TL;DR
New York State's Multiple Residence Law and most local codes (including NYC's) require heat during the Oct 1 to May 31 season: at least 68°F indoors during the day when it's below 55°F outside, and 62°F overnight regardless of outdoor temp. Rules and enforcement vary by city; landlords who don't comply face fines, repair orders, and sometimes rent abatement claims.
What are New York's heat requirements for landlords?
New York doesn't have one single statewide heat statute that covers every rental in every county the way people sometimes assume. What exists is a patchwork: the Multiple Residence Law and Multiple Dwelling Law set minimum standards for certain building classes, and then individual cities layer their own housing codes on top, with New York City's rules being the most detailed and most enforced in the country. The baseline that most New York tenants and landlords actually operate under, whether by state law, local code, or both, is this: during "heat season," running from October 1 through May 31, indoor temperatures must hit at least 68°F between 6 a.m. and 10 p.m. whenever the outside temperature drops below 55°F, and at least 62°F overnight (10 p.m. to 6 a.m.) regardless of what it's doing outside [1]. New York City's Housing Maintenance Code spells this out in NYC Administrative Code §27-2029, and it's the version most other New York municipalities reference or mirror when they write their own rental codes [1]. If you're a landlord outside NYC, don't assume you're exempt. Check with your city or town's code enforcement or rental licensing office, because plenty of upstate cities (Rochester, Syracuse, Buffalo, Albany) and even some towns have adopted the same heat season and temperature thresholds through their own local property maintenance codes, often built on the New York State Uniform Fire Prevention and Building Code and the Property Maintenance Code of New York State [2].
When does heat season start and end in New York?
Heat season in New York State runs October 1 through May 31 under the NYC Housing Maintenance Code and the standard most other municipalities use [1]. That's an eight-month window, longer than what a lot of other cold-climate states require. Outside that window, from June through September, there's generally no legal heating mandate, though a building still needs to be habitable overall under warranty of habitability principles that apply statewide. If a freak cold snap hits in early June, most local codes won't require you to turn the heat back on, though a reasonable landlord dealing with a genuinely uninhabitable unit is taking a real legal and PR risk by ignoring tenant complaints. A few smaller municipalities set slightly different date ranges in their local codes, so confirm with your city rental licensing office or code enforcement department before you assume October 1 applies everywhere you own property.
What indoor temperature must a landlord maintain?
| 6 a.m. to 10 p.m. | Outdoor temp below 55°F | 68°F | |
|---|---|---|---|
| 10 p.m. to 6 a.m. | Always, during heat season | 62°F | The outdoor trigger only matters for the daytime rule. At night, the 62°F floor applies no matter what the thermometer outside says, which surprises a lot of landlords who assume mild nights let them ease off. They don't, at least not under the NYC standard most municipalities in the state follow [1]. These are minimums, not targets. A tenant complaint that the apartment is 65°F at 2 p.m. when it's 40°F outside is a legitimate violation under this framework, even if the building's boiler is technically "working." |
The specific numbers matter more than most landlords realize, because inspectors and housing court judges use them as the test. Daytime (6 a.m. to 10 p.m.): indoor temperature must be at least 68°F whenever outdoor temperature falls below 55°F [1]. Nighttime (10 p.m. to 6 a.m.): indoor temperature must be at least 62°F, regardless of outdoor temperature [1]. | Time period | Trigger | Minimum indoor temp |
What happens if a landlord violates NYS heat requirements?
