In most cases, yes, your builder is responsible for foundation problems in a newly built home, and the question of whether your builder is responsible for foundation problems usually comes down to three overlapping legal theories: the implied warranties the law imposes on every new-home builder, the written structural warranty you received at closing, and a negligence claim if the builder deviated from code or standard practice. The harder questions are how fast you have to act, whether your contract forces you into arbitration, and whether the specific damage you’re seeing fits the legal definition of a covered defect.
The Three Ways a Builder Can Be Held Responsible
Implied Warranties Every State Recognizes
Even if your purchase contract says nothing about the foundation, two doctrines protect buyers of newly built homes. The implied warranty of workmanship requires the home to be built to the standard a competent contractor would meet. Skipped soil compaction, the wrong concrete mix, or ignored drainage requirements before the slab was poured all fall inside it. The implied warranty of habitability goes further and guarantees the home is safe to live in. A foundation shifted enough that floors are uneven or walls are pulling away from the frame crosses that line.
Courts in every state recognize some version of both warranties, and in many states a builder cannot contractually waive them, even where the purchase agreement includes disclaimer language. Some states do allow waivers if they are clearly written and the buyer received something of value in exchange, so whether a waiver in your contract will hold up depends on where you live.
One important boundary: these warranties protect the buyer of new construction from the builder-vendor. If you bought a resale home from a previous owner who was not the builder, implied warranties from the original construction generally do not transfer to you, and your recourse depends mostly on what the seller disclosed.
The Written Warranty You Got at Closing
Most new-home purchases include an express written warranty, and the foundation is almost always covered longer than any other component. Workmanship items like drywall and paint typically carry one year of coverage. Mechanical systems like HVAC, plumbing, and electrical usually get two. Major structural defects, which most warranties define as problems that make the home unsafe or endanger the occupants, are typically covered for ten years.
Foundation failures almost always fall under that ten-year structural tier, but the warranty’s own definition controls. Some warranties define “structural defect” narrowly as a condition making the home unsafe for occupancy, which means cosmetic foundation cracks that don’t affect structural integrity may not qualify.1Federal Trade Commission. Warranties for New Homes
Many builders don’t back their structural warranties directly. They buy coverage through a third-party warranty company like 2-10 Home Buyers Warranty, in which case your claim goes to the insurer rather than the builder. The practical advantage is significant: the coverage survives even if the builder goes out of business during the warranty period. The tradeoff is that disputes about what qualifies are resolved through the warranty company’s own process, and disagreements outside the structural warranty are typically sent to binding arbitration.22-10 Home Buyers Warranty.

Negligence When the Builder Fell Short
Warranty claims aren’t the only option. If the builder ignored building codes, departed from the architectural plans, or deviated from standard construction practices, you may have a negligence claim. Negligence doesn’t require a warranty at all. You have to show the builder had a duty to build competently, breached that duty, and caused your foundation damage.
Code violations carry real weight. A violation alone doesn’t automatically prove negligence, but courts treat it as strong evidence the builder fell below the standard of care. If a structural engineer’s report ties specific code violations to the foundation work, that finding substantially strengthens settlement negotiations or litigation. Negligence claims matter most when the written warranty has expired or doesn’t cover your particular problem, and they can open the door to damages beyond repair costs, including diminished property value.
Why Homeowners Insurance Probably Won’t Help
Most homeowners call their insurer first and learn the claim is excluded. Standard policies contain an “earth movement” exclusion that bars coverage for damage caused by settling, shifting, sinking, or rising soil. The language is broad and typically uses “any” to encompass all earth movement, whether natural or caused by human activity like nearby construction. Policies also include an “anti-concurrent cause” provision, meaning the insurer won’t pay even if earth movement combined with another covered event. Courts have consistently upheld these exclusions.
The practical result is that foundation settlement, heaving, and cracking from soil movement fall outside what your policy will cover. For most homeowners, the builder’s warranty or a successful claim against the builder is the only realistic source of payment for repairs that can easily run $15,000 to $30,000 or more.
Deadlines That Can End Your Claim
Two separate clocks run on construction defect claims, and mixing them up is where many homeowners lose their case.
