1. The Warranty of Habitability: the Legal Foundation of Every New York Tenancy
The warranty of habitability is not a contractual option in New York. It is a non-waivable legal obligation embedded in every residential lease under Real Property Law § 235-b, and it forms the bedrock of New York tenant rights across all housing types. Whether your unit is rent-stabilized, market-rate, or subsidized, your landlord is legally required to maintain your apartment in a safe, sanitary, and livable condition throughout the duration of your tenancy. This obligation cannot be signed away in a lease, and any provision attempting to waive it is unenforceable as a matter of law.
Understanding this principle in practical terms is critical to knowing when you have the right to act.
What Conditions Violate the Warranty of Habitability?
A violation of the warranty of habitability occurs whenever a condition in your apartment materially affects your health, safety, or ability to use the unit as a residence. Courts in New York have consistently recognized a broad range of qualifying conditions, including persistent rodent or insect infestations, water leaks that damage walls or flooring, broken heating systems during the winter months, non-functional plumbing, structural damage, and hazardous mold growth. Lead paint exposure is a particularly serious category, as New York City Local Law 1 of 2004 imposes affirmative duties on landlords to inspect and remediate lead paint hazards in units where children under six years old reside. If your landlord fails to address any of these conditions after receiving written notice, you have the right to pursue rent abatement, meaning a court-ordered reduction in the rent you owe proportional to the period and severity of the habitability failure.

Heat Season Requirements and Essential Service Obligations
New York City's Heat Season rules are among the most strictly enforced habitability regulations in the country. From October 1 through May 31, landlords are required by the New York City Administrative Code § 27-2029 to maintain indoor temperatures of at least 68 degrees Fahrenheit between 6:00 a.m. .nd 10:00 p.m. .hen outdoor temperatures fall below 55 degrees, and at least 62 degrees overnight. Hot water must be provided continuously at a minimum temperature of 120 degrees Fahrenheit at the tap throughout the entire year. A landlord who allows heat or hot water to lapse even for a single night is in violation of this obligation, and tenants who experience these failures have the right to file a complaint with the New York City Department of Housing Preservation and Development (HPD), seek rent reduction through the New York City Rent Guidelines Board, or bring a warranty of habitability claim directly in Housing Court. Our housing law team regularly represents tenants in exactly these types of actions.
2. Rent Stabilization Laws and the Transformative Impact of the Hstpa of 2019
NYC rent stabilization laws govern approximately one million apartments in New York City, making them the single most important regulatory framework for renters in the five boroughs. New York tenant rights under the rent stabilization system include the right to a written lease, the right to renew that lease, and the right to have any rent increases capped at levels established annually by the Rent Guidelines Board (RGB). For the lease period beginning October 1, 2024, the RGB approved increases of 2.75 percent for one-year renewals and 5.25 percent for two-year renewals, reflecting the kind of modest, regulated growth that distinguishes stabilized housing from the open market.
How Did the Hstpa of 2019 Strengthen Tenant Protections?
The Housing Stability and Tenant Protection Act of 2019, known as the HSTPA of 2019, fundamentally restructured the balance of power between landlords and tenants across New York State, and its effects continue to shape the legal landscape today. Prior to the HSTPA, landlords had access to several mechanisms that allowed them to substantially raise rents or remove units from stabilization entirely, including vacancy bonuses, major capital improvement (MCI) rent increases, and individual apartment improvement (IAI) allowances.
The 2019 legislation eliminated the vacancy bonus altogether, capped MCI increases at three percent per year and required their eventual expiration, and significantly limited IAI increases to a maximum of $89 per month for improvements costing up to $15,000. The law also eliminated high-rent and high-income deregulation thresholds, which previously allowed landlords to remove stabilized apartments from the regulatory system once rents crossed a certain threshold. As a result of the HSTPA of 2019, the path to deregulation has been effectively closed for the vast majority of stabilized units, and tenants now enjoy far stronger long-term rent predictability. Our rent stabilization practice handles disputes arising from improper deregulation attempts and overcharge claims. You can also explore the rent stabilized law page for more background.
Security Deposit Laws in New York: Limits, Returns, and Legal Remedies
New York's security deposit laws underwent a significant overhaul as part of the HSTPA of 2019, creating uniform statewide protections that apply to virtually all residential tenants. Under General Obligations Law § 7-108, landlords are now prohibited from collecting a security deposit in excess of one month's rent, regardless of whether the unit is stabilized or market-rate. This one-month cap closed the prior loophole that allowed landlords in market-rate housing to demand larger upfront sums. Upon the termination of the tenancy, the landlord must return the security deposit, along with an itemized statement of any deductions, within 14 days of the tenant vacating the unit.
A landlord who fails to return the deposit within this deadline, or who withholds funds without providing an adequate written explanation, forfeits the right to retain any portion of the deposit and becomes liable for the full amount plus court costs. Tenants who have faced unlawful deposit withholding should review our security deposit law resources and consider taking legal action promptly. The Notice of Non-Renewal obligation also applies in this context: for tenants who have lived in a unit for more than one year, landlords must provide written notice at least 30 days before the lease expires if they do not intend to renew, and this requirement extends to 90 days for tenants who have resided in the unit for more than two years.
