HPD Online is the city's portal for looking up housing code violations, building registrations, and complaint history. It's specifically focused on residential housing maintenance issues.
Violation sources: HPD Online = HPD only. RegWatch = HPD + DOB + ECB combined.
Context: HPD Online doesn't show DOB construction violations or ECB fines. RegWatch shows all three together.
Lien risk: HPD Online doesn't flag ECB judgment liens. RegWatch cross-references violation fines with lien records.
Additional data: HPD Online = violations only. RegWatch = violations + permits + tax + title + zoning + environmental.
HPD Online is valuable for housing-specific research. RegWatch includes the same HPD data but adds DOB, ECB, and 8 more agencies for complete property intelligence.
