What Is Local Law 62?
Local Law 62 of 1991 is the New York City law that requires annual inspections of covered low-pressure boilers in residential, commercial, and mixed-use buildings. The inspection must be performed by a DOB-licensed qualified installer or an authorized boiler insurance company, and the report must be filed with the NYC Department of Buildings through DOB NOW: Safety within 14 calendar days of the inspection date.
The law applies specifically to H-stamped and E-stamped low-pressure boilers — not to HLW-stamped hot water heaters, which are a different equipment category under DOB rules. If your building has a covered boiler, the annual inspection and filing deadline should be a fixed item on your operating calendar, not something discovered in November.
Which Buildings Are Required to Comply with Local Law 62?
DOB requires annual low-pressure boiler inspections for the following property types:
- Residential buildings with six or more families
- Commercial buildings
- Mixed-use buildings (commercial space plus one to five residential units), regardless of boiler BTU capacity
- Residential buildings classified as Single Room Occupancy (SRO) dwellings
Important exceptions: Registered low-pressure boilers in residential buildings with five families or fewer do not require the annual inspection. A single boiler located within one dwelling unit that heats only that unit is also excluded. Small boilers are not automatically off the hook — boilers with an input of 100,000 BTUs or less are still subject to inspection when located outside a single apartment in a covered 6-plus-family, commercial, or mixed-use property.
One additional note: a new or replaced boiler that passes its First Test Inspection does not require a separate annual inspection report during that same inspection year.
When Is the Local Law 62 Inspection Due — and How Does Filing Work?
The inspection cycle runs January 1 through December 31 of each calendar year. The filing deadline is separate from the inspection date: once the inspection is completed, the report must be submitted to DOB NOW: Safety within 14 calendar days.
DOB is specific about the edge case: if an inspection is performed on December 31, the report is still due by January 14 of the following year, because the 14-day filing window runs from the inspection date regardless of where it falls in the calendar.
Only DOB-licensed qualified installers or authorized boiler insurance companies can perform the inspection. The building owner is responsible for hiring the inspector and ensuring the report is filed.
What Are the Penalties for Missing a Local Law 62 Filing?
Penalties follow a two-stage structure and compound quickly.
| Violation |
Penalty |
| Annual inspection report filed late (during the late-filing window) |
$50/month per boiler, up to $600 |
| Annual inspection report not filed at all (late-filing window closed) |
$1,000 per boiler, failure-to-file |
| Affirmation of Correction filed late after defect repair |
$1,000 per boiler + $50/month up to $600 |
A single boiler report filed four months late can cost $200. A corrected boiler whose follow-up report is filed two months after the correction deadline can trigger the full $1,000 failure-to-file penalty plus additional monthly late fees. If the annual report is filed after the late-filing window closes entirely, DOB treats it as expired and applies the $1,000 penalty — there is no partial credit for filing after the window.
What Happens If the Boiler Inspection Finds Defects?
If the inspector identifies defects, the building owner has 90 days from the initial inspection date to correct them. After corrections are completed, a follow-up inspection must be performed and a subsequent report filed within 14 days of that follow-up.
DOB’s hard limit: an affirmation filed more than 104 calendar days from the initial inspection date is automatically deemed expired and will be rejected. Owners can request up to two 45-day extensions — but only if the extension request is submitted before the current correction deadline and approved by DOB before that deadline passes.
If an inspection is completed in late November and finds defects, the 90-day correction window runs into late February. Missing that window creates a separate $1,000 penalty exposure on top of any repair costs.
Is Local Law 62 the Same as NYC Cooling Tower Compliance?
No — and the distinction matters operationally. Boiler inspections under Local Law 62 and cooling tower Legionella compliance are two entirely separate regulatory frameworks administered by two different agencies. Treating one as satisfying the other is a preventable way to accumulate violations.
| Requirement |
Agency |
Covered Equipment |
Core Cadence |
| Local Law 62 annual boiler inspection |
NYC Dept. of Buildings (DOB) |
H-stamped and E-stamped low-pressure boilers in qualifying residential, commercial, mixed-use, and SRO properties |
Annual inspection; report due within 14 days; 90 days to correct defects |
| Cooling tower compliance (Local Law 159 of 2025) |
NYC Dept. of Health and Mental Hygiene |
Registered cooling towers |
Legionella testing at least every 31 days while operating; compliance inspections every 90 days |
The portals, inspection records, filing deadlines, and enforcement agencies are entirely different. A building with both a covered boiler and a cooling tower needs to track both obligations separately.
How Does Local Law 62 Relate to Local Law 152?
This is a question building owners with gas-fired boilers need to think about carefully — because if your boiler runs on natural gas, you are likely subject to both laws.
