Landlord retaliation law in Ohio: what R.C. 5321.02 bars and what the tenant can do

What are the three protected acts?

Division (A) is subject to section 5321.03, which lists situations where the landlord may act. Within it, the protected acts are that the tenant complained to an appropriate governmental agency of a violation of a building, housing, health or safety code applicable to the premises that materially affects health and safety; that the tenant complained to the landlord of a violation of section 5321.04, the landlord's list of obligations; or that the tenant joined with other tenants to negotiate or deal collectively with the landlord on the terms and conditions of a rental agreement.

Why does the word "because" matter?

Division (A) bars the three landlord acts because of the tenant's protected act. Unlike statutes in Montana, Kentucky or D.C., it does not set a window or create a presumption, so the question in court is what actually caused your decision. The best evidence is a record made before the complaint: rent increase letters tied to lease renewal dates, a ledger showing a missed payment, a written notice about a lease violation dated when you saw the violation.

Division (C) says a landlord may still increase rent to reflect the cost of improvements installed in or about the premises or an increase in other costs of operating the premises. Keep invoices that show the cost increase, and apply the increase across comparable units.

Example a made-up tenant complains to the city about a code violation on Monday, November 2, 2026. The landlord's lease renewal letters have gone out every year on the first Monday of November, and this year's letter, dated Monday, November 2, 2026 and sent to every tenant, raises all rents by the same amount because of a documented tax increase. The pre-set schedule and the building-wide increase support a legitimate reason. A rent increase sent only to this tenant on Friday, November 6 would be harder to defend.

What can an Ohio tenant do if the landlord retaliates?

Division (B) lets the tenant use the landlord's retaliation as a defense to an action to recover possession, recover possession of the premises, or terminate the rental agreement. In addition, the tenant may recover actual damages and reasonable attorneys' fees. Fee shifting is the part that surprises landlords, so a weak retaliation fight can cost more than the rent at stake.

• Date and keep every rent letter, and send them on a regular schedule.
• Keep the ledger and notices for nonpayment and the lease for violations.
• Respond in writing to complaints about your duties and log the repair dates.
• Do not threaten an action for possession in a reply to a complaint.

Read section 5321.03 as well, since division (A) is subject to it. This post describes only the text of 5321.02, and a landlord with a real reason should still write it down on the day it arises.

Where does DoorKeeping fit?

DoorKeeping keeps the maintenance requests, tenant messages, rent ledger and notices for each unit in one timeline, so the date of a complaint and the date of your next action sit side by side. That record is what you show a judge. You decide and act yourself. This is general information, not legal advice: check the current statute, and ask a local attorney if a tenant raises retaliation.
