Most builder warranties follow a 1-2-10 structure: one year for workmanship and materials, two years for major mechanical systems, and ten years for structural defects. The exact length depends on your state’s laws, your purchase contract, and whether a third-party warranty provider is involved.
Under the Federal Trade Commission’s guidance, no single federal statute forces every builder to offer a warranty on a new home. Instead, state laws set the minimum requirements — and they vary wildly, from zero mandatory coverage in some states to a full 10-year warranty in others. According to a 2023 InterNACHI survey covering 1,200 inspections, 86% of new homes built after 2021 had at least one major defect or code violation. That means understanding your builder warranty is not optional — it is a financial necessity.

What a Builder Warranty Actually Protects
A builder warranty is a written or implied promise from the company that built your home. It guarantees that construction meets certain quality standards for a set period after you take ownership. This is not the same as a home warranty plan you can buy from a service company — a builder warranty is tied to the original construction.
The warranty typically starts on the date of closing or the date of first occupancy, whichever comes first. Coverage is considered “limited” because it excludes damage from homeowner neglect, natural disasters, and normal wear and tear. If your foundation cracks because of a construction defect, that is covered. If your drywall cracks because you failed to control humidity, that is not.
Builders can offer their warranty directly or back it with a third-party warranty company. The difference matters: a builder-direct warranty is only as reliable as the builder’s ability to stay in business. A third-party warranty from companies like StrucSure or 2-10 HBW provides insurance-backed coverage that survives even if the builder goes bankrupt.
The 1-2-10 Warranty Breakdown
The 1-2-10 model is the most common structure for new home builder warranties across the United States. It divides coverage into three tiers based on what part of the home is affected and how long each component is protected.
Year One: Workmanship and Materials
During the first year, the builder warrants that all workmanship and materials meet established performance standards. This covers the broadest range of items in the home: siding, stucco, drywall, paint, doors, trim, cabinets, countertops, and flooring. If a door does not close properly, if paint peels, or if drywall cracks appear — these are first-year warranty items.
This is the most critical window because cosmetic and workmanship issues show up fast. Once the first year ends, builders are no longer responsible for these surface-level problems.
Years One Through Two: Mechanical Systems
The two-year coverage protects the delivery systems inside your home. This means the wiring, piping, and ductwork in your electrical, plumbing, heating, cooling, and ventilation systems. If your HVAC ductwork was poorly sealed and loses 50% efficiency, or if a plumbing joint fails inside a wall, these fall under the two-year warranty.
This tier does not cover the equipment itself (like your furnace or water heater), which typically falls under the manufacturer’s separate warranty. It covers only the installed distribution systems the builder put in place.
Years One Through Ten: Structural Defects
The 10-year warranty covers major structural defects — problems that make the home unsafe for occupancy or put the owner in danger. Covered structural components include:
- Foundation systems and footings
- Floor framing systems
- Load-bearing walls and partitions
- Roof framing systems
- Beams, headers, girders, and lintels
- Structural columns
A roof that could collapse, a foundation wall that cracks and shifts, or a load-bearing beam that fails — these all qualify. A cosmetic crack in the drywall or a squeaky floor does not.
| Warranty Tier | What It Covers |
|---|---|
| 1 Year — Workmanship & Materials | Siding, stucco, drywall, paint, doors, trim, cabinets, flooring, fixtures |
| 2 Years — Mechanical Systems | Wiring, piping, ductwork for HVAC, plumbing, and electrical |
| 10 Years — Structural Defects | Foundation, framing, load-bearing walls, roof structure, beams, columns |
Why Federal Law Does Not Mandate Builder Warranties
There is no federal law that requires residential home builders to provide a warranty. The Magnuson-Moss Warranty Act, which governs warranties on consumer products, applies only to “tangible personal property.” A home is real property — not personal property — so the Act does not cover it.
The Sixth Circuit confirmed this in Bennett v. CMH Homes (2014), ruling that even a manufactured home placed on land is not a “consumer product” under Magnuson-Moss. Senator Moss himself stated during the Act’s passage in 1974 that a house would not qualify. This means new home buyers cannot sue builders under federal warranty law the way they can sue an appliance manufacturer.
