How to Clear an HPD Heat Violation in NYC

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 HPD gives the owner no grace period to fix it. 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 can bring civil penalties of $350 to $1,250 a day, or $500 to $1,500 a day for a repeat violation, 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.

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

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

HPD gives no grace period to correct a Class C heat violation, 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 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
