Step-by-step
Go to DOB NOW or BIS
Navigate to the NYC Department of Buildings portal at DOB NOW (a810-dobnow.nyc.gov) or the legacy Buildings Information System (BIS) at a810-bisweb.nyc.gov. Both systems allow public access to violation records; start with DOB NOW and use BIS for older records.
Search by Address or BIN
Enter the property address, borough, or Building Information Number (BIN). The BIN is a unique identifier assigned to every building in NYC and provides the most accurate results.
Navigate to the Violations Tab
Once the property profile loads, click on the "Violations" tab. This section lists all DOB-issued violations including ECB violations, DOB violations, and compliance orders.
Review Violation Details
Each violation entry shows the violation number, type, date issued, respondent, status (open/closed/dismissed), penalty amount, and a description of the infraction. Pay attention to Class 1 (immediately hazardous) violations.
Check Resolution Status
Look at the disposition column to see if the violation has been resolved, is pending a hearing, or requires a certificate of correction. Open violations can affect property sales and refinancing.

Overview
The NYC Department of Buildings (DOB) issues violations when a building fails to comply with the NYC Building Code, Zoning Resolution, or other applicable laws. These violations can range from minor administrative issues to immediately hazardous conditions that endanger building occupants.
Types of DOB Violations
DOB violations fall into several categories:
- Class 1 Violations - Immediately hazardous conditions requiring same-day correction
- Class 2 Violations - Major violations that must be corrected within 40 days
- Class 3 Violations - Non-hazardous violations that must be corrected upon notice
- ECB/OATH Violations - Violations adjudicated by the Environmental Control Board, often carrying monetary penalties
Why Check DOB Violations?
Checking DOB violations is essential for real estate due diligence, property management, and compliance. Open violations can delay closings, trigger fines, prevent permit issuance, and indicate unsafe conditions. Buyers, lenders, and title companies routinely check for open DOB violations before transactions close.
Common Issues When Searching
The DOB website can be slow and does not combine data from HPD or ECB into a single view. Address formatting must match exactly. Properties with many violations may require pagination. RegWatch solves these issues by normalizing addresses and aggregating data across all NYC agencies in real time.
Frequently asked
How long do DOB violations stay on record?
DOB violations remain on record permanently, even after resolution. The status will change from open to closed or dismissed, but the record persists in the system.
Can I check DOB violations for free?
Yes. The DOB NOW and legacy BIS portals are free to access. RegWatch also offers free violation lookups with additional features for subscribers.