Local Law 152 requires periodic inspections of exposed gas piping throughout your building, administered by the DOB on a four-year rotating schedule tied to your community district. Local Law 62 requires annual inspections of the boiler itself. These are separate systems, separate obligations, and separate filing requirements — but they often intersect in the same mechanical room.
For a building with gas-fired boilers, the practical implication is that you are managing both an annual boiler compliance cycle (LL62) and a four-year gas piping inspection cycle (LL152) that do not align in schedule, scope, or filing portal. The professional handling your LL62 boiler inspection cannot substitute for a licensed plumber performing an LL152 gas piping inspection — and vice versa.
Where the two laws connect is in planning. Scheduling your LL62 boiler inspection with a service provider who understands both requirements gives you visibility into gas-system conditions that may be relevant to your upcoming LL152 window. A boiler service visit is an opportunity to identify aging gas connections, valve issues, or piping concerns that the gas piping inspection will eventually surface — before they become a compliance problem under two laws at once.
How LL62 Fits Into the Larger NYC Compliance Picture
Local Law 62 is one of several overlapping inspection and reporting requirements that govern NYC buildings. For building owners already navigating LL84, LL87, and LL97, here is where LL62 sits in that framework.
Local Law 84 requires annual energy and water benchmarking through ENERGY STAR Portfolio Manager. It is a data reporting obligation — not an inspection. LL62 operates independently on a parallel annual cycle.
Local Law 87 requires large buildings (50,000+ sq ft) to complete a full energy audit and retro-commissioning study every 10 years. The LL87 audit will examine boiler efficiency and may identify maintenance or upgrade items — but it does not satisfy the LL62 annual inspection requirement.
Local Law 152 covers gas piping inspections every four years by community district. Buildings with gas boilers carry both LL62 and LL152 obligations simultaneously on different schedules.

How to Stay Ahead of Local Law 62
Confirm your boiler type and property classification first. H-stamped or E-stamped low-pressure boilers in 6-plus-family, commercial, mixed-use, or SRO buildings are covered. Check your boiler nameplate and DOB property records if you’re uncertain.
Schedule early in the calendar year. Waiting until fall creates access conflicts, rush scheduling, and no buffer if defects are found and the 90-day correction window falls over winter.
Assign clear filing responsibility. Someone needs to own the DOB NOW: Safety submission within 14 days of the inspection date. This is where most violations originate — the inspection gets done, the filing doesn’t.
Track your defect correction window immediately if issues are found. 90 days from inspection, follow-up report due 14 days after the correction inspection. Calendar both dates the day the initial report comes in.
Coordinate with your LL152 gas piping schedule. Know when your community district’s gas piping inspection is due so your boiler service provider can flag any gas-system concerns in advance.

FAQ
Does Local Law 62 apply to a one-to-five-family residential building?
Generally no. DOB exempts registered low-pressure boilers in residential buildings with five or fewer families from the annual inspection requirement. A single boiler inside one dwelling unit that heats only that unit is also excluded.
If my inspection is completed on December 31, when is the filing due?
January 14 of the following year. The filing window is 14 calendar days from the inspection date, not from the end of the calendar year. The inspection date starts the clock.
Can I still be penalized after I fix the defects?
Yes. Correcting the defects is only part of the requirement. A follow-up inspection must be performed and the subsequent report filed within 14 days. Missing that filing triggers a separate $1,000 failure-to-file penalty plus monthly late fees.
What is the difference between an H-stamp and an E-stamp boiler?
Both are low-pressure boiler classifications under DOB rules. H-stamped boilers are typically standard low-pressure steam or hot water boilers. E-stamped boilers are electrically heated low-pressure boilers. Both are subject to the annual LL62 inspection requirement when located in a covered property. HLW-stamped hot water heaters are a different category and are not subject to LL62.
Does the same professional who does my LL152 gas piping inspection handle my LL62 boiler inspection?
No. Local Law 152 gas piping inspections must be performed by a licensed master plumber. Local Law 62 boiler inspections must be performed by a DOB-licensed qualified installer or authorized boiler insurance company. These are separate qualifications, separate scopes of work, and separate filing requirements.
Local Law 142 and LL152: Who Can Legally Perform Your NYC Gas Piping Inspection
If you own or manage a building in New York City, the rules around who can legally perform your Local Law 152 gas piping inspection have changed. Local Law 142 didn’t replace LL152 — it tightened who is allowed to perform the inspection on behalf of a Licensed Master Plumber.
Local Law 62 Explained: NYC Annual Low-Pressure Boiler Inspections, Deadlines, and Penalties
If your NYC building has a covered boiler, you are required to have it inspected every calendar year and file the inspection report within 14 days — no exceptions, no grace period, and no automatic extension unless you request and receive one in advance. That is Local Law 62 in a sentence.
