Cincinnati Landlord Heating Requirements: What Ohio Law Says

Ohio law requires Cincinnati landlords to supply running water, reasonable amounts of hot water, and reasonable heat at all times, and to keep any heating equipment they supply in good and safe working order. The state doesn’t put a number on “reasonable.” The City of Cincinnati does for units where tenants don’t control their own heat: 70 degrees inside once the outdoor temperature has stayed below 60 degrees for 24 hours straight. If a tenant has no heat right now, skip to our landlord guide for when a tenant has no heat. This post is about the law itself.

A note before you read further: we are heating contractors, not lawyers. This is a plain-language summary, not legal advice. Confirm anything you plan to act on with a landlord-tenant attorney.

What Ohio Law Requires Cincinnati Landlords to Provide for Heat

The core rule is Ohio Revised Code 5321.04, the list of landlord obligations. Three parts of it cover heat:

Fit and habitable. Landlords must make all repairs and do whatever is reasonably necessary to keep the premises fit and habitable, and comply with building, housing, health, and safety codes that materially affect health and safety.

Equipment in good and safe working order. Landlords must maintain all electrical, plumbing, sanitary, heating, ventilating, and air conditioning fixtures and appliances they supply or are required to supply.

Reasonable heat at all times. Landlords must supply running water, reasonable amounts of hot water, and reasonable heat at all times.

The Exception for Tenant-Controlled Heat

The heat duty has two exceptions. It doesn’t apply where the building isn’t required by law to be equipped for heat, or where the unit is built so the heat comes from an installation within the tenant’s exclusive control, supplied by a direct public utility connection. In plain terms: if the unit has its own furnace on its own gas meter in the tenant’s name, the tenant runs and pays for the heat.

That exception covers supplying the heat, not maintaining the furnace. The separate duty to keep supplied heating equipment in good and safe working order still applies. If the furnace in a tenant-metered unit breaks, the repair is still on you.

What Ohio Law Does Not Say: No Statewide Minimum Temperature

Ohio has no statewide minimum indoor temperature for rentals. The statute says “reasonable heat” and stops there. It also sets no heating season.

Cities fill that gap in their own codes, and the numbers differ. If you own rentals in more than one Ohio city, read each city’s code.

Cincinnati’s 70-Degree Rule for Units Without Tenant-Controlled Heat

The Cincinnati Health Department enforces the rule under a Board of Health regulation, and tenants can report a problem through the city’s 311 no-heat request. Once the outdoor temperature stays below 60 degrees for 24 consecutive hours, the inside of the unit must be 70 degrees or warmer. The rule applies to units where tenants don’t control their own heat, which in practice means apartments on a shared boiler or a central system with one thermostat for the building.

Fines and Enforcement

Tenants report through 311 or the Health Department’s Healthy Homes line. An inspector visits and measures the temperature. If it is below 70, the owner is ordered to fix it. The fines are $300 for the first day and $750 for each additional day without adequate heat. A landlord who ignores a Board of Health order can be prosecuted, with up to 180 days in jail and a fine of up to $1,000.

Temporary Heat While Repairs Happen

While repairs are under way, the city allows two stopgaps: space heaters that keep the living space at 70 degrees or more, or temporary housing such as a short hotel stay. The repair still has to happen.

Who Provides the Heating Equipment and Who Pays the Gas Bill in Cincinnati

The equipment is the owner’s job. Section 1117-35 of the Cincinnati Building Code (the housing code chapter) requires the owner or operator of a dwelling to provide heating facilities capable of safely heating all habitable rooms and toilet rooms to 70 degrees, measured three feet above the floor at the center of the room, when it is 0 degrees outside. The equipment must be installed in an approved manner and kept in good working condition.

The same section gives the owner a defense if the tenant agreed in writing to provide the heating facilities. It also says no landlord may evict a tenant, or refuse to rent to one, solely because the tenant won’t agree to that. So a lease can shift the equipment to the tenant only with written agreement, and you can’t make that agreement a condition of renting.

The utility bill is whatever the lease says. Ohio law doesn’t say whether landlord or tenant pays for gas or electricity. The lease decides. What the law does say is that when the heat comes from the tenant’s own equipment on the tenant’s own utility account, the landlord isn’t the one supplying heat. When the building runs one boiler on one meter in the owner’s name, the owner is supplying heat and the 70-degree rule applies.

What Tenants Can Do Under ORC 5321.07

When a landlord doesn’t meet the 5321.04 duties, Ohio Revised Code 5321.07 gives tenants a set of remedies. They follow a fixed order.

