How to Clear an HPD Heat Violation in NYC

Legal temperature requirements, daily fine rates, HVAC contractor obligations, temporary heat rules, and the full HPD certification process.

A heat or hot water violation from HPD is classified as a Class C — Immediately Hazardous — violation. That is the most serious category HPD issues, and it demands action within 24 hours, not 30 days. During heat season, which runs from October 1 through May 31, NYC law imposes strict minimum temperature requirements on every residential landlord in the city. Missing those requirements even once is grounds for a violation. Missing them repeatedly puts your building on the HPD Heat Watch list, triggers daily fines of up to $1,000 per day, and can result in the city sending its own contractors to fix your boiler and billing you at a significant premium. This guide explains every legal obligation and the exact steps to clear a heat violation before it destroys your operating budget.

What the Law Requires: Exact Temperature Thresholds

NYC Administrative Code Section 27-2029 establishes the minimum heating standards. These are not guidelines — they are enforceable legal thresholds with violation consequences for every degree below compliance.

Time PeriodOutside Temp TriggerRequired Indoor TempSeason
6:00 AM – 10:00 PMBelow 55°F outsideMinimum 68°F inside all apartmentsOct 1 – May 31
10:00 PM – 6:00 AMAny temperatureMinimum 62°F inside all apartmentsOct 1 – May 31
Hot water supplyN/A — year-round obligationMinimum 120°F at tap, 24/7/365All year

Note that the overnight requirement — 62°F from 10pm to 6am regardless of outside temperature — is frequently missed because landlords assume tenants simply need heat when it is cold outside. The overnight requirement applies even during unseasonably warm nights in October and May. HPD inspectors use calibrated thermometers, and the reading at the time of inspection is the legal record.

Fines and Penalties for Heat Violations

Violation TypeFine RangeNotes
Class C heat violation (first)$250–$1,000 per day per violationBegins at end of 24-hour correction window
Repeat heat violation (same heat season)$500–$2,000 per dayECB enhanced penalty for repeat non-compliance
AEP-designated buildingMandatory quarterly inspection fees + finesBuildings with chronic heat complaints
Emergency Repair Program (ERP) interventionCity repair cost + 15% administrative feeCity contracts HVAC and bills landlord directly
Criminal court referral (wilful)Up to $10,000 + potential misdemeanorReserved for egregious or repeated cases

The Emergency Repair Program is the most feared outcome for building owners. When HPD cannot reach a landlord or the heating system is not restored within the violation window, they contract emergency HVAC services directly and charge the cost — plus a 15% administrative fee — as a lien on the property. Emergency HVAC rates in NYC are premium, and the administrative overhead adds further cost. One ERP intervention typically costs more than a year of proper boiler maintenance.

Step 1: Diagnose the System Failure Immediately

A Class C heat violation requires correction within 24 hours, which means you need a licensed HVAC technician diagnosing the problem within hours of receiving the NOV — not the next business day. Common causes of NYC heat failures in residential buildings:

  • Oil or gas boiler failure: Check fuel level first (an empty oil tank is a surprisingly common cause), then pilot light, burner, and pressure gauge. Boiler lockout codes indicate specific failure modes.
  • Steam system issues: Faulty thermostatic radiator valves (TRVs), air-locked radiators, or failed main vents cause uneven heat distribution that triggers complaints in cold units even when the boiler is functioning.
  • Zone valve failure: In hydronic (hot water) systems, a failed zone valve cuts heat to specific floors or units while the rest of the building is fine.
  • Thermostat or aquastat failure: A malfunctioning aquastat causes the boiler to cycle incorrectly, resulting in insufficient heat output.
  • Hot water heater failure: Separate from the heating system in most buildings — a failed domestic hot water heater creates a hot water violation even during summer when heating is not at issue.

Step 2: Provide Temporary Heat While the System Is Being Repaired

While your HVAC technician is working on the system, you are legally required to provide temporary heat to affected tenants. This is not optional. Failing to provide temporary heat is treated as a separate, concurrent violation and compounds your legal exposure significantly.

  • Provide electric space heaters to every affected unit. Deliver them personally and have the tenant sign a receipt — keep this documentation.
  • Only use electric space heaters — never propane or kerosene heaters indoors. The carbon monoxide and fire risk creates additional liability far exceeding the cost of proper equipment.
  • Document every delivery: unit number, tenant name, date and time, heater model number. This contemporaneous record protects you at any subsequent ECB hearing.
  • If the building is large and you cannot source enough heaters quickly, contact a local property management supply company or HVAC emergency service — many maintain heater rental inventory for exactly this purpose.

