Eviction defenses, security deposits, and habitability.
Ohio courts apply both the U.S. Constitution and the Ohio Constitution to landlord–tenant disputes claims. When state protections are broader than federal ones, Ohio judges follow the state rule. When they are equal or narrower, federal precedent controls under the Supremacy Clause.
Federal cases governing landlord–tenant disputes include controlling U.S. Supreme Court decisions and binding precedent from the federal circuit covering Ohio. Civil remedies most often proceed under 42 U.S.C. § 1983, with defenses including qualified immunity.
