Landlord Laws New York: Tenant Heating Rights

What landlord laws in New York protect

Landlord laws New York tenants rely on are not limited to rent. They also cover habitability, heat, hot water, safe common areas, lead hazards, repairs, and what a landlord can or cannot put in a lease.

For an unsafe-apartment claim, the practical question is usually whether the landlord had notice of the condition, had enough time to respond, and failed to make the apartment or building safe. Written proof is stronger than memory alone.

Heating requirements tenants should know

These are the core landlord heating requirements New York State tenants most often need to understand. Exact rules can vary by city or housing program, but New York City heat rules are a useful baseline for many renters.

• Heat season: October 1 through May 31 in New York City.
• Daytime rule: at least 68°F inside from 6 a.m. to 10 p.m. when the outside temperature is below 55°F.
• Night rule: at least 62°F inside from 10 p.m. to 6 a.m., regardless of the outdoor temperature.
• Hot water: required 365 days a year at a constant minimum temperature of 120°F.

Those figures come from the city's Department of Housing Preservation and Development. State law points the same way for the buildings it covers: Multiple Dwelling Law 79 requires multiple dwellings to be provided with heat and, between October 1 and May 31, sets minimum temperatures that include 68°F from 6 a.m. to 10 p.m. whenever it is below 55°F outside.

If you use a portable heater while building heat is out, use it safely. The U.S. Consumer Product Safety Commission advises keeping portable heaters at least three feet from drapes, furniture, bedding and other combustible materials, plugging electric space heaters directly into a wall outlet rather than an extension cord or power strip, and turning heaters off when sleeping (CPSC, January 2026). A space heater does not replace the heat the landlord is required to provide.

The warranty of habitability

Under Real Property Law 235-b, every residential lease includes a promise that the apartment and the areas used in common with other tenants are fit to live in and that tenants will not be subjected to conditions that are dangerous, hazardous or detrimental to their life, health or safety. Any lease clause waiving or modifying that promise is void as contrary to public policy.

That is why a lease term cannot take away your right to heat or safe housing, even if the lease assigns some responsibilities to the tenant.

The warranty has limits. The same section says a condition caused by the misconduct of the tenant, or of people under the tenant's direction or control, is not a breach. And a habitability problem, on its own, does not prove an injury claim.

How to document a repair problem

A clear file helps whether the issue is heat, a dangerous stairway, water damage, lead based paint, or a rent dispute tied to repairs. Save records as the problem develops, not weeks later.

• A copy of the lease term, renewal offer, rent regulated rider and rent increase notices
• Photos of broken heat, water damage, lead based paint hazards, pests, locks, stairs or lighting
• Texts, emails, certified letters, 311 complaints, inspection reports and repair dates
• Medical records, damaged-property receipts, temporary housing costs and witness names

Common tenant-rights issues

• Heat, hot water and heating season complaints

  What it usually involves Basic services the landlord must provide and the local heat rules. In a multiple dwelling, the record should show when heat failed, what temperatures were measured and how the landlord responded.

  Records that help Dated temperature readings, written complaints, 311 complaint numbers and HPD inspection results

• Unsafe building conditions

  What it usually involves Leaks, mold, broken stairs, missing handrails, bad locks, electrical hazards, rodents and poor lighting can become more than an inconvenience when they create injury risk.

  Records that help Photos before the condition is repaired or painted over, and every repair request

• Lead based paint and older apartments

  What it usually involves Peeling paint and dust in older housing, especially homes with young children

  Records that help Photos, prior complaints, and medical testing or inspection records if exposure is suspected

• Rent, lease and renewal disputes

  What it usually involves A rent regulated apartment, a sudden rent increase or a disputed lease term may involve different rules than an unregulated market-rate apartment.

  Records that help The lease, renewal offers, rent history, preferential-rent notices and every written demand

If the landlord does not respond

The safest next step depends on the condition and the building. A heat outage in winter, a spreading leak, a broken entry lock or peeling paint near a child may require faster action than a cosmetic repair. The goal is to create a record without making a rent or lease problem worse.

1. Give the landlord written notice and keep a copy of the message or letter.
2. Photograph the same condition over time so the duration is clear.
3. Use 311 or the proper housing agency when the condition is urgent or ignored.
4. Get medical care if the condition affects breathing, causes a fall, burns someone or exposes a child to lead risk.
5. Avoid withholding rent or breaking a lease without advice, because the right strategy depends on the apartment, the lease and the local housing rules.

Complaining is protected in most rentals. Under Real Property Law 223-b, a landlord may not serve a notice to quit or start an eviction case in retaliation for a tenant's good-faith complaint to the landlord or a government agency about a violation of a health or safety law. The protection has limits: the section does not apply to owner-occupied dwellings with fewer than four units, and it does not apply where the condition complained about was caused by the tenant, a member of the tenant's household or a guest.

When a housing issue becomes an injury case

Not every landlord dispute is a personal injury case. A habitability problem can support a claim for reduced rent, while an injury claim must show that the landlord's failure to repair or maintain the property caused the harm. Ignored repairs can cause falls, burns, breathing problems, lead exposure, security incidents or other harm. That is when medical documentation and notice to the landlord become especially important. Multiple dwellings must also be kept in good repair under Multiple Dwelling Law 78; our guide to negligent property management explains how notice and responsibility work in injury cases.

If the condition involves a public housing authority, a city agency, a sidewalk or another public body, the deadline to give notice can be much shorter than the ordinary lawsuit deadline and depends on the entity. See how to sue a city or public agency in New York.

For private buildings, the same timeline still matters. The landlord may repair the defect, replace a lock, repaint a wall or discard maintenance records before the tenant knows what proof is needed. A simple file of photos, written complaints and treatment records can make the difference between a vague complaint and a documented claim.
