Yes. Foundation issues are a material defect that Ohio law requires sellers to disclose on the Residential Property Disclosure Form. The good news: a documented, engineer-backed repair with a transferable warranty turns that disclosure into evidence the problem was properly fixed.
More detail
Ohio requires most residential sellers to complete the Residential Property Disclosure Form, and known foundation or structural problems are a material defect that must be disclosed on it. That obligation does not go away because you repaired the issue; you disclose both the problem and the repair. This is exactly why how the repair was done matters so much for resale. An undocumented, no-engineer, cash repair leaves a buyer (and their inspector and lender) nervous, because there is no proof the fix was engineered or that it worked. By contrast, a repair that comes with a stamped engineer's report diagnosing the cause, a closeout package documenting the pier depths and load tests or the wall-stabilization spec, before-and-after elevation measurements, and a transferable manufacturer warranty that conveys to the new owner is strong evidence that the problem was correctly diagnosed and permanently addressed. In practice, that documentation often turns the disclosure conversation around: instead of a red flag that triggers a price renegotiation or a failed deal, it becomes a selling point that the home's foundation has been professionally engineered and warranted. Transferability of the warranty is the key detail to confirm before you sign any foundation contract if you might sell within the warranty period; a warranty that conveys to the buyer adds real, marketable value, while one that dies when you sell does not. We provide the full documentation package on every engineered repair specifically so it holds up at the closing table.
