heat and hot water violations cited in Manhattan in the trailing 3 years, read from the city’s open-data API at this deploy.

How a violation reaches this record

Most rows here start with a tenant's call to 311. HPD schedules an inspection, and if an inspector confirms the condition, HPD issues a violation and mails the owner a Notice of Violation. From that point the violation is searchable on HPD Online by address. It stays on the public record used throughout this site until the agency accepts a correction or the agency closes the case another way. See how HPD, DOB, and OATH/ECB fit together.

The monthly pattern

Heat and hot water violations HPD has cited in Manhattan, by calendar month, over the last 36 complete months so every month is counted across the same three years. January carries the most at 6,202. August carries the fewest at 1,111.

By class

HPD sorts every heat and hot water violation into one of three classes, and the class sets the correction window and how urgently an owner must act. In Manhattan, HPD has issued 32,052 Class C heat and hot water violations, immediately hazardous, correct within 24 hours. It has issued 1,455 Class B, hazardous, correct within 30 days, and 885 Class A, not hazardous, correct within 90 days.

Class C is 93.2% of the 34,392 heat and hot water violations recorded in Manhattan.

The certification record

Of 32,052 Class C heat and hot water violations in Manhattan, 16,518 have ever been certified corrected, 51.5%. Correction took a median of 9 days and a 90th percentile of 15 days. 9,267 have sat open more than a year with no certification on file.

2.0% of heat and hot water violations in Manhattan are currently marked Not Complied With, HPD's status once the certify-by date passes without an accepted certification.

After a certification is filed

Filing a certification does not automatically close a case. If HPD reviews the paperwork and finds it insufficient, the case moves to Defect Letter Issued and the owner must refile. If a reinspection later finds the condition still uncorrected despite a certification on file, the case moves to Invalid Certification. A certification accepted after the certify-by date is marked NOV Certified Late rather than on time; one accepted before it is marked NOV Certified On Time. Each of these statuses carries its own page in the status glossary, decoded in plain language.
