TL;DR
Most jurisdictions with heating laws require landlords to provide heat during a set season, commonly October 1 through May 31, and to maintain a minimum indoor temperature, often 68°F during the day and 65°F at night. Exact dates, temperatures, and enforcement agencies vary by city and state, so always confirm with your local housing or code office.
When is a landlord legally required to turn on the heat?
A landlord has to provide working heat whenever local law sets a heating season and your unit falls inside it. There's no single national rule. Instead, states, counties, and cities each set their own heating season dates and minimum temperatures, usually inside a housing code, sanitary code, or health code section. New York City is the most-cited example because its rule is specific and well enforced. Under the city's Housing Maintenance Code, during "Heat Season" (October 1 through May 31), building owners must maintain an indoor temperature of at least 68°F between 6 a.m. and 10 p.m. whenever the outdoor temperature falls below 55°F, and at least 62°F overnight from 10 p.m. to 6 a.m. regardless of outdoor temperature [1]. Chicago's Municipal Code sets a similar but distinct standard: from September 15 through June 1, residential building owners must maintain at least 68°F during the day (8:30 a.m. to 10:30 p.m.) and 66°F overnight [2]. Many other cities and states borrow this same structure (a defined season plus a daytime and nighttime minimum) but change the dates and numbers. Some states leave heat entirely to local housing codes, meaning there's no statewide rule at all unless your city or county has adopted one. If you own units in more than one city, do not assume the rules match. Pull the actual code section for each city where you operate, because a fine in one city (New York's civil penalties can run from $250 to $1,250 per violation per day for repeat offenses [1]) can look completely different from the penalty structure next door. If you're prepping a unit for licensing or inspection season across multiple cities, our City Rental License & Inspection Prep Packet is a $79 one-time tool built to help you track city-specific requirements like heat season dates in one place instead of hunting through code books city by city.
What is the minimum temperature a landlord must provide?
The minimum indoor temperature almost always splits into a daytime number and a lower nighttime number, and both only apply during the defined heating season. New York City requires 68°F indoors from 6 a.m. to 10 p.m. when it's below 55°F outside, dropping to a 62°F minimum overnight [1]. Chicago requires 68°F during the day and 66°F at night, with its own separate season dates (September 15 to June 1) [2]. Some cities use a flat 65°F standard with no time-of-day split; others tie the requirement to outdoor temperature thresholds rather than a fixed calendar. A few state landlord-tenant statutes describe the duty in general terms, such as requiring landlords to supply heat "as required to maintain a temperature reasonably suited for human habitation," without spelling out an exact number, which pushes the real detail down to a local health or housing code. The unit for temperature and the enforcement window matter as much as the number itself. A code that says 68°F "during the day" is meaningless to a tenant filing a complaint unless the code also defines what hours count as day and what the outdoor trigger temperature is. When you're reading your city's ordinance, look for three things specifically: the season start and end date, the daytime minimum with its hours, and the nighttime minimum with its hours (or the flat minimum if there's no split).
What happens if a landlord doesn't turn on the heat?
Consequences range from a code inspection and repair order to steep daily fines, rent withholding, or a tenant moving to emergency repair remedies, depending on the city and how quickly the landlord responds. In most heating-season cities, the process starts with a tenant complaint to the housing or code enforcement department. An inspector visits, measures indoor temperature, and if it's below the legal minimum, issues a violation notice with a repair deadline. New York City's civil penalty schedule runs $250 to $1,250 per violation per day depending on how many prior violations the building has [1]. Cities without a heat-specific ordinance may still cite you under a general "unsafe and unsanitary conditions" or "warranty of habitability" provision, which most states recognize even without a numeric temperature standard. Tenants often have their own remedies that don't require the city at all: rent withholding into escrow, "repair and deduct" statutes that let a tenant hire a repair and subtract the cost from rent (subject to caps and notice requirements that vary by state), or in the worst cases, constructive eviction claims if the unit becomes uninhabitable. A landlord who ignores a documented heat outage for days, especially in freezing weather, is exposed on multiple fronts at once: code fines, a habitability claim, and potentially a rent abatement ordered by a judge. The cheapest move, every time, is fixing the furnace fast and documenting the timeline, not fighting the notice.
Does every city have a heat law, or just some?
