What Foundation Problems You Must Disclose When Selling

Quick Answer

Yes, you must disclose known foundation problems when selling in virtually every U.S. state. Even "as-is" sales do not waive disclosure obligations in 13 of the 15 highest-population states. Non-disclosure of foundation issues is the most litigated residential defect category in Texas, representing 77% of disclosure lawsuits (Houzeo, September 2025).

Quick Facts

Do I Legally Have to Disclose Foundation Problems When Selling My House?

You are filling out the seller's disclosure form and you have reached the section about structural conditions. The crack in the basement wall has been there since you moved in eight years ago. The doors stick seasonally — worse in summer, fine in winter. You had a foundation company come out three years ago and they recommended $12,000 in piers, but you got a second opinion from an engineer who said the house was stable and no repair was needed. Now you are selling and wondering what — and how much — you have to put on this form.

Look at the disclosure form itself. Texas uses the TREC Seller's Disclosure Notice, which asks specific questions: "Are you aware of any defects or malfunctions in the foundation, slab, or fireplaces/chimneys?" California's Transfer Disclosure Statement requires sellers to identify "cracks in foundation, foundation settling, or other structural problems." Colorado's form requires disclosure of both current and past foundation issues — even problems that were repaired. Each state's form uses different language, but all ask whether you know of structural conditions.

The key word in every state's law is "known." You are required to disclose what you know. If you have lived in the house for 10 years and never noticed the 1/4-inch crack behind the water heater, that is genuinely unknown. But if you hired a foundation company, received a report, got a second opinion from an engineer, and have been watching the doors stick for years — you know. The disclosure form is not asking whether you think it is serious. It is asking whether you are aware of its existence.

Why This Happens

Step 1: Disclosure laws exist because foundation problems are invisible to casual observation. A buyer walking through a staged home may not notice the crack behind the curtain, the shimmed door frame, or the grading that was corrected the week before listing. State legislatures created mandatory disclosure requirements because the information asymmetry between sellers and buyers creates inherent unfairness. Foundation defects are specifically named in most state disclosure statutes because they represent the single most expensive residential repair category — the national average is $5,179 (This Old House, 2026) — and because they affect structural safety.

Step 2: State laws vary in penalties but converge on the obligation to disclose. Texas imposes the strongest penalties through the Deceptive Trade Practices Act, which allows treble damages — three times the actual damage amount — for knowing misrepresentation or omission. California Civil Code §1102.1 explicitly prohibits waiver of disclosure requirements, meaning "as-is" contract language does not release you from disclosure. Florida follows the Johnson v. Davis standard requiring disclosure of known material defects. Colorado requires disclosure of both current problems and past problems that have been repaired. Tennessee has the shortest statute of limitations at one year from closing. Oklahoma allows only actual damages, making it the most seller-friendly state.

Step 3: "As-is" does not mean "no disclosure." This is the most common and most dangerous misconception in residential real estate. "As-is" means the seller will not make repairs — it does not eliminate the obligation to disclose known defects. In 13 of the 15 highest-population U.S. states, "as-is" language does not waive mandatory disclosure requirements. Sellers who believe "as-is" protects them from disclosure obligations are exposing themselves to the same liability as sellers who actively conceal defects.

What To Do Next

Step 1: Get the correct disclosure form for your state (free). Your real estate agent should provide this, but you can also download it from your state's real estate commission website. Read the questions about structural conditions, foundation, settlement, and water intrusion carefully. Answer based on what you know, not what you hope. If you received a contractor report, an engineering evaluation, or a previous inspection report that mentioned foundation conditions, you have knowledge that must be disclosed.

Step 2: Gather all documentation of known conditions ($0 if you have records). Compile every report, estimate, repair invoice, warranty, and correspondence related to your foundation. This includes the contractor who recommended piers you did not install, the engineer who said no repair was needed, and the home inspection report from when you purchased. If you chose not to repair based on engineering advice, disclose that — it demonstrates informed decision-making, not neglect. The PE evaluation that said no repair was needed is a disclosure asset, not a liability.

Step 3: Disclose proactively and attach documentation. Rather than answering the minimum required questions, attach your documentation package to the disclosure form. This approach has two benefits: it satisfies your legal obligation beyond question, and it frames you as a transparent seller — which 75% of buyers respond positively to when repairs are documented (HAR.com, August 2025). If no repair was performed because none was needed, the PE letter explaining that conclusion is your strongest disclosure document. The $300–$780 cost of a PE evaluation (HomeAdvisor, 2025) is insignificant compared to the potential cost of a disclosure lawsuit.

When You Don't Need Repair

If a licensed Professional Engineer has evaluated your foundation and concluded that observed conditions are cosmetic and within normal tolerances, you do not need to repair before selling — but you do still need to disclose. Disclosure and repair are separate obligations. Disclosing a cosmetic condition with an attached PE letter stating no structural concern is a stronger position than repairing a non-issue and disclosing the repair history. If your PE confirms stability, your cracks are under 1/16 inch, and your doors and windows operate normally, the disclosure obligation is satisfied by telling the buyer what you know and providing the engineering documentation. Save your money.

Related Issues to Check

Water intrusion through foundation cracks. Many state disclosure forms have separate questions about water intrusion, flooding, and moisture in basements or crawl spaces. If foundation cracks have ever admitted water — even once during a heavy rain — this is a separate disclosable condition. Water intrusion from foundation cracks is both a structural concern and a habitability concern that triggers additional disclosure requirements.

Previous repairs by prior owners. If you received disclosure of prior foundation repairs when you purchased, that information follows the property — you are now obligated to disclose what you were told. Destroyed documentation does not eliminate knowledge. If you know the house had piers installed before you bought it, that is disclosed even if you no longer have the paperwork.

Neighboring property conditions. In some states, known neighborhood conditions that affect your property — such as a subdivision-wide drainage problem, a history of sinkhole activity, or construction that caused your foundation damage — are disclosable material facts. If every house on your street has foundation problems from the same soil conditions, that context is relevant to a buyer's decision.

Frequently Asked Questions

What if I didn't know about the problem? You cannot disclose what you genuinely do not know. But courts evaluate "knowledge" broadly — if you repainted over cracks, replaced doors because they did not fit, or ran dehumidifiers continuously, a court may find you were aware of symptoms you chose not to investigate. Willful ignorance — deliberately avoiding learning about a condition — is treated the same as knowledge in most jurisdictions.

Does an as-is sale protect me? No, not from disclosure obligations. "As-is" means you are not obligating yourself to repair. It does not mean you can withhold information about known defects. In 13 of 15 highest-population states, mandatory disclosure requirements override "as-is" contract language. Texas courts have specifically ruled that "as-is" does not eliminate DTPA liability for knowing non-disclosure.

What about old cracks I thought were cosmetic? Disclose them. Your assessment of their severity is not the question — the question is whether you are aware of their existence. Describe what you see: "Hairline crack in northwest basement wall, present since at least 2018, no change observed." If you had an engineer evaluate them and confirm they are cosmetic, attach that report. The disclosure obligation covers known conditions, not just known problems.

Can a buyer sue me after closing? Yes, within the statute of limitations for your state. Texas allows up to four years for DTPA claims. California allows three years for fraud-based claims. Tennessee has the shortest window at one year. The strength of a buyer's claim depends on whether they can show you knew about a condition and did not disclose it. Complete, proactive disclosure with documentation is your strongest legal defense.
