In Harris v. Liston, 86 Ohio St.3d 203, 1999 Ohio 159, 714 N.E.2d 377, the Ohio Supreme Court held that "tort actions for injury or damage to real property are subject to the four-year statute of limitations set forth in R.C. 2305.09(D)." Id. at 207. The four-year statute of limitations begins to run when damage to the property "is first discovered, or through the exercise of reasonable diligence it should have been discovered." Id. It follows that the Sextons' claims against Rishon and McGill are governed by the four-year statute of limitations set forth in R.C. 2305.09.
