TL;DR
Yes. NYC landlords must provide heat from October 1 through May 31 whenever outdoor temps drop below certain thresholds, keeping indoor temps at least 68°F daytime (below 55°F outside) and 62°F overnight, per NYC Housing Maintenance Code §27-2029. Violations bring HPD inspections and civil penalties that can exceed $1,000 per day for repeat offenses.
Are NYC landlords legally required to provide heat?
Yes. New York City's Housing Maintenance Code requires owners of residential buildings to provide heat during a fixed "Heat Season" every year, and the requirement applies regardless of what a lease says. You cannot contract out of it. A landlord who tells a tenant "heat isn't included" in a multi-unit residential building is, with rare exceptions, simply wrong or breaking the law. The rule lives in the NYC Administrative Code, Housing Maintenance Code Title 27, Chapter 2, Article 11, specifically §27-2029, which the city calls the "Heat and Hot Water" provision. The Department of Housing Preservation and Development (HPD) enforces it, and 311 is the intake line for tenant complaints. HPD describes the obligation directly: owners must maintain indoor temperatures at set minimums during Heat Season "regardless of the weather" once the outdoor threshold is hit [1]. This isn't a New York City quirk invented by regulators with nothing better to do. It reflects a public health reality: cold apartments contribute to respiratory illness, hypothermia risk for elderly tenants, and burst pipes that cause secondary damage. The city treats heat the same way it treats working smoke detectors, as baseline habitability, not an amenity. If you're a landlord with one to ten units and you've just gotten an ordinance notice or a heat complaint on your building, the practical question isn't whether the rule applies to you. It almost certainly does. The real question is what the temperature and timing rules actually require, and what happens if you miss them.
What are the exact heat season dates and temperature rules in NYC?
| 6:00 a.m. to 10:00 p.m. | Below 55°F | At least 68°F | |
|---|---|---|---|
| 10:00 p.m. to 6:00 a.m. | Any outdoor temperature | At least 62°F | Source: NYC Administrative Code §27-2029 and HPD's Heat and Hot Water guidance [1][2]. Notice the overnight rule has no outdoor trigger. From 10 p.m. to 6 a.m., landlords must maintain 62°F inside no matter how warm or cold it is outside, as long as it's Heat Season. During the day, the 68°F requirement only kicks in once the outdoor temperature drops below 55°F. Hot water is a separate, year-round requirement. NYC building owners must supply hot water at a minimum of 120°F, 365 days a year, more than during Heat Season [1]. A lot of landlords conflate the heat rule and the hot water rule; they're both in §27-2029 but they don't share a calendar. |
NYC's Heat Season runs October 1 through May 31 every year, no exceptions for weather forecasts or landlord discretion [1][2]. During that window, the rules split into daytime and overnight requirements: | Time period | Outdoor temperature trigger | Required indoor temperature |
What happens if a landlord doesn't provide heat in NYC?
Tenants file heat complaints through 311 or HPD's website, and HPD can dispatch an inspector, sometimes the same day during cold snaps. If an inspector confirms the apartment is below the required temperature, HPD issues a violation against the building. Civil penalties for heat and hot water violations are steeper than most general HMC violations because the city treats them as immediately hazardous. Under NYC Admin Code §27-2115 and related HPD penalty schedules, heat violations can carry civil penalties ranging roughly from $250 to $1,250 or more per violation per day, with the exact amount depending on building size, whether it's a first offense, and how many days the condition persists [3]. Multiple-dwelling owners with a documented pattern of heat violations that HPD tracks under its "Alternative Enforcement Program" or similar tracking can face escalating penalties and even court action. Beyond civil penalties, HPD can pursue emergency repair actions, meaning the city fixes the heating system and bills the owner, sometimes at a premium over market repair rates. In serious or repeat cases, the city's Department of Buildings or HPD can involve Housing Court, and a pattern of heat violations can affect a building's standing under local anti-harassment and lead paint compliance overlays. For a landlord with a handful of units, one blown boiler control board in January can turn into several hundred dollars in penalties within days if the repair isn't fast. This is why building owners in cold-weather licensing cities generally keep an emergency HVAC contractor on speed dial from September through April, more than when something breaks.