No. Heat requirements are set at the state or local level in the U.S., and coverage is patchy: some states have no statewide heating law at all, leaving the rule entirely to whichever cities or counties choose to adopt one. States with strong tenant-protection traditions (New York, Illinois, Massachusetts, and several others) tend to have either a statewide rule or a set of city ordinances that fill the gap. Rural areas and smaller cities in other states may have nothing more specific than a general habitability statute that says heat has to be "adequate" without a number attached. That ambiguity cuts both ways: it can be harder for a tenant to win a fast enforcement action, but it also means a landlord can't point to a specific safe-harbor temperature and claim compliance. If you own in a mandatory rental-licensing city, check whether the heat requirement lives inside your rental license or inspection checklist. Cities that require a rental license often bundle habitability standards, including heat, into the same inspection that checks smoke detectors, egress windows, and electrical safety. Missing the heat standard on a licensing inspection can delay or block your license renewal entirely, separate from any tenant complaint. Related reading on what these inspections actually check: what a landlord inspection covers.
What can a landlord look at during an inspection?
What can a landlord look at during an inspection?
A rental inspection, whether it's tied to licensing, a tenant complaint, or a routine city walk-through, typically checks life-safety and habitability items: working smoke and carbon monoxide detectors, secure locks, functioning heat, hot water, electrical safety, structural soundness, and freedom from pest infestation. Inspectors are generally not there to judge cleanliness, décor, or how you keep your own belongings; they're checking code compliance items tied to specific statute or ordinance sections. Common inspection checklist items across mandatory-licensing cities include: heating system function and (where applicable) measured indoor temperature, smoke and CO detector presence and function, secured or code-compliant egress windows and doors, absence of exposed wiring or overloaded circuits, functioning plumbing without active leaks, and pest or mold conditions. Some cities add exterior items: peeling exterior paint (a lead hazard concern in pre-1978 housing under federal lead paint disclosure rules [3]), broken steps or railings, and trash or debris in yards. What a landlord (or their inspector) can look at inside a tenant's unit is limited by notice requirements, covered in the next section, and by the scope of the inspection itself. A routine habitability inspection is not a general search; it's confined to the systems and conditions the ordinance authorizes someone to check. If you're building out a pre-inspection checklist for your own unit, our guide on tenant rights during landlord inspections covers the tenant side of that same event.
Who is responsible for a rental property walk-through inspection in California?
In California, the landlord is responsible for arranging the walk-through inspection and giving proper notice, but state law also gives the tenant the right to be present. Under California Civil Code Section 1950.5, when a landlord plans to withhold any part of a security deposit at move-out, the tenant has the right to request an initial inspection before the tenancy ends, giving the tenant a chance to fix deficiencies and avoid deductions [4]. The statute requires the landlord to give the tenant reasonable notice of the initial inspection, at least 48 hours in most cases, and to provide an itemized statement of any needed repairs or cleaning identified during that walk-through, so the tenant has an opportunity to address them before the final move-out inspection [4]. This pre-move-out inspection is separate from routine mid-tenancy inspections, which fall under California's general entry notice rules (Civil Code Section 1954), requiring at least 24 hours' written notice for non-emergency entry [5]. Rental licensing walk-throughs conducted by a city (separate from the landlord-tenant deposit inspection) are a different animal entirely: the city inspector, not the landlord, drives that process, and notice requirements come from the local ordinance rather than the Civil Code. If your California city requires a rental license, check that city's specific inspection notice period; it often differs from the 24-hour entry standard.
How much notice does a landlord have to give before entering?
Notice periods for landlord entry are set state by state, and 24 hours is the most common baseline, though it's not universal. California requires "reasonable notice," which the statute defines as presumptively 24 hours' written notice for most non-emergency entries [5]. Many other states use similar 24-hour or 24-to-48-hour windows, but a few states set different defaults, and some don't specify a number at all, just requiring "reasonable" notice, which leaves room for dispute. Emergency entry is the standard exception across nearly every state: if there's a fire, flood, gas leak, or another situation threatening life or property, a landlord can enter without advance notice. Routine repairs, showing the unit to prospective tenants or buyers, and scheduled inspections generally do require advance written notice under the applicable state statute. For a heat-related repair specifically, most landlords give notice and coordinate a repair time with the tenant anyway, both because it's good practice and because a broken furnace in winter often qualifies as close to urgent enough that tenants rarely object to a same-day fix. But if you need to force entry against a tenant's wishes for a non-emergency heat repair, follow your state's statutory notice period exactly, in writing, because skipping that step can turn a simple repair into a wrongful-entry claim.
What is landlording, and what is a landlord?