Because federal law leaves this gap, state legislatures and state courts fill it. Some states require written warranties by statute. Others rely on implied warranties created through court decisions. A few states provide almost no mandatory protection at all.
State Laws That Control Your Builder Warranty
Builder warranty requirements differ dramatically from state to state. Some states mandate no warranty at all. Others require a full 10-year warranty backed by a state fund. Knowing your state’s law is the single most important step a new home buyer can take.
States With Mandatory Warranty Statutes
New Jersey has one of the strongest builder warranty laws in the country. The state requires 10-year warranty coverage against defects in materials, workmanship, and systems. During the first year, everything is covered — systems, workmanship, materials, and structural defects. Years one through two cover mechanical, electrical, plumbing systems, and major structural defects. Years three through ten cover only major structural defects. New Jersey also maintains a State New Home Warranty Security Fund that pays for repairs if a builder refuses or cannot act.
Florida enacted Florida Statute §553.837, effective July 1, 2025, creating a mandatory, transferable one-year warranty for all newly constructed residential homes. The warranty covers defects in equipment, materials, or workmanship that result in a material violation of the Florida Building Code. Builders must remedy covered defects at their own expense.
Louisiana follows a 1-2-5 structure under the New Home Warranty Act. One year covers defects from noncompliance with building standards. Two years covers plumbing, electrical, heating, cooling, and ventilation. Five years covers major structural defects including foundations. Homeowners must send written notice to the builder by certified mail within one year of discovering a defect, or they risk forfeiting their claim entirely.
Texas recently changed its rules. The state traditionally imposed a 10-year statute of repose on residential construction claims. But effective June 9, 2023, the legislature shortened the repose period to six years for detached one- and two-family homes and townhomes — but only if the builder provides a written warranty that includes 1-year workmanship, 2-year systems, and 6-year structural coverage. If the builder does not provide that warranty, the full 10-year period still applies.
Connecticut enacted the New Home Warranties Act, which requires that every new home be free from faulty materials, constructed in a workmanlike manner, and fit for habitation at the time of delivery. This covers single-family dwellings and conversion condominium units.
Colorado provides implied warranties of good workmanship and habitability to every new home buyer automatically. The statutory warranty period runs two years after discovery of a defect, with a full six-year window to make claims.
| State | Warranty Type |
|---|---|
| New Jersey | Mandatory 1-2-10 with state security fund |
| Florida | Mandatory 1-year minimum (effective July 2025) |
| Louisiana | Statutory 1-2-5 under NHWA |
| Texas | 1-2-6 (with written warranty) or 10-year repose |
| Connecticut | Statutory implied warranty for new homes |
| Colorado | Implied warranty; 2-year discovery + 6-year claim window |
Third-Party Warranty Programs That Back Your Builder
When a builder offers a third-party warranty, a separate insurance company guarantees the coverage. This protects you if the builder goes out of business, refuses to make repairs, or disputes your claim. The two largest providers in the U.S. are 2-10 Home Buyers Warranty (2-10 HBW) and StrucSure Home Warranty.
2-10 Home Buyers Warranty
2-10 HBW provides 1 year of workmanship coverage, 2 years of distribution system coverage, and a full 10 years of insurance-backed structural defect coverage. Builders must register as members of the program. The structural coverage is a direct warranty — meaning 2-10 HBW is the responsible party, not the builder.
StrucSure Home Warranty
StrucSure’s 1-2-10 warranty operates similarly. The one-year and two-year tiers act as builder surety — StrucSure steps in only if the builder defaults. The 10-year structural warranty is a direct warranty from StrucSure. If a major structural defect occurs within 10 years, StrucSure will repair, replace, or pay for it regardless of the builder’s status. Both the two-year and 10-year components are required to satisfy HUD requirements for certain loan programs.
| Feature | 2-10 HBW |
|---|---|
| Workmanship Coverage | 1 year |
| Systems Coverage | 2 years |
| Structural Coverage | 10 years (insurance-backed) |
| Who Pays for Structural Claims | 2-10 HBW directly |
| Feature | StrucSure |
|---|---|
| Workmanship Coverage | 1 year (builder surety) |
| Systems Coverage | 2 years (builder surety) |
| Structural Coverage | 10 years (direct warranty) |
| Who Pays for Structural Claims | StrucSure directly |
The Implied Warranty of Habitability Explained
Even if a builder’s written warranty has expired or was never provided, most states recognize an implied warranty of habitability. This is a court-created protection that exists automatically when you buy a newly constructed home. It guarantees the home was built in a workmanlike manner and is safe to live in.