Does the heat requirement apply to single-family homes and small buildings too?
Mostly yes, with some nuance on who's on the hook. The Housing Maintenance Code heat provisions apply to Class A multiple dwellings, generally buildings with three or more residential units, and HPD is the primary enforcer for those [1]. Two-family and owner-occupied properties fall under different code sections (often Multiple Dwelling Law provisions enforced through Housing Court rather than routine HPD inspection sweeps), but the substantive obligation to provide adequate heat during Heat Season still applies in practice; tenants in duplexes and small buildings can still bring a heat complaint and courts have consistently required functioning heat as part of the warranty of habitability under New York Real Property Law §235-b [4]. If you own a small multi-unit building (say 3 to 10 units) and you're getting your first rental registration or licensing notice, don't assume the heat rule is only for big landlords. It isn't. The size of your building affects which department handles the paperwork and possibly the civil penalty schedule, but it doesn't exempt you from the temperature minimums.
Can a landlord shut off heat to force a tenant out?
No, and doing so is one of the more serious things a landlord can be accused of in NYC. Deliberately withholding heat, hot water, or other essential services to pressure a tenant to vacate falls under NYC's tenant harassment provisions, Administrative Code §27-2005, which lists interruption of essential services as one of the enumerated forms of harassment HPD and courts can act on [5]. A tenant who believes heat was cut off intentionally, rather than because of an honest equipment failure, can raise a harassment defense in Housing Court, and HPD can independently investigate and place the building on a harassment watch list. Penalties for a harassment finding are separate from and can stack on top of ordinary heat violation penalties, and a harassment finding can also trigger requirements under the city's certificate of no harassment rules if the building is later involved in permit applications. The honest, practical answer here: if your boiler dies in February, get it fixed as fast as physically possible and document every step, the service call, the parts order, the temporary heaters you brought in if you did. That paper trail is your defense against a harassment allegation, and it also helps if HPD reviews the violation history later.
How does NYC's heat rule compare to other cities' requirements?
| New York City | Oct 1 to May 31 | 68°F (when outside <55°F) | 62°F | |
|---|---|---|---|---|
| Chicago | Sept 15 to June 1 | 68°F (7 a.m., 10:30 p.m.) | 66°F | |
| Boston | Sept 16 to June 15 | 68°F (7 a.m., 1 a.m.) | 64°F | Chicago's heat ordinance and minimums are set out in the Chicago Municipal Code Chapter 5-12-110 [6]; Boston's are enforced through the Massachusetts State Sanitary Code, 105 CMR 410.201 [7]. If you own rental units in more than one city, don't assume NYC's Heat Season dates or minimums transfer. Confirm the current dates and thresholds with your specific city's rental licensing or code enforcement office before winter, because these numbers do occasionally shift with local ordinance updates. This is exactly the kind of city-to-city variance that trips up landlords expanding into a second market. What's legal and routine in one city is a violation waiting to happen in another. If you're prepping paperwork for a rental license or inspection in a new city, our $79 City Rental License & Inspection Prep Packet walks through the city-specific checklist items, including heat and utility requirements, so you're not guessing which rules follow you across city lines. |
NYC's dual daytime/overnight thresholds are more detailed than many cities, but the underlying concept, a fixed heating season plus a minimum indoor temperature, is common across cold-climate rental licensing jurisdictions. Every city sets its own dates and degree minimums, so a landlord who owns in more than one city cannot assume the rules match. | City | Heat season | Daytime minimum | Overnight minimum |
How to become a landlord (the basics, before you worry about heat)
