Class 1 = immediately hazardous (up to $25K). Class 2 = major (up to $10K). Class 3 = non-hazardous (up to $2.5K).
Common types: work without permit, failure to maintain, illegal conversion, non-conforming construction.
Many DOB violations are adjudicated through ECB. Check for hearings, defaults, and outstanding fines.
Open Class 1 violations are critical. ECB defaults become liens. RegWatch risk-scores all of this automatically.
RegWatch combines DOB, HPD, and ECB violations into a unified view with risk scoring, helping you quickly assess a building's compliance status.