Consequences scale with how bad the problem is and how long it goes unaddressed, and NYC treats heat and hot water violations seriously compared to most maintenance issues. In New York City, a heat violation is generally classified as a Class C (immediately hazardous) violation under the Housing Maintenance Code, and Class C violations carry civil penalties that increase the longer the violation stays open and whether it's a repeat offense. New York City's Administrative Code §27-2115 sets out the civil penalty structure for Housing Maintenance Code violations, including higher per-day penalties for Class C violations [3]. HPD also treats heat complaints as a seasonal priority, since call volume to the city's complaint system spikes every winter [1]. Beyond fines, tenants in New York can pursue a few different remedies depending on jurisdiction: rent abatement through housing court, an HP (Housing Part) proceeding to force repairs, or in extreme or repeated cases, a request that the city perform emergency repairs and bill the owner, a mechanism authorized under New York City Administrative Code §27-2153 (the Emergency Repair Program) [4]. None of these outcomes are guaranteed and all depend on documentation, inspection findings, and how the specific court or agency handles the case, so treat any of this as a general description of the process rather than a prediction of what will happen with a specific building. Upstate cities generally enforce through their own code enforcement departments, and penalties vary by municipality, sometimes running as simple civil fines per violation per day, sometimes escalating for repeat violators. Confirm current penalty schedules with your specific city's code enforcement or rental licensing office before assuming NYC numbers apply.
How to become a landlord in New York and stay compliant on heat
If you're asking "how to become a landlord," heat compliance is one piece of a bigger checklist, not a standalone task. Broadly, becoming a landlord in New York means: acquiring a legal rental property, checking whether your city requires rental registration or licensing (many do), passing any required inspections, and understanding both state landlord-tenant law (the Real Property Law and, for NYC, the Housing Maintenance Code) and local ordinance requirements layered on top. Heat is one of the most inspected and most complained-about items in that whole system, especially in winter. A functioning, correctly-sized heating system that can hit 68°F daytime and 62°F overnight under worst-case outdoor conditions isn't optional infrastructure, it's baseline habitability under New York's warranty of habitability, which courts have applied to residential leases statewide since Real Property Law §235-b [5]. If you're building out a compliance routine as a new landlord, the practical order looks like: confirm your city's registration or licensing requirement, get your heating system inspected and serviced before October 1, keep a maintenance log and any fuel delivery or service records, and know your local code enforcement contact before you have a mid-January emergency.
What is landlording, and what is a landlord, exactly?
A landlord is the owner (or an owner's authorized agent) who leases residential or commercial property to a tenant in exchange for rent, and who holds specific legal obligations under state and local law in return, heat being one of the clearest examples. "Landlording" is the ongoing work of managing that relationship and that property: collecting rent, handling repairs, meeting code requirements, screening tenants, managing move-in and move-out, and responding to complaints. It's part legal compliance, part maintenance, part customer service, and in cities with mandatory registration or licensing, part paperwork management too. New York's Real Property Law defines the landlord-tenant relationship and its baseline duties, and the warranty of habitability under RPL §235-b requires that residential premises be fit for human habitation and not subject the tenant to conditions dangerous to life, health, or safety [5]. Heat, in a New York winter, is squarely inside that definition. A landlord who ignores it isn't just risking a fine, they're risking the legal argument that the unit isn't habitable at all.
How to be a landlord: a practical heat-season checklist
Being a functional, low-drama landlord in New York during heat season comes down to a short list of habits, done consistently rather than perfectly. First, service the heating system before the season starts, not after the first complaint. Boilers and furnaces fail more in the first cold snap of the year than at any other point, and a service record from September is worth more than any argument you make in January. Second, know your numbers cold: 68°F daytime when it's below 55°F outside, 62°F overnight always, October 1 through May 31 [1]. Write them down somewhere your property manager or super can see them. Third, respond fast to heat complaints specifically. These are among the complaints most likely to escalate to code enforcement or an emergency repair referral, faster than almost any other maintenance issue [4]. A slow response on a leaky faucet costs you a bad review. A slow response on heat in January can cost you a Class C violation and daily penalties [3]. Fourth, keep a paper trail: service dates, thermostat logs if you have smart thermostats, tenant communication timestamps. If a violation ever gets disputed, this is what saves you. If you own in multiple cities with different registration or licensing rules, this is exactly the kind of documentation gap that gets landlords in trouble, and it's the reason a one-time prep packet built around your specific city's requirements (see the $79 City Rental License & Inspection Prep Packet) can save real hours versus trying to reconstruct compliance history from memory during an inspection.
What can a landlord look at during an inspection?
