NYC Steam Radiator Inspections Begin in 2027

Steam Radiator Inspections Begin in 2027 — starting that year, New York City’s HPD will require these inspections once every two years for residential units with children under the age of 6. HPD has released updated details on this upcoming requirement, and building owners across all five boroughs should begin preparing now. This guide covers everything you need to know about steam radiator inspections begin in 2027 — from who is affected, to mailing requirements, inspection frequency, and who qualifies to perform these inspections.

If you own or manage a multi-unit building in NYC, staying ahead of compliance deadlines is critical. The same way NYC annual boiler inspections protect your building from DOB fines, the upcoming steam radiator inspection requirement will add another layer of accountability for landlords and property managers citywide.

As steam radiator inspections begin in 2027, it is crucial for all landlords to understand the implications of this requirement.

What NYC Building Owners Must Know Before Steam Radiator Inspections Begin in 2027

Who Is Affected?

Owners of buildings with 3 or more units will be required to inspect steam radiators if a unit has both of the following conditions present:

• A child under the age of 6 lives in the unit, and
• The unit contains at least one steam radiator

Steam radiators located in common areas — such as hallways and lobbies — must also be inspected, not just individual residential units. Building owners should conduct a full inventory of all steam radiators throughout their property, including shared spaces, before 2027 arrives.

To prepare for when steam radiator inspections begin in 2027, building owners should take proactive steps now.

Condos and Co-ops

Local Law 151 of 2025 makes clear that this requirement does not alter existing compliance responsibilities between unit owners and their respective boards or corporations. However, if a condo or co-op unit is being leased to someone other than the titleholder or their immediate family, and that unit has a child under the age of 6 and a steam radiator, inspections will be required. Owners who lease out their units should not assume they are exempt.

For buildings managing multiple compliance obligations at once — including DOB annual boiler inspections, parapet inspections under Local Law 126, and now steam radiator inspections — having a reliable compliance partner matters. OneViewNYC Inspections helps NYC landlords and property managers stay organized and compliant across all DOB and HPD requirements.

The upcoming steam radiator inspections begin in 2027 and will significantly impact how you manage your building’s compliance.

The Mailing Requirement

Owners must collect information from residents about whether children under the age of 6 live in each unit. The good news is that this can be done as part of the established annual safety notice mailing process already required under HPD guidelines.

HPD has confirmed that if a tenant already provided child-age information through the Annual Notice for Prevention of Lead Based Paint Hazards, they are not required to submit this information a second time for the steam radiator requirement. You will, however, need to identify and document which units — and which common areas — contain steam radiators.

Results for non-responsive residents must be submitted to HPD by March 1st. HPD has provided a dedicated email address for steam radiator-specific submissions: Radiatorinfo@HPD.NYC.GOV. Note that HPD’s website references a February 15th reachout date in some places — building owners should monitor HPD communications for any clarification on this point.

HPD Official Forms

It’s essential that owners understand the requirements as steam radiator inspections begin in 2027 to avoid penalties.

HPD has provided an official Annual Notice Form for Steam Radiator Inspections, which can be incorporated into your existing mailing workflow. Owners should also be aware of the Record of Steam Radiator Inspection form that inspectors will be required to complete and file.

Inspection Frequency

With steam radiator inspections begin in 2027, it’s imperative to stay informed about inspection frequency to maintain compliance.

Covered units must be inspected once every two years. If a unit was already inspected within the applicable two-year window, the building owner must document that an inspection is not required for the current cycle. This recordkeeping obligation applies even when no inspection is needed — owners cannot simply skip documentation for previously inspected units.

Think of it similarly to how the DEP CATS Boiler Registration operates on a triennial cycle — compliance is tracked across years, and documentation must be maintained regardless of whether a filing is due in a given period.

Who Can Perform Steam Radiator Inspections in 2027?

Understanding who can perform steam radiator inspections begin in 2027 is vital for building owners.

HPD has defined a clear list of qualified individuals who are authorized to conduct steam radiator inspections once they begin in 2027. The following professionals qualify:

• A licensed master plumber, high-pressure boiler operating engineer, or stationary engineer
• A licensed oil burning equipment installer, or a mechanical contractor
• An individual working under the direct and continuing supervision of any of the licensed professionals listed above
• A heating plant technician or heating maintenance worker employed by the New York City Housing Authority

Additionally, building superintendents can perform steam radiator inspections provided they complete a certification process. This involves reviewing the Steam Radiator Inspection Training Manual (not yet published — check HPD’s website for updates when available) and submitting the Certification of Building Owner / Building Superintendent form to HPD.

If your building already works with licensed boiler professionals for your annual boiler inspection in NYC, those same licensed individuals may qualify to conduct steam radiator inspections as well — potentially streamlining your compliance process.

What Happens During a Steam Radiator Inspection?

HPD’s inspection form provides for general defect commentary on the condition of each steam radiator. There are several critical rules that apply during and after an inspection:

During steam radiator inspections begin in 2027, proper documentation and adherence to rules will be essential.

• Any inspection report that identifies hazardous conditions must be provided directly to the resident and emailed to HPD
• Where an uncontrolled steam leak or severe corrosion is identified, the inspector must immediately de-energize the boiler by activating the remote shutdown switch or electrical disconnect switch
• Copies of all inspection records, including inspector qualification forms, must be kept on file and provided to HPD upon request

This connects directly to your existing boiler system management obligations. If you currently have an active boiler violation, our boiler violation removal NYC service can help you resolve outstanding issues before steam radiator inspections begin in 2027. Entering 2027 with a clean compliance record is strongly advisable.

As you prepare for steam radiator inspections begin in 2027, ensure all records are in order to avoid complications.

Key Dates and Compliance Timeline

Here is how building owners should plan ahead before steam radiator inspections begin in 2027:

Planning your timeline is crucial as steam radiator inspections begin in 2027.

• • Now through Summer 2026: HPD is expected to release official rules and publish the Steam Radiator Inspection Training Manual. Use this time to conduct a full steam radiator inventory across your portfolio — identify which units and common areas are affected.
  • Fall / Winter 2026: Incorporate the steam radiator resident inquiry into your annual safety notice mailing process alongside existing lead paint inquiries.

Be proactive about your actions now that steam radiator inspections begin in 2027.

• March 1, 2027: Deadline to submit non-responsive resident results to HPD at Radiatorinfo@HPD.NYC.GOV.
• 2027 and beyond: Steam radiator inspections required once every two years for all covered units. All inspection records must be documented and maintained on file.

The same principle that applies to your boiler inspection in Queens, Brooklyn, the Bronx, Manhattan, or Staten Island applies here: do not wait for a notice. Proactive preparation is significantly less expensive than reactive enforcement.