Step 1: Written Notice

The tenant gives the landlord written notice describing the problem. It goes to the person or place where rent is normally paid. The same route opens when a government agency has found a code violation that could materially affect health and safety.

Step 2: A Reasonable Time, 30 Days at Most

The landlord then has a reasonable time to fix the condition, judged by how severe it is and how long the repair takes, or 30 days, whichever is sooner. Thirty days is the ceiling, not a grace period. A broken furnace in January is a severe condition, and a reasonable time for it is likely to be much shorter. Ask your attorney how local courts read that.

Step 3: The Remedies

If the landlord doesn’t fix it in time and the tenant is current on rent, the tenant may do one of three things:

Deposit rent with the court clerk. The tenant pays all rent due, and all rent that comes due after, to the clerk of the municipal or county court for the area where the rental is, instead of to the landlord.

Ask the court for an order. The tenant can apply for an order directing the landlord to fix the condition, and can ask the court to reduce the rent until it is fixed or to use the deposited rent to pay for the repair.

End the lease. The tenant can terminate the rental agreement.

The Three-Unit Exception

Section 5321.07 doesn’t apply to a landlord whose rental agreements cover three or fewer units, if the landlord gives notice of that fact in a written lease (or, for an oral tenancy, in writing at move-in). That exception covers only these remedies. The 5321.04 duty to supply heat and maintain the equipment still applies, and so does Cincinnati’s 70-degree rule.

Shutting Off Heat to Force a Tenant Out Is Illegal in Ohio

Ohio Revised Code 5321.15 bars a landlord from starting any act, including terminating utilities or services, locking a tenant out, or threatening an unlawful act, to recover possession of a rental, other than through the court process the Revised Code sets out. That includes tenants whose right to stay has ended. They still have to be removed through an eviction case, not by turning off the gas.

A landlord who breaks this rule is liable in a civil case for all damages the tenant suffered, plus reasonable attorney’s fees. In Cincinnati, a shut-off in a shared-heat unit also starts the Health Department’s daily fines.

Northern Kentucky Rentals Follow Kentucky Law

If you own rentals in Covington, Newport, or elsewhere across the river, none of the Ohio sections above apply. Kentucky has its own landlord-tenant statute, and it only takes effect in cities and counties that have adopted it, so the rules can change from one Northern Kentucky city to the next. Where it has been adopted, KRS 383.640 covers heat: if a landlord willfully fails to supply it, a tenant who gives written notice can buy reasonable heat and deduct the cost from rent, recover damages, or move to substitute housing and stop paying rent for that period. Check the city’s ordinances and talk to a Kentucky attorney before you rely on anything here for a Kentucky property. The same goes for rentals in Southeast Indiana.

How Cincinnati Landlords Stay Within the Heat Rules

Most heat violations are furnaces and boilers that fail on the first cold weekend with no one booked to look at them. The law gives you little room once that happens, so the work is in the fall.

Here is our view: in a shared-heat building, the Cincinnati fine schedule matters more than the state statute. At $300 for the first day and $750 for each day after, a boiler that waits three days for a part costs $1,800 in fines before the repair bill. A fall tune-up, a spare-parts check on older equipment, and a plan for space heaters cost much less than that.

Service every system before November. Our pre-winter HVAC checklist for rental properties covers what to check in each unit.

Keep dated records. A record of each tune-up and repair shows you kept the equipment in good and safe working order, which is the 5321.04 standard. A preventive HVAC maintenance plan for rentals builds that record for you.

Spell out heat in the lease. Say who pays which utility, who changes filters, and how the tenant reports a heating problem. If you want the tenant to provide heating equipment, get it in writing and don’t make it a condition of renting.

Respond to written notice the same day. Book furnace repair or boiler service right away, and keep proof of when you called.

When You Don’t Need a Heating Contractor

Not every heat complaint needs us. Legal questions, such as whether your lease qualifies for the three-unit exception or how to answer a notice from the court clerk, go to a landlord-tenant attorney.

If the tenant controls the heat and the gas is off because the tenant’s utility account was shut off for nonpayment, there is nothing to repair. That is between the tenant and the utility. And plenty of “no heat” calls end with a thermostat set to cool, dead thermostat batteries, a furnace switch flipped off, or a filter so clogged the furnace shut itself down. Walk the tenant through those first. If the heat comes back and stays on, you don’t need a visit.

Call a technician when the equipment itself has failed, when there is any gas smell or carbon monoxide alarm, or when a Cincinnati shared-heat unit is below 70 degrees and the cause isn’t obvious.
