NYC Heat Season 2026: What Building Owners Need to Know About 311 Heat Complaint Changes

New York City’s heat season begins October 1 and continues through May 31. Starting October 1, 2026, the NYC Department of Housing Preservation and Development will investigate every heat complaint as an individual case.

For NYC building owners and property managers, that makes apartment-level heating performance especially important this year. A boiler may be operating while certain apartments remain below the required temperature because of problems with heat distribution, controls or conditions within individual units.

Before October 1, owners should review recurring cold areas, unresolved heating issues and the overall performance of their building’s heating system. The goal is not simply to confirm that the equipment turns on. It is to determine whether the building can consistently deliver the heat residents are legally entitled to receive.

What Is Changing for NYC Heat Complaints in 2026?

The City has announced that HPD will begin investigating every heat complaint as an individual case on October 1, 2026. The change is intended to place greater attention on the conditions reported by individual residents rather than treating multiple complaints from the same property as one consolidated building case.

This is a change to the City’s approach to heat-complaint investigations. It does not change the dates of NYC heat season or the minimum indoor temperatures building owners must provide.

The practical implication is straightforward: owners should not assume that normal boiler operation proves every apartment is receiving adequate heat. Recurring problems in one apartment, building line, floor or section of the property may require closer evaluation before colder weather arrives.

What Are NYC’s Heat Season Requirements?

NYC heat season runs from October 1 through May 31. During that period, building owners must provide heat under the following conditions:

  • Between 6 a.m. and 10 p.m.: When the outside temperature is below 55°F, the indoor temperature must be at least 68°F.
  • Between 10 p.m. and 6 a.m.: The indoor temperature must be at least 62°F, regardless of the temperature outside.
  • Hot water: Buildings must provide hot water throughout the year at a constant minimum temperature of 120°F.

These requirements apply to the temperature inside apartments, not simply the temperature of the boiler room or the fact that the heating equipment is running.

Building owners can review the complete requirements on the NYC HPD Heat and Hot Water information page.

Does the New Complaint Policy Change NYC’s Temperature Requirements?

No. The October 1, 2026 change concerns how heat complaints will be investigated. NYC’s existing daytime, nighttime and hot-water requirements remain in place.

What changes is the level of attention that may be placed on an individual complaint. That makes it more important for building teams to understand whether heat is reaching different parts of the property consistently.

A building can appear to be functioning normally from the mechanical room while residents experience very different conditions upstairs.

Why Might Some Apartments Remain Cold When the Boiler Is Working?

A central heating system does not always distribute heat evenly throughout an apartment building.

Apartments may receive or retain heat differently because of sensor placement, steam vents, control valves, water circulation, pipe layout, heating-cycle duration, exterior exposure or their position within the building.

For example, a corner or top-floor apartment may lose heat faster than an interior unit. In a steam-heated building, one radiator may receive steam quickly while another at the end of the distribution system takes significantly longer to warm.

These differences can lead to a familiar pattern in NYC buildings: some residents open their windows because their apartments are too hot while others continue reporting inadequate heat.

Energo’s guide to uneven heating in NYC apartment buildings explains these distribution and control issues in greater detail.

What Should Building Owners Review Before October 1?

Preparation for the 2026 heat season should begin with the parts of the property most likely to generate an apartment-level complaint.

Review last season’s service records and resident reports. Look for apartments, floors or building lines that repeatedly experienced inadequate or delayed heat. A recurring pattern may reveal more than a one-time equipment failure.

A preseason heating-system assessment should also evaluate:

  • Boiler, burner or furnace operation
  • Thermostats and temperature sensors
  • Heating controls and operating schedules
  • Pumps, valves and circulation equipment
  • Steam vents and heat distribution
  • Safety controls and shutoff devices
  • Unresolved leaks, noises or pressure changes
  • Equipment that requires frequent resets

This review is intentionally narrower than a complete winter-readiness plan. Heating-oil supply, tank condition, automatic delivery and broader seasonal planning are covered separately in Preparing Your NYC Building for Winter: Heating Fuel Essentials.

Why Should Recurring Cold Areas Be Evaluated Before Heat Season?

Recurring cold areas rarely become easier to diagnose once the heating system is operating continuously and residents are actively reporting problems.

An early assessment gives the building team time to compare conditions in different apartments, evaluate system controls and determine whether a problem is isolated or part of a larger distribution issue.

It can also prevent an overly simple response, such as increasing boiler runtime throughout the building. That may make a cold apartment warmer, but it can also overheat other units, waste energy and shift complaints from one part of the property to another.

The better objective is to identify why the affected area is not receiving or retaining sufficient heat.

Is a Preseason Heating Assessment the Same as a Local Law 62 Inspection?

No. A preseason heating assessment and a Local Law 62 boiler inspection serve different purposes.

A preseason assessment focuses on system performance and reliability. It may examine whether equipment starts correctly, controls respond properly and heat is distributed consistently throughout the building.

Local Law 62 is a separate annual inspection and filing requirement for covered low-pressure boilers. Qualifying boilers must be inspected by an authorized professional, and the inspection report must be filed with the NYC Department of Buildings within the applicable filing period.

A routine heating-system visit should not automatically be assumed to satisfy Local Law 62. Building owners can review coverage, inspection and filing requirements in Energo’s guide to NYC Local Law 62.

When Should a Building Schedule a Heating-System Assessment?

Consider scheduling an assessment before October 1 when:

  • The same apartments reported inadequate heat last winter
  • One floor or building line consistently warms more slowly
  • The boiler runs, but some radiators remain cold
  • Building staff repeatedly adjust the controls without resolving the issue
  • The system requires frequent resets
  • Previous repairs produced only temporary improvement
  • Unusual noises, leaks or pressure changes remain unresolved
  • Management is uncertain whether heat is reaching the building evenly

Scheduling early gives the building time to identify the cause, obtain any necessary parts and complete recommended work before the system is under peak demand.

Frequently Asked Questions

When does NYC heat season begin in 2026?

NYC heat season begins October 1, 2026, and continues through May 31, 2027. The October 1 through May 31 period applies each year.

What is changing about NYC heat complaints in 2026?

Beginning October 1, 2026, HPD will investigate every heat complaint as an individual case. The change concerns complaint investigations and does not replace the existing indoor-temperature requirements.

What temperature must an NYC apartment maintain during heat season?

Between 6 a.m. and 10 p.m., apartments must be at least 68°F when the outdoor temperature is below 55°F. Between 10 p.m. and 6 a.m., apartments must be at least 62°F regardless of the outside temperature.

Why might one apartment be cold while the rest of the building is warm?

The affected apartment may receive or retain heat differently because of sensor placement, venting, valves, water circulation, piping layout, exterior exposure or its position within the building. The boiler may be operating even though heat is not being distributed evenly.

Does a preseason boiler check satisfy Local Law 62?

Not necessarily. A preseason check focuses on system performance and reliability. Local Law 62 has separate inspection, qualification and filing requirements for covered low-pressure boilers.