3. New York Eviction Protections: How to Defend against Unlawful Removal
New York eviction protections are among the strongest in the nation, and they apply at every stage of the eviction process, from the initial notice to the Housing Court proceeding itself. Under Real Property Actions and Proceedings Law (RPAPL), a landlord cannot legally remove a tenant from a residential unit without first obtaining a court order through a formal summary proceeding. No tenant in New York can be legally evicted without a court judgment, and any landlord who attempts to bypass this process, whether by changing locks, removing doors, cutting off utilities, or removing the tenant's belongings, commits an illegal eviction and may be subject to both civil liability and criminal prosecution under Real Property Law § 853. The damages available for illegal eviction include three times the actual damages suffered, making this a significant area of legal exposure for landlords who act outside the law.
What Constitutes an Illegal Eviction under New York Law?
An illegal eviction occurs whenever a landlord takes any self-help action designed to force a tenant out of their home without going through the proper court process. This includes, but is not limited to, padlocking or changing the locks without a court order, removing the tenant's furniture or personal property, terminating essential services such as heat, hot water, or electricity as a pressure tactic, or physically threatening or intimidating the tenant.
These actions are unlawful regardless of whether the tenant owes back rent, regardless of whether the lease has technically expired, and regardless of whatever informal agreements may have been reached between the parties. Tenants who are subjected to these tactics have the right to seek an emergency order from Housing Court restoring them to possession immediately, often on the same day the petition is filed. Our unlawful eviction claims team handles these emergency matters with the urgency they require, and our landlord harassment practice addresses the broader pattern of intimidation that often accompanies these situations.
4. Right to Counsel: Free Legal Representation in Housing Court
The Right to Counsel law, formally known as New York City Local Law 136 of 2017 and codified in the New York City Administrative Code § 26-1301, guarantees free legal representation to income-eligible tenants facing eviction proceedings in Housing Court. As of 2023, this right has been expanded across all five boroughs, and the income threshold has been set at 200 percent of the federal poverty level.
For tenants who qualify, the city will provide a fully-funded attorney at no cost to represent them throughout the eviction proceeding, including appeals. Research has consistently shown that represented tenants are significantly more likely to remain in their homes than unrepresented tenants, and the Right to Counsel program has been credited with dramatically reducing eviction rates across the city since its implementation. Even tenants who do not qualify for free representation benefit from a legal environment in which the opposing party is more likely to be represented, as this has led to more rigorous procedural compliance and increased opportunities for negotiated settlements. Our tenant rights attorneys can help you determine whether you qualify for this program and what options are available if you do not. Separately, the good cause eviction law provides additional protections for tenants in market-rate units who may not otherwise be covered by rent stabilization rules.
5. Building Your Case: Evidence, Documentation, and the Strategic Role of Legal Counsel
New York tenant rights are only as powerful as your ability to enforce them, and enforcement requires evidence. Courts in New York, particularly Housing Court and the Civil Court of the City of New York, rely heavily on documentary evidence when evaluating habitability claims, rent overcharge petitions, and eviction defenses. The single most important thing a tenant can do when a dispute begins to develop is to create and preserve a contemporaneous record of every interaction with the landlord, every notice sent or received, and every condition that affects the habitability of the unit.
How to Document Violations and Preserve Evidence Effectively
Effective documentation begins with written communication. Every repair request should be submitted in writing, whether by email, text message, or certified mail, so that you have a timestamped record that the landlord was notified of the problem and failed to act. Photographs and videos should be taken immediately upon discovering any condition that may constitute a habitability violation, and these files should be saved with their original metadata intact so that courts can verify the date and location of the images.
Tenants should also maintain a written log of oral communications with their landlord, noting the date, time, and substance of each conversation. Where an HPD inspector has visited the unit and issued a violation, that violation notice is powerful evidence and should be preserved carefully. In rent overcharge cases, tenants have the right under the HSTPA of 2019 to obtain the complete rental history of their unit going back up to six years, and this history can reveal patterns of improper deregulation or fraudulent lease manipulation. Our landlord-tenant law attorneys are experienced in conducting these investigations and presenting the results in a format that courts find persuasive.
Anti-Retaliation Protections: Exercising Your Rights without Fear
One of the most important and underutilized protections in New York tenant rights law is the prohibition on landlord retaliation. Real Property Law § 223-b provides that a landlord may not increase a tenant's rent, decrease services, commence or threaten eviction proceedings, or otherwise penalize a tenant in response to the tenant's good-faith exercise of any legal right. Protected activities include filing a complaint with HPD, contacting a government agency about housing conditions, organizing with other tenants, or exercising any right guaranteed by law. If a landlord takes an adverse action within one year of a tenant engaging in protected activity, the law presumes that the action was retaliatory, and the burden shifts to the landlord to prove otherwise.
This is a significant legal protection, because it means that tenants who fear retaliation for speaking up have a legal mechanism available to them that effectively inverts the normal burden of proof. If you have been subjected to retaliatory conduct after reporting conditions or asserting your rights, our housing disputes team can evaluate whether a retaliation claim is available in your case. For tenants whose situations involve a residential lease dispute, or whose landlord has crossed into fraudulent conduct such as misrepresenting stabilization status or fabricating lease terms, our lease fraud and rental fraud practice areas offer additional avenues for legal relief.