A landlord is the owner (or the owner's authorized agent) who rents real property, typically a house, apartment, or room, to a tenant in exchange for rent, under either a written lease or an oral/month-to-month agreement. "Landlording" is the informal term for the ongoing work of managing that relationship: collecting rent, maintaining the property, handling repairs, following local licensing and inspection rules, and managing the legal side of tenant turnover. In most states, a landlord's core legal duties come from a mix of common law (the implied warranty of habitability, recognized in some form in the vast majority of U.S. states) and specific statutes covering security deposits, entry notice, eviction procedure, and, as covered above, heat and other utilities. A landlord isn't required to have a special professional license just to rent out a property in most of the U.S., but a growing number of cities require a rental registration or rental license specifically, separate from any state real estate license. Small landlords, meaning individuals who own somewhere between one and ten units, make up a real share of the U.S. rental market: the U.S. Census Bureau's Rental Housing Finance Survey found that individual investors owned roughly 41% of all rental units nationally as of the most recent survey wave [6]. That's a lot of people who are, functionally, running a small business without necessarily thinking of it that way, which is exactly why licensing and inspection rules catch people off guard.
How do you become a landlord, and how do you actually do it well?
Becoming a landlord legally requires three things at minimum: owning (or having authority to rent) the property, complying with your city or county's rental registration or licensing rules if they apply, and following your state's landlord-tenant statute for leases, deposits, entry, and eviction. There's no license exam required in most of the country, but skipping the local registration step is one of the most common first-year mistakes. A practical starting checklist looks like this: confirm whether your city requires a rental license or registration (search "[your city] rental registration" or check with the city's housing or code enforcement department directly), get a lease that matches your state's required disclosures (lead paint disclosure for pre-1978 units is a federal requirement under 42 U.S.C. § 4852d [3]), set up a compliant security deposit process, and build a maintenance response plan before you have your first tenant, not after. Heat compliance belongs on that checklist from day one if you're in a heating-season jurisdiction. New landlords often don't realize their furnace age or condition until the first cold snap produces a tenant complaint, and by then you're reacting under pressure instead of planning. Get the furnace serviced and confirm it can hit your city's minimum temperature before the heating season starts, not after a tenant calls code enforcement. For city-specific licensing steps, see our related guide on landlord licensing basics.
What rights do tenants have without a written lease?
A tenant without a written lease still has full legal protection under state landlord-tenant law; an oral or month-to-month tenancy is a real, legally recognized tenancy, not a lesser or unprotected one. The absence of a written lease mainly affects term length and how notice to end the tenancy works, not the underlying rights. Without a written lease specifying a fixed term, most states treat the arrangement as a month-to-month tenancy, meaning either party can end it with proper notice, commonly 30 days, though some states require more for longer-term tenants. All of the core statutory protections still apply regardless of lease status: the implied warranty of habitability, protection from illegal lockouts and self-help eviction, security deposit rules if a deposit was collected, and, where applicable, the heating and minimum temperature standards covered earlier in this article. What a tenant without a lease does lose is the certainty a written agreement provides: a fixed rent amount for a defined term, specific maintenance responsibilities spelled out, and clear proof of the terms both sides agreed to. Disputes over an oral agreement often come down to one person's word against another's, which is exactly why most landlords, even ones renting to family or friends, are better off putting terms in writing regardless of what state law technically requires.
Why do landlords require renters insurance?
Landlords require renters insurance mainly to shift liability for a tenant's personal property loss and personal liability claims away from the landlord's own policy, and to reduce disputes after a fire, water damage, or theft. A landlord's own property insurance covers the building structure; it typically does not cover a tenant's furniture, electronics, or clothing, and it may not fully cover a tenant's liability if the tenant's guest is injured in the unit. Requiring renters insurance as a lease condition is legal in nearly every state, and many landlords set a minimum liability coverage amount, commonly in the $100,000 to $300,000 range, as a lease requirement. This is a private contract term, not a government mandate; a handful of cities have discussed requiring it, but for the vast majority of the country it's the landlord, not the law, requiring the policy. From a landlord's risk-management view, renters insurance also reduces the odds that a tenant tries to hold the landlord financially responsible for the tenant's own property loss after an incident like a heat-related pipe burst or fire, since the tenant's insurer typically becomes the first line of financial responsibility for the tenant's belongings instead of the landlord's insurer or the landlord personally.
What can a landlord not do in Ohio?
