How an HPD water leak violation gets issued

Most of these violations start with a tenant's call to 311. HPD schedules an inspection, and if the inspector confirms the condition, HPD issues a violation and mails the owner a Notice of Violation. From then on anyone can look it up on HPD Online by address, and it stays open until HPD accepts a correction or closes the case another way. See how HPD, DOB, and OATH/ECB fit together.

What happens after an HPD certification is filed

Filing does not end the matter. The certify-by date decides whether the violation shows NOV Certified On Time or NOV Certified Late. If the paperwork falls short, the case moves to Defect Letter Issued and the owner files again. If a reinspection contradicts it, the case moves to Invalid Certification. The status glossary has all of them.
