Builders Say Construction Defect Fears Are “Overblown.” Their SEC Filings Say Otherwise.

By: Ryan M. Lockman

A recent Wall Street Journal piece on construction defect litigation gives space to a familiar industry framing: builders are quoted calling the fears “overblown,” and a defense attorney describes claims as “tangential at best,” attributing the surge to what the piece calls a “growing hysteria” around mold.

That may be what homebuilders tell reporters. It is not what they tell the Securities and Exchange Commission.

Public homebuilders, like any publicly traded company, must disclose material risks to investors. The WSJ article specifically names D.R. Horton and Lennar, and their 10-K filings tell a different story than “hysteria”: a known, quantified and growing cost of doing business.

What the Filings Show

D.R. Horton’s fiscal 2025 10-K doesn’t hedge: “Our business is subject to home warranty and construction defect claims and other litigation that can be significant.” It acknowledges that subcontractors “occasionally do not meet adequate quality standards.”

The numbers:

• Legal contingency reserves hit $1.1 billion as of September 30, 2025, up from $949.6 million the year before, with roughly 98% tied to construction defect matters.
• Annual legal contingency expenses nearly doubled in two years: from $139.7 million in FY2023 to $240.1 million in FY2025.
• Since June 1, 2021, D.R. Horton has been “almost exclusively self-insured” for construction defect exposure—meaning the company, not an insurer, absorbs most of these costs. Those incentives matter when homeowners are asking the company to investigate and pay to correct alleged defects.

Lennar’s filing echoes this. Its self-insurance reserve grew from $277.4 million to $336.9 million in fiscal 2025, a jump the WSJ noted but didn’t tie back to why that reserve exists. Lennar also uses a third-party actuary to model these liabilities and paid out roughly $266 million in warranty claims in fiscal 2025 alone, with adjustments “primarily” tied to “specific claims in certain of the Company’s homebuilding communities.”

D.R. Horton and Lennar aren’t outliers, either. For example, Toll Brothers’ fiscal 2015 10-K disclosed a stucco-related warranty reserve that grew from $54 million to $80.3 million in a single year, tied to water damage in Pennsylvania and Delaware communities. By the end of its 2016 fiscal year, that number had risen to $298.0 million in remaining liability for known and unknown stucco and water intrusion claims, per its Q3 2017 10-Q.

Where Mold Fits In

Neither filing uses the word “mold.” Both fold it into the same broad “warranty and construction defect” bucket as every other quality failure. The WSJ itself explains why: “construction defects can cause mold growth,” from bad HVAC sizing, improper installation of the weather-resistant barrier or poor attic ventilation. Having litigated residential construction defect claims for years, I have seen firsthand that mold is often a symptom of a larger construction problem, not a separate legal theory. Water intrusion, building envelope failures, improper ventilation and other defects can create the conditions that allow mold to develop, sometimes in areas of a home that a homeowner cannot see. This is exactly how the Louisiana suits against D.R. Horton and the Seminole Tribe’s suit against Lennar (more than 450 homes with water intrusion and mold) are framed in the WSJ article. In the construction defect cases I have litigated, mold is often a symptom of an underlying construction problem, not the problem itself. Water intrusion, improper ventilation or other construction failures can create the conditions that allow mold to develop.

The Disconnect

Builders don’t set aside $1.1 billion, or grow legal expenses 73% in two years, to defend “tangential” claims. D.R. Horton says its reserves are based on “historical experience” and revised as “circumstances of individual pending claims and historical data and trends change.” This is a company tracking real claim frequency and building it into a worsening forecast.

That financial reality is consistent with what I have seen litigating residential construction defect claims. Homeowners may initially be told that a leak, mold growth or another problem is isolated or the result of maintenance, even when further investigation reveals a more significant construction issue.

Before a single lawsuit is filed, the nation’s largest builders have already publicly told their shareholders that construction defects are common, costly and rising—and that they’ve shifted from insurance to self-funding. That’s not a story about homeowner hysteria.

What It Means For You

If you’re a homeowner dealing with mold, water intrusion or other signs of a construction defect, the builder’s own financial disclosures may already reflect an expectation that claims like yours will happen, and that there is a reserve set aside to pay for them.

That matters when a homeowner is told that a problem is minor, isolated or simply a maintenance issue. The financial disclosures discussed above show that major homebuilders themselves recognize construction defect and warranty claims as a significant business risk. Homeowners should not assume that a builder’s initial response is the final word on what is causing a problem or what rights they may have.

A builder’s warranty also may not be the beginning and end of a homeowner’s rights. Construction defect claims can involve warranties, contracts, consumer protection laws and other legal remedies, all of which may be subject to different notice requirements and deadlines. If you believe your home may have a construction defect, consider contacting a construction defect attorney, including the attorneys at Horn Williamson & Collins, to understand your rights and the steps you can take to protect them.