Ohio landlord-tenant law, codified mainly in Ohio Revised Code Chapter 5321, prohibits several specific landlord actions. A landlord cannot shut off utilities, change the locks, or remove a tenant's belongings to force the tenant out; Ohio law requires landlords to use the formal court eviction process (called a "forcible entry and detainer" action) rather than self-help remedies [7]. Ohio law also requires landlords to maintain the premises in a habitable condition, including keeping "all electrical, plumbing, sanitary, heating, ventilating, and air-conditioning fixtures and appliances" in good and safe working order under Ohio Revised Code § 5321.04 [7]. That statutory duty is the legal backbone for heat-related repair obligations in Ohio, even in cities that don't have their own separate numeric heat ordinance. A landlord who fails to make repairs after receiving written notice from the tenant can be sued for damages, and in some cases the tenant can deposit rent with the court (a process sometimes called an escrow or rent deposit remedy) rather than paying the landlord directly, under the procedures set out in Ohio Revised Code § 5321.07 [7]. Ohio law also prohibits retaliatory conduct: a landlord cannot raise rent, decrease services, or start eviction proceedings specifically because a tenant complained to a housing authority or joined a tenant organization, under the retaliation protections built into ORC Chapter 5321 [7]. For Ohio landlords in cities with their own rental registration or inspection program layered on top of state law, both sets of rules apply at the same time, and the local ordinance is often stricter, not looser, than the state floor.
Frequently asked questions
When is a landlord required to turn on the heat?
It depends on your city or state's heating season. New York City's heat season runs October 1 through May 31 [1]; Chicago's runs September 15 through June 1 [2]. Outside those seasons, most jurisdictions don't set a numeric heat requirement, though a general habitability standard can still apply if a unit becomes unsafe.
What is the lowest legal temperature a landlord can allow indoors?
It varies by city. New York City requires 68°F during the day (when it's below 55°F outside) and 62°F overnight during heat season [1]. Chicago requires 68°F during the day and 66°F at night [2]. Many other cities set their own numbers between roughly 65°F and 68°F, so check your specific city's code.
How to become a landlord?
Buy or gain legal authority over rental property, check whether your city requires rental registration or licensing, get a lease compliant with your state's disclosure rules (including federal lead paint disclosure for pre-1978 units [4]), and follow your state's landlord-tenant statute for deposits, entry notice, and eviction procedure.
Who is responsible for a rental property walk-through inspection in California?
The landlord arranges and conducts the walk-through, but California Civil Code § 1950.5 gives tenants the right to request an initial inspection before move-out with at least reasonable notice, so they can fix issues before final deposit deductions are made [5].
What is landlording?
Landlording is the ongoing work of owning and managing rental property: collecting rent, handling maintenance and repairs, following local licensing and inspection rules, managing leases, and complying with state landlord-tenant law on deposits, entry, and eviction.
What is a landlord?
A landlord is the property owner, or an authorized agent acting for the owner, who rents real property to a tenant in exchange for rent under a lease or rental agreement, written or oral.
What rights do tenants have without a lease?
A tenant without a written lease still has full protection under state landlord-tenant law, including habitability rights, protection from illegal lockouts, and security deposit rules if applicable. The tenancy is usually treated as month-to-month, meaning either side can end it with statutory notice, often 30 days.
How to be a landlord (day-to-day)?
Respond to maintenance requests promptly, especially heat and safety issues, keep the unit compliant with your city's licensing and inspection rules, give proper notice before entering (commonly 24 hours), document everything in writing, and follow your state's eviction procedure rather than any self-help removal.
Why do landlords require renters insurance?
To shift liability for a tenant's personal property loss and personal injury claims away from the landlord's own policy. A landlord's property insurance generally doesn't cover a tenant's belongings, so requiring renters insurance reduces disputes and financial exposure after fires, floods, or theft.
How much notice does a landlord have to give before entering?
Most states require at least 24 hours' written notice for non-emergency entry; California specifically presumes 24 hours is reasonable under Civil Code § 1954 [6]. Emergencies (fire, gas leak, flooding) are the standard exception allowing entry without advance notice.
What can a landlord look at during an inspection?
Inspections typically check life-safety and habitability items: smoke and CO detectors, heating function, electrical safety, plumbing leaks, secure locks and egress, and pest or mold conditions. Inspectors generally aren't evaluating cleanliness or personal belongings, just code-compliance items tied to specific ordinance sections.
What can a landlord not do in Ohio?
Ohio landlords cannot shut off utilities, change locks, or remove belongings to force a tenant out; they must use the court eviction process. They also must keep heating, plumbing, and electrical systems in good working order under Ohio Revised Code § 5321.04, and cannot retaliate against tenants who complain [8].
Does the heat law still apply if the tenant pays their own utility bill?
Generally yes. Even when a tenant pays the gas or electric bill directly, the landlord typically remains responsible for making sure the heating system itself works and can produce the legally required minimum temperature. The heat requirement is about system function and habitability, not who pays the utility invoice.
