What is a DOB Class 1 violation?
A DOB violation issued for a condition the Department of Buildings determines is immediately life-threatening or presents imminent danger to occupants or the public.
Authority: Department of Buildings (DOB)
Severity: Immediately Hazardous
Citation: 1 RCNY § 102-01(c); NYC Administrative Code § 28-204.1
Who gets this violation?
Any building where an inspector identifies a Class 1 condition — most common in buildings with unsafe façades, missing fire escapes, illegal occupancies, blocked egress, structural deficiencies, or Stop Work Order violations.
Common causes
- Deteriorated or falling façade elements (bricks, lintels, parapets)
- Work without a permit in occupied space
- Illegal conversion of commercial to residential (or vice versa)
- Blocked or missing means of egress (fire escapes, stairs)
- Failure to comply with a previous Stop Work Order
- Unsafe construction practices creating hazard to workers or public
Consequences of ignoring it
- Penalties up to $25,000 per violation
- Mandatory correction within specified short timeframe (often 24–72 hours)
- Vacate order if occupants are in danger
- Full Stop Work Order on the entire building
- Criminal referral in extreme cases (construction fatalities)
- Judgment liens on title if fines unpaid
How to resolve
- Retain a licensed architect or professional engineer immediately
- Correct the underlying condition to code compliance
- File an application to correct if the violation requires permitted work
- Obtain DOB re-inspection and sign-off
- Schedule ECB/OATH hearing to challenge fine or plead mitigating factors
- Pay imposed penalty or make payment arrangement with DOF
Typical cost
$5,000 – $75,000+ per violation (penalty + remediation)
This range includes filing penalties, remediation/repair work, and related legal or consulting fees. Actual cost varies with severity, timing, and responsiveness — resolving within mandated cure windows is always cheaper than allowing fines to compound.
Frequently Asked Questions
Can I check if my building has a DOB Class 1 violation?
Yes. Search any NYC address on RegWatch to see current DOB violations on the property, including their class, issue date, status, and any associated fines. This covers both DOB and HPD violation systems and is sourced directly from the authoritative agency records.
How long do I have to correct a DOB Class 1 violation?
Correction windows vary by severity. Immediately hazardous violations typically require correction within 24 hours to 21 days depending on the specific condition. Check your specific Notice of Violation for the exact deadline.
Does a DOB Class 1 violation become a lien on my property?
Unpaid penalties associated with DOB Class 1 violations become judgment liens on the property when they go unpaid for 90+ days (ECB liens) or through DOF collection. These liens appear on title searches and can block refinance or sale closings until satisfied.
What's the difference between a DOB Class 1 violation and a Notice of Violation (NOV)?
A Notice of Violation (NOV) is the initial citation issued by the agency inspector. The DOB Class 1 classification refers to the severity tier assigned to the NOV. Once issued, the NOV creates both a DOB/HPD violation record and an ECB/OATH summons that carries the imposed penalty.
Where can I file a certification of correction?
For DOB violations, file via DOB NOW. For HPD violations, file via HPD Online with photo evidence of the correction. For ECB/OATH summonses, you must attend a hearing or pay the penalty — correction alone does not dismiss an ECB fine.