Since the 1970s, courts in nearly all 50 states have recognized this doctrine. It shifts the risk of hidden construction defects from the buyer to the builder. You do not need to negotiate it into your contract — it exists by operation of law.
The implied warranty protects against latent defects — problems hidden inside walls, foundations, or systems that a buyer could not reasonably discover during a walkthrough. It does not cover aesthetic issues or problems caused by the homeowner’s own actions.
Can a Builder Make You Waive This Warranty?
In most states, no. The Arizona Supreme Court made this clear in Zambrano v. M&RC II LLC (2022). The builder had included a waiver of the implied warranty of habitability in the purchase agreement. The court struck it down, holding that public policy protecting homebuyers from defective homes outweighed the builder’s interest in limiting liability.
Pennsylvania’s Superior Court extended implied warranty protection even further. In Conway v. The Cutler Group (2012), the court ruled that a subsequent purchaser — someone who buys the home secondhand — can still pursue an implied warranty claim against the original builder. The court reasoned that requiring a direct contractual relationship would create “potential inequities” when latent defects appear years after the original sale.
Illinois took a narrower approach. In the Sienna Court decision, the Illinois Supreme Court held that buyers of newly constructed homes cannot sue subcontractors for breach of implied warranty — only parties with direct contractual relationships. However, subsequent purchasers can still pursue claims against the original developer.
Utah’s Supreme Court recognized the implied warranty for all new home construction. To prove a breach in Utah, a buyer must show: (1) purchase of a new residence from a builder-vendor, (2) a latent defect existed, (3) the defect appeared after purchase, (4) it was caused by improper design, material, or workmanship, and (5) it created a safety issue or made the home unfit for habitation.
Three Real-World Scenarios Every Homebuyer Should Know
Scenario 1: The Leaking Pipe in Month 14
Maria buys a new home with a standard 1-2-10 warranty. Fourteen months after closing, she discovers a plumbing leak inside a bathroom wall. She worries that the one-year workmanship warranty has expired.
| Maria’s Situation | What Happens |
|---|---|
| Plumbing leak discovered at month 14 | Covered — plumbing piping falls under the 2-year systems warranty, not the 1-year workmanship tier |
| Maria files a claim with the builder | Builder must repair or replace the defective piping at no cost |
| Maria hires her own plumber first | Claim likely denied — unauthorized repairs void coverage |
| Maria waits until month 25 to file | Claim denied — the 2-year systems warranty has expired |
Scenario 2: The Foundation Crack in Year 7
James notices a crack running through his foundation wall seven years after closing. His builder went out of business three years ago. James has a third-party 10-year structural warranty through StrucSure.
| James’s Situation | What Happens |
|---|---|
| Foundation crack at year 7 | Covered — foundation systems fall under the 10-year structural warranty |
| Builder is out of business | StrucSure pays directly as the warranty insurer |
| Crack is cosmetic only, no structural movement | Claim denied — must meet the definition of a “major structural defect” |
| James failed to maintain proper drainage | Claim denied — homeowner neglect is excluded from coverage |
Scenario 3: The Florida Buyer With No Written Warranty
Carla buys a new home in Florida in August 2025. Her small-volume builder did not include any warranty in the purchase contract.
| Carla’s Situation | What Happens |
|---|---|
| No written warranty in the contract | Florida Statute §553.837 provides a mandatory 1-year warranty automatically |
| Defect violates Florida Building Code | Builder must remedy the defect at their own expense |
| Defect is cosmetic but no code violation | Not covered — the statute requires a “material violation” of the building code |
| Carla sells the home at month 8 | New buyer inherits the warranty — it is transferable under the statute |
Mistakes That Get Builder Warranty Claims Denied
Homeowners lose valid warranty claims every year because of avoidable errors. Research shows that 81% of construction deficiencies stem from shoddy workmanship — meaning defects are common, but getting them fixed requires following the right process.
Repairing defects before the builder inspects. If you hire your own contractor to fix a problem before giving the builder or warranty company a chance to investigate, your claim will almost certainly be denied. The warranty provider has a right to evaluate the defect and choose the repair method. The only exception is an emergency like a burst pipe.
