Lawsuits involving M/I Homes fall into three broad categories: insurance coverage fights tied to construction defects, homeowner claims over warranty and building quality that usually land in arbitration, and development-related disputes with neighbors and local governments. The most legally significant M/I Homes lawsuit is Acuity v. M/I Homes of Chicago, LLC, a 2023 Illinois Supreme Court decision that changed how insurers must respond when contractors are sued for faulty work. For individual buyers, though, the more relevant pattern is that defect claims against the Columbus-based homebuilder are routed to binding arbitration under the purchase agreement, and courts rarely disturb the result.
The Illinois Supreme Court Insurance Ruling
The Acuity case started with a townhome owners’ association in Hanover Park, Illinois, suing M/I Homes of Chicago, LLC over water and moisture intrusion that damaged the interiors of a townhome development. The association alleged breach of contract and breach of the implied warranty of habitability, claiming subcontractors used defective materials, performed faulty work, and failed to comply with building codes.1The Horton Group. Acuity, a Mutual Insurance Company v. M/I Homes of Chi., LLC
M/I Homes was listed as an additional insured on a commercial general liability policy that Acuity had issued to subcontractor H&R Exteriors, Inc. When the association sued, M/I Homes asked Acuity to provide a defense. Acuity refused, arguing that construction defects caused by a contractor’s own faulty work were not an “accident” and therefore not a covered “occurrence,” and that repair and replacement costs did not qualify as “property damage.”2Illinois Courts. Acuity v. M/I Homes of Chicago, LLC, 2023 IL 129087
On November 30, 2023, the Illinois Supreme Court ruled for M/I Homes. It held that unintended and unexpected harm from negligent construction work qualifies as an “accident,” and thus an “occurrence,” under a standard liability policy. It also held that physical injury to the insured’s own work counts as “property damage,” rejecting the requirement that damage must extend to some separate, third-party property to trigger coverage.2Illinois Courts. Acuity v. M/I Homes of Chicago, LLC, 2023 IL 129087 Rehearing was denied on January 22, 2024.
The practical effect: Illinois insurers can no longer refuse to defend a contractor in a construction defect lawsuit simply by arguing that faulty work is not an “accident.” Instead, they must point to specific policy exclusions, and either defend under a reservation of rights or file their own declaratory judgment action. Failing to do so risks being permanently barred from raising coverage defenses under Illinois’ estoppel rule.3Kennedys Law. Acuity v. M/I Homes: Negligent Damage to an Insured’s Work Now Considered Property Damage Caused by an Occurrence Under Illinois Law The ruling expanded coverage availability for homebuilders and general contractors across the state.
What Happens When Homeowners Sue M/I Homes
Homeowners who want to sue M/I Homes over defects usually do not get a courtroom. The purchase agreement requires binding arbitration for “any and all Disputes, including, without limitation, Home Warranty Claims.” A recent Ohio appellate decision shows how that plays out.
In Reynolds v. M/I Homes of Central Ohio, LLC, homeowners Stephen Reynolds and Nicole Hamby had contracted with the builder in October 2021. They later alleged cracks in the poured foundation, buckling wooden floors, tile and grout defects, sagging kitchen cabinets, a missing roof drip edge, and exterior siding discoloration, among other issues. They said M/I Homes marked punch-list items “VOID” and refused to authorize third-party repairs, and they sought more than $53,800 in damages.4Supreme Court of Ohio. Reynolds v. M/I Homes of Cent. Ohio, L.L.C., 2025-Ohio-5818
The case went to the American Arbitration Association. On April 23, 2024, the arbitrator denied every claim, including breach of contract, negligence, violations of the Ohio Home Construction Service Supplies Act, and Magnuson-Moss Warranty Act claims. The homeowners were awarded zero damages and ordered to pay administrative fees and reimburse M/I Homes $800.4Supreme Court of Ohio. Reynolds v. M/I Homes of Cent. Ohio, L.L.C., 2025-Ohio-5818
The homeowners tried to challenge the award in Franklin County Court of Common Pleas. The trial court confirmed the award and granted summary judgment to M/I Homes on April 15, 2025. Ohio’s Tenth District Court of Appeals affirmed on December 30, 2025, finding the arbitrator acted within his authority and the award had a “rational nexus” to the purchase agreement and home warranty.4Supreme Court of Ohio. Reynolds v. M/I Homes of Cent. Ohio, L.L.C., 2025-Ohio-5818
Judicial review of an arbitration award is very narrow. A homeowner who loses at arbitration will find it difficult to get a court to overturn the result, even where the underlying complaints are substantial.
