The repeat pattern is straightforward. Owners are rarely penalized for owning older equipment. They are penalized for missed inspections, missed filings, unpermitted work, or unresolved conditions on equipment they already own. Treating every gas, burner, boiler, and emissions obligation as a calendar-driven compliance task — not a repair issue to handle when something breaks — is the operating model that keeps buildings out of OATH.
With the May 1 benchmarking and emissions filing window behind them, NYC building owners are in two camps. Owners who missed the Local Law 84 or Local Law 97 deadline are already in the late window. Owners who filed on time are now in the best stretch of the year to address the underlying gas, boiler, and burner issues that drive emissions and inspection violations before next heating season.
What do NYC building owners get cited for most often on heating, boilers, and gas?
The practical scope is broader than a single boiler ticket. Gas piping periodic inspections under Local Law 152, annual boiler inspections under Local Law 62, DEP boiler registration and combustion testing, Local Law 84 benchmarking, Local Law 97 emissions limits, the city’s clean-heating oil rules, and DOB permit requirements all sit in the same owner-risk ecosystem. When one of those items is missed, the building can move from a correctable compliance gap to a DOB or DEP summons, and then to OATH.
A common real-world example: an owner swaps a burner, alters gas piping, or replaces major boiler components during heating season and treats the job as maintenance — but DOB’s role is to issue permits and enforce construction-code compliance for covered work. Another common pattern is that an owner fixes the physical condition but never closes the paperwork loop, which is how a repaired issue can remain an open violation for months.

What is Local Law 152, and what happens if you miss the inspection?
Local Law 152 requires a periodic visual inspection of a covered building’s exposed gas piping and accessible gas components, performed by a New York City Licensed Master Plumber on a four-year cycle assigned by community district. The inspection covers exposed piping, valves, meters, shut-offs, joints, and visible signs of corrosion, leakage, or unpermitted work — typically in basements, cellars, mechanical rooms, and meter rooms.
Owners get cited under LL152 in three ways: they miss the cycle entirely, the plumber files the GPS1 inspection report but the owner never files the GPS2 certification after corrections, or the inspection identifies an unsafe condition that is not addressed promptly. For most owners, the second is the most common — the physical work was done, but the paperwork was never closed.
For a complete walkthrough of what’s inspected, see our Local Law 152 inspection checklist. For the broader compliance picture, see NYC Local Law 152 new rules and 2026 deadlines and our LL152 fines compliance checklist.
What boiler violations does the DOB issue most often?
Three things drive most boiler-related violations in NYC.
The first is a late or missing annual boiler inspection. Under the Local Law 62 framework, covered low-pressure boilers in residential buildings with six or more families, commercial buildings, and mixed-use buildings must be inspected each calendar year, and the inspection report must be filed to DOB NOW: Safety within 14 calendar days of the inspection. DOB’s penalty structure for late filing is $50 per month per boiler up to $600, with a $1,000 failure-to-file penalty per boiler once the late-filing window closes.
The second is a lapsed DEP registration or missed combustion test. DEP handles air-pollution registration for certain boilers — separate from the DOB annual inspection — and an expired registration can trigger its own summons even if the DOB filing is current.
The third is an Affirmation of Correction that is filed late after a defect is repaired. Owners often complete the physical fix on time and assume the matter is closed, but DOB tracks the administrative filing separately. A corrected boiler whose follow-up filing is late can carry the same $1,000 per-boiler penalty plus monthly late fees.
For the full breakdown of who is covered and how the filings work, see our Local Law 62 annual boiler inspection guide and the existing post on triennial boiler registration mistakes.
What energy compliance violations affect heating-heavy buildings?
Local Law 84 and Local Law 97 are often filed under the “energy” heading, but for most NYC buildings, heating fuel is the largest driver of the numbers reported under both. Owners who treat these as office-paperwork problems frequently find the violation originates in the boiler room.
Local Law 84 requires annual benchmarking for buildings over 25,000 square feet, with submissions due May 1 each year. Late or missing submissions trigger penalties. Local Law 97 sets emissions caps for the same size class of buildings and assesses penalties on emissions over the limit. For a quick read on how the two differ, see Local Law 84 vs Local Law 97. For larger buildings, Local Law 87 adds the energy audit and retro-commissioning cycle, which often surfaces heating-side issues that feed into LL97 exposure.
If you are not sure which of these laws applies to your building, the existing post on which NYC building energy laws apply to your building is the right starting point.
Can you still get cited for burning No. 4 heating oil?
Yes. New York City phased out No. 6 heating oil first and is in the process of phasing out No. 4 oil for buildings still burning it. Owners who have not converted to a permitted fuel can face violations tied to fuel type, and the conversion itself often requires DOB permitted work on the burner, fuel piping, and boiler controls. For the rules and timeline, see our existing posts on NYC’s No. 4 heating oil ban and Local Law 32 No. 4 oil conversion strategy.
