Homeowners searching for a Lennar homes class action lawsuit will find several proposed class actions filed in recent years, but no certified nationwide class and no sweeping settlement. The claims cluster around construction defects — water intrusion, mold, cracked stucco, roofing failures, and structural framing problems — along with misleading model homes and aggressive use of mandatory arbitration. That last point matters most for anyone hoping to join a group suit: Lennar’s purchase contracts require individual arbitration and prohibit class participation, and courts have largely enforced those clauses.
Proposed Class Actions Currently on File
Thompson v. CalAtlantic Group and Lennar (South Carolina)
Two Summerville, South Carolina homeowners filed a proposed class action in April 2024 against CalAtlantic Group and Lennar Corporation over structural defects in “Georgetown model” homes. The complaint alleges a deficient I-joist on the second floor caused sagging and uneven flooring, and that the builders refused to provide architectural plans or work orders when asked.1ClassAction.org. CalAtlantic, Lennar Sued Over Apparent Structural Defects Allegedly Plaguing South Carolina Homes It brings claims for breach of contract, negligence, breach of the implied warranty of habitability, and violations of the South Carolina Unfair Trade Practices Act.
The proposed class covers South Carolina owners of Georgetown model homes built by the defendants who discovered the floor defect within the prior three years or have not yet discovered it. CalAtlantic removed the case to federal court in Charleston shortly after filing.2ClassAction.org. Thompson et al. v. CalAtlantic Group LLC et al., Notice of Removal No class certification ruling or settlement had been reached in available records.
Schwarz v. Lennar Homes (Florida)
Steve Schwarz and Brian Heymann filed a class action breach of contract suit against Lennar Corporation and several affiliated entities in Osceola County, Florida in late 2024. Lennar removed it to the U.S. District Court for the Middle District of Florida in March 2025. The judge dismissed the original complaint without prejudice in August 2025 as a “shotgun pleading,” meaning the complaint was too disorganized to clearly state what the defendant did wrong. The plaintiffs filed an amended complaint. Docket records show the case marked terminated in December 2025, though later entries reference a mediation conference set for September 2026 and a jury trial for January 2027.3CourtListener. Schwarz v. Lennar Homes LLC, Case No. 6:25-cv-00466
Elhendi v. Lennar Homes of California
A 2018 class action filed in Los Angeles County Superior Court targeted Lennar’s model homes. Plaintiff Mohamed Elhendi alleged that the model he was shown before purchasing had a bathroom and shower layout “completely different” from what was actually built, and that the delivered bathroom was not ADA compliant, allegedly costing thousands to fix.4Truth in Advertising. Elhendi v. Lennar Homes of California, Class Action Complaint The complaint charged violations of California’s False Advertising Act and Unfair Business Practices Act. The outcome is not available in public records reviewed for this article.
The Seminole Tribe Suit: Not a Class Action, But the Largest Active Case
The biggest active case against Lennar is not a class action but a suit by the Seminole Tribe of Florida, which paid the company roughly $300 million to build homes across six reservations in Broward, Hillsborough, St. Lucie, Lake, Glades, Hendry, and Collier counties.5Miami Herald. Seminole Tribe Sues Lennar Over Defective Homes on Tribal Land The tribe filed in Broward County circuit court in March 2025, alleging more than 550 of the homes are unsafe to live in.6Tribal Business News. Seminole Tribe Sues Builder Over Alleged Defects in 550 Tribal Homes
According to the tribe’s attorney, William Scherer, every house suffers water intrusion and mold. Other reported problems include cracked stucco, buckling tiles, electrical failures, air conditioning breakdowns, and roofing so deficient that every roof needs replacing.7CBS News Miami. Seminole Tribe Sues Lennar Homes After Alleging Defective Construction Scherer described conditions as a “horror show” and said many tribal members had been forced out due to mold exposure.8WPLG Local 10. Attorney for Seminole Tribe Discusses Lawsuit Against Lennar Homes
An amended complaint filed in late summer 2025 accused Lennar of “intentional misconduct and fraud” and demanded a jury trial. The tribe seeks damages in the hundreds of millions of dollars, covering property losses, repair costs, temporary relocation, and healthcare costs tied to mold. Mediation collapsed, and Lennar has pushed to send the dispute to arbitration while the tribe argues sovereign immunity and the terms of the original construction agreement keep the case in court.6Tribal Business News.

