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.

Water leak violations HPD has cited in Brooklyn, by calendar month, over the last 36 complete months, so every month is counted across the same three years. October has the most, 6,358. February has the fewest, 4,492.
Water leak violations by class: A, B and C
HPD sorts every water leak violation into one of three classes, and the class sets the correction window and how urgently an owner must act. In Brooklyn, HPD has issued 10,187 Class C water leak violations, immediately hazardous, correct within 24 hours. It has issued 49,375 Class B, hazardous, correct within 30 days, and 8,983 Class A, not hazardous, correct within 90 days.
Class C is 14.9% of the 68,545 water leak violations recorded in Brooklyn.
How often Brooklyn water leak violations get certified corrected
A certification is the owner’s statement that the repair is done, and in Brooklyn one has been filed on 33.3% of the 10,187 Class C water leak violations. The median wait from inspection to that filing is 14 days; nine in ten land inside 33. The other side of the number: 1,336 violations open past a year with nothing filed.
3.0% of Brooklyn’s water leak violations are now marked Not Complied With, the status HPD sets once the certify-by date passes with no accepted certification.
What happens after an HPD certification is filed
What happens next depends on the date and the review. A certification filed by the certify-by date shows as on time, one filed after it as late. HPD can then find the paperwork insufficient, which is Defect Letter Issued and a second filing, or send an inspector who finds the condition still there, which is Invalid Certification. Each of those has its own page in the glossary.