When does work on boilers, burners, or gas piping require a DOB permit?
Most material work on covered heating equipment requires a DOB permit and a sign-off at completion. That includes burner replacement, boiler replacement, alterations to fuel or gas piping, conversions between fuels, and changes to combustion controls or venting. A simple component swap during a service call is generally maintenance; rework that changes the system’s configuration, fuel type, or rated capacity is generally permitted work.
The most common violation in this category is straightforward: the job got done quickly during heating season, the permit was never pulled, and DOB later identifies the unpermitted work during an unrelated inspection. Owners then have to legalize the existing installation, which usually costs more than permitting the work correctly the first time.
What should you do if you’ve already received a DOB or DEP violation?
Start with the paper itself. Read the issuing agency, the violation class, the condition cited, and the cure date. Then split the problem into two tracks: the building condition and the paper condition.
First, cure the physical issue through a qualified contractor or filing professional. If the notice involves gas piping, a burner, a boiler, or related construction-code work, confirm whether DOB permit filing or signoff is required before the job is considered fully resolved. A contractor like Energo can inspect eligible equipment, perform corrective work, file with DOB and DEP, and assemble the documentation the cure requires. A contractor is not a substitute for legal advice on a contested hearing.
Second, close the administrative file. That usually means submitting the proof the notice requires — inspection reports, corrected filings, permits, signoffs, and a Certificate of Correction if DOB requires one for that violation type. If the matter has already moved into summons territory, OATH lets owners search summonses, see case status, and respond through a remote or in-person hearing. OATH states that owners do not need a lawyer to appear, although legal representation may be appropriate in complicated or high-dollar cases.
If the owner ignores the case, the cost goes up. OATH is the city forum for many DOB and DEP summonses, so the non-response path is the expensive path. The disciplined sequence is: review, cure, document, file, verify closure.
How Energo helps NYC building owners prevent and resolve these violations
Energo’s fully trained, NORA-certified technicians, licensed master plumbers, and licensed electricians handle the heating, boiler, and gas work that drives most of the violations above. That includes Local Law 152 gas piping inspections with GPS1 and GPS2 filing, annual boiler inspections under Local Law 62, boiler and burner replacement, oil-to-gas and oil-to-electric conversions tied to Local Law 32, and the DOB permitting and signoff work that goes with covered installations. On the energy-compliance side, Energo supports the heating-system improvements that bring buildings back under their Local Law 97 limits and the operational work LL87 audits typically recommend.
Energo serves the NYC area and beyond and supports commercial property owners and managers across a broader documented service area.

FAQ
What’s the most common DOB violation for NYC building owners?
The most common heating-related violations are missed Local Law 152 gas piping inspections or GPS2 filings, late or missed annual boiler inspection reports under Local Law 62, and unpermitted work on boilers, burners, or gas piping. These show up disproportionately because each one is calendar-driven and easy to miss without a compliance system in place.
Does fixing the equipment automatically clear the violation?
No. NYC enforcement separates technical correction from administrative closure. Owners typically need both proof the condition was corrected and the right filing — an Affirmation of Correction, Certificate of Correction, GPS2 certification, or amended inspection report, depending on the violation. The case stays open until the paperwork closes.
What can a contractor do after a DOB heating or gas violation?
A qualified contractor can inspect, diagnose, repair, replace, test, and assemble the technical documents needed to cure the condition, and can handle the DOB or DEP filing where applicable. A contractor should not be sold as legal defense. If the case is already at OATH and the dispute is legal rather than technical, hearing strategy is a separate function.
Which NYC buildings have to comply with Local Law 97?
Local Law 97 sets emissions caps for buildings over 25,000 square feet, the same size class covered by Local Law 84 benchmarking. Owners of covered multifamily, commercial, and mixed-use properties should treat heating-plant decisions as compliance decisions, not just maintenance decisions.
Is Local Law 152 the same as the annual boiler inspection?
No. Local Law 152 is a periodic gas piping inspection performed by a Licensed Master Plumber on a four-year cycle by community district. The annual boiler inspection is a separate requirement under the Local Law 62 framework, filed each year to DOB NOW: Safety. Owners of covered buildings often need both.
NYC DEP Boiler Registration: What Is the CATS System and How Does Renewal Work?
If you received a notice from the New York City Department of Environmental Protection that mentions CATS, a boiler registration or an upcoming renewal, it is easy to wonder what exactly you are being asked to do.
The first thing to know is that CATS is the filing system, not the boiler requirement itself.
Does NYC Local Law 92/94 Apply to Roof Repairs or Full Roof Replacements?
Not every NYC roof repair or replacement automatically triggers Local Laws 92 and 94. For an existing building, the New York City Department of Buildings identifies replacement of the entire existing roof deck or roof assembly as a trigger for the sustainable roofing requirements.
