NYC DOB Violation Codes
NYC DOB violation codes identify the specific building code section that was violated. Understanding these codes helps property owners, managers, and tenants know the severity of a violation and what corrective action is required.
How DOB Violation Codes Are Structured
Each DOB violation has a violation number and a violation type code. The violation number uniquely identifies the violation, while the type code indicates the category of infraction. Violations with an asterisk (*) in the number are closed. Open violations require corrective action.

DOB ECB Violation Severity Classes
When a DOB violation is referred to ECB (Environmental Control Board), it receives a severity classification:
- Class 1 — Immediately Hazardous: Conditions posing immediate danger to life or safety. Requires immediate correction. Highest fines.
- Class 2 — Hazardous: Conditions that are hazardous but not immediately life-threatening. Must be corrected within a specified timeframe.
- Class 3 — Non-Hazardous: Code violations that do not pose a safety risk. Lower fines, longer correction timeline.
