NYC Building Violations: The Complete Guide for Property Owners

If you own property in New York City, building violations are something you need to understand. They can cost you thousands in fines, block a property sale, or prevent you from pulling new permits. Whether you got a notice in the mail, found a violation during a title search, or just want to know what you're dealing with, this guide covers it all.

We'll walk through what ECB and DOB violations are, how they're different, what the fines look like, and exactly how to resolve them. Everything here is specific to NYC and current as of 2026.

What Is an ECB Violation?

ECB stands for Environmental Control Board. It's the civil tribunal that handles building code violations in New York City. The ECB used to be its own agency, but it merged into the Office of Administrative Trials and Hearings (OATH) back in 2009. Despite the merger, everyone in the construction industry still calls them "ECB violations."

When a city agency catches a building code violation, they issue a summons. That summons gets adjudicated at OATH (the old ECB). An administrative law judge hears the case, determines if you're in violation, and sets the penalty. Hearings happen at 100 Church Street in Manhattan, though OATH also offers virtual hearings.

ECB violations are civil, not criminal. They won't show up on a criminal background check. But they are public record and stay attached to the property address in the DOB's system until they're resolved. That matters when you're trying to sell, refinance, or pull new permits.

The Department of Buildings (DOB) issues the majority of ECB violations, but other agencies like the FDNY and DEP can issue them too. For a deeper look at ECB violations specifically, read our guide on what an ECB violation means.

ECB Violations vs. DOB Violations

People use "ECB violation" and "DOB violation" interchangeably, but they're actually two different things. Understanding the distinction matters because the resolution process is different for each.

The DOB is the agency that inspects properties and identifies problems. The ECB (now OATH) is the tribunal that holds hearings and collects fines. Think of the DOB as the police officer and OATH/ECB as the court.

Feature	ECB Violation	DOB Violation
Issued by	DOB (adjudicated at OATH)	DOB directly
Type	Civil penalty with monetary fine	Enforcement action (stop work, vacate, etc.)
Resolution	OATH hearing, cure period, pay fine	Certificate of Correction to DOB
Typical fine	$250 to $25,000+	No direct fine (but triggers ECB if ignored)
Hearing required	Yes, at OATH (100 Church St or virtual)	No hearing. Correct condition and file paperwork.
Consequences of ignoring	Default judgment, lien, 9% interest	Escalation to ECB violation, permit blocks

In practice, many violations involve both tracks. The DOB issues an enforcement action (like a stop work order) and simultaneously issues an ECB summons for the fine. You'll need to address both the enforcement action and the ECB case separately.

For details on the enforcement side, check our guides on DOB vacate orders and building code violations.

How NYC Building Violations Get Issued

Most violations don't happen randomly. There's a pipeline, and understanding it can help you avoid one in the first place.

The most common trigger is a 311 complaint. A neighbor, tenant, or passerby calls 311 to report a construction issue, unsafe condition, or suspected illegal work. The DOB logs the complaint and sends an inspector. You can learn more about this process in our guide on how DOB complaints work.

DOB inspectors also issue violations during routine inspections, permit-related site visits, and proactive enforcement sweeps. If the inspector finds a code violation, they can issue a DOB violation, an ECB summons, or both on the spot.

Common Reasons Violations Are Issued

• Work without a permit. This is the single most common violation in NYC. Any construction, demolition, or structural alteration requires DOB permits. If you're unsure whether your project needs one, read our guide on whether you need a permit.
• Illegal conversions. Converting a building to more units than the Certificate of Occupancy allows. Very common in Brooklyn, Queens, and the Bronx.
• Failure to maintain. Crumbling facades, broken sidewalks, damaged fire escapes. Building owners are legally responsible for upkeep under NYC building laws.
• Expired permits. Starting or continuing work on a permit that's lapsed without renewal.
• Safety violations. Missing guardrails, blocked exits, no construction fencing, inadequate scaffolding.
• Zoning violations. Building beyond your lot's allowed floor area ratio, height limits, or setback requirements.
• Failure to comply with a prior violation. Not correcting a previously cited condition within the required timeframe.

Once the inspector issues a violation, you'll receive the summons by mail (or in person). It lists the specific code section, the violation class, your hearing date at OATH, and the potential penalty range.

ECB Violation Classes and Fine Amounts

ECB violations are divided into three classes based on severity. The class determines your fine range, your cure period, and how quickly you need to act.

Class 1 (Immediately Hazardous): These are the most serious. The city considers them an immediate risk to public safety. Fines range from $2,500 to $25,000. There is no cure period. You must correct the condition immediately and pay the full penalty.

Class 2 (Major): These are significant violations that aren't immediately dangerous. Fines range from $1,000 to $10,000. You get a 30 to 60 day cure period to fix the condition before the fine becomes final.

Class 3 (Lesser): These are the least severe. Fines range from $500 to $2,500, but here's the important part: if you cure the violation within the 30 to 75 day cure window, the fine can be reduced to $0.

Common Violations and Penalties

Violation Type	Typical Class	Fine Range	Cure Period
Work without a permit	Class 1	$2,500 - $25,000	None
Illegal conversion	Class 1 or 2	$5,000 - $15,000	None or 30 days
Failure to maintain (safety)	Class 1 or 2	$1,000 - $10,000	None or 30-60 days
Failure to maintain (non-safety)	Class 3	$500 - $2,500	30 - 75 days
Construction safety	Class 1 or 2	$2,500 - $10,000	None or 30 days
Expired permit work	Class 2	$1,000 - $5,000	30 - 60 days
Zoning violation	Class 2	$1,000 - $10,000	30 - 60 days
Failure to comply (repeat)	Class 1	Up to $25,000	None

These are per-violation amounts. A single inspection can result in multiple violations on the same property. And if you don't respond within 40 days, OATH enters a default judgment that adds 50% to 100% on top of the standard penalty.

