. Bring a phone for photos, a flashlight, a tape measure, and your warranty document. Below is the sequence we walk with clients.

Exterior, Grading, and Drainage

Start outside, because grading and drainage problems cause the most expensive downstream damage and are the easiest to overlook. There is an objective standard to check against. IRC Section R401.3 (Drainage) requires lots to be graded so surface water drains away from foundation walls, with a fall of not fewer than 6 inches within the first 10 feet. Impervious surfaces — driveways, patios, sidewalks — within 10 feet of the foundation must slope not less than 2 percent away from the building. This language has been consistent across the 2012 through 2024 editions of the IRC, so it is not a moving target.

• •Walk the perimeter after a hard rain and look for water pooling against the foundation or in the yard.
• •Check that the ground falls away from the house — roughly six inches of drop across the first ten feet.
• •Confirm the driveway, patio, and walkways slope away from the foundation, not toward it.
• •Inspect siding, brick, and exterior trim for gaps, cracks, or caulk failures.
• •Look at gutters and downspouts: are they discharging well away from the foundation, or dumping right beside it?
• •Note any settling cracks in concrete flatwork, and photograph them with a tape measure for scale.

Interior: Drywall Cracks, Nail Pops, and What Actually Counts as a Defect

Some cracking in the first year is normal as lumber dries and the house settles. The question is where the line sits between "normal settling" and a warrantable defect — and there is a published answer. NAHB's Residential Construction Performance Guidelines set the measurable tolerances that builders and inspectors use to judge these claims. As a general benchmark, stress cracks in drywall should not exceed roughly 1/16 inch in width; builders typically repair cracks over 1/8 inch wide, and they usually repair nail pops and blisters one time only — often near the end of the first year, which is another reason to consolidate everything into a single month-11 submission.

• •Scan every wall and ceiling in raking light (a flashlight held nearly parallel to the surface) to reveal cracks and nail pops you would otherwise miss.
• •Measure crack widths. Note anything approaching or exceeding 1/8 inch.
• •Count and photograph nail pops and drywall blisters, room by room.
• •Check corners, seams above doorways, and the drywall around windows — common settling points.
• •Look for tape lines, sanding marks, and paint touch-ups that were done poorly.

Because nail pops are often a one-time repair, timing the fix for late in the first year is smart: the house has done most of its early settling by then, so the repair is more likely to stick.

Doors, Windows, Cabinets, and Countertops

Fit-and-finish items are squarely inside the one-year workmanship coverage, so this is where a careful walkthrough pays off directly.

• •Open and close every interior and exterior door. Check for sticking, dragging on the floor, gaps at the top or latch side, and doors that swing open or shut on their own (a sign the frame is out of plumb).
• •Operate every window — locks, cranks, sashes — and look for drafts, condensation between panes, and failed weatherstripping.
• •Open every cabinet and drawer. Check for misaligned doors, uneven gaps, loose hinges, and drawers that do not close flush.
• •Inspect countertop seams, edges, and the caulk line at the backsplash and sink.
• •Check caulking throughout — tubs, showers, sinks, countertops, and exterior penetrations — for gaps and shrinkage.

HVAC Balancing and Hot/Cold Rooms: The Two-Degree Test

If one bedroom is always stuffy and another is always chilly, that is not something to just live with — it is an airflow-balancing issue worth flagging before your systems warranty year is behind you. A two-degree temperature variation between rooms signals unequal air distribution. Many newer homes lack balancing dampers, and hot or cold rooms are corrected by adjusting the supply-duct dampers — a fixable problem, not a permanent quirk of the house.

• •With the system running, use a simple thermometer to compare temperatures room to room. Differences of about two degrees or more flag a balancing problem.
• •Check that every supply register pushes air and every return pulls it.
• •Note rooms that are consistently hot or cold and document the pattern over a few days.
• •Ask whether your ductwork has balancing dampers that can be adjusted.

Plumbing, Roof, Attic, and Garage

These are the areas where an independent inspector earns their fee, because much of it requires getting into places you should not go alone.

• •Plumbing: run every faucet, flush every toilet, and check under sinks and around water heaters for drips or staining. Look for slow drains and low pressure.
• •Roof and flashing: from the ground or, for a pro, on the roof, check for lifted shingles and failed flashing around penetrations; scan ceilings and the attic for any signs of a leak.
• •Attic: look for insulation gaps and uneven coverage, proper ventilation, and any daylight or water staining at the roof deck.
• •Garage: test the door and safety reverse, check the firewall and self-closing door to the house, and look for cracks in the slab.

How to Submit Your Findings in Writing

A walkthrough is only worth as much as your documentation. Verbal requests to a busy builder do not preserve a warranty claim; a paper trail does. To protect your claim, notify the builder in writing. Many limited warranties require written notice within a set window — for example, within 30 days of discovering a defect — so check your specific document and do not sit on findings.