During a routine or complaint-driven rental inspection, an inspector (city code enforcement, or in NYC, an HPD or DOB inspector) can generally check: smoke and carbon monoxide detector function and placement, heating system operation and actual measured indoor temperature, water heater condition, structural issues like cracked ceilings or unsafe stairs, pest evidence, electrical hazards, and window guards where required by local law. What an inspector generally cannot do is search the unit for anything unrelated to habitability or code compliance, rifle through personal belongings, or conduct the inspection without proper notice except in a genuine emergency (active gas leak, fire, structural collapse risk). Most municipal codes require reasonable advance notice for non-emergency inspections, though the specific notice period varies by city and by whether it's a landlord-requested inspection versus a code enforcement follow-up. For multi-unit landlords managing inspections across different cities, this is genuinely one of the more confusing parts of the job, because "reasonable notice" in one city's ordinance might mean 24 hours and in another might mean 48 or 72. Confirm the specific requirement with each city's rental licensing or code enforcement office rather than assuming your home city's rule travels with you.
Who is responsible for a rental walk-through inspection, and does that differ in California?
In New York, responsibility for scheduling and conducting a rental inspection, whether it's a pre-lease walk-through, a licensing inspection, or a complaint-driven code enforcement visit, generally falls on the landlord to arrange and the city (or its designated inspector) to conduct if it's a mandatory program inspection. California handles move-in and move-out walk-throughs a bit differently at the state level. Under California Civil Code §1950.5, landlords must, if requested by the tenant, conduct an initial move-out inspection before the tenant vacates, give the tenant an itemized statement of anticipated deductions, and allow the tenant an opportunity to fix cited deficiencies before move-out [6]. That's a landlord-initiated, tenant-requested process focused on security deposit deductions, distinct from a city's mandatory rental licensing inspection. So the short answer: for security deposit walk-throughs, it's the landlord's responsibility to conduct them (and California law gives tenants a right to request one before move-out). For code compliance or licensing inspections tied to a rental registration program, it's typically a government inspector who conducts the actual walk-through, with the landlord responsible for scheduling access and remedying anything flagged.
What rights do tenants have without a lease?
A tenant without a written lease in New York generally becomes a month-to-month tenant at will, and month-to-month tenants still get the state's core statutory protections, including the warranty of habitability under RPL §235-b [5], protection from illegal lockout or self-help eviction, and (in New York City and other rent-stabilized contexts) additional procedural protections. Heat requirements apply regardless of lease status. A landlord can't argue their way out of the 68°F/62°F standard because a tenant is month-to-month or never signed a formal lease. The obligation runs with the rental relationship, not the paperwork. Where lease status matters most is notice and termination: month-to-month tenants generally get shorter statutory notice periods before a landlord can terminate the tenancy compared to a fixed-term lease that simply expires. New York's Real Property Law §226-c requires landlords to give written notice before a rent increase of 5% or more or before non-renewal, with the required notice period scaling by how long the tenant has lived there: 30 days for tenancies under one year, 60 days for one to two years, and 90 days for tenancies over two years [7].
How much notice does a landlord have to give in New York?
Notice requirements in New York vary by what's happening, and this is one of the more commonly confused parts of the law because different situations trigger different rules. For rent increases of 5% or more, or non-renewal of a lease, RPL §226-c requires: 30 days' notice if the tenant has occupied the unit less than one year, 60 days if between one and two years, and 90 days if two years or more [7]. For entry to make repairs or conduct inspections, New York doesn't have one single statewide statute dictating a specific number of hours or days for all rentals; NYC and rent-stabilized units have their own specific access rules, and general common-law and lease-based "reasonable notice" standards apply elsewhere. Most local rental codes and standard lease language use 24 to 48 hours as the practical norm, but confirm the specific requirement in your city's rental housing code before relying on it. For eviction proceedings, New York's Real Property Actions and Proceedings Law (RPAPL) sets out notice-to-quit and petition timelines that vary by the grounds for eviction (nonpayment, holdover, lease violation) and are stricter and longer in New York City under the Housing Stability and Tenant Protection Act of 2019 framework. This is genuinely a case where you want a landlord-tenant attorney or your city's housing court self-help center rather than a general guide, since the details change the outcome.