Becoming a landlord in a licensed rental city means more than buying a property and finding a tenant. Most mandatory rental-licensing municipalities, NYC included for certain building types, require registration with a housing agency, a pre-rental or periodic inspection, and payment of a licensing or registration fee before you can legally rent the unit. The general path looks like this: buy or convert the property, confirm local zoning allows residential rental use, register the property with your city's rental licensing office (in NYC, HPD requires multiple dwelling registration, Admin Code §27-2097, renewed annually), schedule any required inspection, fix anything the inspector flags, then sign leases. Skipping the registration step is a common rookie mistake; NYC in particular restricts an owner's ability to recover possession or collect certain rents in court if a required multiple dwelling registration is not on file [8]. What is landlording, in plain terms? It's the ongoing operational job of owning and renting residential property: collecting rent, keeping the building in code (which includes heat, hot water, working smoke and CO detectors, and pest control), handling repairs, and following your city's registration and inspection cycle. It is not a one-time setup task. Cities like NYC, Chicago, and many others require annual or multi-year re-registration and re-inspection, so landlording means staying current on paperwork every single cycle, more than at move-in. What is a landlord? Under most state landlord-tenant statutes, a landlord is simply the owner (or an owner's authorized agent) of residential rental property who has entered into a rental agreement, written or oral, with a tenant in exchange for rent. New York's Real Property Law and Multiple Dwelling Law use similar functional definitions, tying the landlord's habitability obligations, heat included, to ownership or control of the building rather than to having a signed lease in hand [4].
What rights do tenants have without a lease?
Tenants without a written lease, sometimes called month-to-month or holdover tenants, still keep essential legal protections in New York and most states. The warranty of habitability under New York Real Property Law §235-b applies regardless of whether there's a written lease, meaning the landlord still must provide heat, hot water, and a livable, code-compliant unit [4]. A tenant without a lease generally has the right to proper eviction notice (length varies by tenancy duration and local law), protection from illegal lockouts or utility shutoffs used to force them out, the right to a habitable unit including working heat, and, in New York City specifically, rent stabilization protections if the building and unit otherwise qualify, lease or no lease. What a verbal or no-lease tenant does not automatically get is a fixed rent amount or term length beyond what state law defaults to for that tenancy type. That's a real gap, and it's part of why both landlords and tenants are generally better off with something in writing, even a simple month-to-month agreement, rather than relying on oral terms that are hard to prove later.
How much notice does a landlord have to give tenants?
Notice requirements vary by state and by what the notice is for, so there's no single national number, but a few common patterns show up across jurisdictions. For entering a unit for non-emergency repairs or inspection, many states require 24 to 48 hours advance notice; New York doesn't have one single statewide statute mandating a specific number of hours for routine entry, but courts and most leases treat 24 hours as reasonable notice absent an emergency. For ending a month-to-month tenancy or raising rent significantly, New York's "good cause" and notice statutes (Real Property Law §226-c) require 30, 60, or 90 days notice depending on how long the tenant has occupied the unit and the size of any rent increase [9]. For non-payment or lease violation eviction notices, timeframes are shorter and vary by county and case type. Heat repairs are typically treated as urgent, not routine, so "reasonable notice" for entering to fix a heating system during a cold snap is generally much shorter than the standard 24 to 48 hour window; courts recognize emergency repairs as an exception to standard notice rules.
What can a landlord look at during a rental inspection?
