NYC boiler annual inspection and filing

Checked against the official pages listed below on 27 Oct 2026. Not legal advice.

Boilers in many NYC buildings need an inspection every calendar year, with a report filed in DOB NOW: Safety. This page covers low-pressure boilers first, which is most of what you will see on a building record, then high-pressure boilers.

The cycle and the filing deadline

DOB's boiler inspection cycle is January 1 to December 31. Low-pressure and high-pressure inspections must be done inside that calendar year. The report is due within 14 calendar days of the inspection date. DOB's example: an inspection on December 31 must reach DOB by January 14 of the next year.

Which low-pressure boilers need an annual inspection

DOB says annual inspections and reports are required for H-stamped and E-stamped boilers, not HLW-stamped hot water heaters, in:

residential buildings with six or more families
commercial and mixed-use buildings, whatever the boiler's BTU capacity
residential buildings classified as single room occupancy (SRO)

DOB says these do not need one: boilers in residential buildings with five families or fewer, and a single boiler inside one dwelling unit that heats only that unit. DOB notes that a boiler of 100,000 BTU or less is still subject to inspection when it sits outside a single apartment in a building with six or more residential units, or in a commercial or mixed-use building.

Who can inspect

The owner hires the inspector. Low-pressure inspections can be done only by qualified installers licensed by DOB or by an authorized boiler insurance company. High-pressure boilers need an internal and an external inspection in the same cycle, about six months apart, and only an authorized insurance company can perform them. For the internal inspection, DOB says the inspector must notify DOB at least 10 days beforehand.

Late and missing filings

Situation	Per DOB
Report filed after 14 days but no later than January 14 of the following year	Late. $50 per month, per boiler, from the day after the deadline, up to $600 per boiler.
Report filed after that window	Expired. A failure-to-file civil penalty of $1,000 per boiler.
High-pressure boilers	The same amounts apply per boiler, per inspection type.

DOB issues violations coded LL6291, LBLVIO or HBLVIO to the property for failure to file the annual inspection report. These are the codes you will see on building pages.

Defects found at inspection

Defects must be corrected within 90 days of the initial inspection, and a subsequent inspection report filed within 14 days of that subsequent inspection. DOB says an affirmation of correction filed more than 104 calendar days after the initial inspection is expired and rejected. If it comes after the correction due date, the failure-to-file affirmation of correction penalty is $1,000 per boiler, plus the $50 monthly late fee up to $600.

An owner or licensee can request up to two 45-day extensions of the subsequent inspection deadline. DOB says each request must be filed in DOB NOW: Safety no later than the current correction deadline, and it is not granted until DOB approves it.

Removed or replaced boilers

DOB says that when a boiler in a multi-dwelling, SRO, commercial or mixed-use building is removed and not replaced, a Boiler Removal Notification (OP49) must be filed in DOB NOW: Build within 30 days, completed by a licensed professional. New or replaced boilers get a First Test Inspection from DOB before use.

Clearing a boiler violation

DOB's page on resolving boiler violations says to provide proof of compliance, such as a copy of the report filed for that cycle year, or to pay the civil penalty and file a current inspection report in DOB NOW: Safety. Owners can request a waiver of failure-to-file penalties in the Violations portal. The criteria are in §103-01 for low-pressure boilers and §103-05 for high-pressure boilers.

On Inspection Lookup

A building page with boilers on file shows the latest inspection filed for each boiler, the report type, whether defects were reported and the filing status. Neighbourhood pages list buildings with active boiler violations, reached from each borough's violations page.