Complaints and Warranty Practices
Formal lawsuits are only part of the picture. M/I Homes is not accredited by the Better Business Bureau and holds a D- rating. As of mid-2026, the BBB shows 80 complaints over the preceding three years, with 24 closed in the most recent 12-month period. Most (61 of 80) involve service or repair issues: poor drainage, shower failures, flooring problems, and disputes over what the warranty covers.5BBB. M/I Homes BBB Profile
Of those 80 complaints, 52 were listed as unresolved and only six were verified as resolved to the consumer’s satisfaction. M/I Homes has consistently directed BBB complainants to its Homebuilders Limited Warranty for formal dispute resolution rather than negotiating through the BBB process. Consumers have reported disputes over earnest money deposits ranging from $3,000 to $58,000, and homeowners have claimed out-of-pocket repair costs in the thousands for issues they say the builder refused to address.6BBB.

The pattern is consistent with what Reynolds shows in court: M/I Homes relies on its contractual framework. Warranty terms define what defects are covered, mandatory arbitration keeps disputes out of court, and limitation-of-remedy provisions restrict homeowners to the builder’s own warranty standards. These tools are common in the homebuilding industry, but the volume of unresolved complaints reflects ongoing friction over how they are applied.
Development and Zoning Disputes
M/I Homes has also litigated over its right to build. In 2025, M/I Homes of Cincinnati, LLC fought a ballot referendum threatening a zoning approval for “Farmstead,” a 239-home development on roughly 120 acres in Batavia Township, Clermont County, Ohio. The Batavia Township Board of Trustees had unanimously approved rezoning in April 2025, but neighboring landowners gathered signatures to put the decision to voters.7Supreme Court of Ohio. State ex rel. M/I Homes of Cincinnati, L.L.C. v. Clermont Cty. Bd. of Elections, 2025-Ohio-4362
M/I Homes asked the Ohio Supreme Court for emergency writs to block the referendum, arguing the petition’s summary was misleading. On September 17, 2025, the court denied the writs. On November 4, 2025, more than 86% of Batavia Township voters rejected the rezoning, ending the Farmstead project.8Cincinnati Enquirer. Batavia Township Votes Down Development
The Chinese Drywall Case
In 2009, M/I Homes was named as a defendant in a federal lawsuit filed by a Tampa, Florida homeowner alleging that Chinese-manufactured drywall installed in the home was toxic, corroded electrical wiring, caused appliances to malfunction, and posed potential long-term health risks.910TV. M/I Homes Named in Toxic Drywall Lawsuit Chinese drywall was a widespread problem for many builders during that period. Available records do not detail the outcome of this specific case.
What This Means for a Homeowner Considering a Claim
If you are dealing with alleged defects in an M/I Homes property, the contract you signed likely sends any dispute to binding arbitration under the Homebuilders Limited Warranty rather than to a courtroom. Read that warranty document carefully, keep detailed records of defects and communications, and understand that the arbitrator’s decision will be extremely difficult to overturn on appeal. Whether courts sitting in your state will require the builder’s insurers to fund a defense in construction defect litigation may depend on rulings like Acuity, which currently apply in Illinois but reflect a coverage question courts nationwide continue to address.