A rental inspection, whether it's a city-mandated licensing inspection or a routine unit walkthrough, generally covers life-safety systems and habitability items: smoke and carbon monoxide detectors, working heat and hot water systems, electrical outlets and panel condition, plumbing leaks, window guards where required, egress (are there two ways out in an emergency), and pest or mold conditions. What inspectors and landlords typically cannot do is search personal belongings, closets, or areas unrelated to the code items being checked, and most jurisdictions require advance notice before entry except in emergencies. In NYC specifically, HPD inspectors responding to a heat complaint will check the room temperature with a thermometer and the outdoor temperature at the time of inspection, since both numbers matter for determining whether a violation exists under §27-2029's threshold system [1]. For landlords in California specifically: who is responsible for a rental property walkthrough inspection there? California doesn't run a statewide mandatory rental licensing inspection program the way some cities do; walkthrough inspections there are typically a landlord or property manager responsibility at move-in and move-out under California Civil Code §1950.5, which governs security deposit itemization and requires landlords to document unit condition, not a state inspector's job. Some California cities (Los Angeles, Oakland, and others) layer on their own local rental registration or habitability inspection programs on top of that state deposit law, so always check your specific city's rules.
Why do landlords require renters insurance?
Landlords ask for renters insurance mainly to shift liability risk, not because it's legally mandated in most places. Renters insurance typically covers a tenant's personal belongings and provides liability coverage if the tenant accidentally causes damage (a kitchen fire, a bathtub overflow that damages the unit below). Without it, a landlord's own property insurance may cover the building's structure, but the tenant's belongings and tenant-caused liability often aren't covered, leaving the landlord to absorb disputes or lawsuits that renters insurance would otherwise handle. Many landlords now write a renters insurance requirement directly into the lease, and it's legal to do so in most states as long as it's disclosed upfront and applied uniformly. It's a relatively cheap requirement to enforce and a real risk-reduction tool. It is not, however, a substitute for the landlord's own liability and hazard insurance on the building itself.
What a landlord cannot do in Ohio (and lessons that apply everywhere)
Ohio's landlord-tenant law, chapter 5321 of the Ohio Revised Code, spells out specific landlord obligations and prohibitions. Ohio landlords cannot shut off utilities, remove doors or windows, or otherwise force a tenant out without going through formal eviction in court; this is sometimes called a prohibition on "self-help" eviction, and Ohio Revised Code §5321.15 explicitly bars landlords from using lockouts, utility shutoffs, or removing tenant belongings as an eviction method [10]. Ohio landlords also cannot retaliate against a tenant for reporting a code violation or joining a tenant organization; Ohio Revised Code §5321.02 gives tenants a retaliation defense if a landlord raises rent, decreases services, or files eviction shortly after the tenant made a legitimate complaint . The broader lesson applies well beyond Ohio: essential services like heat, water, and electricity are treated as protected under nearly every state's landlord-tenant code, and cutting them off deliberately, anywhere in the country, is a fast way to turn a maintenance problem into a harassment or illegal-eviction case. NYC's heat harassment provision and Ohio's self-help eviction ban are different statutes solving the same underlying problem: keeping landlords from using deprivation of basic services as a bargaining chip against tenants.
How to be a landlord who stays out of heat trouble
Practically, staying compliant with NYC's heat rule (or any cold-climate city's version of it) comes down to a short list of habits, not a complicated system. Service your boiler or heating system before Heat Season starts, not after the first cold complaint arrives; a fall tune-up costs far less than an emergency service call in January. Keep a written maintenance log, HPD and most code enforcement agencies view documentation favorably when a violation is contested. Know your building's Heat Season dates and thresholds cold (NYC's are fixed by statute, so there's no guessing), and post them somewhere your super or building staff can reference quickly. Respond to heat complaints same-day if at all possible; a fast response is your best defense against both civil penalties and harassment allegations. If you're getting ready for a rental license renewal, a first-time registration, or you just got hit with a violation notice and want to get organized before your next inspection, our $79 City Rental License & Inspection Prep Packet at /rental-packet-builder is built around exactly this kind of checklist, city-specific requirements including heat and hot water compliance, so you walk into your inspection knowing what's actually being checked rather than guessing. This is reference information, not legal advice, and city rules do change, so confirm current fees and deadlines with your local rental licensing office before you rely on anything here for a specific filing.
Frequently asked questions
What temperature is a landlord required to keep an NYC apartment during winter?
