Heat season, explained.
From October 1 through May 31, every NYC landlord with tenants must keep apartments at legal temperatures, and hot water flows year-round. Heat complaints are the single most common 311 call in winter, and each one can bring an HPD inspector to your boiler room.
How violations actually happen
A tenant calls 311. HPD attempts an inspection; if the reading is below the legal minimum, that's an immediately hazardous class C violation, and the daily penalty clock runs until you restore heat and certify it. Repeat complaints also put your building on HPD's radar for the season.
Protecting yourself before October
- Service the boiler in late summer, not the first cold week, when every heating company in the city is buried.
- Keep fuel deliveries ahead of the forecast if you're on oil.
- Fix tenant-reported heat issues the same day and keep records: the response time is your defense.
- If the building is owner-occupied with tenants, the rules still apply to the tenants' apartments.
