Common questions about NYC water leak violations
How many water leak violations does NYC have?
HPD has written 215,089 water leak violations under the housing maintenance code through September 27, 2026, and 27,629 of them are Class C, the immediately hazardous class. That is a count of the city's own published violations in our copy of the data, not an estimate.
Is a water leak violation serious?
It depends on the class HPD's inspector assigned. 12.8% of water leak violations are Class C, which carries a 24-hour correction window; the rest are Class A or B, at 90 and 30 days. What each class means has its own page.
How long does a water leak violation take to clear?
For Class C, the citywide median from inspection to a filed certification is 14 days. 34.5% of Class C water leak violations have ever been certified corrected, and 3,586 have stood open more than a year with nothing filed.
Does this page report a water leak condition or clear a violation?
No. It counts violations. A condition inside an apartment is reported to 311, and a correction is certified with HPD directly. This site files nothing and represents no one, and nothing here is advice.
What these numbers do not tell you
They do not say whether a condition is gone. A violation with no certification may have been fixed the same week with nothing filed, or never touched, and HPD’s data cannot tell the two apart. They carry no penalty amounts. They say nothing about what an owner intends or what happens next. This page names no building and no owner; to look up one building, use the form above.
