The NYC Department of Buildings is the city agency responsible for ensuring the safe and lawful use of buildings and properties across all five boroughs of New York City.
The New York City Department of Buildings (DOB) regulates the construction, alteration, maintenance, and demolition of all buildings in New York City. Operating under the NYC Construction Codes and Zoning Resolution, the DOB enforces compliance standards that protect the safety of residents, workers, and the general public.
The DOB issues permits for construction work, conducts inspections to verify code compliance, and takes enforcement action—including issuing violations—when buildings or construction sites fail to meet legal requirements. The agency processes millions of transactions annually across Manhattan, Brooklyn, Queens, the Bronx, and Staten Island.
DOB data is publicly accessible through the Buildings Information System (BIS), the official online portal where anyone can look up a property's permit history, complaints, inspections, and violation records by address or block and lot number.
A DOB violation is a formal notice issued by the Department of Buildings when a property or active construction project fails to comply with the NYC Building Code, Zoning Resolution, or other applicable laws and regulations. Each violation includes a Commissioner's order to correct the violating condition within a specified timeframe.
DOB violations are entered into the public record through BIS and appear on property title searches. Open violations can prevent property owners from obtaining new or amended Certificates of Occupancy, selling their property, or refinancing an existing mortgage.
Poses direct threat to life, health, or safety. Requires immediate corrective action. Fines up to $25,000+ with daily penalties.
Affects safety but doesn't require immediate action. Fines from $1,500–$10,000. Some are eligible for cure.
Lesser impact on safety. All are eligible for cure without a hearing if corrected within 60 days. Fines from $500–$1,500.
Building violations can arise from dozens of code sections. Here are the most frequently issued DOB violation types that property owners and contractors encounter.
One of the most common DOB violations in NYC. Performing construction, alteration, or plumbing/electrical work without obtaining the required DOB permit can result in Class 1, 2, or 3 violations with fines up to $25,000 and stop work orders.
Modifying a building's use or layout without DOB approval—such as illegal basement apartments, converting commercial space to residential, or adding unpermitted floors. Carries severe penalties and daily fines of $1,000/day.
Property owners are required to keep buildings in safe, code-compliant condition. Crumbling facades, defective fire escapes, broken handrails, and unsafe conditions trigger DOB violations that escalate quickly if uncorrected.
After correcting a violation, owners must file a Certificate of Correction with DOB. Failure to certify within the required timeframe results in additional violations and penalties—even if the original issue was fixed.
Buildings with elevators or boilers must file annual inspection reports and maintain safety compliance. Late filings, failed inspections, or skipped maintenance trigger DOB violations with escalating fines.
Under Local Law 11 (FISP), buildings over six stories must conduct periodic facade inspections. Non-compliance, unsafe facade conditions, or failure to file inspection reports results in DOB violations and steep penalties.
Whether you need a one-time DOB violation search or ongoing monitoring, DOB.Watch (powered by ViolationWatch) makes it simple.

NYC building compliance isn't just about DOB. Our system monitors violations across every major city enforcement agency so nothing slips through.
Construction code violations, work without permit, illegal alterations, unsafe conditions, elevator/boiler compliance, and facade (FISP) violations.
Housing maintenance code violations including lead paint, mold, heat/hot water complaints, pest infestations, and habitability issues in residential buildings.
Administrative tribunal summonses with financial penalties attached. ECB violations carry fines and require hearings if not cured within the specified timeframe.
Fire safety violations including missing smoke/CO detectors, blocked egress, fire suppression system failures, and non-compliant fire escape conditions.
Noise complaints, illegal construction reports, building condition complaints, and other 311 service requests that may trigger DOB or HPD inspections.
Sanitation violations for improper waste disposal, dirty sidewalks, recycling non-compliance, and commercial waste handling at NYC properties.
NYC issues over 200,000 building violations every year. One missed notice can mean thousands in fines, project delays, or blocked property sales. Let DOB.Watch monitor your addresses 24/7.
If you own, manage, or invest in property anywhere in New York City, DOB violations are something you will encounter sooner or later. Understanding what they are, how they work, and how to resolve them efficiently is essential to protecting both your investment and your compliance standing with the city.
DOB violations are typically issued by Department of Buildings inspectors during routine inspections, complaint-driven inspections (often triggered by 311 reports), or proactive enforcement sweeps. An inspector who observes a condition that violates the NYC Construction Codes, Zoning Resolution, or other applicable regulations will issue a Notice of Violation (NOV) on the spot or following an investigation.
The NOV is then entered into the city's Buildings Information System (BIS), where it becomes part of the property's permanent public record. This record is searchable by anyone—prospective buyers, lenders, tenants, and regulators—and remains visible until the violation is corrected and certified.
