Ohio rent increase law: Chapter 5321 has no cap and one big exception for retaliation

Ohio's Landlord-Tenant Act contains no cap on rent and no section titled rent increase. The closest rule is R.C. 5321.17(B): a landlord or tenant may terminate or fail to renew a month-to-month tenancy by notice given at least 30 days before the periodic rental date. The statute that does name rent increases is R.C. 5321.02, and it forbids using them as retaliation.

How does 5321.17 apply when you want a higher rent?

Division (B) of 5321.17 lets either side "terminate or fail to renew a month-to-month tenancy by notice given the other at least thirty days prior to the periodic rental date." Division (A) gives week-to-week tenancies seven days. The text says nothing about a number to be charged after renewal, so a landlord who wants a higher rent for a month-to-month tenant should give the 30-day notice in writing with the new rent stated, and treat the tenant's continued stay after that date as acceptance of the new amount, or ask the tenant to sign.

Example a made-up owner in Columbus collects $950 on the 1st from a month-to-month tenant. To charge $1,000 starting August 1, the written notice has to be given on or before July 2, which is at least 30 days before the August 1 rental date. A notice given on July 12 would first support September 1.

Is there any limit on the amount?

Not in Chapter 5321 as read on the Ohio Revised Code site. Division (C) of R.C. 5321.02 confirms the opposite of a cap in one respect: nothing in the retaliation division prohibits "a landlord from increasing the rent to reflect the cost of improvements installed by the landlord in or about the premises or to reflect an increase in other costs of operation of the premises." I did not find a state rule preempting local rent control in the chapter, so confirm with your city before you set the number in an unusual market.

When does a raise become retaliation?

R.C. 5321.02(A) says a landlord may not retaliate "by increasing the tenant's rent, decreasing services that are due to the tenant, or bringing or threatening to bring an action for possession" because the tenant:

  • complained to a government agency about a building, housing, health or safety code violation that materially affects health and safety;
  • complained to the landlord about a violation of R.C. 5321.04, the landlord's duties; or
  • joined with other tenants to deal collectively with the landlord on the terms of a rental agreement.

Division (B) lets the tenant use the retaliatory act as a defense to a possession action, recover possession, or terminate the rental agreement, and recover actual damages together with reasonable attorneys' fees. Section 5321.03 sets out circumstances in which the landlord may act despite 5321.02; check it for the case at hand.

What if there is a written lease?

The Act does not fix the length or the price of a lease, so the lease decides. For a fixed term, the rent in the lease is what the tenant owes until the term ends, and a different rent needs the tenant's agreement. Put the new price and renewal date in a renewal offer. A lease with automatic renewal clauses should state what happens to the rent in each renewal period.

What to check before you send an Ohio notice

  1. Find the tenancy type: fixed term, month-to-month or week-to-week.
  2. For month-to-month, work back 30 days from the rental date the new rent starts.
  3. Look for a recent code complaint or repair request, and be ready to explain the raise by costs or a market-wide schedule.
  4. Put the old rent, the new rent and the start date in writing, and keep proof of the date given.