Why do landlords require renters insurance?
Landlords require renters insurance mainly to shift liability and property risk away from themselves and onto a policy the tenant controls. If a tenant's stove fire damages their own belongings, a landlord's own building insurance typically covers the structure but not the tenant's personal property, and without renters insurance, an aggrieved tenant sometimes tries to hold the landlord financially responsible anyway, even when the landlord did nothing wrong. Renters insurance also typically includes liability coverage, which matters if a tenant's dog bites a visitor, or a tenant's negligence (an overflowing bathtub, an unattended candle) damages a neighboring unit. That liability coverage protects the landlord from getting pulled into costly disputes between tenants or between a tenant and a third party. New York State doesn't mandate renters insurance by statute the way some cities require specific coverage minimums for landlords' own liability policies, but a landlord can legally require it as a lease condition in most cases, provided the requirement is applied consistently and doesn't violate fair housing law. Requiring it, and verifying it's actually in force with an annual certificate, is cheap insurance against a much messier dispute later.
What can't a landlord do in Ohio, and how does that compare to New York?
Since landlords sometimes own property across state lines, it's worth flagging where Ohio law diverges from New York's approach, because the rules genuinely aren't the same. In Ohio, under Ohio Revised Code §5321.04, a landlord cannot: shut off utilities to force a tenant out, remove doors or windows, change locks without proper legal process, or otherwise engage in self-help eviction; the landlord must maintain the premises in a fit and habitable condition, keep common areas safe, and maintain electrical, plumbing, heating, and other systems supplied by the landlord in good working order . Ohio law does not specify the same rigid degree-and-date heat standard NYC uses; instead it uses a general habitability and "good working order" standard for heating equipment, which gives Ohio landlords more day-to-day discretion but also more ambiguity about exactly when a heat complaint becomes an actionable violation. New York's approach, at least in NYC and municipalities that mirror its code, is more specific and more mechanically enforceable: hit 68°F/62°F on the clock, in the season, or you're in violation, full stop, with a published penalty structure behind it [1][3]. If you own in both states, don't assume Ohio's more general standard means you have the same wiggle room in New York. You don't.
How does New York's heat rule compare to other cold-weather states?
| New York City (NYC HMC) | Oct 1 to May 31 | 68°F (when outside <55°F) | 62°F | |
|---|---|---|---|---|
| Chicago (Municipal Code) | Sept 15 to June 1 | 68°F (daytime) | 66°F (overnight) | |
| Ohio (ORC 5321.04) | No fixed season/temp; general "good working order" standard | Not specified | Not specified | Chicago's Municipal Code §5-12-050 sets a longer season (Sept 15 to June 1) but a slightly higher overnight minimum (66°F) than New York's 62°F . That's a useful comparison for landlords deciding how much slack they actually have: New York gives you a colder overnight floor to hit, but Chicago starts and ends its mandatory season earlier and later in the calendar. The practical lesson for any multi-city landlord: never assume the numbers from one city travel to another, even within the same general climate zone. Confirm with your city rental licensing office. |
New York's 68°F daytime / 62°F overnight standard, with an eight-month heat season, is on the stricter and longer end nationally, though it's not unique in structure. Many cold-climate cities and states use a similar two-tier day/night temperature approach, just with different numbers or season lengths. | Jurisdiction | Heat season | Daytime minimum | Nighttime minimum |
Where to check your specific city's heat and rental rules
Because so much of this varies by municipality, the single most useful thing a New York landlord can do is find and bookmark their specific city's code enforcement or rental licensing office page, rather than relying on the NYC standard as a universal default. For NYC properties specifically, the NYC Administrative Code sections on Housing Maintenance Code violations (§27-2115) and emergency repairs (§27-2153) are the authoritative source [3][4]. For anywhere else in the state, contact your city or town's code enforcement department directly and ask three questions: what's the exact heat season date range, what's the minimum temperature standard, and what's the penalty structure for violations. If you're managing rentals across more than one city, or you're getting your first notice from a city rental licensing office and don't know where to start, that's exactly the kind of scattered, city-specific paperwork problem the $79 City Rental License & Inspection Prep Packet is built to sort out in one pass, rather than you hunting down each requirement separately under deadline pressure. And if you're new to owning rental property generally, it's worth reading up on broader tenant rights and renters rights frameworks too, since heat compliance sits inside a much bigger web of habitability and notice obligations that trip up first-time landlords more than seasoned ones.