One of the most common sources of confusion for NYC property owners is the difference between a DOB violation and an ECB violation. While they are related, they serve different functions in the enforcement process.
A DOB violation is an order from the Commissioner of the Department of Buildings to correct a condition. It appears on the property's BIS record and must be resolved for the property to obtain a Certificate of Occupancy, sell, or refinance.
An ECB violation (now administered by OATH, the Office of Administrative Trials and Hearings) is a summons that carries financial penalties. Many DOB-issued violations also carry an associated ECB summons. ECB violations require the respondent to either cure the condition within the specified timeframe, attend a hearing, or pay the assessed penalty.
Key point: A DOB violation can exist without an ECB penalty, but most enforcement actions generate both a DOB record and an ECB summons. You need to resolve both—correcting the condition and addressing the financial penalty—to achieve full compliance.
The NYC Department of Buildings classifies violations into three classes based on severity. Understanding these classes is critical because each carries different correction timelines, penalty amounts, and resolution options.
Class 1 — Immediately Hazardous: These violations represent the most severe conditions—those that pose an immediate threat to life, health, safety, property, or the public interest. Examples include structural instability, illegal gas work, and conditions that could lead to building collapse. Class 1 violations require immediate corrective action ("Correct Forthwith") and carry the highest penalties, often $10,000 to $25,000 or more. Certain Class 1 offenses, like illegal alterations, also accrue daily penalties of $1,000/day for up to 45 days.
Class 2 — Major Violations: These violations affect life, health, or safety but don't require immediate correction. They include conditions like non-compliant exit doors, expired permits with ongoing work, and code deficiencies that need remediation within a specified timeframe. Penalties typically range from $1,500 to $10,000. Some Class 2 violations are eligible for cure—meaning you can avoid a hearing by correcting the condition and certifying correction within 60 days.
Class 3 — Lesser Violations: These have a lower impact on safety and carry the smallest penalties, generally $500 to $1,500. All Class 3 violations are eligible for cure, and correction plus certification within 60 days eliminates the need for a hearing entirely.
There are several ways to look up DOB violations for a specific NYC address:
Option 1: DOB.Watch Free Lookup Tool — The fastest way to check DOB violations on any address. Enter the property address into the search tool above and instantly see active violations from DOB, HPD, ECB, FDNY, and 311—all in one unified view. No login required.
Option 2: NYC BIS (Official DOB Portal) — Visit the city's Buildings Information System at a810-bisweb.nyc.gov and search by address or block/lot number. This shows DOB-specific data only and doesn't include HPD, FDNY, or 311 records.
Option 3: NYC Open Data — For developers and researchers, NYC publishes DOB violation data through its Open Data portal (data.cityofnewyork.us). However, this data typically has a multi-day delay and requires technical knowledge to query effectively.
A one-time search tells you what exists today. But violations can be issued at any time—triggered by 311 complaints, routine inspections, neighboring construction, or proactive enforcement campaigns. Without continuous monitoring, you might not discover a new violation until:
DOB.Watch (powered by ViolationWatch) eliminates this risk by continuously scanning city databases and sending instant alerts via SMS, email, or WhatsApp the moment a new violation, complaint, or inspection appears on any of your monitored addresses.
Property owners use DOB.Watch to stay ahead of violations that could block sales, refinancing, or Certificate of Occupancy issuance. Early detection means lower fines—many violations can be cured at zero or reduced cost if caught quickly.
Contractors and builders monitor their active job sites to catch 311 complaints and DOB inspections before they escalate into stop work orders or project shutdowns. Being notified the day a complaint is filed—rather than when an inspector arrives—gives you time to prepare.
Real estate professionals and property managers use monitoring to track compliance across entire portfolios. Managing multiple buildings means tracking violations from DOB, HPD, FDNY, ECB, and 311 simultaneously—a task that's nearly impossible to do manually across separate city databases.
Property buyers use the free lookup tool during due diligence to identify open violations before closing. Open DOB violations affect property value, financing eligibility, and may require costly remediation post-purchase.
Many DOB violations offer reduced penalties for early action. Class 3 violations and certain Class 2 violations can be "cured"—meaning if you correct the condition and file a Certificate of Correction within 60 days, the penalty is either eliminated or significantly reduced. For non-curable violations, correcting the condition before your first OATH hearing qualifies you for mitigated penalties—typically 50% of the standard fine.
Missing these deadlines is costly. Default judgments—issued when you fail to appear at a hearing—result in the maximum penalty tier plus administrative fees. For Class 1 violations, defaults can exceed $25,000 per offense.
Bottom line: The difference between a $0 cure and a $25,000 default often comes down to knowing about the violation early enough to act. That's exactly what automated monitoring provides.