Failing to document defects in writing. Verbal complaints are not enough. Louisiana’s New Home Warranty Act, for example, requires written notice by certified mail within one year of discovering a defect. Failing to meet this requirement can forfeit your entire claim.
Using unauthorized technicians for repairs. Most builder warranties and third-party programs require you to use the builder’s approved contractors or the warranty company’s service network. Having someone else do the work — or doing it yourself — makes that item ineligible for future coverage.
Neglecting routine maintenance. If the warranty company finds that you did not maintain an appliance or system in a way that could have prevented the failure, your claim gets denied. Keep records of all maintenance performed.
Missing the filing deadline. Each warranty tier has a strict expiration date. A plumbing claim filed at month 25 is too late for the 2-year systems warranty — even by one month. Track your warranty dates from day one.
Confusing cosmetic issues with structural defects. A hairline crack in drywall is not a structural defect. Homeowners who file structural claims for cosmetic problems waste time and credibility. Know what qualifies as “major structural” before you file.
Pros and Cons of Builder Warranties
| Pros | Cons |
|---|---|
| Covers expensive structural repairs for up to 10 years, protecting your largest investment | Cosmetic and workmanship coverage expires after just 1 year, when many defects have not yet appeared |
| Third-party warranties survive builder bankruptcy, giving you a backup | Builder-direct warranties are worthless if the builder goes out of business |
| Transferable warranties increase your home’s resale value and attract buyers | Transfer requirements often include fees and paperwork that homeowners overlook |
| Implied warranty of habitability exists in most states even without a written warranty | Some states allow builders to limit implied warranty claims through contract language |
| Provides a structured claims process with defined performance standards | Claims can be denied for minor procedural errors like failing to send written notice |
Do’s and Don’ts for Protecting Your Builder Warranty
| Do’s | Don’ts |
|---|---|
| Do read your entire warranty document before closing — know every deadline, exclusion, and filing requirement | Don’t assume the builder will remind you when coverage is about to expire — they benefit from your inaction |
| Do send all defect notices in writing by certified mail, even if your state does not require it | Don’t report defects verbally or by text message — these create no verifiable record |
| Do photograph and date every defect the moment you notice it, creating a timeline of evidence | Don’t wait to see if a problem “gets worse” — delays can push you past your filing deadline |
| Do allow the builder or warranty company to inspect and choose the repair method first | Don’t hire your own contractor before giving the warranty provider an opportunity to investigate |
| Do keep records of all home maintenance, including HVAC filter changes, gutter cleaning, and drainage upkeep | Don’t neglect routine maintenance — this is the most common reason warranty claims are denied |
| Do verify whether your warranty is transferable if you plan to sell within the coverage period | Don’t assume the warranty automatically transfers — many require written notice and a fee |
How to File a Builder Warranty Claim Step by Step
Filing a warranty claim is a process with specific steps, and missing any one of them can result in a denied claim. The process below applies to most builder and third-party warranty programs.
Step 1: Identify the defect category. Determine whether the issue is workmanship (Year 1), a mechanical system (Year 2), or structural (Year 10). This tells you which warranty tier applies and whether you are still within the coverage period.
Step 2: Document everything. Take dated photos and videos of the defect. Write a detailed description of what you see, when it started, and how it affects your home. Save all records in a dedicated file.
Step 3: Send written notice to the builder. Use certified mail with return receipt requested. Include your name, address, closing date, a description of the defect, photos, and the specific warranty tier you believe covers the issue. Keep a copy of everything you send.
Step 4: Allow reasonable time for inspection. The builder or warranty company has the right to send their own inspector to evaluate the defect. Do not make repairs yourself during this period unless there is an active emergency threatening safety or property.
Step 5: Review the builder’s response. The builder may agree to repair, deny the claim, or offer a partial remedy. If they agree, confirm the repair timeline in writing. If they deny the claim, request a written explanation citing the specific warranty exclusion.
Step 6: Escalate if needed. If the builder denies a valid claim, contact your third-party warranty provider (if applicable), your state’s consumer protection office, or a construction law attorney. Some states, like New Jersey, have a state warranty security fund that pays for repairs when builders default.