How to Look Up Violations on Your Property

You don't need to wait for a notice in the mail. You can check for violations on any NYC property right now using three free tools.

1. Buildings Information System (BIS). Go to a810-bisweb.nyc.gov and search by address. BIS shows all open and closed violations, complaints, permits, and Certificate of Occupancy records for the property.

2. DOB NOW. The DOB NOW portal shows violation status along with active permit applications and inspection results. It's the DOB's newer system and is gradually replacing BIS for some functions.

3. OATH/ECB Portal. Go to a820-ecbfines.nyc.gov to see ECB-specific information: hearing dates, outstanding balances, payment history, and whether any default judgments have been entered.

For a detailed walkthrough of the BIS system, see our guide on how to search BIS in NYC.

If you're buying property, your title company and attorney will pull these records as part of due diligence. Open violations will appear on the title search and can delay or block closing.

How to Resolve an ECB Violation

Resolving an ECB violation involves both correcting the physical condition and handling the legal/financial side at OATH. Here's the step-by-step process.

1. Review the summons carefully. Identify the violation class, the specific code section cited, and your hearing date. You have 40 days from the date of the summons to respond.
2. Attend your OATH hearing (or request an adjournment if you need more time). You can appear at 100 Church Street in Manhattan or attend virtually. Bring any documentation that supports your case.
3. Correct the violation. Fix the cited condition. This might mean getting renovation permits, removing illegal construction, or completing required repairs.
4. Request a DOB re-inspection. Once the work is done, schedule a re-inspection through DOB NOW to confirm the condition is cured.
5. Pay any fines. Pay through the OATH online portal, the CityPay ECB portal, or in person at 100 Church Street.
6. Confirm closure. Check BIS and the OATH portal to verify the violation status shows as resolved.

Using the Cure Period to Avoid Fines

If you have a Class 2 or Class 3 violation, the cure period is your best opportunity to minimize or eliminate fines. Here's how it works.

After the OATH judge finds you in violation, you'll get a specified cure period (30 to 75 days depending on the class). During this window, you need to correct the condition, get a DOB re-inspection, and submit proof of compliance to OATH.

For Class 3 violations, a successful cure can reduce your fine to $0. For Class 2 violations, a cure typically reduces the penalty significantly, though it won't always eliminate it entirely. Correcting the violation before your hearing date can result in a 50% fine reduction.

You can also negotiate a settlement with OATH. Settlements typically reduce fines by 20% to 50% in exchange for guaranteed payment. This is worth exploring if you're facing a large penalty and can demonstrate good-faith efforts to fix the problem.

The key is acting fast. Don't wait until the last day of the cure period to start work. If you need permits to fix the problem (and you usually do), the permitting process alone can eat up weeks of your timeline.

How to Resolve a DOB Violation

DOB violations (the enforcement side, not the ECB fine side) are resolved by filing a Certificate of Correction with the Department of Buildings. The process is different from ECB resolution.

First, correct the condition cited in the violation. Then, prepare a Certificate of Correction that describes the corrective action you took. Have it notarized and submit it to the DOB within the required deadline.

Deadlines for the Certificate of Correction depend on the violation class:

• Class 1 (Immediately Hazardous): 30 days
• Class 2 (Major): 60 days
• Class 3 (Lesser): 90 days

The DOB reviews your Certificate of Correction and may send an inspector to verify. If accepted, the violation gets dismissed. If rejected, you'll need to resubmit with additional documentation or corrective work.

What Happens If You Ignore NYC Building Violations

Ignoring a building violation in NYC is one of the most expensive mistakes a property owner can make. The penalties compound over time, and the consequences go well beyond the original fine.

Default judgments. If you don't respond to an ECB summons within 40 days, OATH enters a default judgment. The penalty jumps by 50% to 100% over the standard fine amount. A $5,000 violation can easily become $10,000 or more.

Property liens. Unpaid ECB judgments become liens on your property after approximately 75 days. The lien is recorded with the city and shows up on title searches. You can't sell or refinance the property without clearing it.

Interest and compounding. Unpaid judgments accrue 9% annual interest. On a $10,000 judgment, that's $900 per year. Fines also compound monthly if left unpaid, so the total grows faster than most owners expect. The longer you wait, the more you owe.

Permit blocks. Open violations can block new permit applications for the property. If you're planning renovations, additions, or any construction work, unresolved violations will stop you before you start.

Escalation. Ignored DOB violations can escalate to more severe enforcement actions, including stop work orders and DOB vacate orders. In extreme cases, the city can refer the matter for building demolition at the owner's expense.

Permanent records and property transfers. Even after you pay a violation, it remains on DOB records permanently. It gets marked as resolved, but it's never removed. This also means violations transfer to new owners at property sale. If you're buying a building, check for both open and resolved violations during due diligence.

Violations from Unpermitted Work

Work without a permit is the single most common reason for building violations in New York City. And it's also one of the most expensive to resolve.

If a DOB inspector finds construction work that was done without the required permits, they'll issue a Class 1 ECB violation. Fines for work without a permit range from $2,500 to $25,000. There's no cure period for Class 1 violations, so you'll pay the full penalty regardless of how quickly you fix the problem.

To resolve it, you'll typically need to file for permits retroactively, which means hiring a licensed architect or engineer to prepare plans, submitting those plans to the DOB for review, and getting the work inspected and signed off. If the unpermitted work doesn't meet code, you may need to modify it or remove it entirely.

This is where things get complicated. Retroactive permitting often involves asbestos testing, Con Edison coordination, and multiple rounds of DOB review. The whole process can take months. If you're not sure whether your project needed a permit in the first place, our guide on whether you need a permit breaks down the rules.
