HPD Heat Complaints 2026: What NYC Landlords Must Do

HPD heat complaints don’t wait for business hours. It’s 11:40 p.m. on a cold October night. Your phone lights up: a tenant in 4B says the radiators are dead. Within hours, that tenant can call 311, and HPD will log an HPD heat complaint against your building.

Heat season starts October 1, and for owners the question isn’t whether HPD heat complaints will come, but whether you’re ready. HPD reported 344,437 heat complaints for the 2025-26 season as of May 31, 2026, up 22% from the season before. This guide covers what the law requires, what HPD does after a complaint, what it costs when you get it wrong, and how to respond in a way that protects your building and your budget.

Quick Answer: What Are NYC’s Heat Requirements?

Heat season runs October 1 through May 31. During that window:

• Daytime (6 a.m.-10 p.m.): 68°F minimum when the outdoor temperature is below 55°F
• Nighttime (10 p.m.-6 a.m.): 62°F minimum regardless of the outdoor temperature
• Hot water: 120°F at the tap, 365 days a year, not just in winter

These requirements come from the NYC Housing Maintenance Code. Heat and hot water are essential services, part of the warranty of habitability you owe every residential tenant.

How the NYC Process for HPD Heat Complaints Works

Knowing the tenant’s path helps you anticipate yours.

1. The tenant contacts you first. HPD advises tenants to notify the owner or manager before calling 311.
2. The tenant files a 311 heat complaint. If service isn’t restored, they call 311 or file online. They receive a complaint number.
3. HPD investigates. One 2026-27 guide reports that as of October 1, 2026, HPD investigates each 311 heat complaint individually. Treat every complaint as a separate case with its own clock.
4. An inspector visits. If the apartment is below the legal minimum, HPD issues a violation.
5. Penalties and enforcement begin if the condition isn’t corrected.

A complaint is only a report. A violation reflects an agency finding. That distinction matters, because you can often resolve a complaint before it becomes a violation, if you act quickly.

What Happens When HPD Finds No Heat

HPD heat violations are classified as Class C, immediately hazardous. That’s the most serious tier, with the shortest correction window. Under HPD rules, the condition must be fixed within 24 hours of the violation posting.

Once a violation posts, the financial clock starts. HPD can seek court-ordered civil penalties that accrue per day, per violation, from the posting date until the violation is corrected. Repeat violations at the same building during the same or following heat season are penalized at a higher tier than first-time violations. Local Law 71 strengthened the penalty framework for heat and hot water, so always confirm the current schedule on HPD’s website.

Other consequences stack on top:

• Inspection fees. HPD charges a fee for each inspection after the first two that results in a heat violation within the same heat season.
• Emergency Repair Program. If you don’t fix the problem, HPD may contract with private companies under the Emergency Repair Program to restore services, and you’re billed for the work.
• Rent reductions. For rent-regulated apartments, DHCR is authorized to reduce the rent when required heat and hot water aren’t maintained.
• Litigation. Tenants and HPD can bring cases in Housing Court, including HP actions and the 7A program for buildings with chronic failures.

Repeat HPD heat complaints are the real danger. One bad night is a repair ticket. Five bad nights is a pattern, and patterns become litigation.

How to Respond to HPD Heat Complaints (Step by Step)

When a complaint lands, speed and documentation are your best defenses.

1. Verify within hours, not days. Send your super or a licensed contractor to check the apartment temperature and the boiler. Log the time, the reading, and the tech’s name.

2. Find the root cause. Common culprits include:

• Boiler failure or a tripped low-water cutoff
• A faulty burner or aquastat
• Steam radiator problems such as stuck vents, air lock, or improper pressure
• Air trapped in hot-water baseboard lines
• Fuel delivery gaps
• A single-apartment issue, like a blocked radiator or broken valve

3. Restore heat and get proof. If the boiler is down, arrange emergency boiler repair immediately. Keep invoices, work orders, and timestamps.

4. Communicate with the tenant. Confirm in writing what you found and when heat was restored. A documented, responsive owner looks very different to a judge than a silent one.

