Key takeaways
- Confirm whether each boiler is subject to DOB or another inspection authority.
- Track the inspection, filing acceptance, defects, correction, and subsequent inspection separately.
- Keep a new or replaced boiler's First Test path separate from the recurring annual cycle.
- Keep accepted DOB NOW records with the building’s boiler-service documentation.
If you own a multifamily building in New York City, your boiler is not something you can service when it feels convenient.
DOB requires annual inspections and filings for covered low- and high-pressure boilers. Coverage, inspection responsibility, and reporting differ by boiler and property type, so owners should start with the boiler record and DOB's current boiler compliance guidance.
Which Buildings Are Covered
The inspection cycle runs from January 1 through December 31. DOB distinguishes low-pressure and high-pressure compliance rather than applying one filing rule to every piece of heating equipment.
Covered low-pressure boilers include H- and E-stamped boilers in residential buildings with six or more families, commercial and mixed-use buildings, and SRO dwellings. DOB says annual inspection is not required for a registered low-pressure boiler in a residential building with five families or fewer, or for one boiler inside a single dwelling unit that supplies heat only to that unit.
High-pressure boilers require an internal inspection and an external inspection in the same annual cycle, approximately six months apart. DOB says only an authorized insurance company may perform those high-pressure inspections.
HLW-stamped domestic hot-water heaters are not boilers under DOB's boiler program. If the equipment classification or property record is unclear, confirm it in DOB NOW: Safety before assuming that an annual filing is required—or exempt.
What does the annual filing actually require?
The filing is not simply a form submission. Owners of covered low-pressure boilers hire a DOB-licensed qualified installer or an authorized boiler insurance company. High-pressure boiler inspections are performed by an authorized insurance company. Inspection reports for both programs are filed in DOB NOW: Safety within 14 calendar days of the inspection.
If the inspection identifies defects, the initial report still has its own 14-day filing deadline. DOB then requires the defects to be corrected within 90 days of the initial inspection, followed by a subsequent inspection report filed within 14 days of that inspection. DOB says an affirmation of correction filed more than 104 calendar days after the initial inspection is expired and rejected, unless an approved extension changes the current correction deadline. A dangerous condition that threatens life or safety and requires immediate shutdown follows the separate 24-hour notification rule in DOB's current boiler guidance.
How is a First Test different from an annual inspection?
New and replaced boilers follow a registration path before they enter the recurring annual cycle. DOB calls the agency inspection before use the First Test Inspection. If the boiler passes, DOB issues approval and signoff; DOB's current guidance says an annual inspection report is not required for that same inspection year.
If the boiler fails First Test because the installation does not comply with code, the installation issues must be corrected before another First Test is requested through DOB NOW: Inspections. Owners should not treat a contractor startup, service visit, or annual report as a substitute for that DOB approval and signoff.
What Happens If You Miss the Filing Deadline
DOB treats a report filed after its 14-day deadline, but within the stated late-filing period, as late. The current guidance lists a $50-per-month late penalty per boiler, capped at $600; a report submitted after the late-filing period is treated as expired and carries a $1,000 failure-to-file penalty per boiler. High-pressure penalties apply per inspection type. Check the current device record and DOB guidance before acting because waiver eligibility, extensions, and the status of a particular record are fact-specific.
When a boiler condition also interrupts required heat or hot water, the owner may have a separate HPD service obligation in addition to the DOB boiler record. For more on how those agency roles differ, see our HPD vs. DOB guide.
The Correction Process for Existing Boiler Violations
If your building already has a boiler violation on record — from a lapsed filing, a failed inspection, or a DOB inspection triggered by a complaint — the correction process follows a specific path.
- Read the DOB NOW filing, device record, and any violation to identify the missing report, defect, or correction item.
- If the annual inspection found defects, correct them within the applicable deadline and arrange the subsequent inspection with the qualified inspector responsible for that boiler type.
- File the subsequent inspection report in DOB NOW: Safety within 14 days of that inspection and confirm the portal status. If a separate boiler violation or civil penalty remains, follow the resolution or waiver path shown in DOB NOW rather than assuming the report alone closed every record.
For ECB violations issued alongside the filing lapse, a separate resolution process applies — either payment of the fine or an appearance at an ECB hearing. Payment does not automatically close the underlying DOB violation; the inspection filing correction is a separate action. If you have multiple open items, our guide on DOB violation removal covers how that process works end to end.
How Austin Plumbing Handles Boiler Filings
Austin helps owners coordinate covered low-pressure boiler inspections, repair work, and DOB filing records across Brooklyn, Queens, Manhattan, and the Bronx. The exact scope starts with the boiler type, property record, and current DOB NOW status.
For building owners with multiple properties, Austin can organize a portfolio calendar and the supporting inspection and correction records; the owner should still verify acceptance in DOB NOW.
For an existing boiler violation, Austin can review the DOB record, identify the licensed plumbing and filing work within its scope, and coordinate the next required inspection or submission.

Common Questions
Do all NYC boilers follow the same annual filing process?
No. Coverage and inspection responsibility depend on the equipment and building. Owners should confirm the boiler record and governing agency before scheduling or filing.
Is a completed boiler inspection enough?
No. Covered boiler inspection reports must also be filed and accepted through the required system, and defects may require correction and a subsequent inspection.
Where should an owner verify boiler filing status?
Use DOB NOW: Safety and the building’s device records, then compare the public status with the inspector’s report and filing confirmation.
Does a new or replaced boiler need an annual report in its First Test year?
DOB says a new or replaced boiler must pass a First Test Inspection before use. After it passes and DOB issues approval and signoff, an annual inspection report is not required for that same inspection year.
