DOB Violations NYC: A Landlord's Guide to Classes, Fines, and Removal

Most New York City owners discover a DOB violation the same way: a tenant mentions an inspector was in the building, or a lender's title search turns up something nobody knew about. By then the clock has usually been running for weeks.

Here is the part that costs owners the most money, and it is the part almost nobody explains: fixing the physical condition does not close a DOB violation. The repair and the penalty are two separate tracks. Owners fix the problem, assume they are done, never respond to the summons, and get hit with a default judgment on top of the original fine.

This guide covers what DOB violations are, how they differ from HPD violations, what the three classes actually cost, how to look up what is open on your building, and how to close a violation properly.

What Is a DOB Violation?

The Department of Buildings issues a violation when a property fails to meet the NYC Building Code or the Zoning Resolution. The most common triggers for residential and mixed-use owners are:

• Work performed without a permit, including renovations a previous owner never filed
• Unsafe structural conditions
• Facade defects, typically surfaced through Local Law 11 inspection cycles
• Failed or overdue elevator inspections
• Boiler issues and missing annual filings
• Illegal conversions — an extra unit, a cellar apartment, an SRO conversion

Two things make DOB violations different from an ordinary municipal fine.

First, most of them are summonses, not invoices. They carry a hearing date at OATH, and ignoring that date produces a default judgment that is significantly harder and more expensive to unwind than the original penalty.

Second, they attach to the property, not to you. A violation issued to an owner in 2019 is still open against the building in 2026 unless somebody affirmatively closed it. If you bought a building and never pulled its violation history, you may have inherited someone else's problem — and the city does not care who created it. Violations sit alongside the other obligations covered in our overview of NYC landlord-tenant law, but unlike most of those, they carry a hard deadline attached to a summons.

DOB vs. HPD vs. ECB: Who Issued This?

This is the single most common point of confusion, and getting it wrong means missing a deadline on the wrong clock.

ECB is the third term you will see. The Environmental Control Board was the body that historically adjudicated these summonses; that function is now handled by OATH. When you see "DOB-ECB violation," read it as a DOB violation with a monetary penalty that gets resolved through the OATH hearing system. The naming is legacy — the process is what matters.

If what you are dealing with is a heat complaint, a leak, or a lead paint notice, you are in HPD territory and the process is different. We cover that separately in our guide to HPD violations for NYC landlords.

The Three Classes and What They Cost

Class 1 is where owners get hurt. The penalty range runs to $25,000, there is no path to avoid it by fixing the condition quickly, and — as covered below — failing to file the Certificate of Correction generates a second, separate penalty.

Read the summons itself for the specific code section cited and the exact cure date. Penalty schedules are set per code section and change over time; the classes above describe the framework, not a guaranteed number for your particular violation.

How to Look Up Violations on Your Building

Every NYC property has a public compliance record. You should know what is on yours before a lender, a buyer, or a tenant's attorney does.

Where to look:

1. DOB Building Information System (BIS) — search by address or BIN for DOB violations, ECB/OATH summonses, permits, and complaints. The core record.
2. DOB NOW: Public Portal — newer filings and job records that may not surface cleanly in BIS.
3. NYC Open Data — the full DOB violations dataset, useful for portfolios where you want to pull multiple BINs at once.
4. HPD Online — separate system, separate violations. Check it too; a clean DOB record tells you nothing about HPD.

Two ways to stay on top of it, and they are not equivalent:

Your First 72 Hours

The most common version we see goes like this. An owner receives a summons for work an earlier owner or contractor never permitted. They hire someone, fix the condition, and file it away. No one responds to the summons. Months later a default judgment surfaces — usually during a refinance, when it is both urgent and expensive.

What to do instead:

1. Identify the class and the cure date. Both are on the summons. This determines whether correcting the condition can resolve it at all.
2. Note the OATH hearing date separately. This is the deadline that produces default judgments. It is not the same as the cure date.
3. Pull the full violation history for the building. Violations cluster. If an inspector was on site, assume there may be more than one, and check whether older items are still open.
4. Determine who has to sign off. Many corrections require a licensed professional — a registered architect or professional engineer — to certify the work. Booking that person is often the longest lead time in the process, which is why this belongs on day one, not day thirty.
5. Correct the condition and document it properly. Photographs, permits, sign-offs, invoices. The Certificate of Correction is an evidentiary filing; thin documentation gets it rejected and the clock keeps running.
6. Resolve the penalty. Pay it or appear at the hearing. Do not skip this because the repair is complete.

Steps 5 and 6 are the two tracks. Both must finish. Completing one and not the other is the single most expensive mistake in this entire process.

The Certificate of Correction — and the $5,000 Trap

The Certificate of Correction (COC) is the filing that tells DOB the condition has been fixed. It requires supporting documentation and, for many violation types, certification by a licensed professional.

For Class 1 violations, DOB requires proof of compliance "immediately." In practice this is generally treated as roughly 75 to 90 days from the issue date — but do not plan against the informal window. Plan against the summons.

If a COC is rejected — which happens routinely over incomplete documentation, missing sign-offs, or the wrong professional certification — the violation stays open and the exposure continues to build. Rejection is not a soft outcome. Treat the filing as seriously as the repair.

Why Open Violations Cost More Than the Fine

The penalty is usually the smallest number in the equation. Open violations sit on the property record and surface at the worst possible moments:

• Refinancing. Lenders order title and compliance searches. Open violations, particularly Class 1 items and anything facade-related, can hold up a closing or cause a lender to withhold funds in escrow until they are cleared.
• Sale. Buyers' counsel finds them in diligence. They become a price adjustment or a post-closing escrow, and you are negotiating from behind.
• Certificate of Occupancy. Outstanding violations can block a new or amended CO, which stalls any project that depends on one.
• Compounding. Some violations accrue daily penalties. Others, like AEUHAZ, generate entirely new violations from inaction.

This is not theoretical. In a Greenwich Village building we took over management of, the property came to us distressed — five vacancies, negative cash flow of roughly $20,000 a month, mounting violations, and a lender holding funds in escrow. Part of the turnaround was straightforward operational work: renovations, leasing, recovering $35,000 in unpaid utility charges. But the compliance work was what unlocked the balance sheet. We cleared 23 ECB violations, and the lender released $135,000 in escrow. Within 90 days the building swung from roughly −$20,000 to +$35,000 per month.

The violations were not the whole story. They were the piece blocking everything else.

When to Bring in Help

Some of this is genuinely manageable alone. A single Class 3 violation on a small building, with clear documentation and a straightforward fix, does not require a professional team.

The calculus changes when:

• The violation is Class 1, where there is no cure period and the penalty range reaches $25,000
• You have inherited violations from a prior owner and do not know the full extent of what is open
• The correction requires licensed professional certification and coordinated trade work
• You are facing a hearing and would be representing yourself at OATH
• You are managing a portfolio, where the failure mode is not any single violation but losing track across buildings
• A transaction is pending — the deadline is now your lender's or your buyer's, not the city's

Meraki Realty handles HPD and DOB violation resolution and inspection coordination as part of property management for Manhattan owners. That means tracking what is open across a portfolio, coordinating the licensed professionals a correction requires, managing the Certificate of Correction filing, and handling OATH deadlines so nothing defaults while a repair is underway.

"Our building has had a complete transformation since Tim and his team took over... From 5 vacancies, a stack of violations, and negative cash flow — we're now running at a 2% vacancy rate with growing rents."

— H. Gans, Greenwich Village building owner