5. Check HPD’s records. Look up your building on HPD Online to review HPD heat complaints and open HPD violations. Know exactly what’s on file before an inspector or attorney tells you.

6. Certify correction properly. If a violation posted, heat violations must be resolved immediately and self-certified by mail or eCertification. Fixing the boiler alone doesn’t clear the violation; the certification step is what closes it. Be accurate here, since a false certification is its own offense with its own penalties, and HPD does reinspect.

Why HPD Heat Complaints Happen: The Boiler Is Usually the Culprit

Most heat failures trace back to the heating plant. Deferred maintenance in October becomes a tenant emergency in December.

What owners can do before winter:

• Tune up the boiler before heat season. Combustion testing, burner cleaning, and controls calibration catch problems while they’re small.
• Test safety devices. That means the low-water cutoff, pressure controls, and the aquastat.
• Maintain a boiler maintenance log. Dated service records prove diligence if a case reaches court.
• Stay current on registrations and inspections. Confirm your annual DOB boiler inspection is filed and your DEP CATS boiler registration is up to date.
• Keep the fuel supply reliable. Confirm delivery schedules and tank levels ahead of cold snaps.
• Train your super. They should know the boiler’s shut-down procedure and who to call at 2 a.m.

Inspection-focused providers like OneViewNYC Inspections can help owners identify equipment and compliance gaps before a cold-weather failure turns into an HPD case.

DOB vs. HPD: Don’t Mix Up the Violations

Owners often confuse the two agencies.

• HPD enforces housing maintenance standards, meaning tenants’ access to heat and hot water. Violations follow tenant complaints.
• DOB regulates boiler safety, inspections, and equipment. A boiler violation there is about the equipment’s compliance, not whether apartments are warm.

A building can pass a DOB boiler inspection and still draw an HPD heat violation, for example if distribution problems leave the top floor cold. And a boiler shutdown order can lead to an HPD complaint the same night. Manage both tracks.

Landlord Heat Compliance Checklist

Use this before October 1 and revisit it monthly through May:

• ☐ Boiler serviced and tuned up; safety controls tested
• ☐ DOB inspection filed; DEP CATS registration current
• ☐ Heating and hot-water temperature checks logged across top-floor and end-of-line apartments
• ☐ Emergency contractor contacts saved and reachable 24/7
• ☐ Super trained on troubleshooting and escalation
• ☐ Tenant communication plan ready: how to report no heat, who responds
• ☐ HPD Online reviewed weekly for new HPD heat complaints or violations
• ☐ Repair records, invoices, and certifications filed by date
• ☐ Fuel deliveries scheduled with a buffer for cold snaps

Business Thinking: What Does Compliance Really Cost?

Consider the math. A tuned boiler and a service contract cost a fraction of what one chronic-failure case does. Add per-day penalties, higher tiers for repeat violations, inspection fees, emergency repair charges, possible rent reductions, and legal fees, and the cost of inaction climbs fast. There’s also a quieter cost: tenants who feel ignored leave, vacancies rise, and your building’s reputation follows.

For portfolio owners, the smart move is a system. Track HPD heat complaints by building, flag repeat locations, and escalate capital repairs before a single failed part becomes a pattern. The owners who avoid the worst outcomes aren’t luckier. They’re documented, responsive, and prepared.

Tenants’ Rights, Explained for Owners

Understanding the tenant side keeps you out of trouble. Tenants can file HPD heat complaints, seek HP actions in Housing Court, and in some cases pursue rent abatements. Rent withholding is legally risky for tenants and depends on the facts, so it’s not automatic. But retaliation against a tenant who complains is prohibited under New York law. Never threaten, harass, or retaliate. Fix the problem and document it.

Tenants also shouldn’t use ovens, stoves, or unvented heaters to warm apartments. If your building has repeated outages, put a temporary heat plan in writing, including safe, approved space heaters where appropriate, to reduce tenant risk and your liability.

The Bottom Line

HPD heat complaints aren’t going away, and the 2026-27 season begins now. Owners who prepare their boilers, log their checks, respond within hours, and certify accurately will spend far less on penalties and far more time running their buildings. Start your compliance checklist today, before the first cold night, not after the first call.