The statute of limitations starts when you discover the foundation problem, or when you reasonably should have discovered it. Diagonal cracks spreading across a basement wall or doors that suddenly won’t close start the clock. In many jurisdictions this period is as short as two years, so delay after you spot warning signs is dangerous.3Community Associations Institute. State Construction Defect Statutes of Limitation and Repose
The statute of repose is the harder deadline. It runs from the date construction was substantially completed, regardless of when you discovered the defect. If your state’s repose period is eight years and you don’t find the problem until year nine, the claim is barred even though you couldn’t have known sooner. These periods range from four to fifteen years depending on the state.3Community Associations Institute. State Construction Defect Statutes of Limitation and Repose
If the builder actively hid the defect, the statute of limitations may be tolled, meaning the clock pauses until you had a reasonable opportunity to discover the problem. The bar is higher than mere negligence. A builder who covered visible cracks with drywall before closing or falsified soil compaction reports is the kind of conduct that qualifies. You generally have to show the builder knew about the problem and took deliberate steps to prevent you from finding it.
What Your Contract Requires Before You Sue
Notice and Right-to-Repair Laws
Filing a lawsuit without following your state’s required procedures is one of the fastest ways to have your case dismissed. More than half of all states have enacted right-to-repair or notice-and-cure laws that require homeowners to give the builder formal written notice and an opportunity to inspect and fix the defect before any lawsuit can proceed.
The specifics vary, but the framework is similar. You send the builder a written notice describing the defect, the damage, and any losses. The builder has a set period to respond and can offer to make repairs, request an inspection, propose a settlement, or deny the claim. Only after that process runs its course can you file suit. A court can dismiss a lawsuit outright or stay it until you complete the required notice. Even in states without a formal statute, sending a detailed written demand by certified mail with return receipt creates a paper trail and documents when the builder was put on notice.
Mandatory Arbitration Clauses
Pull out your purchase agreement and warranty documents and look for an arbitration clause before you plan litigation. If you signed one, a judge will almost certainly require you to arbitrate. The Federal Arbitration Act makes written arbitration agreements in contracts involving commerce “valid, irrevocable, and enforceable,” and courts have consistently applied this to residential construction contracts.4Office of the Law Revision Counsel. United States Code Title 9 – Section 2
Arbitration moves faster than litigation and reduces discovery costs, but decisions are binding and almost never appealable. Upfront costs can be higher because you pay the arbitrator’s hourly rate on top of attorney’s fees, and filing fees scale with the dollar value of the dispute. You also lose the right to join a class action with other homeowners who may have the same defect from the same builder. If the arbitration language is ambiguous, contradictory, or buried in fine print, a judge may refuse to enforce it, but courts start from the presumption that the clause is valid.
Build the Evidence Before You Contact the Builder
The strength of your claim depends almost entirely on the evidence you assemble before the conversation starts. Start with a visual record. Photograph and video every crack, shift, gap, and sign of water intrusion. Include a tape measure or ruler in close-ups for scale, and take wide shots that show damage in context. Date everything. If the damage is progressing, document it again every few weeks to show the timeline.
Gather every piece of paperwork tied to the home: your purchase agreement, the builder’s written warranty, any third-party warranty documents, correspondence with the builder, inspection reports from closing, and maintenance records. Builders frequently argue that homeowner neglect caused the damage, and maintenance records counter that claim.
The single most important step is hiring a licensed structural engineer to inspect the foundation and produce a written report identifying the cause, extent, and recommended repair method. This is not the same as a general home inspection. A structural engineer’s report carries weight in negotiations and in court because it ties the defect to the construction rather than to normal wear or soil conditions. Expect to pay roughly $400 to $850 for a foundation-specific inspection and report, though fees vary by region and complexity.
What You Can Recover
If the builder is found responsible, the most common measure of damages is the cost of repair. Work involving helical piers or underpinning typically runs $1,500 to $4,000 per installed pier, with most residential projects requiring five to twelve piers and totaling $15,000 to $30,000 or more.
Repair costs aren’t necessarily the ceiling. If the damage is so severe that repairs cannot fully restore the home’s value, you may be able to recover the remaining loss as diminished property value. Courts in several states have allowed homeowners to collect both the cost of repairs and the post-repair reduction in market value, though this is harder to prove and usually requires an appraiser’s testimony. When the cost of repair would exceed the reduction in home value, courts sometimes award diminished value instead, treating full repair as economic waste.
Depending on state law and the severity of the defect, other recoverable damages can include temporary housing costs during repairs, loss of use of portions of the home, and in some states attorney’s fees if the warranty or a consumer protection statute provides for them. Emotional distress damages are rarely available in pure construction defect cases, but a builder who engaged in fraud or willful misconduct may face additional liability.