1. Compile a single, itemized list of every defect, organized by room, with photos.
2. Attach your independent inspector's report as supporting evidence.
3. Reference your warranty's notice requirements and deadline in the letter.
4. Send it by certified mail with return receipt so you have proof of the date the builder received it.
5. Keep a full copy of everything, and log the date you sent it and the date the builder received it.
6. Follow up in writing on scheduling, and document the repairs when they are completed.

Tennessee-Specific Protections Behind Your Warranty

Your builder's written warranty is your first line of defense, but Tennessee law gives you additional backstops — and one important deadline.

Tennessee recognizes an implied warranty of habitability for new homes under Dixon v. Mountain City Construction Co., 632 S.W.2d 538 (Tenn. 1982). Under Dixon, the builder-vendor warrants that the dwelling is sufficiently free from major structural defects and built in a workmanlike manner meeting the standard of quality prevailing at the time and place of construction. This doctrine overrides caveat emptor — the old "buyer beware" rule — and can apply even if it is not written into your contract.

There is a clock on the legal side, too. Tennessee's four-year statute of repose (T.C.A. § 28-3-202) bars most actions for construction deficiencies brought more than four years after substantial completion of the improvement. Translation: waiting years to raise a defect can extinguish your legal remedy entirely. That is one more reason the discipline of documenting and pursuing problems early — starting with the month-11 walkthrough — is not just good housekeeping, it is legal self-protection.

You can also verify the builder standing behind your warranty. Tennessee requires a state Contractor's license, issued by the Board for Licensing Contractors within the Department of Commerce & Insurance, for any project of $25,000 or more. Before you escalate a warranty dispute, it is worth confirming your builder's license status through the state. None of this is legal advice — for a genuine dispute, talk to a Tennessee construction attorney — but knowing these protections exist changes how confidently you can hold your builder to the standard.

Your Sumner County / Middle Tennessee Action Plan

The month-11 walkthrough matters everywhere, but it matters more in a market building as fast as ours. Sumner County — Gallatin, Hendersonville, White House, Portland, Cottontown — is one of Middle Tennessee's fastest-growing new-build markets, with Gallatin described as one of the county's most active new-construction markets. The county levies an Adequate Facilities Tax of $0.70 per square foot on new residential construction, earmarked for schools (Sumner County, per its 1999 authorizing Private Act), and Hendersonville became the first Sumner municipality to add a standalone city impact fee — a $6,000 flat fee on new single-family homes ($4,000 to roads, $2,000 to parks), effective April 1, 2026 (per the City of Hendersonville ordinance passed February 2026, as reported by WSMV). Those figures are a proxy for how much construction is happening here. When homes go up fast to meet demand, the month-11 punch list is not paranoia; it is the appropriate level of care.

For reference, residential permits and inspections for much of the county route through the Sumner County Building & Codes Department at 355 N. Belvedere Drive, Room 208, Gallatin, TN 37066 — the same office that handled the permitting on your build.

Frequently Asked Questions

How much does an 11-month builder-warranty inspection cost?

Typically about $250 to $600, rising to roughly $650 to $1,000 in higher-cost markets. Many inspectors offer a discount when the month-11 visit is bundled with the pre-drywall and final new-construction inspections, so ask about a package if you are booking early.

Do I really need an inspection if my home is brand new?

New does not mean flawless. Per NAR reporting, 65% of homebuyers who inspected their newly built homes found issues, and 24% said their home did not pass the first inspection. An independent inspector works for you and produces a written report that carries weight in a warranty claim.

What does the one-year workmanship warranty actually cover?

On a typical 2-10 structure, the one-year "fit and finish" coverage includes defects in cabinets, countertops, door panels, exterior siding, hardwood floors, ceramic tile, drywall, interior trim, paint, and fireplaces, and it runs one year from the closing or coverage date. Mechanical systems generally carry two years and major structural components ten.

Are settling cracks covered, or are they just normal?

Some cracking is normal in the first year. NAHB's Residential Construction Performance Guidelines set the tolerances: as a general benchmark, drywall stress cracks should not exceed roughly 1/16 inch, and builders typically repair cracks over 1/8 inch wide and nail pops one time only, usually near the end of the first year. Measure and photograph anything approaching that width.

How do I make sure my warranty claim actually sticks?

Notify the builder in writing — many limited warranties require written notice within a set window, such as 30 days of discovering a defect. Send it by certified mail with return receipt and attach photos and your inspector's report. Keep copies of everything.

What if my builder refuses to fix a legitimate defect?

Tennessee's implied warranty of habitability (from Dixon v. Mountain City Construction Co.) requires that a new home be free from major structural defects and built in a workmanlike manner, and it can apply even without written contract language. You can also verify your builder's state Contractor's license (required for projects of $25,000 or more). Because Tennessee's four-year statute of repose can bar late claims, do not wait — and for a real dispute, consult a Tennessee construction attorney.
