🚨 What Is a Class 1 Violation?
A Class 1 violations is the most severe type of Department of Buildings (DOB) infraction in New York City. These violations are considered “immediately hazardous” and often result in hefty penalties, Stop Work Orders, or even evacuation orders in extreme cases.
Examples of Class 1 Violations:
- Work without a permit on structural components
- Unsafe scaffolding or site conditions
- Missing fire-rated assemblies or required fire protection systems
- Exposed electrical wiring or illegal gas work
- Obstruction of egress or locked fire exits
These violations can endanger lives, and failure to address them immediately may escalate enforcement actions by the DOB or FDNYs