Why Most Lennar Class Claims Never Reach a Courtroom
Lennar’s purchase agreements, and even its website terms of service, contain mandatory arbitration clauses that require disputes to be resolved individually and explicitly prohibit class action participation.9Lennar. Terms and Conditions For a buyer, that usually means giving up any right to join a group lawsuit and instead paying to arbitrate alone.
Florida courts have enforced these clauses even against homeowner associations suing on behalf of members. In a 2021 case involving the Martinique at the Oasis community in Homestead, where the HOA sued Lennar over defective exterior wall cladding on 241 townhouse units, Florida’s Third District Court of Appeal ruled the association was bound by the arbitration agreements its individual members had signed at purchase.10Third District Court of Appeal of Florida. Lennar Homes, LLC v. Martinique at the Oasis Neighborhood Association, Inc.
Texas has gone the same way. In Lennar Homes of Texas, Inc. v. Rafiei, a homeowner seriously injured by an exploding garbage disposal challenged the arbitration clause as unconscionable because arbitration costs could exceed $60,000. The Texas Supreme Court reversed a lower ruling in his favor in a unanimous per curiam opinion in April 2024, holding that because the contract contained a “delegation clause” sending threshold questions to the arbitrator, the homeowner had to prove specifically that arbitrating that narrow gateway question was cost-prohibitive, not that the overall arbitration would be expensive.11Texas Civil Justice League. SCOTX Reverses Court of Appeals Judgment Holding Arbitration Too Cost-Prohibitive to Homeowner The ruling set a high evidentiary bar for Texas homeowners trying to escape a Lennar arbitration clause on cost grounds.
Repair offers can carry their own restrictions. In Minnesota’s Twin Cities, nearly 200 newly built homes in the Haven Ridge and Skye Meadows subdivisions had leaking windows traced to a manufacturing problem. When Lennar offered to fix them, homeowners told Fox 9 investigators the company required non-disclosure agreements as a condition of repairs, with one homeowner reporting the NDA threatened fines of thousands of dollars for even mentioning the company’s name. Lennar said NDAs were only required when it went “above and beyond” standard warranty repairs. Engineering tests reviewed by Fox 9 showed water continued seeping through windows even after the company’s cement-bonding fix was applied.12Fox 9.

Settlements Lennar Has Actually Paid
Large class settlements tied directly to construction defects have been rare, partly because arbitration clauses block class formation. Money has moved in other cases.
- San Francisco Shipyard environmental settlement, $6.3 million, 2022: Current and former homeowners sued Lennar and co-developer FivePoint over the fraudulent cleanup of toxic and radioactive contamination at the former Hunters Point Naval Shipyard. A federal court approved the class settlement in March 2022, with individual payouts ranging from hundreds to tens of thousands of dollars. Separate litigation continued against Tetra Tech, the cleanup contractor primarily responsible for the fraud.13CPM Legal. Shipyard Homeowners Win Court Approval of $6.3 Million Settlement With Lennar and FivePoint
- Universal American Mortgage Company False Claims Act settlement, $13.2 million, 2018: Lennar’s mortgage subsidiary agreed to pay $13.2 million to resolve DOJ allegations it knowingly submitted unqualified loans for FHA insurance between 2006 and 2011, improperly incentivizing underwriters and skipping required quality control reviews. A whistleblower former employee received nearly $2 million. The company did not admit liability.14U.S. Department of Justice. Universal American Mortgage Company LLC Agrees to Pay $13.2 Million to Resolve False Claims Act Allegations
A separate Florida case, Alaqua Lakes, involved negligent design and construction of roadways in a 500-home community. A jury awarded $3.8 million in 2018 against the community’s developer Taylor Morrison, not Lennar; with prejudgment interest the judgment grew to $7.36 million, and the developer ultimately paid $8.6 million after Florida’s Fifth District Court of Appeal affirmed in August 2020.15Business Trial Group.

What Homeowners Are Alleging and Where to Turn
The defects alleged across Lennar cases fall into familiar categories: water intrusion and mold, cracked foundations, roofing failures, stucco separation, plumbing and HVAC problems, and structural framing issues such as insufficient floor joists. Some homeowner contracts also require buyers to waive state-law implied warranties of habitability and include liquidated damages clauses that let the builder keep deposits if a buyer backs out after discovering problems.
As of 2026, law firms including Sauder Schelkopf are conducting nationwide investigations into Lennar construction defect claims, focusing on stucco cracking, water intrusion, mold, and warranty disputes, and are accepting inquiries from homeowners in all 50 states. No new class action has been certified from those investigations. If you own a Lennar home with defects, check your purchase agreement for the arbitration and class-waiver language before assuming a class action is available to you, and preserve documentation of the defects, any warranty correspondence, and any repair offers or NDAs before signing anything.