NYC landlords must maintain at least 68°F indoors from 6 a.m. to 10 p.m. whenever outdoor temperature drops below 55°F, and at least 62°F indoors overnight from 10 p.m. to 6 a.m. regardless of outdoor temperature, per NYC Administrative Code §27-2029, during the October 1 to May 31 Heat Season.
What months does NYC's Heat Season cover?
NYC's mandatory Heat Season runs October 1 through May 31 every year. During this window, landlords must meet the indoor temperature minimums whenever the outdoor temperature triggers apply. Outside these dates, there's no citywide minimum indoor temperature requirement, though hot water at 120°F minimum is required year-round.
What happens if my NYC landlord won't fix the heat?
File a complaint with 311 or HPD online. HPD can send an inspector, often same-day in cold weather, and issue a violation if the apartment is below the required temperature. Persistent violations can bring civil penalties of roughly $250 to $1,250 or more per day, and repeated failures can trigger harassment investigations.
Is providing heat required even if it's not in my lease?
Yes. The heat requirement comes from NYC's Housing Maintenance Code and New York's warranty of habitability (Real Property Law §235-b), not from lease language. A landlord cannot waive this obligation through a lease clause, and a lease saying heat is excluded or tenant-provided doesn't override the statute for covered buildings.
How to become a landlord in a city that requires rental licensing?
Register your property with the local housing agency, confirm zoning allows rental use, schedule any required pre-rental inspection, correct flagged issues, then lease the unit. In NYC, owners of multiple dwellings must file annual multiple dwelling registration with HPD before renting legally.
Who is responsible for a rental property walkthrough inspection in California?
California doesn't run a statewide mandatory licensing inspection; move-in and move-out walkthroughs are the landlord's responsibility under California Civil Code §1950.5, which governs security deposit documentation. Some cities like Los Angeles or Oakland add their own local rental registration or habitability inspection requirements on top of that.
What is landlording?
Landlording is the ongoing job of owning and operating residential rental property: collecting rent, maintaining code compliance (heat, hot water, safety devices), handling repairs, and keeping up with registration and inspection cycles. It's continuous, not a one-time task, especially in cities requiring annual re-registration.
What is a landlord, legally speaking?
A landlord is the owner, or an owner's authorized agent, of residential property who has entered a rental agreement with a tenant in exchange for rent. Most state landlord-tenant statutes, including New York's, tie habitability obligations like heat to ownership or control of the building, not to having a signed lease.
What rights do tenants have without a lease?
Tenants without a written lease still generally get warranty-of-habitability protections (working heat, hot water, safe conditions), protection from illegal lockouts, and required eviction notice periods under state law. What they typically lack is a fixed rent or term length beyond state default rules, since there's no written agreement specifying those terms.
Why do landlords require renters insurance?
Landlords require it mainly to shift liability risk. Renters insurance covers a tenant's belongings and liability for tenant-caused damage, protecting the landlord from disputes over damage the landlord's own building insurance doesn't cover. It's legal to require in most states if disclosed and applied consistently.
How much notice does a landlord have to give before entering a unit?
It varies by state; many require 24 to 48 hours for routine, non-emergency entry. New York doesn't have one uniform statewide hours requirement, but 24 hours is generally treated as reasonable absent emergency. Urgent repairs, like a broken heating system, are typically treated as exceptions allowing faster entry.
What can a landlord look at during a rental inspection?
Inspectors typically check life-safety and habitability items: smoke and CO detectors, heating and hot water systems, electrical and plumbing condition, window guards, and pest or mold issues. They generally cannot search personal belongings or areas unrelated to code compliance, and advance notice is usually required except in emergencies.
What can't a landlord do in Ohio?
Under Ohio Revised Code §5321.15, landlords cannot use self-help eviction methods like shutting off utilities, changing locks, or removing doors to force a tenant out; formal court eviction is required. Ohio Revised Code §5321.02 also bars retaliation against tenants who report code violations or organize.