Step 3: What Boiler and HVAC Repair Costs in NYC

Repair TypeTypical NYC Cost RangeNotes
Emergency diagnostic call (nights/weekends)$250–$500 call feeBefore any parts or labor
Boiler burner repair/replacement$500–$2,500Gas or oil burner assembly
Aquastat or thermostat replacement$200–$600Parts + labor
Zone valve replacement (per zone)$300–$800Hydronic systems
Steam trap replacement (per trap)$150–$400Common cause of uneven heat
Full boiler replacement (residential)$8,000–$25,000+Includes DOB permit and inspection
Hot water heater replacement$1,500–$5,000Depends on size and fuel type
ERP emergency contractor (city)$3,000–$10,000+Plus 15% admin fee billed as property lien

Step 4: Certify the Correction with HPD

Once heating has been fully restored to all affected units, file your Certification of Correction through HPD's eCertification portal. For heat violations, HPD also has a Heat Line (718-840-4200) where you can report restoration — call this immediately when heat is restored, as it can slow the fine accrual clock while your formal certification processes.

  • HPD violation number from your NOV
  • Licensed HVAC contractor's name, license number, and signed work order describing the repair
  • For boiler work requiring a permit: DOB boiler inspection certificate if a major repair was performed (boiler replacements always require a DOB permit and inspection)
  • Confirmation that heat has been restored to legal temperature in all affected units, documented with dated temperature readings if possible
  • If you provided temporary heaters: documentation of delivery and retrieval

Buildings that accumulate three or more heat complaints in a single heat season are automatically flagged for the HPD Heat Watch designation. Heat Watch buildings receive proactive inspection calls during cold weather events, and any failure results in immediate violation issuance with shortened correction windows. The only reliable way to avoid Heat Watch status is preventive boiler maintenance performed before October 1 each year.

Frequently asked questions about HPD heat violations

What is the NYC heat season and when does it start?

NYC's heat season runs from October 1 through May 31 each year. During this period, landlords must maintain minimum indoor temperatures of 68°F between 6am and 10pm (when outside temperatures drop below 55°F) and 62°F at all times overnight. Hot water at a minimum of 120°F is required year-round, not just during heat season.

My boiler broke in the evening — do I have to wait until the morning to call someone?

No. A heat failure during the heating season is a Class C immediately hazardous violation the moment HPD becomes aware of it — the correction window is 24 hours. You need a licensed HVAC technician on-site as soon as possible, and you must provide electric space heaters to affected tenants in the meantime. After-hours emergency HVAC rates are expensive, but they are far cheaper than ERP intervention or daily fines.

Can a tenant call 311 about heat even if the outside temperature is above 55°F?

Yes. The overnight requirement (62°F from 10pm to 6am) applies regardless of outside temperature during the heat season. A tenant who is cold at 2am on a 58°F October night can file a valid complaint, and if an inspector finds the temperature below 62°F, a violation will be issued. The daytime threshold only triggers when outside temperatures drop below 55°F.

What is the HPD Heat Line and how does it help?

The HPD Heat Line (718-840-4200) is a direct reporting line for landlords to notify HPD that heat has been restored after a failure. Calling it as soon as heat is restored can help stop the fine accrual clock while your formal eCertification is processed. It does not replace the eCertification filing — you still need to file online — but it creates a contemporaneous record of restoration that is useful at ECB hearings.

Do I need a DOB permit to replace my boiler?

Yes. Boiler replacements always require a NYC Department of Buildings boiler permit and a post-installation inspection. The licensed HVAC contractor must file the permit before work begins. After installation, a DOB boiler inspector visits to sign off. This process typically takes 5–15 business days for inspection scheduling. Without the DOB sign-off, HPD may reject your certification for major boiler work.

How do I prevent my building from being placed on HPD Heat Watch?

Buildings with three or more heat complaints in a single heat season are flagged for Heat Watch designation. The most effective prevention is annual boiler servicing before October 1 — replacing worn parts, bleeding the system, testing all zone valves and thermostats, and ensuring adequate fuel supply. Many HVAC companies offer pre-season boiler tune-ups specifically for this purpose. Keep records of all maintenance to show HPD proactive compliance.