Frequently asked questions
What temperature is a landlord legally required to keep an apartment in New York?
Under the standard most New York municipalities use (based on NYC's Housing Maintenance Code), landlords must maintain at least 68°F indoors from 6 a.m. to 10 p.m. when it's below 55°F outside, and at least 62°F overnight from 10 p.m. to 6 a.m., every day during heat season, October 1 through May 31.
What months does heat season cover in New York?
Heat season runs October 1 through May 31 under the standard most New York cities follow, an eight-month window. Outside that period there's generally no mandatory heat requirement, though the unit must stay habitable overall under the state's warranty of habitability law.
How to become a landlord in New York?
Broadly: buy or inherit rental property, check whether your city requires rental registration or licensing, get any required pre-rental inspections done, understand state landlord-tenant law (Real Property Law) plus your city's housing code, and set up a compliance routine covering heat, smoke/CO detectors, and habitability basics before you list the unit.
Who is responsible for a rental walk-through inspection in California?
For move-out deposit disputes, California Civil Code §1950.5 gives tenants the right to request an initial inspection before move-out, which the landlord conducts and documents. For mandatory rental licensing or code inspections, a government inspector typically conducts the walk-through, with the landlord responsible for scheduling access.
What is landlording?
Landlording is the day-to-day work of owning and managing rental property: collecting rent, handling repairs and code compliance, screening and communicating with tenants, and meeting whatever registration, licensing, or inspection requirements your city imposes. It's a mix of legal compliance, maintenance, and tenant relations.
What rights do tenants have without a lease in New York?
A tenant without a written lease generally becomes a month-to-month tenant at will and keeps core statutory protections, including the warranty of habitability (RPL §235-b), protection from illegal lockout, and notice requirements before rent increases or non-renewal under RPL §226-c. Heat requirements apply regardless of lease status.
Why do landlords require renters insurance?
Mainly to shift liability off the landlord: renters insurance covers the tenant's personal property loss and includes liability coverage if the tenant's negligence causes injury or damage to others. It reduces the chance a landlord gets pulled into a dispute over something the tenant, not the landlord, is actually responsible for.
How much notice does a landlord have to give before raising rent in New York?
Under RPL §226-c, a landlord must give 30 days' notice for tenancies under one year, 60 days for one to two years, and 90 days for tenancies of two years or more, whenever the increase is 5% or greater, or when not renewing the lease.
What can a landlord look at during a rental inspection?
Inspectors typically check smoke and CO detectors, heating system function and actual indoor temperature, water heater condition, structural safety, pest evidence, electrical hazards, and window guards where required. They generally can't search personal belongings or inspect without reasonable notice except in genuine emergencies like an active gas leak.
What can't a landlord do in Ohio?
Under Ohio Revised Code §5321.04, an Ohio landlord can't shut off utilities to force a tenant out, remove doors or windows, change locks without legal process, or otherwise self-help evict. The landlord must keep the unit fit and habitable and maintain heating, plumbing, and electrical systems in good working order.
What happens if my landlord won't turn the heat on in New York?
File a complaint with your city's code enforcement office, or in NYC call 311 or use HPD's online complaint system. Persistent violations can lead to Class C violation penalties for the landlord, an HP proceeding to force repairs, rent abatement claims, or a request that the city perform emergency repairs and bill the owner.
Does New York's heat law apply to landlords outside New York City?
Many upstate cities have adopted the same or a very similar 68°F/62°F, October-to-May standard through their own local housing or property maintenance codes, but it's not automatic statewide. Confirm the exact season dates and temperature minimums with your specific city's code enforcement or rental licensing office.
