State pet-deposit treatment, federal Fair Housing Act assistance-animal rules, and what Ohio landlords can and cannot ask.
In Ohio, the pet policy in your lease and the law that governs assistance animals are two different things. Ordinary pets are a matter of private contract: you can ban them, cap their number, or charge pet rent and pet deposits, all through R.C. Chapter 5321, Ohio's landlord-tenant statute. Service animals and emotional support animals are not pets in the eyes of the law, and no-pet clauses do not apply to them.
Assistance animals are protected by two layers of law. The federal Fair Housing Act requires you to make reasonable accommodations for a tenant's disability-related animal, and Ohio's own fair housing law, R.C. 4112.02(H), makes it an unlawful discriminatory practice to refuse a reasonable accommodation needed for a person with a disability to use and enjoy a dwelling. Ohio actually goes further than federal law in one respect: the state's "animal assistant" definition in Ohio Administrative Code 4112-5-02 is broad enough to cover animals of any species, not just the dogs the ADA recognizes as service animals.
The practical upshot for a landlord: you can run a strict pet program on ordinary pets, but you must treat a properly documented service or support animal as an accommodation, not a pet, and you cannot charge it pet fees. Getting the distinction wrong is what generates complaints to the Ohio Civil Rights Commission and HUD.
Ohio has no statutory cap on the security deposit or pet deposit. Ohio Rev. Code § 5321.16 governs return procedures but sets no maximum.
A pet is any animal kept for companionship that is not tied to a disability. For pets, your lease controls. Under R.C. Chapter 5321 you may prohibit pets entirely, restrict breeds or weight, require a pet addendum, and charge pet rent or a pet deposit. Nothing in Ohio law forces you to allow pets.
A service animal, under the federal ADA, is a dog (and in limited cases a miniature horse) individually trained to perform work or tasks for a person with a disability, such as guiding someone who is blind or alerting to a seizure. Ohio's R.C. 955.43 separately guarantees assistance-dog handlers full and equal access to public accommodations at no extra charge.
An emotional support animal (ESA) provides comfort that eases the symptoms of a mental or emotional disability but is not trained to perform a specific task. ESAs get no public-access rights, but in housing the Fair Housing Act and R.C. 4112.02 treat them the same as service animals: they are assistance animals entitled to reasonable accommodation. Ohio's broad animal assistant standard under OAC 4112-5-02 means the species is not, by itself, a valid reason to refuse.
This is the rule landlords most often get wrong. Because a service or support animal is an accommodation and not a pet, you may not charge a pet deposit, pet rent, or any pet surcharge for it, even if every other tenant with an ordinary pet pays those fees. Requiring the animal to be removed, or conditioning approval on an extra payment, is a fair housing violation under R.C. 4112.02(H).
What you keep is the right to recover for real harm. The tenant remains fully liable for actual damage the animal causes to the unit, and you can deduct that from the ordinary security deposit or pursue it like any other damage claim under R.C. Chapter 5321. You simply cannot front-load a charge as a condition of allowing the animal. You may also hold the animal's owner to the same conduct standards as anyone else: an assistance animal that is out of control, not housebroken, or a direct threat can still be grounds for action.
When a disability and the need for the animal are not obvious, you may request reliable documentation that the tenant has a disability and that the animal is needed because of it. In practice this is a letter from a physician, psychologist, social worker, or other healthcare provider stating a disability-related need. You are entitled to that verification, and you may deny a request backed only by an obviously purchased online certificate with no genuine provider relationship.
What you may not do: ask for the tenant's specific diagnosis or medical records, demand proof of the animal's training or certification, require the animal to wear a vest or ID, or insist on a particular breed. There is no official Ohio or federal registry for assistance animals, so any request for a registration number is improper. When the disability and connection to the animal are readily apparent, you should not ask for documentation at all.
Fair housing law does not make assistance animals untouchable. You may deny or revoke an accommodation when the specific animal poses a direct threat to the health or safety of others that cannot be reduced by another reasonable accommodation, or when it would cause substantial physical damage to property. The assessment must be individualized and based on the animal's actual conduct, not on breed stereotypes or fear.
You may also deny a request that imposes an undue financial or administrative burden or would fundamentally alter the nature of your operation, though that is a high bar rarely met for a single animal in a residential rental. And an assistance animal gets no special immunity from lease enforcement: repeated noise, aggression, or failure to clean up after the animal can support a warning and, if unresolved, an eviction under R.C. Chapter 5321, just as it would for any tenant.
Ohio has cracked down on fake assistance animals. Under R.C. 955.43, as amended by House Bill 121, a person who knowingly misrepresents an animal as a service animal or assistance animal commits a minor misdemeanor. Under R.C. 2929.28, a minor misdemeanor carries a maximum fine of $150 and no jail time. This gives landlords a real, if modest, backstop against abuse, though the safer path is almost always to request proper documentation rather than to pursue charges.
If a tenant believes you denied a lawful accommodation, they can file with the Ohio Civil Rights Commission at 888-278-7101 or with HUD's Office of Fair Housing and Equal Opportunity at 800-669-9777. Both agencies impose a one-year deadline from the alleged violation. Disability Rights Ohio (800-292-9181) also assists tenants. Because these complaints can carry damages and civil penalties, document every accommodation request and your response in writing.
The most common mistake in Ohio ESA cases is responding with a flat denial, "no pets means no pets", instead of engaging in the interactive process. The interactive process is itself a substantive duty. A landlord who refuses to consider the request, demands more documentation than HUD permits, or imposes a pet fee on an accepted assistance animal will lose at HUD even if the underlying accommodation could have been reasonably denied on its merits.

No. A service animal or ESA is treated as a reasonable accommodation, not a pet, so you cannot charge a pet deposit, pet rent, or pet surcharge for it under R.C. 4112.02(H) and the federal Fair Housing Act. The tenant still remains liable for any actual damage the animal causes, which you can recover through the ordinary security deposit.
No. No-pet clauses cover ordinary pets only. Because service animals and ESAs are assistance animals, a no-pet policy cannot be used to exclude a properly documented one. You can, however, enforce a no-pet policy against animals kept purely for companionship with no disability-related need.
When the disability or need is not obvious, you may ask for reliable documentation, typically a letter from a healthcare provider, confirming the tenant has a disability and needs the animal because of it. You may not ask for the specific diagnosis, medical records, proof of training, or a registration number, and there is no official Ohio assistance-animal registry.
Yes, in limited cases. You may deny or revoke the accommodation if the specific animal is a direct threat to others' safety or would cause substantial property damage that cannot be otherwise mitigated, based on the animal's actual conduct rather than its breed. Ongoing lease violations tied to the animal can also support eviction under R.C. Chapter 5321.
Yes. Under R.C. 955.43, amended by House Bill 121, knowingly misrepresenting an animal as a service or assistance animal is a minor misdemeanor. Ohio's minor-misdemeanor penalty under R.C. 2929.28 is a fine of up to $150 with no jail time.
In housing, yes. While the federal ADA generally limits service animals to dogs, Ohio's 'animal assistant' definition in OAC 4112-5-02 is broad enough to cover animals of other species that aid a person with a disability. So an assistance animal in a rental cannot be refused simply because it is not a dog.
