In New York City, the boiler inspection deadline is not really one date, it is two: the inspection has to happen during the calendar-year cycle, and the report has to be filed within 14 days of that inspection. Missing either one starts the penalty clock. Here is exactly how the timing works and what it costs to get it wrong.
Every covered boiler in New York City must be inspected once during the annual cycle, which runs January 1 through December 31. The signed inspection report must then be filed in DOB NOW: Safety within 14 calendar days of the date the inspection was performed. An inspection done on December 31, for example, has to be received by the Department of Buildings no later than January 14 of the following year.
That 14-day window is the detail that catches owners off guard. The inspection itself can be on time, but if the report is not filed within 14 days, the filing is late and penalties begin to accrue.
NYC runs boiler compliance on a calendar-year cycle. The inspection has to be performed at some point between January 1 and December 31. There is no single citywide due date for the inspection itself, which is why owners have flexibility in when they schedule it. The practical advice is to schedule earlier in the year rather than later, because the back half of December is the busiest time for inspectors and leaves no margin if a problem is found.
Once the inspection is performed, the clock starts. The inspection report must be filed electronically in DOB NOW: Safety within 14 calendar days of the inspection date. This is the deadline that matters most, because it is the one most commonly missed.
Reports filed after the 14-day window, but no later than January 14 of the year following the cycle, are treated as late filings and carry a monthly penalty. Anything filed after that point is treated as a failure to file, with a larger flat penalty per boiler.
The 14-day filing rule applies to both classes of boiler, but the inspection itself differs.
| Low-pressure boilers | High-pressure boilers | |
|---|---|---|
| Frequency | Annual inspection | Annual, but two separate inspections |
| What is inspected | One annual inspection | An internal and an external inspection, performed roughly six months apart in the same cycle |
| Who can inspect | A DOB-licensed qualified installer or an authorized boiler insurance company | An authorized insurance company |
| Filing | Within 14 days of the inspection | Within 14 days of each inspection |
For high-pressure boilers, the inspector must also notify DOB at least 10 days before performing the internal inspection. For a fuller breakdown of how the two boiler classes differ, see our guide on how often commercial boilers need to be inspected.
Annual boiler inspections and filings are required for H-stamped and E-stamped boilers (not HLW-stamped hot water heaters) in:
Two common situations do not require an annual inspection: boilers in residential buildings with five families or fewer, and a single boiler located within a single dwelling unit that supplies heat only to that unit. If you are not certain whether a particular boiler is covered, it is worth confirming before the cycle closes, because an unfiled covered boiler is treated the same as a missed inspection.
The penalty structure is tiered, and it is built to reward filing as quickly as possible:
For high-pressure boilers, these penalties apply per boiler and per inspection type, so a missed internal and a missed external filing are counted separately. An owner may request a waiver of failure-to-file penalties through the Violations portal in DOB NOW: Safety, subject to the criteria in the governing rule.
If the inspection finds defects, a second timeline begins. The defects must be corrected within 90 days of the initial inspection date, and a subsequent inspection report must be filed within 14 days of that subsequent inspection. An affirmation of correction filed more than 104 calendar days after the initial inspection is treated as expired and the report is rejected.
This is the one place the 45-day figure legitimately appears: an owner or licensee may request up to two 45-day extensions of the subsequent inspection filing deadline, but the request has to be submitted before the current correction deadline and is not granted until DOB approves it. The extensions apply to the correction filing, not to the original 14-day report.
A new or replaced boiler must pass a First Test Inspection by the Department before it can be used. In the year a boiler passes its First Test Inspection, an annual inspection report is not required for that boiler. After that first year, the boiler joins the normal annual cycle.
The inspection report must be filed in DOB NOW: Safety within 14 calendar days of the date the inspection was performed. The inspection itself must take place during the January 1 to December 31 cycle.
No. The report is due within 14 calendar days of the inspection. The 45-day figure refers only to optional extensions of the subsequent inspection filing deadline when defects are being corrected, not to the original report.
A report filed after 14 days but by January 14 of the following year is a late filing, with a $50 per month per boiler penalty up to $600. A report not filed by then is a failure to file, with a $1,000 per boiler penalty.
Annually, for covered H-stamped and E-stamped boilers in residential buildings with six or more families, commercial buildings, mixed-use buildings, and SRO dwellings.
Low-pressure boiler inspections can be performed by a DOB-licensed qualified installer or an authorized boiler insurance company. High-pressure boiler inspections must be performed by an authorized insurance company.
We perform the inspection, file the report in DOB NOW: Safety within the 14-day window, and track your cycle so the deadline never slips. If you are already late, we can help you file and limit the penalties.