A DOB violation is a notice issued by the New York City Department of Buildings when a property or construction project doesn't comply with the NYC Construction Codes, Zoning Resolution, or other applicable laws. It includes an order from the Commissioner to correct the condition and becomes part of the property's permanent public record in the Buildings Information System (BIS). Open DOB violations can prevent selling, refinancing, or obtaining a Certificate of Occupancy.
You can search DOB violations for free using the DOB.Watch lookup tool at the top of this page—just enter any NYC address to see active violations across DOB, HPD, ECB, FDNY, and 311 in one search. Alternatively, you can use the city's official BIS portal (a810-bisweb.nyc.gov) by clicking "Property Profile Overview" and entering the address, though this only shows DOB-specific data.
A DOB violation is a Commissioner's order to correct a building code deficiency—it's an administrative record on the property. An ECB violation (now administered by OATH) is a summons carrying financial penalties that may require a hearing. Many enforcement actions generate both: a DOB record for the property's compliance file and an ECB summons with dollar amounts. You need to resolve both separately to achieve full compliance.
DOB violations are classified into three severity levels. Class 1 (Immediately Hazardous) poses direct danger and requires immediate correction—fines can exceed $25,000 with daily penalties. Class 2 (Major) affects safety but allows more time to correct—fines range from $1,500–$10,000. Class 3 (Lesser) has minimal safety impact—fines are typically $500–$1,500, and all Class 3 violations can be cured without a hearing by correcting and certifying within 60 days.
DOB fine amounts vary widely depending on the violation class, specific code section, and aggravation level. Class 3 violations typically carry $500–$1,500 fines. Class 2 fines range from $1,500–$10,000. Class 1 immediately hazardous violations can reach $25,000 or more, plus daily penalties (e.g., $1,000/day for illegal alterations). Default judgments—when you miss a hearing—impose the maximum penalty tier plus administrative fees. Early correction and cure can reduce or eliminate penalties entirely.
Yes. Open DOB violations appear on property title searches and can block or significantly delay a sale or refinancing. The Department won't issue new or amended Certificates of Occupancy while violations remain active, which is often required for closing. Buyers and lenders typically require all violations to be resolved—or escrowed against—before proceeding with a transaction.
A cure is a resolution option for eligible violations (all Class 3 and some Class 2). If you correct the violating condition and file an acceptable Certificate of Correction with DOB within 60 days of the notice, you avoid a hearing and the financial penalty is eliminated or reduced to zero. Curing constitutes an admission of the violation and counts as a predicate for any future aggravated violations at the same property.
To resolve a DOB violation, you must: (1) correct the violating condition as specified in the notice, (2) file a Certificate of Correction with the DOB's Administrative Enforcement Unit (AEU), including documentation such as photos, permits, and contractor statements, and (3) if the violation is not cure-eligible, attend the OATH/ECB hearing and pay any assessed penalty. If you corrected the condition before the hearing, you may qualify for mitigated penalties—typically 50% of the standard fine.
Ignoring a DOB violation leads to escalating consequences. The violation remains on your property's public record indefinitely. If there's an associated ECB summons and you miss the hearing, a default judgment is entered at the maximum penalty tier (up to $25,000+). The city may issue additional violations for failure to certify correction. Open violations block Certificates of Occupancy, complicate property sales, and can trigger stop work orders on active construction. For Class 1 violations, daily penalties accrue until correction.
A Certificate of Correction is an official DOB form certifying that you've corrected the condition cited in a violation. It must be submitted to DOB's AEU with supporting documentation (photos, permits, invoices, test results) within the timeframe specified on the violation. For cure-eligible violations, submitting within 60 days avoids a hearing. For all other violations, the Certificate must be filed to close the DOB record, even after paying ECB penalties.

BIS is the official online database maintained by the NYC Department of Buildings at a810-bisweb.nyc.gov. It contains public records for every property in NYC, including permit applications, inspections, complaints, violations, and Certificates of Occupancy. Anyone can search BIS by address, block/lot, or BIN number. However, BIS only covers DOB data—it doesn't include HPD housing violations, FDNY fire safety violations, or 311 complaints, which are in separate databases.
Absolutely. 311 complaints about construction noise, illegal work, unsafe conditions, or building code issues are routed to the DOB for investigation. If an inspector confirms the complaint, they can issue a DOB violation on the spot. This is one of the most common triggers for violations—and why monitoring 311 complaints alongside DOB records is critical for proactive compliance.
A Stop Work Order (SWO) is issued by DOB when construction work must immediately cease—usually due to safety hazards, working without a permit, or significant code violations. SWOs are a type of enforcement action related to DOB violations. All work at the site must stop until the underlying issues are resolved, the SWO is lifted, and any associated violations are corrected. Continuing work during a SWO results in additional violations and significantly higher penalties.
